The following is a sanitized output from a connection problem I've
encountered over the last couple of days. I'm not sure where this
issue came from, is it worked Monday, but not last night.

This is from a Fedora 9 host to many versions of Netscreen ScreenOS
devices, as described in the debug.

Can anybody help me find out what's going on from the below?

Thanks,

Jonathan
