hmm, maybe x2goclient can read proxy settings from (default) browser and use openssh ProxyCommand with an helper app to do the work. but if the proxy need authentication this helper app needs to handle it.

From my perspective... No thanks on the Java! I'm sure there must be
other simpler ways to implement.

openssh's ProxyCommand needs an external tool which does the proxy
connect (with auth if required). so the x2go plugin must know proxy
ip, proxy port and, if required, proxy user and pass. i dont know if
this information is available to an firefox addon (i hope not
specially for the auth stuff ;)).

maybe it is easier to use some kind of java browser plugin to create a
local socket to listen on and forward this socket (via browser proxy
settings/HTTP CONNECT) to the x2goserver. this way it should be
possible to use the browser proxy settings (if java is configured this
way -> Java Control Panel). x2goclient could connect to this socket
(localhost:someport) without doing any proxy related stuff.

however this will only work if ssh is listening on port 443 on
x2goserver because most proxies only allow HTTP CONNECT on port 443.

You need to forward ssh traffic through an ssh proxy? Why? That is
inefficient - can't you just make the remote server visible on some
port?

I am connecting from LAN hidden by an http proxy. I.e. it is not
possible to simply "ssh -p 443 x2goserver.com", but the connection must be passed through a proxy at "some.local.proxy.address" at port 8080
(the proxy is without authentication).

Putty allows for proxy setup. I also checked the man page of ssh, it has
an option "ProxyCommand", which would probably be "connect
some.local.proxy.address 8080\n".

So the question probably is how to incorporate that ssh option into x2go
plugin.
