I recently updated to Windows XP and have run into a few problems setting up my network so that XP can communicate with my Linux box.

I dual boot Linux with Win98. Win98 pulls the IP of 192.168.1.2.

I have a Linksys Etherfast Cable/DSL Router with DHCP turned off.
Here is what I have done so far.

1. I boot up Linux, and I check DrakConf. Linux is set to pull a static IP of 192.168.1.4.

2. I ping the router at 192.168.1.1 and get a response.

3. I ping my WindowsXP machine at 192.168.1.3 and get a response.

4. I try the reverse from WindowsXP and I get a "request timed out" error when trying to ping Linux.

5. I also have an Apache server set up on Linux, and I can view the server from WinXP by typing in "http://192.168.1.4/"

I would appreciate solving this one on my own, so just a few pointers are all I'm looking for.

Thanks for taking the time to read this

I don't know how relevent or helpful this is, but here is the output from...

Do you have a firewall installed?

On the linux box:

Yes I have firewall installed. I don't know how to remove it, so I tried to allow everything.

Here is the output from that command:

Thanks again for your time.

to stop your firewall try
don't know what distro you have ...

Ok thanks. I'll try that right away. Sorry I didn't include it earlier. I am running Mandrake 8.0

Does it work by now? Or do you still need help?

I ran that command and tried pinging my linux box again but received the same message. When I searched the forums for a similiar problem. I saw something about ICMP rejecting ping requests? If the firewall is off, it can't be the culprit, can it?

I just tried to telnet to my linux box from windows. It gave me the following error message:

"Could not open connection to the host, on port 23.
A connection attempt failed because the connected party did not properly respond
after a period of time, or established connection failed because connected host
has failed to respond."

Would I be right in thinking that that means Linux is not getting the request?

Alright I finally got XP to ping Linux. In case it might be helpful to anyone else, here is what I did:

--SEARCHED THE INTERNET Always start here!

--Found out some information about inetd (xinetd on my linux box) and then looked at the settings in /etc/xinetd.d/.

--Checked network settings in DrakConf and netconf.
I found out that the network driver in netconf did not match te one in DrakConf. hmmmmm. In DrakConf it chose natsemi, the universal one. In netconf, I had set it to rtl8139 (for Netgear FA311 Fast Ethernet PCI card).

--Checked iptables again (in /etc/rc.d/init.d/) and made sure it was off.

--Tried pinging again, and Voila!

Thanks a bunch for all the help from markus1982.

No problem
