Internal Networking Question

WindowsDependant · 02-23-2006, 06:42 PM

This is probably an easy one for u guys. I am running a dual boot machine (Win XP Professional/Suse 10).

One thing that struck me as strange is that while under Suse if I "ifconfig", it identifies my internal ip as 192.168.1.101...

but when I "ipconfig" from Windows, my internal ip comes back as 192.168.1.100. What Gives?

Is this a setting in my router that I need to switch, or maybe on my machine itself?

Also I am behind a Linksys Wireless Router.

Thanks for comments and replies in advance

I'm just guessing, but most IP's are checked out for a specific amount of time when you use DHCP. So if you booted first into windows, it may have collected the .100 IP address. Then when you rebooted, the DHCP server noted that the IP .100 was already reserved and to give you .101 for Suse.

On my linksys router I can define static DHCP addresses by putting in the MAC address of the card and then an IP. Then the DHCP server will always give my machine the same IP, regardless of which OS I'm booting into.

Aah I see, that sounds very plausible. Is there a command to tell me the mac address of the machine I'm on, and i'll sure give it a shot.

Yeah, ifconfig (usually as root). Or from windows ipconfig /all. It should be a 12 digit number (two digits/letters separated by :'s on linux and -'s on windows).

Linux XX:XX:XX:XX:XX:XX
Windows XX-XX-XX-XX-XX-XX
