hp9000system Container SSHD not answering

I've just created an hp9000system container from an 11.11 PARSC image.

The IP Addresses look OK.

I can ping the secondary. and from the container I can ping the gatway. and I can ssh to the host server from the container.
Oustide systems can ping the secondary IP.

ssh doesn't connect from the host system or outside systems to the container.(srp_su works fine)

It tries. It gives me the key update message and then times out.

I've tried to find documentation on this without success.

Have you referred the "HP 9000 Containers Admin guide"? if not please use this link to get it : HP 9000 Containers Admin Guide

Chpater 12: HP 9000 Containers Troubleshooting ->Triaging HP 9000 container access issues

 

After following this if it does not resolve, please take tusc logs on sshd process.

Re: hp9000system Container SSHD not answering

Hi
I had that last week, and fixed it by altering the file /etc/opt/ssh/etc/sshd.config; setting "KerberosAuthentication no" and "UsePAM yes", then restarting SSH with "/sbin/inet.d secsh stop" and "start".
What the implications are for system security I'm not sure, but it fixed it for me!
