Interestingly, when I try running the server on ussd-prd-rdln02 (a different machine that shares the same networked filesystem), the client is able to connect to that! I guess I could just use ussd-prd-rdln02 but it would be good to figure out why it doesn't work on ussd-prd-rdln01, because my ultimate goal is to install xpra on a third machine that has a more complicated network topology than either of these.

Try running the client from the command line and look for clues in the output, maybe also keep an eye on your ssh server log to verify that the client does make an ssh connection with the correct credentials. Something like: Xpra_cmd.exe attach ssh://username:password@host:sshport/ Assuming you only have a single display active (verify by running "xpra list") this should work, otherwise specify one: Xpra_cmd.exe attach ssh://username:password@host:sshport/DISPLAY > The server prints: > [bmishkania@ussd-prd-rdln01 ~]$ > XPRA_SYSCONF_DIRS=/home/bmishkania/bin/xpra-2.2.3/etc/xpra/ xpra start > --start=~/bin/firefox/firefox --daemon=no > 2018-01-27 10:41:51,460 cannot access python uinput module: > 2018-01-27 10:41:51,460 No module named uinput > 2018-01-27 10:41:51,957 Warning: failed to create socket directory > '/run/xpra' > 2018-01-27 10:41:51,958 [Errno 13] Permission denied: '/run/xpra' > 2018-01-27 10:41:51,961 created unix domain socket: > /run/user/109999/xpra/ussd-prd-rdln01-100 > 2018-01-27 10:41:52,264 created unix domain socket: > /home/bmishkania/.xpra/ussd-prd-rdln01-100 > 2018-01-27 10:41:52,265 Warning: cannot create socket > '/run/xpra/ussd-prd-rdln01-100' > 2018-01-27 10:41:52,265 [Errno 2] No such file or directory > 2018-01-27 10:41:52,265 /run/xpra does not exist > 2018-01-27 10:41:52,266 user 'bmishkania' is a member of groups: no groups! > 2018-01-27 10:41:52,266 missing 'xpra' group membership? > 2018-01-27 10:41:52,267 failed to query path information for > '/run/xpra': [Errno 2] No such file or directory: '/run/xpra' > 2018-01-27 10:41:52,689 Warning: zlib is the only compressor enabled > 2018-01-27 10:41:52,689 install and enable lzo or lz4 support for > better performance Once you get going, you should do something about this warning and try to stuff the python-lz4 (and lz4 if not installed) RPM contents into your local home environment.

You may also hit crashes when running without some of those codecs dependencies installed if the system provides a different version of the same library.
