I have been using MobaXterm as my SSH client for many months, with mostly no problems. Good thing I've kept PuTTY installed "just in case"
On Tuesday I was able to SSH in to my Cisco gear - which all look to CPPM for RADIUS auth - and then last thing Tuesday I patched ClearPass.
Being snowed-in meant I couldn't test on Wednesday.
Thursday I couldn't connect from MobaXterm's SSH client, but PuTTY could. I just realized that the change coincided with the patch.
Anyone got an idea what to troubleshoot first?
