Will ics lease an ip to a linux box?

I don't know just what ICS is, but if it uses DHCP, then yes, it should lease an IP to a Linux box - Linux supports the use of DHCP. Check your system documentation.

I remember now - ICS is Windows Internet Connection Sharing. I don't know quite how it works, but again, if it uses DHCP...

If not, you could reverse the setup and use the Linux server as a NAT firewall - it would share the IP with all machines connected behind it transparently.

Makeing the linux box the firewall/Nat is my final solution but i am a linux novice and will take time to set up in the meantime i want the linux to have access to internet while i familairize myself with it. AND ICS has like no documentation to speak of.

ics doesn't lease IPs - this is NAT and nothing more. you need to have static addresses or DHCP server. but be carefull with default gateway because ics needs this configured, otherwise your packets for internet won't reach ics machine.

I need to know if teh problem is in the linux box or not. Win9x machines all get thier ip's from the ICS nat service fine.

Internet Connection Shareing doesn't seem to have a hell of alot of documentation. but in the reg I've found what look like routing tables for common games. So it seems to have the ability of a full fledged Dhcp? But my question is Still the same. Why won't it lease/issue an ip to the linux box?

hmm... I've checked MS documentation. It's like there is two scenarious. With auto-configuring and without it. Check ICSRM.TXT file from Windows 98 SE, also support.microsoft.com/support/kb/articles/Q234/8/15.ASP and support.microsoft.com/support/kb/articles/Q220/8/74.ASP
I don't know if your Win98 PCs using DHCP or APIPA. there is some info at support.microsoft.com/support/kb/articles/Q238/1/35.ASP how to turn DHCP server on.
i think I'll write static address in linux box in your case and forget about this problem :)

ICS is not a true DHCP but a very crippled version (a baby DHCP server if you will) that assigns the ICS server an address of 192.168.0.1 and all ICS clients get an IP in a range from 192.168.0.2 - 192.168.0.254 with a subnet mask 255.255.255.0. Allclient boxes that use it must have ICS enabled and DHCP as well. Since, to my knowledge, Linux does not support this service you will be unable to use Linux as a client box. However, you can use Linux as the proxy/router for the Window's boxes. So Irecommend that you think about reversing the roles of the Windows and Linux boxes.

Um i have set ics to issue 10.X.X.X series and the clients do not need ics installed. But yes linux should be the nat/dhcp server. I will get to that but in the mean time...
