Hello everybody, I try to set up a remote pair programming environment with xpra. Development takes place on a cloud server. Both programmers are connected via xpra. The idea is, that in this way we don't need much bandwidth on upload (only the keystrokes and mouseclicks). The bigger data volume (screen content) is only on download and thus less problematic.
As an example, I want to run a terminal window on the server and share it on both clients. All involved machines run debian strech (yet). On the server I start a session with $ xpra start :30 --sharing=yes then I start mate-terminal on that server. On the first client, I attach with $ xpra attach ssh:m...@xxxxx.org:30 --desktop-scaling=off --quality=100 --sharing=yes This works as expected, I see and can use the terminal. On the second client, I try to share with $ xpra shadow ssh:m...@xxxxx.org:30 and get no connection. Error messages are below. Whats wrong? Any hints? --------------------------------------------- output from: xpra shadow ssh:m...@xxxxx.org:30 --------------------------------------------- 2017-12-28 19:07:28,614 Xpra gtk2 client version 0.17.6-r14322 2017-12-28 19:07:28,615 running on Linux debian 9.3 2017-12-28 19:07:28,616 Warning: failed to import opencv: 2017-12-28 19:07:28,616 No module named cv2 2017-12-28 19:07:28,616 webcam forwarding is disabled 2017-12-28 19:07:29,128 GStreamer version 1.10 for Python 2.7 2017-12-28 19:07:31,004 PyOpenGL warning: missing accelerate module 2017-12-28 19:07:31,689 detected keyboard: rules=evdev, model=pc105, layout=de 2017-12-28 19:07:31,692 desktop size is 1920x1080 with 1 screen: 2017-12-28 19:07:31,699 :0.0 (508x286 mm - DPI: 96x95) workarea: 1888x1080 at 32x0 2017-12-28 19:07:31,711 monitor 1 (531x298 mm - DPI: 91x92) xpra initialization error: failed to identify the new server display! 2017-12-28 18:07:48,639 server failure: disconnected before the session could be established 2017-12-28 18:07:48,639 server requested disconnect: server error (failed to start a new session) Warning: cannot use the system proxy for 'shadow' subcommand, FAILURE Entering daemon mode; any further errors will be reported to: /home/max/.xpra/:30.log xpra initialization error: failed to identify the new server display! 2017-12-28 18:08:04,139 server failure: disconnected before the session could be established 2017-12-28 18:08:04,139 server requested disconnect: server error (failed to start a new session) Warning: cannot use the system proxy for 'shadow' subcommand, FAILURE Entering daemon mode; any further errors will be reported to: /home/max/.xpra/:30.log xpra initialization error: failed to identify the new server display! 2017-12-28 19:08:19,979 The SSH process has terminated with exit code 0 2017-12-28 19:08:19,980 the command line used was: 2017-12-28 19:08:19,980 ssh -x -l max -T xxxxx.org xpra initenv;~/.xpra/run-xpra _shadow_start :30 || $XDG_RUNTIME_DIR/xpra/run-xpra _shadow_start :30 || xpra _shadow_start :30 _______________________________________________ shifter-users mailing list shifter-users@lists.devloop.org.uk http://lists.devloop.org.uk/mailman/listinfo/shifter-users
