So we found out that the tcp_wrapper banner on /etc/hosts.allow on the
RHEL7.1 X2go server was breaking the x2go client connection. Kept getting
the ŒProtocol Mismatch¹ error on the client. Once we modified the
/etc/hosts.allow file:
FROM
sshd: 137.78. 137.79. 137.228. 128.149. 127.0.0.1 : banners /etc/banners
TO
sshd: 137.78. 137.79. 137.228. 128.149. 127.0.0.1
The x2go client was able to connect to the server.
This seems to be a bug in X2go.
Thank you,
