[winswitch] Xpra proxy with --auth=allow does not work

Wed Aug 31 23:55:41 BST 2016

OK. Upgraded my ubuntu distributon to Xenial and then got the xpra 1.0 from beta. Still, cannot get it to work. Any help?

started proxy like this
-- xpra proxy :13 --bind-tcp=0.0.0.0:10002--tcp-auth=multifile:filename=/home/ubuntu/xpra-auth
started a couple of servers on same machine like this
-- xpra start :11 --bind-tcp=0.0.0.0:10000
-- xpra start :12 --bind-tcp=0.0.0.0:10001
-- DISPLAY=:11 xlclock &
-- DISPLAY=:12 xlogo

try to attach from windows machine
-- Xpra_cmd.exe attach --username=ubuntu --password-file=pswd.txt tcp/52.53.168.31/10002/11

Everything seems to go well in the beginning. No error message. It simply drops the connection without saying anything.

Here is the log from proxy :-

I assume you must be using an older distribution like Ubuntu Trusty?

Please try with the current beta packages, the next release will support
those older distribution versions and it includes a large number of
fixes for the proxy server:
http://xpra.org/trac/ticket/952
http://xpra.org/trac/ticket/1264
Many of those features and fixes are not available in the branch you are
using.

Cheers
Antoine
