(*finger raised politely*) I already read it!, can I have those scripts,
please ?... ;-)
If I may add, as for your question:
Ofcourse you can - you can do anything (almost) with Linux (and this is
not empty words). BUT, it will take you to a quick tour of many
networking issues under linux, though not too deeply, and even more if
you intend to have some *minor* access control to your linux machine
connected to the Internet (*highly* recommended and quite quick and
easy). This all means it will take some time of yours (I cant see any
"effort" here but merely time, as with probably all computer subjects,
again, IMHO :-)
This is a draft "shopping list" of the issues you would need to go
through on your Linux machine (which will be a "GATEWAY" to the net -
that's the term):
1. Set up hardware support on both machines for the ethernet cards
(possible kernel recompilation - but only if your current kernel don't
recognize the network hardware).
2. Set both win & linux machines IP numbers (on the ethernet cards - not
on Dial up adapters) (if you wanna do it with proper IP numbers - the
network should have the 192.168.x.x network address, e.g. the Linux eth0
device should have something like 192.168.1.1 and your windoze should
have 192.168.1.2) . Setup the linux machine's IP as your default gateway
for your windoze.
If you dont have prior experience with that stuff use "netconf" of
"linuxconf" (and pray it's bugs wont havoc your machine :) ... [I cant
recall the HOWTO's exact names in which this stuff lies, but a simple
browse in the HOWTO's index will let you find those.]
3. Set up masquerading on your linux machine. that's easy (the basic is
merely 3 (right?) ipchains commands. [ it's desribed, as Ira said, both
in the IPChains and Masquerading HOWTOs]
4. I strongly recommend that you use TCPWRAPPER for your linux gateway
so "friendly" people from the net couldn't telnet, for example, to your
home machine while you could do so from the windoze machine!. setting up
basic firewall rules should not be too difficult too (but I personally
haven't implemented that yet).
[TCP Wrapper docs, in /usr/docs/, and their manual pages are pretty
good. perhaps there's an HOWTO for that too.]
Now, what didn't I mention?... (continue here)
BTW, it all makes me wonder - is there a "home networking HOWTO"
somewhere ?
Boaz.
