SUMMARY ... Bizarre response to login attempt ...

Hi, all.



Thanks to the people who have responded so promptly so far (John S, Musa
W, and Adam L).



The system was physically remote, so I used a terminal concentrator to
get to the console - luckily, I was logged in there as root so I still
had access - whew!



Turned out the problem was a disk I/O error, so the OS had dismounted
/var for some reason ... so no access to /var/adm at all!



A shutdown, followed by an ALOM power-cycle and a reboot has cleared the
issue ... /var is now available. I will watch the system to make sure
that the disk I/O problem does not recur!



Of course, one issue still remains open: if I had not been logged into
the console, I think I would not have been able to do a graceful
shutdown - unless there is some way to log in on the console without the
presence of these files(?). That would have meant a remote power-cycle
using the ALOM console without doing a graceful shutdown!



Thanks again,



Z

Hi, all.



I have a remote system that is responding to telnet login requests with
the following error:



# telnet XXXXXX

Trying X.X.X.X...

Connected to XXXXXX.

Escape character is '^]'.

login: root

Password:

No utmpx entry. You must exec "login" from the lowest level "shell".

Connection to XXXXXX closed by foreign host.

#



And to rlogin and rsh attempts as follows:



# rlogin XXXXXX

No utmpx entry. You must exec "login" from the lowest level "shell".

Connection to XXXXXX closed.



Given these responses, how can I get into the system to figure out what
is going on? The system has been working quite normally till now ... L
