How to access someones computer via the internet. 
(with their co-operation)

If you want someone to be able to login to your computer while your on the internet. Simply send them your internet address (which changes, everytime your dialup your ISP.) and if they have access to your computer they can simply 
telnet 204.19.191.73 into your compuer!!!

Logon to your ISP, onces your connected execute the following command:

/usr/etc/ifconfig -a

What your looking for is the internet address for your computer at that moment. (Most internet address change everytime you call your ISP.)

Here's what the output looks like: (The number your looking for is in BOLD)

lo0: flags=869<UP,LOOPBACK,NOTRAILERS,RUNNING>
        inet 127.0.0.1 netmask ff000000 
ppp0: flags=51<UP,POINTOPOINT,RUNNING>
        inet 204.19.191.73 --> 204.19.191.1 netmask ffffff00 
ppp1: flags=10<POINTOPOINT>

Onces you have that info, email them the internet address number and they will be able to logon to your computer using telnet 204.19.191.73 command!!!

Simple!!!

Here's what it looks like:

blanche.videotron> telnet 204.19.191.73
