So it's throwing you out without even asking for a password? Looks suspiciously as though /etc/passwd has gone missing.

How recently have you logged in? If it was recent, what's changed? Do you have an ignite backup?

OUCH!

Do you know of anyone currently logged in? If so try to get to a shell prompt and su up to root. Can you login as another user?

If not, then a hard reboot is necessary and then go into single user mode and fix the problem-> corrupted /etc/passwd file, /etc/securetty is wrong, account is disabled, ...

Looks like, there is a problem with /etc/passwd file. Can you login as normal user?? Check /etc/passwd file and it's perms.

If nothing works, boot into single user mode and check passwd file.

Hi All,

Thanks for prompt reply.
1)Even I am not able to login as normal user.
2)Have hard booted the machine but it doesn't work.
3) Now have booted machine thru CDROM & able to mount the /root.
4) I have already tried coping /etc/passwd file of cdrom but it does not work.
5) By chroot I am able to mount my original / partion & changed the root password with command passwd root . But this also does not worked.
6) Note : I am not able to locate the /etc/securetty file. It's not there in /etc.

Please let me know what could be the problem.

Regards

Walter

can you check size / date on /usr/bin/login ?
if it's corrupted, you can copy it from another system.

Not having an /etc/securetty is a good thing (for now).

Did you recently make this machine a trusted machine??

What changes have you made to this machine recently??

Do you have an ignite backup (make_tape_recovery or make_net_recovery) of this system?

has login of root ever worked? For how long?

Walter,

Check the permissions of the /usr and / directories.

# ls -lad /usr
dr-xr-xr-x 24 bin bin 1024 Jun 23 2004 /usr
# ls -lad /
drwxr-xr-x 19 root root 1024 Mar 24 14:34 /
