telnet problems

Ignite_2 — Tue, 05 Jan 2010 09:16:56 GMT

Hello experts,

I have a problem with telnet connection to hp-ux 11.23. It's a VM guest, running on HP-UX 11.31. Telnet service is allowed and listening, but when trying to establish session I get following:

#telnet localhost
Trying...
Connected to localhost.
Escape character is '^]'.
Local flow control off
Connection closed by foreign host.

I've tried to connect from VM host as well as from VM guest. There is still same result. Do you have any idea?

Thanks in advance

have you tried to login to VMGuest from
HPVMHOST console ?

Did you try "hpvmconsole -P guest_name" to start a console session on the guest?

Hello Ignite,

It might be because of some security feature.

Please post following outputs from the affected machine:

1# telnet 0
2# ps -ef | grep -i telnet

Check following files:

3# more /etc/services | grep -i telnet
4# more /etc/hosts.deny | grep -v ^#
5# more /var/adm/inetd.sec | grep -v ^#
6 Was telnet working before?

Thank you all for quick support. The problem was, that IP address of interface to be used for telnet wasn't in /var/adm/inetd.sec.

Thanks a lot :)
