SSH session only works for 10-30 seconds?

I'm trying to get the java/SSH functionality working and I'm running into a weird issue. The applet launches, connects to the SSH server, you log in, and for about 10 - 30 seconds everything works just fine. Then, without any obvious trigger, the connection freezes, and eventually there's a "connection closed..." message. There's no error message in the log, just the connected and connection closed messages.

Has anyone seen this before? I'm using R7.0 (hey, it's a test environment...)

A TCP trace on the backend server should give us a hint on who initiated the close connection process, that will help in determining where to troubleshoot further.

While the SSH session freezes do you also see the SSL (web page) session frozen?

Need to determine if this is just with the SSH session between the client and the backend server or if its the entire SSL-VPN session that has a problem.

Nope, just the SSH applet. To clarify, the connection closed error comes from within the applet. The rest of the SSL session continues to work just fine.

Re: SSH session only works for 10-30 seconds?

User error, as usual. Packet capture clued us in on random RST flags, which clued us in the fact that someone had reused one of the test-IVE's VLAN IPs, and the duplicate host would, whenever it won the ARP contest, reset the connections. Lesson on documenting setups, even in lab environments. :-) Thanks for the help!
