Telnet issue

Gabriel_23 — Wed, 25 Jun 2003 17:57:59 GMT

I am receiving the following message when trying to telnet to a specific server:

"Connection closed by foreign host."

I do receive a login prompt first, but after entering my login id, I receive the message. Not sure what is causing this problem. Please help...

Hi

What emulation are you using?

Try vt100 or wyse60.

Hi!

Does the account you are using exist in the other server?

Regards,

Dario

Emulation is vt100 and account exists on both servers.

Hi,

This could be due to several reasons. Do ftp, rlogin etc., work?. If so, try ftp and get the syslog.log file onto the localsystem and look at the errors.

Try this. From the console, run the commands

'insf -d tels'
'insf -d telm'

and then try telnet again.

Hi

Is a HP server?

What devices are in the path?

Can you telnet to it from another machine?

Is your account set up on the remote server?

Server is HP. I can access server via ssh. I can also ftp to this server. Only telnet is giving problem. I have an account defined on the remote server also. Tried using the insf commands, but telnet is still having problems.
Thanks to everybody for all the help so far.

Hi

Can you stop and restart telnetd on the remote system?

Hi Gabriel,

First logon to the box using ssh. Do a 'tail -f /var/adm/syslog/syslog.log'.

Then telnet to the box with another session and observe what error you get there in syslog.log. Post the error if you are unable to determine the solution.

I only noticed the telnetd process once I issued the telnet command to the server I need telnet access for. I killed the process on the problem server and re-issued the telnet command, but problem still exist...

Gabriel

Are you saying that telnetd only appears when you try to login?

Paula

Performed real time tail on syslog file and the only message that may be linked to the problem is:

"login: load_modules: no module present"

Not sure if this is related or not.

Paula,

You are correct. I just issued a grep for the telnetd process on the server and there was no telnetd process running.

Hi

set telnetd in inetd.conf then:-

inetd -c to re-read its config.

Sri,

That's all I could find in syslog.

OK. You can get more details by running "inetd -b".

Run it. telnet to the box again and post the error.
