[X2go-dev] x2go plugin and proxy?

[Heiko Baumann]

 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.
