many of us are dual booting linux and windows right?

Well I have an adsl connection with a static IP... I logged into windows, released IP using IPconfig, booted into Mandrake, and Mandrake gets the IP from DHCP...

Now my problem:
How can I release the IP from Linux?
I used the ifdown eth0 but when I booted into Windows I had a blocked IP...
I need a way to release my IP from Linux...

Anyone?

thanks

ifdown will remove that ip, not really sure what you're looking for... if you just want to set that static IP within Linux as well as Windows, then try opening the mandrake control center and changing the ethernet type from dhcp to static and enter the details.

There is no reason to "release" the IP if you are maintaining the same connection (e.g. using the same interface) on Windows as you do in Linux.

ISP's allocate IP's based upon the mac address of the connecting interface.

Since the MAC remains the same under both OS's, each you get back the same IP and work w/o forcing you to re-init the modem.

I do this all the time.

well yes, that's normally the logic. but if it's not working it's not working.... and the MAC presumably isn't being involved if the guy's literally got an IP on a piece of paper...

I agree, since it's a static IP, don't use the DHCP, just enter the same IP address for both windows and linux manually. I've had mine setup that way for years since windows and linux aren't running at the same time (running vmware is a different story).

OK... I used the ifdown eth0 command in Linux yesterday (before reading your posts)...
Booted into windows and set the Ip manually... Now i am trying to boot into linux but there is no GUI...
Reboot...
Mandrake booting, ESC in verbose mode... THere seems to be problem...

It says
bringing up interface eth0 [ok]
bringing up interface ppp0 [failed]
assigning raw devices: cannot open master raw device "/dev/rawctl (no such device)
...
..

Starting ADSL .......

And it boots into terminal...
There seems to be a problem here... I typed init 5 but nothing happens

SOlved it...
The problem wasn't at the ADSL... But with nvidia drivers...
I used the startx command and i realised that the error wasn't with the adsl service but the nvidia drivers weren't initializing... CHecked the logs that gave me, and in the I had to change an entry in /etc/modprobe.preload ... via-agp had to be renamed into nvidia... That solved it... Now I see the Nvidia logo when madrake starts...
tHanks for your help
