Nelson,

If the SSH session drops due to inactivity you cound try the clientaliveinterval and serveraliveinterval in sshd_config. See sectiion 2.12 of the openssh FAQ. There are probably other ways to do this as well.

In the output below, it appears your client is trying to connect to bbd on the local host via the loopback address (127.0.0.1). Are you sure you have the BBDISP variable in your hobbitclient.cfg file set correctly? It should be pointing to the xymon server, not the loopback address.

Hi,

I would like to report that I manage to resolve this problem.

The problem was that the tunnel timed out and hanged.

I solved it by changing the report time in client-local.cfg on the clients from 5m to 1m .

Maybe to 3m would work as well but this one is working so I'm not messing with it right now.

I would like to thank everyone for the help and support.

Regards
