Took a look at the available SSH client options, and I do not see an obvious 
way to pass through the client hostname/IP/identity to the server.  Here are 
the two options I see:- As mentioned before, you can use the Execute Command 
parameter to pass through the identity using the token.  You'd have to set up a 
startup script or something like that, or figure out the right way to use the 
execute command option to set a variable and then launch the shell or whatever 
application you want to launch with that variable.  This is the only way to do 
it currently, and probably the best bet.- It is possible to set up SSH clients 
and servers to send environment variables between the client and server.  I 
would imagine Guacamole could be tweaked to add this functionality...but...it 
seems like a little bit of a corner case to add, particularly given that you'd 
have to both configure Guacamole to have some map of arbitrary environment 
variables and values (and sanitize them for security purposes), and, in order 
for this to work, the SSH server has to be configured, not just to allow 
variables, but with the specific list of variables that you want to pass 
through.  That's a lot of extra configuration to allow this behavior - 
particularly given the fact that you can just do it on the command line.

Tjareson,While RDP currently has an option to pass through the client name, SSH 
does not.  I need to look and see if there's an easy way to enable this 
functionality in Guacamole, but the only thing I'd suggest today is that you 
might be able to find a way to use the "Execute Command" parameter for SSH 
connections to pass in that token.

Hi,

I'm using an ncurses based database application, which makes use of the 
IP address of the ssh session from which it got used to e.g. chose the 
right printer, rfid reader etc.
This became web enabled now with guacamole and I was wondering if there 
is any easy way to get hold of the IP address of the web session which 
is used to connect via ssh to that application mentioned above.

The setup is like this:
user <-> nginx <-> tomcat <-> guacd <-> ssh <-> ncurses application

All components from nginx to the ncurses application are on the same 
server. But of course from the application side it looks always that the 
connection is coming from where tomcat/guacd sits, so 127.0.0.1 in this 
case.
I could probably somehow browse through all logs, 
/proc/<process-id>/status and netstat to somehow figure out, who is 
talking with whom, but I hope there is a more convenient approach for 
this? I found that there is ${GUAC_CLIENT_ADDRESS} but I'm not sure if 
there is any way to hand that over via ssh session.

regards
Tjareson
