On the page ​http://winswitch.org/dev/, the link "Download the latest source" lists "(version 0.12.16 released 2013-11-05)" while the href points to winswitch-0.12.20.src.tar.bz2

Important:

• it needs a man page - this is a debian requirement: all public commands (ie: /usr/bin/) need a man page, even if it is a small one that refers to another one

More minor issues:

• how do you create your config files? this needs to be documented somewhere, maybe providing an example config with comments in /usr/share/winswitch/launcher-example/
• I've removed the default values from LauncherSession to ensure they are populated correctly from file - the code should ensure the values make sense (port>0, host.len>0)
• LauncherClient should show a warning if the session fails to start
• file mime-type mapping so users can double click on them and have the software automatically launched
• dealing with ssh-tunnels (totally non-trivial)

xterm started as application session on the remote server runs with umask 0000. This has security impact as files/directories created by users are then world-writable. Expected: some sensible default like 002 or 022.

Version: winswitch 0.12.23-1, xpra 2.1.1-r16658-1

Possible cause: winswitch server assumes umask will be set in /etc/bashrc. That is true on Red Hat derived systems. But it is not true on Ubuntu (tested 16.04 LTS) where I think umask is expected to be set by PAM session (pam_umask.so).

Perhaps related, the PAM file provided by /etc/pam.d/xpra seems to assume a Red Hat style system and most of the PAM modules referenced there do not exist on a Ubuntu system.
