Hi,

Are you trying to login directly to the console or is it remote login? Are you a normal user or root?

Hi,

Is it a production server?
Have you tried single user mode?
If you can try to boot in rescue mode then can you check if you find the below command:

#/sbin/getty

if this command is not found than check for the util-linux package as it provides getty.

Chhaya,

Yes, this is a dom-0 host server for XEN virtual machines production server.

Hi,

If we would have been logged in to any terminal we could have checked the /etc/inittab file, if the getty service running on all the runlevels. And also checked for the package and the command.

As of now I am not able to think of any other choice.

Hi,

some random ideas :
- if PermitRootLogin is set to "yes", you can still try to scp or sftp /bin/bash from another Debian server (versions must be the same)
- try using another shell by specifying it on the command line, for example, I would try 'ssh root@crashedserver.mydomain.com /bin/sh' or 'ssh -t root@crashedserver.mydomain.com /bin/sh'; I used /bin/sh but you can try /bin/csh ou /bin/tcsh depending on what command interpretor is installed on your system and which one you feel comfortable with.

Hope this helps !

Nils
