[hobbit] Clients loosing connection trough ssh-tunnels

[Nelson Amaral]

Hi, 

Thanks for the help so far, you guys are great. 

I do get clients reporting and connecting to the server, but after a period, let's say 30 minutes they stop reporting and the alerts go purple. 

I will try tomorrow to set the tcpkeepalive in the sshd_config to yes and see if this is the problem. 

I have a funny feeling it is the tunnel that times out. 

Another funny thing though , the ssh-tunnels column stays green. 

the columns for cpu, memory,etc go purple. 

Regards 

Nelson Amaral

That might be the tunnel IP:port of the remote BB server. What happens when you try to telnet to the server directly, from the client? (To determine if the tunnel really is up).

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.
