Still in the process of migrating from an old CentOS5 server to a brand
new CentOS7.
After finally getting Virtualbox-5.0 installed and a new Wondoze10 Pro
installed it became time to shift the data from the old server to the new.
The old server is headless and I installed the old WindozeXP into the
Virtualbox4.x via the command line.
To do some of the admin I needed to attach to the windoze via a gui and
used rdesktop via an ssh tunnel of port 3389. This "just worked" with my
old CentOS6 laptop and workstations.
So now I try to connect to the old server via my laptop also running a
recent CentOS7 install using rdesktop - no joy.
the ssh command is
>ssh servername -L 3389:127.0.0.1:3389
and then also from my laptop
rdesktop -a 16 -N 127.0.0.1:3389 -u rkampen -p-
only to get
ERROR: Failed to open display:
various google searches offer suggestions
prepending
DISPLAY=:0.0
gives
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
ERROR: Failed to open display: :0.0
tried setting selinux to permissive mode - still no joy.
All this just worked with my old CentOS6 laptop and work station,
however I no longer have access to that.
I guess there have been some "improvements" with the advent of gnome3
that now prevent this from working, however my knowledge of how this
rdesktop interacts with the local display manager are sketchy at best.
Any suggestions from those of you that understand this stuff way better
than I do?
TIA
Rob
