#1476 fixed proxy control socket permission error B B


im trying to setup a working xpra proxy server. I followed https://xpra.org/trac/wiki/ProxyServer

im on 3x ubuntu 16.04 (proxyhost+targethost in docker containers and the client is a physical machine)

Xpra Version on all machines: v2.1-r15427

on the proxy server i start the proxy with:

xpra proxy :100 --bind-tcp= --auth=multifile:filename=/xpra-auth --no-daemon -d all
cat xpra-auth
cat /etc/passwd
nvidia-persistenced:x:106:109:NVIDIA Persistence Daemon,,,:/:/sbin/nologin

on the targethost

xpra start :11 --bind-tcp= --no-clipboard --no-pulseaudio --start-child="glxgears" --exit-with-child --no-printing --no-speaker --no-cursors --dbus-control=no --dbus-proxy=no --use-display --no-daemon

and on the client host

xpra attach --username=john --password-file=/password.txt tcp:i31forhlr4:10050
cat password.txt 

on the proxyhost i will get the following error:

2017-03-28 08:33:52,106 proxy video encoders: 
2017-03-28 08:33:52,106 new proxy instance started

2017-03-28 08:33:52,107  [Errno 13] Permission denied

on proxytarget i get

New tcp connection received from

Any ideas how to trace the problem? Which debug flag should i enable?
