Unable to use SSH/Microsoft Remote Desktop after Yosemite update
I ran into a similar problem after updating to Yosemite 10.10.1

Could you please check the output of tcpdump in another Terminal window, while you are connecting to your remote ssh server?

I have the suspicion you're hitting the same redirect-error I am seeing on my box recently :-/

How to get the information:


Open Terminal
type "sudo tcpdump -vv" --> hit return
Open another Terminal
Try to connect to your server via ssh
Look at the output of tcpdump and find the remote address of your server


If you do NOT see your server address, but rather some strange redirect (mine goes to gl02.opentracker.net):

Welcome to an unsolved, nasty problem-bug.
