All my attempts to access a Centos 7 machine from Fedora 20 using x2go
have failed with these error messages in /var/log/secure:
Nov 17 16:42:08 datium sshd[4175]: Accepted publickey for dad from

The Centos 7 machine is virtualized in kvm, running on another F20
machine, but that shouldn't matter.
ssh is configured to allow access via public/private keys and works
fine.
sshd seems to have a problem with "subsystem request for sftp",
whatever that means, but I have verified that I can run 'sftp datwizkvm'
and get access to my home directory there.
When x2go has negotiated the public key transaction, an XFCE window
pops up for about 1 sec and then vanishes. This leads me to speculate
that the problem is more to do with starting X than making the
connection.
In the opposite direction, x2goclient on the Centos 7 machine will
happily open and run an XFCE display of the Fedora 20 machine.
Does anyone have insight about why the connection is asymmetric?
Has anyone experienced this kind of failure?
Any hints how to fix it?
