Back story: Was trying to install lsync on SRV-2 from source, since srv doesn't have internet access(i tried proxy but nothing either). Lsyncd install was successfull but when I tried to run a lsyncd command i would get "dependency libc6" or something like that. So downloaded and installed libc6-2.11.3-4. Then this when i try to ssh to it:

Now I believe ssh works but I cannot remote console in (box located at remote location) because it gives me the same results. I've researched a lot that i have to update the box, or restart ssh service etc. But cant seem to figure it out. Im certain i did something stupid, so any light on what could have gone wrong would be very appreciated. Would reboot the SRV box be the final option? Any other info you need from me please let me know.
Thank you for your time.

The glibc is one of the most essential parts of a Linux system. Updating it without updating the rest of the OS is almost always a bad idea and can lead to all kinds of weird and unexpected behavior. I recommend to play back your backup and upgrade the whole system, if you need a newer glibc. If this is a production machine you should of course test the changes that will occur on a test system first.

Thanks for the reply. Will look into the GLIBc library and what exactly it does. Unfortunately I was not able to resolve the issue (boxes were replaced). Will be more careful next time. Thanks for the reply tobysgd.
