[X2Go-Dev] X2go Mac client and Red Hat 7 server

[Real, Elizabeth (392K)]

1. Weird, I am subscribed but again did not get the notification. Maybe we
are blocking your domain.

2. Called ssh on the command line using the string provided and I logged
into my host, no problems. What does this step prove? Other than I¹m using
openssh keys to connect?

3. Did not change the client sshd_config file

4. We are testing X2go for our Red Hat 7 deployment. We are looking for a
low bandwidth remote desktop solution for some of our users.
