[NTLUG:Discuss] Help with ssh

[Fred]

Another issue has cropped up.

My main puter has several users. I usually log into
my personal acct and ssh -X to the others as needed
for various activities: mail, invoices, etc It may not
be the optimum solution but it has worked well for
a few years now. The usual access to those accounts
is:
fred -> ssh -X -p2279 username at localhost

then input the password and go. I am now in the 
process of moving everything over to another
puter and need to look at these accounts with 
the new box. When I substitute the main's IP address
in place of "localhost" in the above example,
the process starts and then hangs. The title
bar of the console window is labeled with the
username and IP address of the old system, so 
it gets that far along. Here is the output of the -v option:

 fred at new:~> ssh -v -X -p 2279 username at 192.168.1.102
OpenSSH_6.2p2, OpenSSL 1.0.1j 15 Oct 2014

debug1: Enabling compatibility mode for protocol 2.0
debug1: Local version string SSH-2.0-OpenSSH_6.2
And then it hangs....

Yes, both machines are on the same LAN. Obviously
I am missing something very basic but it eludes me.
Any helpful pointers would be appreciated.

Thanks,
Fred
