/lib/libc.so.6 accidently removed


Hi,
I accidently removed /lib/libc.so.6 running Red Hat 5 Enterprise edition.
I think this /lib/libc.so.6 was a symbolic link to /usr/lib/libc.so

I am unable to execute any of the commands
[root@netappsim lib]# ls -ltr libc.so.6
ls: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

Please help me as how to revert the sym link /lib/libc.so.6

Thanks,
Raghu

Welcome to LQ.

Code:
ls -l /usr/lib/libc.*
-rw-r--r-- 1 root root 2811674 Jan 21  2009 /usr/lib/libc.a
-rw-r--r-- 1 root root     238 Jan 21  2009 /usr/lib/libc.so

 ls -l /lib/libc.*
lrwxrwxrwx 1 root root 11 Aug  7 18:58 /lib/libc.so.6 -> libc-2.5.so
If you can use the command line :
1) cd /lib/
2) su
3) ln -s libc-2.5.so libc.so.6

Else you will have to shut down the computer.
And use a live Linux cd to get to a command line,
and ' cd ' into /lib/ , to do the ' ln ' command.
.....

If the above doesn't work, before restrting the box, try:
Code:
/lib/ld-linux.so.2 --library-path /lib /bin/ln -s /lib/libc-2.5.so /lib/libc.so.6
It's worked in the past in a similar situation with the error messages you got.

Smile Thanks

Thanks for all the replies.
The ln command was also displaying the same error messages since ln seems to be using/linked to libc.so.6

I had installed Redhat Linux as a Guest OS using Vmware running Windows as host.
Fortunately I had the recent backup of the entire the virtual machine and so was able to revert to the earlier state.

Unfortunately, i didnt try executing /lib/ld-linux.so.2 --library-path /lib /bin/ln -s /lib/libc-2.5.so /lib/libc.so.6
as I had already restarted the system.

I was surprised I couldn't find an answer to the "removed libc symlink" problem other than "use a live CD" (which I couldn't do, as I did this on a server on the other side of the planet). I resolved the issue by using a statically linked version of "ln" that was already in the server's /sbin.

E.g., this restored it for my configuration:
/sbin/sln /lib64/libc-2.5.so /lib64/libc.so.6

The statically linked ln doesn't need the dynamic libc.

Thank you so much for this easy solution for i am using someone else's VMware
and does not have a Live CD to recover the missing libc.so.6. I was really
sweating when i found `ls` was not working. Your post really saves my day,
thanks again.
