Is your inetd process running ?

ps -ef|grep inetd

If not you can start from the console with;
/sbin/init.d/inetd start

Hi

Check inetd.conf for :-

telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b /etc/t
nlogin

IF ok then :-

inetd -c to re-read

Then check that telnetd is running.

I am getting an error from the inet.d start i.e

Bad System Call (coredump)
Exit Code:140

Sounds like a resource problem which is preventing inetd from running. Youre going to have to reboot to fix it.

When it comes back up youre going to need to monitor it closely to see what resource ran out (memory, swap, disk) to stop the problem recurring.

I rebooted the Box and the Network Services fail to start from the boot process

Re: Unable to telnet remote server

it depends on what the telnetting system is getting back as reply , can you give more information , is the connection happening but halting , are you getting permission denied messages , no such service or any other error message , is syslog on the 11.0 machine containing any message on telnetd???

this could be any of multiple problem , either you dont have telnetd in inetd.conf or , it is secirted in inetd.sec , you could have not enough PTY's or not enough users (maxusers) on the system e.g. we need more info here

Re: Unable to telnet remote server

Hi,
Do a what on /usr/sbin/inetd file. I'v seen before that executables for some reasons has become empty (null length) or simpely being overwritten by another file.
