Hi Nick,
Everything is running from guac 1.1.0.
There's no messages from dmesg on the RDP host.
guacd reports on the server:
Apr 15 12:54:41 remotelab guacd[17580]: guacd[22724]: WARNING:
Received clipboard data cannot be sent to the RDP server because the RDP
server has requested a clipboard format which was not declared as
available. This violates the specification for the CLIPRDR channel.
This looks to be when I do a cut operation. Any thoughts on what this
would be? I'm running the epel package of xrdp.
I see a few core dumps from guacd on the server as well, but not at the
times when I'm doing this... likely some other issue:
[328607.147080] guacd[822]: segfault at 7f0e0aba401c ip 00007f0e1252389b

libguac-client-rdp.so.0.0.0[7f0e124fe000+3b000]
I did restart guacd and it didn't help.
Jason.

Hi.
I have an odd situation occurring. I'm connected (through Guac) to a
CentOS 7 machine via RDP. The desktop environment is the standard
GNOME. I have only a terminal window open. When I select text in
the
terminal window, then right-click and select "Copy", the RDP session
disconnects and Guacamole reports "The remote desktop server is
current
unavailable. If the problem persists, please notify your system
administrator, or check ...". It then reconnects, but if I choose
"paste", the text I cut is not in the buffer. Any ideas on how to
solve?
Sounds like something is crashing - you'll need to narrow down if it
is xRDP or guacd that is exiting abnormally. I'd start with the
following:
- Take a look at "dmesg" output on the systems running both xRDP and
guacd and see if you see any "segfault" messages.
- Look at syslog on both systems and see if you can see any reason
given for either xRDP or guacd crashing.
- Look at the system running guacd and see if the log messages in
syslog (journalctl, /var/log/messages, etc.) and see what guacd is
saying is the reason for the connection closure.
Also, what version of guacd are you running?
