Telnet issue E5500/V480

Our old E5500 was just turned off (planned Smilie ) and the application was moved to a V480.

Now if I login to the V480 and try to sudo to root my connection hangs, and I can not telnet to the E5500 after it was powered on again. I get "connection refused". Telnet to this machine was available.

I have found, in vfstab on the V480, a hard mount to the E5500 server:

#E5500:/admin/vault_extra - /vault_extra nfs 2
yes hard

I can not remove that mount because if I try to sudo, it hangs...

To complicate this, I can not find a video card at all on the 5500, so I can't see what is going on, nor do I see a keyboard slot either.

Has anyone seen this problem? If I am missing the video card on the machine, where is it normally?

Thanks.

1. try to use a serial connection to your 480 (you should be able to login as root on console)
2. in "/etc/default/login" look for:

# If CONSOLE is set, root can only login on that device.
# Comment this line out to allow remote login by root.
#
CONSOLE=/dev/console

3. better use ssh, not telnet!

Doubt there is a NFS mount from your E5500 system since there is a "#" in front of the line which makes it comment.

If you use the "df" command, does "/vault/extra" show up in the list?

If not, there is no NFS mount.

The nfs mount was there, my bad on the typo (no #).

The problem has been fixed however. I was doing an "su -" as opposed to just an su. When I su'd in, I was able to change the vfstab and unmount the hard NFS mount (umount -f /mount_point).

Thanks to all for the answers.

And I know, ssh, not telnet. This was here before me and was destined for removal so I spent very little time on it.

When you do a "su -" instead of a "su", all the login scripts (like .profile) of "root" are executed.

So depending on whether you want to have "root" access with your own environment settings or those of "root" you either use "su" or "su -".

Apparently there is something bad in the login scripts for root, otherwise you wouldn't get stucked.
