ssh to hpux hangup

[haux]

When I connect to an HPUX server, the session hungup after some minutes.

Impossible to reconnect.


User1@Linux-PC:~$ ssh -vvvv -l User1 HPUX-1
OpenSSH_4.3p2 Debian-9, OpenSSL 0.9.8c 05 Sep 2006
debug1: Reading configuration data /etc/ssh/ssh_config

debug1: connect to address 10.10.5.20 port 22: Connection timed out
ssh: connect to host HPUX-1 port 22: Connection timed out



On the HPUX-1's file : /var/adm/syslog/syslog.log I can read this :

....
Apr 27 11:34:53 HPUX-1 sshd[19917]: warning: can\'t get client address: Connection reset by peer
Apr 27 11:34:53 HPUX-1 sshd[19917]: Could not write ident string to 0.0.0.0

Apr 27 11:34:41 HPUX-1 sshd[19917]: Could not write ident string to 0.0.0.0
....

I verify on the Linux that i get always a valid IP


User1@Linux-PC:~# ifconfig

On the HPUX-1 I get this version of sshd:

root@HPUX-1:/home/User1 >#swlist | grep -i secur
T1471AA A.04.40.006 HP-UX Secure Shell




Any idea where is the problem ?!

Thanks

Try to make sure the HP box can resolve your PC correctly.

On the HPUX, try to add this line in /etc/hosts:

10.10.11.127 Linux-PC.yourdomain.com Linux-PC

And give it another shot.

Cheers,
