VNCserver IP questions

This is something I have been thinking about. If I am connected from a windows box to a linux box located remotely(I am using Dialup), and I use the linux box to telnet out to another remote site, what IP address will the remote computer see as my IP address, will it see the linux box's IP, or would it trace through my VNCserver to my windows box. If it shows the IP of the linux box, is there anyway to see the IP of the windows box that I am on. Thanks for your replies. =)

Your not hacking are you?

The IP address the remote computer will see would be the linux box unless its masq from a firewall/router.

I will admit im usure if the remote computer could see the ip of the windows box but definitly the windows box. But your actions would probably be logged on the linux box.

Just a quick tip for you. Instead of telnet use ssh.
This will provide you with extra security. IE: Passwords will not be sent in clear text like telnet.

No, I am not hacking, I am just wondering if there is a way to see the windows box that the linux box is being accessed through using VNC. Anybody else that knows whether it is possible to find the IP address of the windows box, knowing the IP address of the linux box, and knowing that the linux box is being used through VNCserver? Thanks to all replies in advance

lhiggins is right.

PC1 (VNC viewer) - PC2 (VNC server) - PC3 (Telnet server)

Unless PC3 has access to PC2 and runs "netstat -n" or it is running a packet capture utility, there is no way for them to know that there is a VNC connection to PC2. Even when you are VNCed the local user usually still has control of the system so it may as well be them hacking (cough) into PC3.
