In our server the symbolic link to libc.so.6 has been deleted. Now none of the binaries in the system work. To fix this, I tried:
libc.so.6
/bin/ln -s /li
Try:
LD_PRELOAD=/lib/libc-2.17.so ln -s /lib/libc-2.17.so /lib/libc.so.6
Note: The actual version depends on your library.
Boot using a live cd like Knoppix or whatever and fix the missing link after mounting the disk with the "broken" system out of the running live system.
