Weird scenario...

Hi all!! Well I would like to thank you all for your replies regarding root2. I will think about what I am going to do about this. I would like to ask you another thing now. I have a linux-box that connects to the internet via modem. The ip that it gets is dynamic, ie it changes everytime it logs in. Can someone tell me a way to create something like an automated e-mail message that the server will send to me whenever it logs on and inform me of its local ip assigned from the ISP? This is a weird situation because I have to leave the city for a few weeks and I would like to be able to ssh to the server whenever it logs on the internet. Can someone please help me with this?? Thank you all again for your help! Regards Chris
