What could be the problem with my osx 10.8.5 MAC and SSH? I can ping a remote computer from my Mac OSX 10.8.5.
I can ssh to a remote machine from another Linux computer. But I can not ssh to a remote machine from my MAC using an IP address or long name. I was able to do this before, now it no longer works. I do not know how this happened. I installed NoMachine on my MAC, but I'm not sure if this caused it.
$ ssh -vvv 73.x.x.x_some_ipaddress
