I've installed Feisty -- now need to get Comcast HSI up & running........

[George Ernest Noon]

all,
	I've installed Ubuntu Feisty with a disk I got
at our 10.18.07 Release Party ----
it works great; although i did have premonitions of
being totally without printing ability, with my Epson
Stylus C66, those worries were totally unfounded: it was
up and happily printing in just a few clicks.
Internet connection & e-mail is a different story, though;
mostly on account of two things, I believe:
1. Comcast High Speed Internet lists Linux as 'unsupported'
& 2. my own inexperience
I guess, now that I've switched my keyboard, mouse, speakers,
Ethernet cable and monitor cable back over to my older
Pent3 533MHz 512MB Ram Windblows machine, I'll do some
searching through its Internet & e-mail settings (in Firefox &
Thunderbird, as well as through Control Panel) - get all the
settings i can find down on paper; but I guess the IP address I'll
need has to be that of my Ubuntu Box. Question, how do I find
the IP address of the computer, since it is evidently not
just automatically filled in?
Hey!; enough for now: I tend to go really wordy, if I'm not
careful. Thanks greatly in advance for any & all help.
