detailed working of perror

can anyone please help me out to find out how perror actually works???
In my client.c program i am receiving one error
send: Bad file decriptor
this is printed by perror
as the errno variable is set to 9 which is EBADF
but i want to know from which file does perror seeks or maps this error??
Or more properly how does the kernel maintains the error logs from where the perror prints the latest error.
Please do reply as soon as possible.

Active Directory Authentication for samba share.

Hi Friends,

I'm supporting one of our customers who is using centrifydc samba with AD. Issue is that we are not able to access samba share from our windows machine. I tried using smbclient with AD username and it gives following error message:

check_ntlm_password: Authentication for user [xxx] -> [xxx] FAILED with error NT_STATUS_NO_SUCH_USER

However user do exist in AD and winbind gives the correct SID and info:

wbinfo -a DOMAIN\\xxx%password
plaintext password authentication succeeded
challenge/response password authentication succeeded

wbinfo -n DOMAIN\\xxx
S-1-5-21-141307505-1238419977-2639880222-26449 SID_USER (1)

getent doesn't list the AD accounts. Please help.

KDE4.x or Gome 3.x

I have only tried gnome 2.x and KDE 4.7 and I like them both. I love how sexy KDE looks but gnome seemed like more of a familiar desktop, which made it easier. What do you guys think I should stick too, I herd that KDE is more like windows which makes it more dumbed down or something. But to be honest I don't agree. As a matter of fact I have had more of a windows like experience with gnome in Linux mint 11 than I have had in open-SUSE 12.1 KDE. I found mint easier and more user friendly while I found KDE(SUSE) More cool, way more cool!, but harder to navigate. I want to hear what you guys have to say in general about these desktops since I am still very new to Linux.

Just installed openSUSE: my thoughts!

Let it be known that I am still new to Linux and trying out new things!

Im using KDE for the first time now guys. I really like what I see with open-SUSE 12.1. It looks the part and I never been more motivated to use Firefox as my default browser for some reason. In open-SUSE 12.1 Firefox seems perfect compared to the other distros I tried like Linux Mint 11 and Ubuntu 11.04. The only problem I have is getting use to how openSUSE deals with installing software. Its easy but not as easy as a Debian based distros. Also I dont understand why I can not create icons on my desktop. Well I could be they have to be inside that little plasma square that KDE provides on the desktop(Why I have no clue). Certain things like right clicking do not present options that you would expect in KED. I thing that KDE looks very modern but I find it harder to navigate then gome, gome 2.x that is since I have not tried gome 3.x yet. But I am torn because I really love the modern look of KDE, it almost reminds me of a mac but Im use to how gome functions in general and ! the applications associated with gnome. Should I stick with open-SUSE, or go back to Mint and just install gnome 3 since I am use to mint? Is there a good reason to stick with open-SUSE besides how damn sexy its KDE version looks?

Iptables config for wan:8888 to lan:80 on Amazon EC2

Hello,

Right now i have configured 2 interfaces on my Amazon EC2 instance and i've opened 7999-8999 ports from web interface:

WAN Interface

Code:

eth0      Link encap:Ethernet  HWaddr 12:31:38:04:C0:75
           inet addr:10.220.195.131  Bcast:10.220.195.255  Mask:255.255.254.0

VPN Interface

Code:

ham1      Link encap:Ethernet  HWaddr 00:23:C3:E1:07:8E
           inet addr:192.168.1.108  Bcast:192.168.1.255  Mask:255.255.255.0

As far as i've read Amazon does NAT 1:1, converting my real ExternalIP into 10.220.195.131.

I can ping in internet and also in 192.168.1.1, and i'm interested how can i configure iptables in order to translate:

ExternalIP:8888 into 192.168.1.1:80

Please help me a bit cause i've tried different configurations and none of them worked until now.

For the start can you guys please tell me if i would need to use the ExternalIP in my iptables or 10.220.195.131 ?

Thanks a lot and happy holidays!

Strangest Problem Yet

Ok, this is the strangest problem I have yet to encounter with Ubuntu.

My computer (running Ubuntu 11.10) is unable to use the Internet through either the Wireless LAN connection or the Ethernet connection. It will connect to the network in both instances, but thats about it. I am unable to access the internet. As soon as I connect this computer, the entire connection becomes unresponsive and I have to disconnect and re-start the router to restore the connection. All other devices connected to the router are unable to access the internet as soon as the Ubuntu computer is connected.

If I boot Ubuntu straight from the USB stick it is installed from, then all internet functions work just fine. Because of this, I have been able to rule out a hardware issue as the cause of the problem.

Sorry if this is a bit confusing. I'm trying my best to describe the situation. I may make a video this evening to help document the problem.

Thanks

it's happening.

SO, I've used linux exclusively since around 2005. my modem started dropping carrier last month, I finally got ahold of ATT. and we resolved the issue....for a few hours..I was using a Dlink modem, they said I should be using a ATT modem, so I dug mine out ( been sitting for 2 years) the modem works all lights come on, but I get re-directed to ATT, and it says " your internet account will not work with your current operating system" o.k isn't there some sort of law against a company forcing you to install windows ? This is the begining of the end of freedom of choice...any one else run into this ?

Unresponsive server. Hacked? Crashed? How do I tell what happened?

Hi, sorry if I'm a little "green,"

I've got an Amazon EC2 linux server. My website stopped responding. I tried to SSH in and also did not get a response. Amazon EC2 Management Console said it was still running fine. I could ping it, but web and ssh were not responding. I rebooted the instance and it came back up working fine.

I'm trying to look through the logs and I'm seeing nothing that helps. Amazon shows a single spike in disk read/write at 7am. My httpd access log showsa stop in file requests at 7am, but domain requests continued. I checked /var/log/secure and /var/log/messages and both don't have anything from 7am until I rebooted 3 hours later. It does show a ton of ssh failed attempts that stopped around 5am.

Is there somewhere else I should look? Is there a change I need to make in logging?

Happy Holidays

Regardless of if you celebrate Christmas, Kwanza, Hannukah or some other December holiday I wanted to wish you all happy holidays and of course a great new year. Thanks for the years of help in the forums.

Adding Old Kernel to Grub2

Hi All,

I installed an old kernel (pre version 3 because 3 has a bug that is causing major headaches for me). So I did the reconfigure grub-pc and it showed the correct images (both the most recent and the one I just installed). When I reboot and go into the grub menu it only shows the most recent kernel and of course memtest.

How do I add the one I just installed to the menu? It's weird that it shows up when I do the dpkg reconfigure grub-pc but that it's not showing up in the menu. Appreciate the help, happy holidays

Thanks in advance.

Extracting unknown text to create variable

I am needing to extract unknown text out of a string and set it as a variable. Here is the pattern I am dealing with:

Code:

Category:</span> Soups and Chowders</p>

I need to set whatever the category is as a variable. In this case it would be:

myCategory="Soups and Chowders"

but it could be Cookies or Main Dishes, etc.

In any case, there's always one whitespace after Category:</span> and never a whitespace between the actual recipe category and </p>

Mandriva 2011 first software update broke system

Hello to the forum--I have not run Mandrake since 1999. Tonight I installed the current release of Mandriva 2011 on a P4 platform with 2 GB of RAM and an NVidia AGP graphics solution. After the install completed I went to the online software updater and updated all of the packages called for including a new kernel. After this the system would not boot into multi user, safe mode or CLI. Considering a number of things I elected to re download the .iso from another mirror, burn to DVD at a slower speed and recheck both the checksum and the data on the disk using that feature on K3B (I have a number of Linux systems). After this I nuked the HD with GPartd and reinstalled. Same result after the first software update. System would not reboot and as far as I can get is the "Welcome to localhost.localadomain. When I try to log in with either my user account or as root I get bounced right back to the same window. So I could not even get to any of the system logs ! to try to figure out what is broken.

I had the current version of Mint on the machine before trying to install Mandriva 2011. Between the first and second attempts on Mandriva to try to make sure that there were no problems with the platform, I ran the Seagate bootable disk utility to check the HD and ran a version of ex-memex to exercise system RAM. Everything passed.

The desktop is beautiful. I would like to get this system running but am at a loss on what to do next. There do not seem to be many system tools available on the iso disk (or maybe I am looking in the wrong place). There was one package that had dependency problems using the installer (although it was auto selected for updating) and I elected not to continue.

Its a bit disappointing when updating from the GUI using the package manager breaks the system this badly. I did a forum search for this problem and was not able to find anything similar. As an aside I have been running the nuxes for many years,Unix, BSD and most recently Ubuntu and Suse. The last time I ran Madrake I had to write the /dev files for an unsupported monitor but thats been a long time ago.

Any help would be deeply appreciated.

Thanks for the kind interest and reading this

Linux install issue - computer won't boot from CD or USB

I'm trying to install 11.10 on a new Lenovo IdeaPad that came with Windows 7. I've tried putting the .iso on a CD and a USB and rebooted multiple times, but the computer isn't booting from the CD or the USB; it keeps reloading Windows.

When I try to run the CD through Windows, there's an option for the CD to install a boot helper. When I try to install that boot helper, I get this message:

"An error occurred:

'WindowsBackend' object has no attribute 'cd_path'

For more information, please see the log file: c:\users\notatp\appdata\local\temp\wubi-11.10-rev241.log"

Any ideas how I can get it to boot and install? I successfully installed to my old computer. The new IdeaPad is not so cooperative.

How do I find the link that lists all my subscribed threads?

I'm sure this exists, but I just can't recall where or how its done.

BTW: This forum software's layout is the most easy to read that I've ever seen. The only request that I have is that you widen the display of text.

Thanks very much.

Long time lurker, finally joined and saying hello.

As per title, and the welcome PM asking me to introduce myself really. lol.

Been reading these forums for a while now, but hadn't realised I never registered, so here I am.

I've been using Linux since about 2005/6. I first started with Kubuntu, lasted a week before it irritated me and moved over to Ubuntu. I eventually moved over to Slackware, before giving Mint a try.

In the last couple of years I've distro hopped between Fedora, Debian and openSUSE. I'm now pretty much settled with openSUSE, using Gnome 3 as my DE. For a while I also used XFCE.

I also mess around with mainly CentOS and Debian servers, though I do keep up to date with 'buntu as work on them as well as SUSE servers.

I'm no saint though, as work with Windows computers, and also run a W7 machine to satisfy my urge for gaming.

Anyway, I've rattled on enough now, but I'll wish you all a happy Christmas and new year. :)

Cheers,

Leeky

Send email from shell to users in Mysql

Hi, I need help about sending mail in linux. I have a ubuntu server with working web site, users are uploading files in one main directory (to folder inbox). With samba I shared that directory and on other mashine is Windows server and application that is reading that files and writting content to database. Based of the result is creating new file with content: package name that is recieved, size, date and time and does the package contained erros or it was OK. That newly created files are again sent over samba to the same directory in ubuntu server (to folder outbox). That all is working!

Now, i need to listen are there new files in folder outbox. If there are new files, I need to send their content to specific email address. I have users in Mysql database. The name of files that are coming to outbox is with mask like this ddmmyyyy.x where x is user id in Mysql. So if "extension" of file is 1, I need to send mail to mail address of user in mysql with user id 1. If its 2 I am sending to user with user id... and after that move file from outbox to archive.

So, it's going like this: new file arrived in outbox, based on the extension of that file, select email address of user from database with user id = extension of file. On that email address send content of that file and move file to archive.

Does anyone can help me to solve this. Thank you!

P.S I have a mail working and I can send email from shell.

New Install reboots to grub only prompt, no errors, splash screen ok

I have been trying to follow this tutorial on grub:

http://www.linuxforums.org/forum/lin...lems-grub.html

I have a dell gx270 with ide hard drive. I checked the kernel to see if ata_piix were enabled, and they were., for my ide controller. When, as tutorial suggests, to kernel /boot/kernel-3.0.6-gentoo, It finds my kernel. When I hit enter, I get kernel panic. I am not sure what to try next.

Can I assume, my hardware is not causing the problem?

I will continue, researching this, while I wait for a reply.
Also, I have a nice blue splash screen. I don't know if that means, my hardware is ok.

I should explain there are panic related errors which I will try to copy from the panic screen.:

VFS: Cannot open root device "null)" or unknown-block(3,3)
Please append a correct "root= boot option; here are the available
partitions:
0800 199382240 sda driver:sd
( it continues with 4 more)

Then Kernel panic - not syncing: VFS Unable to mount root fs on unknown block(3,3)
Pid 1, comm: swapper not tained 3.0.6-gentoo #1

That is only part of what is on the screen, I don't know of any other way of saving complete . I plan to web search some of the errors.

bash printf %q weirdness and UTF-8

I'm trying to get nice escaped strings via bash. The script works fine so long as there aren't high ASCII (UTF-8) characters.

Code:

#!/bin/bash
 KKK="…hkjh'"
 echo ${KKK}
 printf "%b\n" "${KKK}"
 printf -v GGG "%q" "${KKK}"
 printf "%b\n" "${GGG}"

and what I get is

Code:

…hkjh'
 …hkjh'
 $'…hkjh\''

which is not what I was expecting (the leading $ and single quote wrappers).

My shell is LANG=en_US.UTF-8 and it seems to handle the display of UTF-8 fine.

The … is UTF code pt +2026 or 0xE280A6.

How FermiLab changed the computing world

This is a great article about computing at Fermi National Laboratory in Batavia, Illinois. It tells the story about how physicists have helped change the computing world, invented the Internet, and made Linux the common OS thread that it is today. The Tevatron's enduring computing legacy | iSGTW

Disclaimer: I am not an unbiased bystander. My wife is a PhD particle physicist and staff member of the computing division at Fermi Lab where she develops and maintains the actual physics software that lets these huge server farms extract meaningful information from the petabytes of raw data that the experiments generate. She started there in 1991-1992 when run one of the tevatron collider began its life.

Anyway, we all owe a great deal to these incredible boffins!

Choosing a Linux distro for a virtual machine

i use parallels software on windows 7 host machine . for security reasons (yes i browse porn sites) i would like to use a linux distro inside a parallels virtual machine to access the internet.

what Linux distro has :
1- firefox or chromium browser.

2- can establish ssh tunneling (porn are not allowed in our country so i have to use ssh tunnel to bypass that) . i use the following terminal command to do that
ssh -p22 -D3000 -C -N username at address

3- as lightweight as possible.

thank you

Files in mount share folder have the -rwxrwSrwx 1 root root permission

Hi, I have mounted a windows shared folder on my linux box and this is fine however any file that appears in it, has the following permissions/user/group set,
-rwxrwSrwx 1 root root
Please can you advise if this is 'SET UID' and root permissions setting on any files is something on the windows shared folder itself or something on the linux end.
The mount command uses mount -t cifs ,
My intention is that anything file copied into the shared folder will keep the original permissions however this isn't happening.

Storing all the RPM packages installing via yum installer

For storing all the RPM packages installing via yum installer, add this following line to your /etc/yum.conf file.

keepcache=1

For Example:

$ more /etc/yum.conf
[main]
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=3
color=never
keepcache=1

Then all rpm packages installed via yum are stored in /var/cache/yum/*/packages.

you can change the cache directory by specifying
cachedir=<mydir> in yum.conf.

For Example:

$ more /etc/yum.conf
[main]
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=3
color=never
keepcache=1
cachedir=/home/user/Downloads

Install EMC Storage in Fedora Linux

Here we are installing EMC storage in Fedora 13 (which is not recommended by EMC). EMC's software Powerpath will
not support with Fedora. So here we are using the package called Multipath. That is default with fedora.

1. Try to boot from the fedora optical Media.
2. Press Esc button when you will get the first boot loader menu for the boot prompt.
3. In that boot prompt. Type:
# Linux mpath
Then press Enter.
(If you are not getting the basic video driver then do the following step)

# Linux mpath xdriver=vesa nomodeset

4. Install fedora with all the available packages. (In the mean time you can configure the storage also. In storage you have to create virtual disk[s].)
5. Configure the IP addresses.
6. Connect the storage with server through switch.
7. start the iscsi daemons:
# /etc/init.d/iscsid start
# /etc/init.d/iscsi start
8. Configure your iscsi daemons with the following commands:
# iscsiadm -m discovery -t sendtargets -p IP-OF-STORAGE
192.168.0.6:3260,4 iqn.1992-04.com.emc:cx.fcnmm102000029.b1
192.168.0.3:3260,1 iqn.1992-04.com.emc:cx.fcnmm102000029.a0
192.168.0.4:3260,2 iqn.1992-04.com.emc:cx.fcnmm102000029.a1
192.168.0.5:3260,3 iqn.1992-04.com.emc:cx.fcnmm102000029.b0
9. Note down the record id (such as iqn.2001-05.com.doe:test) found by the discovery. You need the same for login. Login, must use a node record id found by the discovery:

# iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.60:3260 –login
10. Then you have to assign the virtual disk to your server. That should be done inside the storage configuration window. In the assign menu give the ip/name of the server. If it is successfully assigned then check the new devices are mounted or not in the server.
# fdisk –l
If it is mounted you will get another two devices like /dev/sdc and /dev/sde. (It may differ as per your drive configurations)
11. Start the service multipathd
# /etc/init.d/multipathd start

12. Then edit your grub.conf (add the word "mpath" to the kernel portion like below)
# vi /etc/grub.conf
kernel /vmlinuz-2.6.33.3-85.fc13.i686.PAE ro root=UUID=388a2022-a23d-4987-a51b-f157b4f32280 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us nomodeset mpath rhgb quiet
13. Here we can do the multipath section. Follow the steps.
Start the multipathd daemon.
# /etc/init.d/multipathd start
# chkconfig multipathd on
14. Execute the following commands to check the status of multipathing. And note down the wwid of the storage.
# multipath –ll
EMC (3600601606d082900d043704fc2f6df11) dm-0 DGC,VRAID
size=3.0T features='1 queue_if_no_path' hwhandler='1 emc' wp=rw
|-+- policy='round-robin 0' prio=2 status=active
| |- 14:0:0:0 sde 8:64 active ready running
| `- 11:0:0:0 sdb 8:16 active ready running
`-+- policy='round-robin 0' prio=0 status=enabled
|- 12:0:0:0 sdc 8:32 active ready running
`- 13:0:0:0 sdd 8:48 active ready running

If getting a message like this. That means the multipath is working properly.

15. Edit the multipathd.conf file as per below.
# vi /etc/multipathd.conf
Edit the last portion of the file like this. (Add the wwid in to the file.)

multipath {
wwid 3600601606d082900d043704fc2f6df11 (add this line)
# wwid 36001517975a9e0001473e5c712478694 (disable this line)
alias EMC
}
16. Restart the multipathd daemon.
# /etc/init.d/multipathd restart
17. Ensure that the storage is mounted.
# fdisk –l
If the multipath is perfectly configured you will get two drives like dm-0 and dm-1 inside /dev.
# fdisk –l

Here you can see /dev/sdb, /dev/sde, /dev/dm-0 and /dev/dm-1. These all are the same disk. If we created one partition in one disk that will automatically reflect on others.
Want to create a partition? That we can do with dev/dm-0. No need to do anything in /dev/dm-1.
Create one partition in /dev/dm-0.
# fdisk /dev/dm-0
You can use different tools for creating partition.
(for eg: parted).

Disk /dev/dm-1: 16298.5 GB

Disk /dev/dm-1 doesn't contain a valid partition table.
Now you can see one partition is created in /dev/dm-0 as /dev/dm-0p1.
It is also mapped in /dev/mapper. See the below details.
# ll /dev/dm* /dev/mapper/
brw-rw----. 1 root disk 253, 0 Dec 2 11:47 /dev/dm-0
brw-rw----. 1 root disk 253, 1 Dec 2 11:47 /dev/dm-1

/dev/mapper/:

lrwxrwxrwx. 1 root root 7 Dec 2 11:47 EMC -> ../dm-0
lrwxrwxrwx. 1 root root 7 Dec 2 11:47 EMCp1 -> ../dm-1
The configuration part is almost over. Now we have to mount /dev/dm-0p1 as a directory.

For that we need to edit the /etc/fstab file.

# vi /etc/fstab

Add one more line at the end of the file. You must mount the partition as a _netdev. See the below details.

#
# /etc/fstab

/dev/dm-1 /home ext4 _netdev 0 0

(Here I am mounting as /home partition. You can mount as a different partition.)

19. After that we have to rebuild the kernel file.
# cd /boot/
Take a back-up of initramfs-2.6.33.3-85.fc13.i686.PAE.img file.
# cp initramfs-2.6.33.3-85.fc13.i686.PAE.img initramfs-2.6.33.3- 85.fc13.i686.PAE.img.old
delete initramfs-2.6.33.3-85.fc13.i686.PAE.img file.
#rm initramfs-2.6.33.3-85.fc13.i686.PAE.img

#mkinitrd --with=dm-multipath -v -f initramfs-2.6.33.3-85.fc13.i686.PAE.img `uname -r`
20. Reboot the server.
21. After rebooting make sure that your storage is mounted as /home partition.
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 117G 6.2G 105G 6% /
tmpfs 7.9G 608K 7.9G 1% /dev/shm

/dev/mapper/EMCp1 16.1T 181M 16.0T 1% /home

22. If the partition is mounted change the kernel to the old settings.

Take a back-up of the new initramfs-2.6.33.3-85.fc13.i686.PAE.img file.
#mv initramfs-2.6.33.3-85.fc13.i686.PAE.img initramfs-2.6.33.3-85.fc13.i686.PAE.img.new

Rename the old backup file to the real name.
#mv initramfs-2.6.33.3-85.fc13.i686.PAE.img.old initramfs-2.6.33.3-85.fc13.i686.PAE.img

Playing DVDS

Hello All
I am using Ubuntu 10.04 and have installed all updates.
I can not play dvds with Movie Player and would like to know what package I have to install to watch dvds. If I can't get it from the repository and have to install it from some place else I will need easy instructions on how to do it. I have tried every package in the repository that said it would play dvds with no luck. The only one that came close to me being able to play a dvd was SMplayer and it said that I needed to update it but could not see how to update it so I couldn't use it either.
I'm a newbie so like I said I will need easy instructions or I should say simple instructions.
Also when I tried to use Movie Player it accessed the internet and said there were no packages for it.
Thank you in advance for your help.:(

Gnome 3 freezes Ubuntu 11.10

So basically, I'm trying to get Ubuntu all set up, it installs no problem and works just fine. But I have a problem when it comes to using Gnome Shell. For some reason, every time I install Gnome Shell it messes everything up, I'll install it, and it'll run fine for about 5 minutes then everything freezes and I have to force shut down the computer.

And it's not a problem of using just Gnome Shell, if I install Gnome Shell, I can't even use Unity without the system crashing.

I have to re-install ubuntu all over again just so everything will work (I've re-installed 3 times now)

So, right now I don't have Gnome Shell installed, but I was just kind of wondering why it does this and if there is something that I can do to fix it? If not, that's okay, Unity is cool.. but I'd prefer to run Gnome.

I'm on a Mac, dualbooting with OSX.

Pork not displaying offline messages

I'm on openSUSE 11.4 and use pork 0.99.8.1 for AIM. The problem is that everytime someone sends an offline message to me, the message itself is not displayed, I just get a notification that I received an offline message

Code:

<buddy_who_sent_offline_message>[Offline IM sent 2m ago]

and from <AOL System Msg>

Code:

You just received 1 IM(s) while you were offline.
  If you do not wish to receive offline messages, please go to IM
  Settings (URL of AIM settings)

. Neither am I able to send messages to a buddy that is offline, I get an error message that tells me how my message wasn't sent because the user whom I sent the message to was not logged in.
I use pork because I don't have any other troubles with the application, but I would like to find a solution to the above issue. Thank you!

BASH script to automate a process

QEMU/KVM All projects abort with internal compiler error

Hello,

I have setup a system consisting of the host on AMD Athlon64. On it several VMs are running. Either SuSE 11.4 or 12.1.

When I try to compile any source project (with gcc 4.5.1 or 4.6.2), lately bacula, the 'make' is sooner or later aborted by "internal compiler error". Sometimes I am lucky with tinkering with compiling options like setting -O2 to -O0. Currently I am running the gcc testsuite. It looks like all test fail.
All projects I tried so far ran without error with the same options on the host.

So I think it is connected with the fact that the compilation is done within a VM. But I don't know how to get an angle on this. Maybe the compiler does not know with processorshould be compiled for?

I do not know what information to post to help you analyze the problem, so please ask.

Thank you,

Tobi

Monitoring iptables processes

Hello there.

I'm looking for a way to monitoring iptables processes.
Since iptables acts directly into the kernel (correct me if I'm wrong), I tried to look into /proc to search for something interesting but found nothing.

Sometimes, some rules just don't work and I cannot know why, I need some monitoring tool, something like a grep, to see exactly what is iptables doing with some packet.

Using grep and sed

Hi everyone. I'm having trouble using these commands to their full extent. Here is my problem:

I'm dumping a log to the terminal and only want a specific set of lines that start with

Code:

V/ CONTENT ( [some number]):

But I want these lines without that junk in front of it. To display only the parts I want, I'm doing the log command piped with grep and sed

Code:

./adb logcat | grep CONTENT | sed -e 's/CONTENT ( [some number]):/ /g'

This leaves me with V/(stuff I want). I'm just not sure how to sed the V/ part out of it because in the sed command '/' symbols are used to separate fields. Anybody have an idea? :D

using fopen and fread with /dev/sda

Last night I accidentally deleted quite a few files I had been working on for the past month or so. So, after freaking out for a little while and after trying unsuccessfully to use grep on the unmounted partition (it ran out of memory...haha) I decided I may as well learn something from this and so I am using another computer to write a program (in c) to read directly from my hard drive (/dev/sda) and search for a specific string while using only a reasonable amount of memory (grep was using all 8GB). I now have my computer I deleted the files on running off of a flash drive so that it doesn't harm the data on the hard drive, but I have a few questions about using fopen and fread to read data from /dev/sda (sorry if I have too many questions...I just want to be certain this will work):

Would fopen treat /dev/sda just like any other file?

When using fread on a /dev/sd* file will it return less than the requested bytes when it gets to the end of the hard drive?

Would fread read directly from /dev/sda or would it try to copy it into memory first? Do I have to worry about memory problems if I try to read another 100MB after already reading 8GB (the amount of memory I have on my computer) even though I have free'd the memory that I had it read into?

My program as I have it functions more or less as follows:

Code:

FILE* inputStream = fopen("/dev/sda", "rb");
 //...stuff to check to make sure it actually opened it
 
 //...
 
 //...the following is inside of a loop...
 char* memoryChunk = malloc(100000000); //allocate 100mb for the chunk to be read
 unsigned long int actualReadBytes = fread(memoryChunk, 1, 100000000, inputStream);
 //...memoryChunk is processed...
 free(memoryChunk);
 if (actualReadBytes < 100000000)
 {
        //...exit the loop since that means the last chunk read was the end of /dev/sda
 }
 
 //...after the loop and everything
 fclose(inputStream);

Booting Linux Mint 12

When booting LM 12 a dark rectangular box is displayed at the bottom of the screen with "HP Media Drive" displayed and a choice of "open with files" and "eject". If I select eject the system hangs.

Desktop Fork for GNOME; Yet Another One Bites the Dust...!

Been reading some interesting news and stumbled across several sites referencing to the founder of Linux Mint forking from the GNOME Desktop. I don't know if this is just rumour or if there is an actual backing behind the new forked desktop.

Just look up "Cinnamon Desktop"
or Links here:
Cinnamon: GNOME Shell Fork With A GNOME2-Like Layout ~ Web Upd8: Ubuntu / Linux blog

Gnome Shell Looks Like Gnome 2 – Cinnamon Desktop | Smashing Web

Sounds like the Cinnamon Desktop will be a further improvement on GNOME MGSE. A new hybrid desktop of GNOME 3 and 2. I was always curious and wondered what Mint's Gnome extensions would do, sorta had that gut feeling it might be the start of a fork.

Yet Another one, it appears as though GNOME's new route is quickly losing followers and supporters.

On my count it is up to 3 forks since GNOME 3's release. (The Magic number being 3)
You've got Unity Desktop, MATE, and Cinnamon (if this holds to be true)
That seriously suggests something concerning...! 3 forks from what used to be the Top Desktop Environment in just a few months. That should be ringing alarm bells for GNOME developers.

External USB Drive Will Not Mount

Recently my external Western Digital USB drive will not mount. The unmounted disk icon shows up on the desktop when I plug in the USB drive and then when I try to mount via the GUI (right click mouse and choose "mount") it says operation failed. I am also unable to mount via command line - I get a message that says the partition is busy or already mounted. This is a production web server (SLES10-SP3) that has been running for six years with the same Western Digital USB external drive ( used to back up my web root). I am not sure if this is a sign of the external drive on its last leg or not.

I was thinking of deleting the lines referencing the Western Digital external drive in /etc/fstab and then rebooting. Is that okay to do? Thanks.

Here is my /etc/fstab

Stuttering performence raid

Hi out there, Im kinda n00b on this. But in my machine running ClearOS, I have a sata-card, and set it up as raid, raid 1 I think. So 2 x 1TB hdd's seems like 1 x 1TB but redudant to hw-failure.

But now to the problem, in linux I wasnt found the hdds as raid. So I googled and found to use mdadm to make a raid. And then I can see the raid when 'cat /proc/mdstat', output:

Code:

[yabbah ~]# cat /proc/mdstat 
 Personalities : [raid1] 
 md0 : active raid1 sdh1[1] sdg1[0]
       976759936 blocks [2/2] [UU]
       
 unused devices: <none>

On that device I have all my ripped dvd's to the kids. But when they watch them the movies (doenst matter what movie the choise) start buffering after 4 minutes, and then it stops playing completely. This start to drive me nuts.

I tried copy a iso-file from that device over my network to my computer, I saw that after about 1gb copied, it paus the copy for about 20seconds. Same after 2,3, and 4 gb. So something is completely wrong.

How can I solve this without loosing the data?

Kind regards and marry christmas

A Little help for Shell Script

CME 1003 Shell Script Assignment
Project Specification
A shell script is a script written for the shell, or command line interpreter, of an operating system. Typical operations performed by shell scripts include file manipulation, program execution, printing text etc.
Shell : In computing, a shell is a piece of software that provides an interface for users. In this project, you should prepare a Linux shell script which performs following operations:
Your script will ask user 4 options : Create, Move, Delete, Copy. The option will be applied to
Directories and/or Files which contain given name.
Examples:
Create : Reads a directory name and number from user and creates directories.
Example : directory name = student
number = 13
student1, student2, student3... student13 directories will be created by this option.
While creating each folder, script will ask user directory permissions. (permissions could
be given by number values like; 775 for rwxrwxr-x)
( NOTE: If directories exist, inform user!)
Move : Name and new location is taken from user.
Copy : Name and new location is taken from user.
Delete : Name is taken from user.
NOTE : Each operation will be logged in log.txt such as:
Example : Directory documentation_13.11.2007 is moved to upper directory
All of these options will be listed as a menu for user. At the end of each operation menu should
be shown unless user selects Exit option. The shell script should display appropriate messages
such as warning, information.
Example : If given filename does not exist, warn user.
NOTE : The wildcards should be accepted by your shell script as user input !

Please help me..

Howto Xserver dual screen setup with LCD TV?

Hello, I'm trying to configure dual screen on my slitaz linux. I have connected s-video port on graphic card (old Nvidia Geforce MX440) with AV connector (yellow cinch) on LCD TV (32" LG32LD350). I want to have cloned screen on both, pc monitor and tv. How can I achieve this?

What I tried till now:
If I try to turn on twinview in nvidia-settings, the image on TV is cloned, but image on TV is grayscale and is flickering - I didn't find any option to increase TV frequency, colors are set to 32Milion. I tried it two days ago and somehow the image was color, I don't know how to set it up again :(. So I'm sure, the cable is OK.
I got same results, when I tried to set xorg.conf in either twinview or separate screen - screen is grayscale and flickering.

I tried to change almost avery option in config file without desired result, so I would be thankfull in any ideas.

This is my xorg. conf:

Nvidia Driver Settings: Extended Display Help

Hey,
I recently bought a new Graphics Card (Nvidia GTX 570) replacing my Radeon HD 6850. However i'm having problems getting the display settings to work how i would like.

Previously i had an extended display over 2 monitors, with the main desktop (i.e. Panels on 1 screen) and the other monitor blank except for the desktop background.

I've installed latest driver (from Nvidia) and it all works fine. I configure the nvidia driver to have monitor 0 as 1920X1080 and monitor 1 as 1650x1024, right of monitor 0.

If using separate X screens i get the two screens like intended, but both monitors have the panels like a main display, but no compiz. If i enable twinview i get dual screen with compiz but again both monitors are treated as the main display (i.e. panels appear on both). If Xinerama is enabled on either of the above, i 1 big screen like i want with the panels on the main display but no compiz or desktop switcher. All settings also only give one mouse for both monitors.

Some help would be great, Xorg.config can be given if necessary.

dhcpd6 do not reply the query

Hi All,

I'm trying to setup a dhcpv6 server in my office with CentOS 6.1 + dhcpd6, below was the dhcpd6.conf file.

Code:

default-lease-time 600;
 max-lease-time 7200;
 log-facility local7;
 
 authoritative;
 
 subnet6 2222:1111:107a:7::/64 {
         range6 2222:1111:107a:7::500 2222:1111:107a:7::1000;
 }
 
 allow leasequery;

after i'm start the dhcpd6 service with the command:

Code:

/usr/sbin/dhcpd -6 -f -cf /etc/dhcp/dhcpd6.conf eth2

The service are successfully start with the info that show as below:

Code:

 Sending on   Socket/5/eth2/2222:1111:107a:7::/64

I'm trying to use a Win 7 machine and another CentOS 6.1 machine to get IPv6 address from the DHCPv6 server that I've setup but it fail to get any IPv6 address. By using wireshark to capture the packet, I only see the client try to send a DHCPv6 Solicitation to all DHCPv6 multicast group but DHCPv6 server never reply to the solicitation, anyone encounter similar issues? I've disabling the ip6tables to ensure is not firewall issues. Hope you guys can advise.

Cheers,

Tightvnc/RDC on Mint 12

I installed Tightvnc, and in Synaptic it shows to be installed, but I can't figure out how to run it. I can't locate it anywhere under Menu > Applications area.

Secondly I installed Vinagre, and now show the Remote Desktop Viewer under Applications > Internet, but there is no options to configure as a host.

I was able to run Tightvnc on my Win7 machine, and control from the Mint's RDC viewer, however I am trying to get it the other way around where Mint is host, controlled from Win7.

Thanks for any help...

Posix message queue help

Hi,

I am developing an API which will communicate with a daemon.
I am using POSIX message queues.

The API functions will send a message requesting data to the daemons message queue. The response from the daemon will be sent to another message queue which will be read by the api calling function and the then the api sends a response back.

My problem is that how to read the messages coming from the daemon. Here is example

api function A
{

send message to message daemon
poll message queue

}

api function B
{

send message to message daemon
poll message queue

}

Can the polling of the message queue just waiting for a certain message? api function a is waiting for its response and api function b is waiting for its response but it one function reads all the data then its a problem. What do you think is the best way to handle this?

thanks for your time

Recommendation About Backtrack

Well, I just currenlty planning to download Backtrack 5 R1 but I stuck with something.

First, there's two favor as you guys know, Gnome and KDE. Currently I am using Fedora with Gnome, and it works perfectly for me. But when I go through some Backtrack Tutorials or something, most of them is using KDE. The interface looks perfect but recently when I was using Fedora with KDE, I got a lot of problems in web browsing:
1. The built in browser Konqueror, wasn't too happy with the flash plugin.
2. Then I installed the mozilla, the 'scim' chinese input not working.
So the conclusion is, if I need flash, I need to open the mozilla, then if I need to type chinese, i need Konqueror. It just wasting time to use 2 browser at once. lol

Then, I am thinking about using Backtrack as my main os, even the ONLY OS, but I worry it's difficult to have other application like Mozilla, Chinese Input, even VLC player. If I'm using Fedora, I can just install them with 'yum', but I don't think Backtrack have the same mehtod.

Please someone give some suggestion or solution about these.
Thanks =)

Squeeze Dual Root With Single Userspace

I would like to run Debian with multiple roots and share the same /usr directory but am unsure if this is asking for trouble. My ideal setup and reasons are below:

/dev/sda1 100MB /boot
/dev/sda3 4096MB swap
/dev/sda2 400GB LVM

LVM broken up as:
Root_Stable 75GB
Root_Testing 75GB
USR 50GB
Home 200GB

I have my stable 2.6.32-5-686 default kernel for backup with a grub entry to boot the system with either Root_Stable or Root_Testing. I also a working 3.1.5 kernel that can boot with either root.

The whole point of this is I do a lot of modifications and mucking about with the system in general. As I only have one computer so my Root_Stable is a standard netinst install with no modifications while the Root_Testing is a custom debootstrap with no SELinux support. As things become stable I shift the mods into the Root_Stable pretty much the same way Debian has its releases set up.

The main thing I am worried about is how to share the /usr directory. I want access to my applications regardless to the root I am using but I do not know of the many interrelations that are going on in the background and if I ran two roots would apps freak out and start mutilating my data? Wine is a good example, I built from source and installed in /usr/share/wine and it worked great. After a few boots around the different roots now wine does not even load when run from the command line. Is thing an expected side effect of how I want to do things? and if so should I just run two user directories after all?

Thanks!!

Help me pick a distro!

So I have been looking for another distro to try but there are so many. I am currently on Mint 11 but have only tried Ubuntu. So I definitely would like to try a none Debian OS, to see the other side of the fence. But I also dont want to try something as intense as Arch Linux(from what I herd). I have decided between OpenSUSE and Fedora. Could some explain the highlights and weakness of both and Ill make my decision.

Ubuntu BackTrack5 "Found following drivers in Kernel: No such file..."

Hello Community
I'm German and I hope you can understand my English :)
I have downloaded and installed BackTrack 5. It is based on Ubuntu.
After installing and configuring I have written in the Command Line:
airdriver-ng kernel
that should list all in-kernel driver for wlan cards. I know from another list that the drivers for my wlan card are in this list but it only displayed errors:

Code:

Found following stacks in the Kernel:
 grep: /lib/modules/2.6.39.4/build/.config: No such file or directory
 grep: /lib/modules/2.6.39.4/build/.config: No such file or directory
 grep: /lib/modules/2.6.39.4/build/.config: No such file or directory
 
 Found following drivers in the Kernel:
 grep: /lib/modules/2.6.39.4/build/.config: No such file or directory
 grep: /lib/modules/2.6.39.4/build/.config: No such file or directory
 .
 .
 .

I'm now sitting under my desk because my lan cable is too short and hope to install driver from "airdriver-ng" but I cant.
I hope somebody of you can help me.

With friendly Greetings Raecher2503

P.S.: Happy Christmas :D
