I discovered Xpra several years ago, but never really used it until I was searching for a solution to make Wireshark available via a Webinterface. Using Docker and the Xpra HTML Client, I was able to create a Docker container with Xpra and Wireshark (see https://github.com/ffeldhaus/docker-wireshark). Based on the Docker image, I created a solution to proxy and analyze arbitrary TCP traffic with HAProxy and Wireshark - HAProxy acts as endpoint for e.g. NFS, SMB, HTTP or other services and forwards the traffic to the real service and Wireshark, accessed via Webbrowser, can analyze the traffic (see https://github.com/ffeldhaus/docker-network-traffic-analyzer for details).

I’m impressed by the features and abilities of Xpra and would like to thank everyone who helped to develop it.

During testing of the solution I discovered a few things were I would like to ask for your input:
- Installing Xpra requires a huge number of dependencies. It would be great to get some input how to reduce the number of dependencies to create a minimal docker image (currently it’s larger than 1GB.
- Running current stable Xpra version results in several error messages (see below). I’d appreciate input why these occur (check https://github.com/ffeldhaus/docker-wireshark/blob/master/xpra.conf for the config options). I’d be especially interested in
- Why does renaming '/run/user/1000/xpra/Xorg.S1.log' to '/run/user/1000/xpra/Xorg.:0.log' fail?
- Why does Xpra try to create socket directory in '/run/xpra' even though socket dir was specified as /run/user/1000/xpra and xpra was run as non root user?
- Why does Xpra show an ERROR related to X11 property 'PULSE_SERVER' even though pulseaudio=no is specified in config file?
- When I access Wireshark via Webinterface using Firefox 57 I have issues with special characters (y and z are working correct, but ! = # as well as öäü and others are not working). I’ve seen some fixed issues around this, but this seems to be a new one. With Chrome it works better, but not perfect (! = # work but öäü do not work). Should I report this as an issue?
- Is it possible to force SSL connections when accessing the HTML client? I successfully configured SSL, but ideally all HTTP connections should be upgraded to HTTPS (maybe using HSTS).

I’m impressed by the features and abilities of Xpra and would like to thank everyone who helped to develop it.
- Installing Xpra requires a huge number of dependencies. It would be great to get some input how to reduce the number of dependencies to create a minimal docker image (currently it’s larger than 1GB.
1GB is huge! The most important dependencies are listed here:
http://xpra.org/trac/wiki/Dependencies
And the build and packaging dependencies are also documented here:
http://xpra.org/trac/wiki/Building

This will largely depend on the distro you are on. Some Debian it seems?
Our Debian packaging uses strict dependencies as well as both
"Recommends" and "Suggests" weak dependencies.
Not installing the weak dependencies will give you a stripped down
installation, without support for printer or audio forwarding, mdns, etc
For your use-case, you may also want to remove "ffmpeg-xpra" as per:
http://xpra.org/trac/changeset/17145

- Why does renaming '/run/user/1000/xpra/Xorg.S1.log' to '/run/user/1000/xpra/Xorg.:0.log' fail?
That's a bug in the Xorg server, a fix has been submitted upstream:
http://xpra.org/trac/ticket/1192
Post by Feldhaus, Florian via shifter-users
- Why does Xpra try to create socket directory in '/run/xpra' even though socket dir was specified as /run/user/1000/xpra and xpra was run as non root user?
See "socket-dirs" as well as "socket-dir".
(yes, it is a bit confusing having both, we kinda messed up that one -
too late to go back, sorry)
Post by Feldhaus, Florian via shifter-users
- Why does Xpra show an ERROR related to X11 property 'PULSE_SERVER' even though pulseaudio=no is specified in config file?
The "_sound_query" subcommand is probing gstreamer to see what elements
should be used for audio forwarding, and part of this query will try to
figure out if pulseaudio is available. (which is separate from the
pulseaudio=no command line option which controls if we start it or not)

For whatever reason, your "/usr/bin/xpra" ends up trying to use GTK3
(maybe loading GTK2 failed?), this doesn't work well before xpra 2.2

- When I access Wireshark via Webinterface using Firefox 57 I have issues with special characters (y and z are working correct, but ! = # as well as öäü and others are not working).

Yes please. Make sure you include all the required details:
https://www.xpra.org/trac/wiki/Keyboard#ReportingBugs

Keyboard mapping issues are always "interesting".
Post by Feldhaus, Florian via shifter-users
- Is it possible to force SSL connections when accessing the HTML client? I successfully configured SSL, but ideally all HTTP connections should be upgraded to HTTPS (maybe using HSTS).
In xpra 2.2, you can specify different socket types for different ports.
For example:
xpra --bind-wss=0.0.0.0:14500
This will only allow secure websockets / https.

For more information, see:
https://xpra.org/trac/ticket/1504#comment:2

"Recommends" and "Suggests" weak dependencies.
Not installing the weak dependencies will give you a stripped down
installation, without support for printer or audio forwarding, mdns, etc
http://xpra.org/trac/changeset/17145
I managed to reduce the docker image size quite a bit (to 480MB) by using the --no-install-recommends switch for apt-get install. Unfortunately changeset 17145 was not included in the latest available xpra 2.2 beta which is from yesterday morning. Could you trigger a new xpra 2.2 beta build for centos including that changeset?

I did see a few new errors though:

The following is probably related to python-uinput not being installed. If it is required, it should be a mandatory dependency. If it is not required, xpra shouldn’t fail.
2017-10-11 07:21:44,355 cannot access python uinput module:
2017-10-11 07:21:44,355 No module named uinput

The following is new as well
Error running "xauth add :0 MIT-MAGIC-COOKIE-1 7e0f55cb5f2a433993a09f12bcea0794": [Errno 2] No such file or directory

Even though I included dbus-control=no and dbus-proxy=no I still get this error:
/bin/sh: 1: dbus-launch: not found
dbus-launch failed to start using command 'dbus-launch --close-stderr':
exit code is 127

2017-10-11 07:21:54,388 cannot load dbus helper: No module named dbus

The following is also new and I would like to understand if I should install this package as dependency. For what does xpra use the package?
2017-10-11 07:21:54,404 Warning: the python netifaces package is missing

There is one message regarding Gstream which I don’t understand

For whatever reason, your "/usr/bin/xpra" ends up trying to use GTK3
(maybe loading GTK2 failed?), this doesn't work well before xpra 2.2
This seems to be fixed in xpra 2.2. The only error left is the following, which I understand should be a warning:
2017-10-11 07:21:56,950 Error: failed to query sound subsystem:
2017-10-11 07:21:56,950 query did not return any data

- When I access Wireshark via Webinterface using Firefox 57 I have issues with special characters (y and z are working correct, but ! = # as well as öäü and others are not working). I’ve seen some fixed issues around this, but this seems to be a new one. With Chrome it works better, but not perfect (! = # work but öäü do not work). Should I report this as an issue?

- Is it possible to force SSL connections when accessing the HTML client? I successfully configured SSL, but ideally all HTTP connections should be upgraded to HTTPS (maybe using HSTS).
In xpra 2.2, you can specify different socket types for different ports.
xpra --bind-wss=0.0.0.0:14500
This will only allow secure websockets / https.
https://xpra.org/trac/ticket/1504#comment:2
Using --bind-wss works to enfore SSL when using xpra 2.2.

http://xpra.org/trac/changeset/17145
I managed to reduce the docker image size quite a bit (to 480MB) by using the --no-install-recommends switch for apt-get install. Unfortunately changeset 17145 was not included in the latest available xpra 2.2 beta which is from yesterday morning. Could you trigger a new xpra 2.2 beta build for centos including that changeset?
I wasn't 100% sure which specific distro versions you needed here, as
you've mentioned both "apt-get" and "CentOS", so I've pushed some new
2.2 beta 64-bit builds for Ubuntu Zesty and Artful, Debian Stretch, all
current versions of Fedora and CentOS 7.4.
And for good measure, also MS Windows and MacOS.

The following is probably related to python-uinput not being installed. If it is required, it should be a mandatory dependency. If it is not required, xpra shouldn’t fail.
2017-10-11 07:21:44,355 No module named uinput
This is not a failure, just an informational message.
Warnings and errors are printed in orange or red to a terminal output,
and they are preceded with the string "Warning" or "Error".

uinput is optional, for more information see here:

Error running "xauth add :0 MIT-MAGIC-COOKIE-1 7e0f55cb5f2a433993a09f12bcea0794": [Errno 2] No such file or directory
This usually happens when the XAUTHORITY file cannot be created or
accessed. I'm not sure why this would be a new thing.

- Why does Xpra try to create socket directory in '/run/xpra' even though socket dir was specified as /run/user/1000/xpra and xpra was run as non root user?
See "socket-dirs" as well as "socket-dir".
(yes, it is a bit confusing having both, we kinda messed up that one -
too late to go back, sorry)
Using socket-dirs instead of socket-dir fixed this.

- Why does Xpra show an ERROR related to X11 property 'PULSE_SERVER' even though pulseaudio=no is specified in config file?
The "_sound_query" subcommand is probing gstreamer to see what elements
should be used for audio forwarding, and part of this query will try to
figure out if pulseaudio is available. (which is separate from the
pulseaudio=no command line option which controls if we start it or not)
For whatever reason, your "/usr/bin/xpra" ends up trying to use GTK3
(maybe loading GTK2 failed?), this doesn't work well before xpra 2.2
2017-10-11 07:21:56,950 query did not return any data
As per above, the sound subsystem requires gstreamer and you have not
installed the python bindings, or gstreamer, or both.

Hi Antoine,

thanks for rebuilding it for Debian stretch. Unfortunately the ffmpeg-xpra package is still required. I think you missed to remove it from the Build-Depends section in the Debian Control file:

Source: xpra
Section: x11
Priority: optional
Maintainer: Antoine Martin <***@devloop.org.uk>
Build-Depends: debhelper (>= 8)
,cython (>= 0.23)
,ffmpeg-xpra

Can you have check if removing it from the Build-Depends is possible and then rebuild the Debian packages?

Thanks

Hi Antoine,

Please post the exact packaging diagnostic messages.

Can you have check if removing it from the Build-Depends is possible and then rebuild the Debian packages?
We can't remove the build time dependency, as it is really needed.

If the binary packages generated still somehow have a dependency on
ffmpeg-xpra (or was it the .so libraries themselves?), we may need to
either add more dh_shlibdeps overrides or split the codecs into their
own package.

Not sure I'll have much to investigate either option in the near future,
but you can easily do this yourself by following:
http://xpra.org/trac/wiki/Building/Debian
(some tweaking may be required)
