HPUX 11.11 PARISC - inetd spawning many telnetd processes

[Cara Tock]

Hello.

HPUX 11.11 PARISC Patches, Dec 2007

For some reason, inetd is spawning a telnetd session every time I connect via terminal emulation software (Reflections).

Once I do get connected to the server, I type a couple of commands and then get disconnected from my telnet session. I log in again and then get disconnected in a minute or two.

It seems that each user session for the user - root never disconnects/cleans up (normally I don't use root to log in directly - wanted to see behavior of logging in as root as opposed to non-root user)

Suspecting an issue with inetd, I went to the console, did an "inetd -k" and then "inetd -l"
so I could get more logging for troubleshooting this issue.

Has anyone heard of an issue with inetd/telnetd
that requires a patch/system tuning?

Please advise.

Yes, that is completely normal.

>>"inetd -l" so I could get more logging for troubleshooting this issue.

What have you found with the logging turned on?

I would look for any inetd cumulative patches.

Shalom,

For some reason, inetd is spawning a telnetd session every time I connect via terminal emulation software (Reflections).

Reflections uses telnet to connect and make sessions.

This is perfectly normal.

Hi,

That is the behaviour of inetd daemon. It is the master daemon which is responding to all ARPA/Berkley service requests like ftp/rcp/remsh/telnet etc.

For each request it will spawn a new process(telnetd/ftpd/rlogind..)

For instance if five telnet requests it will spwan five telnetd process. It is applicable to other services also like ftp, rlogin, etc..
