Re: unable to telnet

Check if you could login to the server via console.

Reboot will resolve the issue.

Re: unable to telnet

For what reason are you trying to umount /opt
Is it increasing the /opt FS.
If yes, then you need to login to Single user mode to increase the FS, in case Online JFS(licensed software) is not installed,.

Re: unable to telnet

Do not attempt to unmount essential filesystems without first making sure you have console access to the system.

Do not use "fuser -k" without first checking what you're about to kill.

Your fuser -k command has probably killed several system processes, including inetd. If inetd is not running, the system cannot respond to telnet connections.

You must login on the system console to solve the problem. Usually the easiest way to solve it is to reboot. Of course, *if* you know which services should be running in your system, you can just restart them.

Based on a quick check on a PA-RISC 11.23 system, possible things to restart are at least:
- ipfilter and sshd (if installed)
- all NFS-related services
- sendmail
- inetd
- snmpd and its agents
- WBEM cimserver
- DCE rpcd
- System Management Homepage (smhstartd)

Re: unable to telnet

Hi John,

nothing to do with the technical issue in the server you might be facing, but a closed thread can always be reopened by the author if the author wishes.

at the bottom of the discussion you can click the "Reopen Thread>>" button.

just to tell if you thought a closed thread can't be reopened!
