Cable Modem + Router

Hi; I'm evaluating Xmanager now, and I'm trying to connect my Unix box at my office from my home, where I have a cable internet connecetion and router connected to it. Since router assigns an internal IP address to my PC (usually 192.168.x.x), Xmanager is not able to open up. Is there anything that I can do for this? Thanks... Ugur

Re: Cable Modem + Router

After, I've posted th eprevious messgae, I've figured out that I nedd configure the router with some forwarding rules. In the forwarding rule, I've forwarded incoming TCP port 6000 to my PCs TCP port 6000, however still does not work.
Do you ghave any idea how can I solve this?

Re: Re: Cable Modem + Router

After configuring the forwarding rule, you need to modify a command line in the Xstart program. The "-display $DISPLAY" option should be:

/usr/bin/X11/xterm -display IP_of_router:0.0

Also, check if a firewall feature is turned on in your Windows.

Maybe instead of opening your TCP ports, you could use SSH tunneling
to connect to your office.


1) your home machine initiates the connection, so you
don't need to open ports (that someone could use to enter your
home machine if there are bugs in the implementation)

2) all your connection runs encrypted and authentified, so you have added security and protection from people "spying" the traffic
in all the hosts in between your home and your office.

Try the SSH option from the Xstart program that Xmanager has.
You'll probably get a x-window session without window managers
and stuff like that, that you'll need to run yourself one by one.

But after you know what you need, you can put that in a start script our something. Don't ask me about the latter part, I know the theory but never have done it!!! I just know it can be done :-)

my two cents
