I'd start by looking for messages in /var/log/authlog on the OpenBSD machine, and if possible running with ssh -v or -vv (I forget how many you can usefully put in, or if the Cisco boxes even use the same options) to get more detail on what happens. My hunch is that you will be looking at resolving a gap in ciphers offered as available at either end. Newer ssh versions have incrementally dropped or disabled by default the unsafe ones, but increasing the message verbosity will point you in the right direction. -- Peter N. M.
