#20 Receiving error 'Unable to connect' when attempting SSH

[commmorancy]

I'm on a Mac running Sierra. SSH shows 'Unable to connect' immediately on any host including 'localhost'. SSH works fine from a terminal. I've used kSar 5.0.6 in the past on a different Mac and have had this working. However, on my newest MacBook, I am receiving 'Unable to connect' on any SSH attempt. The Java version installed is 1.8.0_112 and I'm concerned that this version of Java may not be compatible. What Java version should I be running? It also seems that kSar can perform logging of failures, but I do not see a way to enable the log to find out what the issue is. BTW, I have also tried this with 5.1.0 beta and I'm getting an entirely different failure (a long java trace dump) with that version.

Any help in getting this fixed would be appreciated. Please let me know.
