I've set up a jail, installed the latest xrdp from ports (and later also tried the current version from github), but my session immediately disconnects after I attempt a connection via remmina.
The logs don't tell me much - session manager tells me, that the session just ended unexpectedly early. I put
My /usr/local/etc/xrdp/startwm.sh:
Excerpt from /var/log/xrdp-sesman.log running a session:
Now, I'm wondering - is it even possible to run xrdp in a jail? I understand, I can't run X11 in a jail unless I somehow managed to expose all the necessary memory regions and - if I understand it right - it doesn't work out of the box. Then again, xrdp runs a virtual fb server, I thought?
I've put devfs rules to ruleset zero, exposing all devices, but it didn't make any difference.
If anybody got any pointers, I'd very much appreciate it. Next thing to try is a bhyve vm instead, I suppose.
The logs don't tell me much - session manager tells me, that the session just ended unexpectedly early. I put
exec xterm in my /usr/local/etc/xrdp/startwm.sh. Logging the output of xterm tells me, that the X session just went away.My /usr/local/etc/xrdp/startwm.sh:
Code:
#!/bin/sh

# This script is an example. Edit this to suit your needs.
# If ${HOME}/startwm.sh exists, xrdp-sesman will execute it instead of this.

I understand, I can't run X11 in a jail unless I somehow managed to expose all the necessary memory regions and - if I understand it right - it doesn't work out of the box.

I've put devfs rules to ruleset zero, exposing all devices, but it didn't make any difference.
If anybody got any pointers, I'd very much appreciate it. Next thing to try is a bhyve vm instead, I suppose.
