IP 10.17.1.156 is the server that is having the issue.
IP 10.17.1.163 is the server where I issued 'ssh -X root@10.17.1.156' to get to Linux.
IP 172.24.8.30 is the Windows server where I attempted to connect via PuTTY.

Here is the tcpdump output form an SSH connection from another server running on the same VM as the server having the issue"

IP 10.17.1.156 is the server that is having the issue.
IP 10.17.1.139 is the server where I issued 'ssh -X root@10.17.1.156' to get to Linux.


Here is the output from 'ssh -vvv -X root@10.17.1.156'.
