Dual-boot: Different static IPs?

I have a small lan behind a dsl modem/router, with all machines using static
IPs, I guess from their host file.

I'd like a dual-boot Win/linux machine to use different IPs according to
whether it is in Win98 or Linux. Is it as simple as setting a different IP
in the host files?

(I want to block most outbound ports when running Win98 but not when in
Linux, and thought the easiest way is to assign the machine a different IP
address when in Win and then block all out ports on the router for that IP
address.)

As you can probably tell, I'm a bit of a network newbie.

Thanks,
Nick

No, the host file only associates a name with an
address. You must assign the address elsewhere.

Oowwwwwrrongski!

The hosts file defines address <-> name mappings, nothing else.

And then again, yes, it is as simple as that, except not in the hosts file.

Not too helpful there, scary...

In win98 : open up the network properties box (look arond..), and open the
properties for TCP/IP networking (last entry usually)

Set your IP address and mask here, also set the gateway to the address of
the dsl router - or else no internet!

In linux, you configure the network card(s) with ifconfig, but without
knowing which distro you use it's a little hard to tell you exactly what
you need to do to make it permanent...

ObBTW : WHY do you want different IP addresses ?
There's absolutely no need to...you'll only ever run ONE OS at a time!

And another: HOW did you set up your network if you don't KNOW how to set up
IP addresses ?

If the addresses are static then YOU have assigned those addresses - there's
no other way.

Yes. Have even done it "live" on adsl without a router but changed both
to have the same "real" ip as it became too confusing as to what was the
"real" ip for the computer.

As you have a router, just set win & linux with static ips as the router
should have a "static" ip range; if not, then just go into win registery
and change the "last ip" &/or the "request ip" under dhcp.

Thanks everyone, that did it. I forgot about ifconfig; I set it all up so
long ago and haven't needed to touch it since.
