Topic: Can't access console anymore

[guestHH]

Hi,

I've got a strange thing goin on here. I can't access the console anymore.
Don't know why but if I try to access as root it simply returns: access denied.

During a reboot a came accross this one:
su: PAM unable to dlopen(/lib/security/pam_xauth.so)
Jun 26 08:25:01 star-support su: PAM [dlerror: /lib/security/pam_xauth.so: cannot open shared object file: Input/output error]
Jun 26 08:25:01 star-support su: PAM adding faulty module: /lib/security/pam_xauth.so


The messages log file tells me (using putty to gain access):

sshd[2257]: PAM unable to dlopen(/lib/security/pam_unix.so)
Jun 26 08:28:08 star-support sshd[2257]: PAM [dlerror: /lib/security/pam_unix.so: cannot open shared object file: Input/output error]
Jun 26 08:28:08 star-support sshd[2257]: PAM adding faulty module: /lib/security/pam_unix.so
Jun 26 08:28:08 star-support sshd[2257]: Failed password for ROOT from 192.168.1.77 port 3119

Anybody any idea?

/lib/security/pam_unix.so

Do you have that file?  If so, I wonder if you have a bad sector on the drive that is preventing access to that file...

You may want to fsck.ext2 that disk.

Thanks Nathan.

It is indeed a HD issue. I've run fsck.ext2, even twice to make sure.
But still can't access the console. Same issue.

I thinks I have to copy new pam* files to my server. But how if can not access it...

Is networking active (smb share) in esmith single mode?

Run (from a boot disk or something):

fsck.ext2 -p -y -c -f

[guestHH]

did that too (didn't know it would take up to a couple of hours

Same result:

Bummer. I think the only thing left is to copy new pam_x files to overwrite the existing ones.

Everythng else works fine, just logging in to the console...

Have you tried to access the console via its IP address?

If that works, then add a new network from the console and remove it again. Now does your console access work correctly?
