I've been working with out servers for the past several years. We have a mix of OS. Fedora, Ubuntu, RHEL, etc. I've accidentally trashed the libc.so.6 link and now nothing but shell commands work.
I tried to echo "/lib/libc-2.10.2.so into the /etc/sestatus.conf file, but that didn't have any affect. Does anyone know where the search path is maintained besides PATH so I can try to point the apps to the /lib/libc-2.10.2.so file? I have a bunch of SVN repos on this server and right now, no one has access.

I want to supply the shared libs along with my program rather than using the target system's due to version differences:
ldd says my program uses these shared libs:
I have successfully linked ld-xxx.so by compiling like this:
But I have not managed to successfuly link libc-xxx.so.

I want to create a Live USB ..I have the ISO image in the hard disk
Where Sdb is my USB
The copy operation is okay...It says no of records in / out and gives the statistics
But when I boot the system , getting the error:
Boot :
In some cases , the USB itself is not recognized by BIOS at boot..
My BIOS supports boot from USB ..I have Boot order 1. CD/DVD 2. USB 3. HDD
Also what is the filesystem to be adopted for dd?
I usually format using FAT or FAT 32
1.mkfs.vfat /dev/sdb -I (or)
2.mkdosfs /dev/sdb (or)
3.mkdosfs -F 32 /dev/sdb
What is the correct way of partitioning USB drive? - FAT or FAT 32....Most Live USB creators (unetbootin/LiLi Live/Usb Creator) recognize only FAT32...
I dont want a Linux filesystem (ext2,ext3 or 4or reiserfs)for my USB as it is not portable across many systems as MS OSes do not read them..Also I had little success in booting a USB when I partitioned it using ext2..I read somewhere that ext2 will not reduce the life of the USB drive compared to other fs.

We have three production websites running on RHEL 3 AS running tomcat 5. After a reboot last night Tomcat will not start and has the following in the catalina.out log:
Mar 20, 2011 4:09:31 PM org.apache.commons.digester.Digester startElement
SEVERE: Begin event threw error
java.lang.NoClassDefFoundError: org/apache/naming/resources/ProxyDirContext
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)
at java.lang.Class.getConstructor0(Class.java:2699)
at java.lang.Class.newInstance0(Class.java:326)
at java.lang.Class.newInstance(Class.java:308) .....
I have spoken with our Java Developers and they seem to think it is something up between httpd and tomcat at an OS level. Since Tomcat is not starting and giving an error that it is all ready running, I think you have a stale lock file. Look for the file /var/run/tomcat5.pid and cat or less it to see what the PID number is. If it matches the error, then delete the file and try to start Tomcat again. It should start this time.
Most common problem with Tomcat5. Try following :
1) Search PID in /tmp, if found delete it or else stop your tomcat.
2) Undeploy your application
3) Check out this link [URL] to know what causing tomcat to generate this error.
If none of them work then check your application configuration settings. [URL]. When I do start tomcat it appears to start:
[root@RPSI-2 san00]# service tomcat5 start
Starting tomcat5: Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
Using JAVA_HOME: /usr/java/jdk1.6.0
[root@RPSI-2 san00]#
But then I try to find if it is running via ps -ef | grep tomcat5, I only receive my query. I perform the same query on Java and it also only returns my query.

I am trying to create a server on my laptop. I have a windows 7 OS. I have downloaded Apache HTTP Server, MySQL Server and PHP. My Apache seems to be working well at one point i.e., when I use the http://localhost "It Works" does show in the browser. When I attempt to sign on the MySQL Server with my password the command prompt shuts off so quick I can't even read what the window says. The MySQL server seems to be running in the task manager under mysqld.exe.
End goal: have mysql running and adn communicating with php on apache.

Every time I boot up ubuntu I usually open 3 terminal windows and ssh into the same server. I would like to either click a shortcut, or run a single terminal command that will do the equivalent.
I came across the "gnome-terminal" command, but I was unable to get it to trigger an ssh command.
Ideally I would like to have a script that I pass in the number of windows I want to open and the server I would like to ssh into for each window.

I am using Ubuntu 10.04. In the summer a few months back, I managed to get my ancient HP Laserjet 6L printer working via a wired D-Link-DPR 1061 print server and Netgear network switch. This was even though it was not on the print server's compatibility list. A couple of months later it stopped printing and I have not been able to get it going again since.
The print server has one parallel port (used by the 6L) and a couple of USB ports which I don't use.
I have been going through the Ubuntu add printer wizard. The print server can connect via an IP address. I am using its device URI: lpd://ip address/dlk-portname
I have tried all 5 HP laserjet 6L drivers that come with Ubuntu without success. I have the foomatic/ljet4 [en] currently selected. When I try to print a test page nothing is printed and when I do a print self test I get this message:
CUPS SERVER ERROR There was an error during the CUPS operation: 'client-error-document-format-not-supported'.
By, the way I also have a Windows 7 PC and managed to get the 6L working with same print server using the XP drivers, but every so often it stops working. A reinstall gets it going again.

There are basically two main limitations with hard links:
Hard links normally require that the link and the file reside in the same file system. Only the superuser can create a hard link to a directory.
Thus, symbolic links were introduced to get around the limitations of hard links. So, the question is, are hard links still needed? Might there be situation where they are more useful?

I have heard that creating hard link to a directory is not possible however when reading the man page of "ln" the "-d/-f" option says hard link directories ( super-user only). Thus this mean the super user i.e root can create hard link to directory and not a normal user , If yes then you . Even on specifying the above options I get a operation not permitted for a super user.

I have installed gcc-3.3 & g++-3.3 in ubuntu 9.04. Now I want to change the default compiler as gcc-3.3/g++-3.3. After creating links to newly installed gcc/g++, gcc works fine but g++ doesn't work.
When I give "$which gcc" or "$gcc --version" it works fine, but when I give "$which g++" it gives nothing and also "$g++ --version" it gives an error "the program 'g++' can be found in the following packages: * g++..." When I installed gcc I gave the command "$configure --perfix=/opt/gcc33 --program-suffix=33 --enable-languages=c,c++" . When I give "$which g++33" and "$g++33 --version", work fine.
I tried following:
$export CXX=g++33
$sudo ln -s g++-3.3 g++
Nothing happens. I am very new in Linux and I need to install ns2.1a9b in gcc-3.3.

I have a Java program (minecraft server) that needs to be run from the command line. The code is:
Code:
java -Xmx512M -Xms512M -jar minecraft_server.jar nogui
To make life easy (i've got the java file in a folder on the desktop) I want to have a shortcut (or similar) sitting on the desktop. I've tried
Code:
ln 'java -Xmx512M -Xms512M -jar minecraft_server.jar nogui' ./../minesraftserver
with single and double quotes but my unix command line skills are pretty basic and this is obviously incorrect.

I have a bit of a problem that I don't understand and would like some help please - I will try and explain the best way I can. I installed Ubuntu using the WUBI installer and so I can access my Windows partition in /host. Using Wine I can run World of Warcraft by going to /host/Program Files/World of Warcraft/WoW.exe But I would like to create a link on my desktop to that file so I do not have to keep going to that path everytime.
The Problem - when I click make link and drag it to my desktop I double click the file (expecting it to just act like a windows shorcut) but it doesn't - it creates some of the files that are in the world of warcraft folder on the desktop and then fails to open with message: Failed to open archive dataart etc...its like it is creating a copy of files on my desktop of what is already in the WoW folder.

ln /home/user/file
within the new directory i am trying to link from. I am using centos 5.4.

I have an external hard drive mounted at /media/exthdd/ On that hard drive I have folders: Music, Pictures, Videos, etc. Can I make symbolic links to /media/exthdd/Music/ to say the root directory /_ ? the directory /_ is empty I just want a quick method of typing to get me there much like [cd ~] gets me to my home/username folder. I have my music organized by Artist/Year-Album/Track.Title.mp3 I want to be able to "cd /_" then "ls" and see all Artist folders.

CentOS 5.2 64bit 2.6.18-92.el5xen. Use rsync with --link-dest for nightly backups, works well. Was recently asked to start weekly backups to an external drive for off-site storage. The regular syncing works but hard linking seems to be ignored. So the backup is long with no space saving advantage. Here is an example of the command being run:
rsync --stats -axzvl --numeric-ids --delete --link-dest=/mnt/DISASTERBACKUPS/austinBackups/backups/2009-08-21 /AUSTINBACKUPS/backups/2009-08-24 /mnt/DISASTERBACKUPS/austinBackups/backups/

I would like to build a NAS from PC (D510MO) running Debian. I have two HDDs (one 3.5 1T and one 2.5 500G).
On 3.5 HDD I have already two partitions 100M+40G dedicated for Win7-64. Now, I want to install Debian (second OS) on this PC and to have some kind of soft RAID or disk mirror of 500G space. I am planning to create a third partition on 3.5 HDD of 500G (identical as 2.5 HDD size) in order to have a mirror 500G space.
Please send my some suggestions on where I have to install Debian; on 500G 2.5HDD or 500G 3.5HDD!Will Debian boot from both HDDs 3.5 or 2.5 after I create the mirror? What Linux soft I have to use for mirroring (mdadm)?
