Networking Windows and Linux

    Okay, after a lot of mind-numbingly tedious work, I've managed to get my home network working with 1 exception. At home, I've got 2 windows pcs and 1 linux pc on a BNC network. The windows PCs can ping/fileshare/etc no problems. The linux pc can ping both Windows PCs , but neither windows pc can ping the linux PC - let alone anything else.

    Does anyone know why this would happen?

    OS ---- IP --- Subnet
    Windows 98se ---- 192.168.1.2 ---- 255.255.255.0
    Windows XP ---- 192.168.1.1 ---- 255.255.255.0
    Linux (Man. 8) ---- 192.168.1.3 ---- 255.255.255.0

    The windows PCs are on the workgroup 'Workgroup', although Linux has no workgroup specified (can't find anywhere to put it).

    Have you got a firewall on the linux box? You can set it up to not respond to ICMP packets (so ping won't work).

    You can use samba to let the windows pcs connect for file sharing.

    The pre-installed mandrake firewall is installed, but as far as i can tell its set to allow everything.

    Put WG in samba.conf or use the samba browser to do this. Have a look in Linux conf / networking. Lots of options there and more likely to be a problem with that. Had same problem but resolved with linux conf as far as I can rember. Try and dig it out if no one posts answer before me.

    You just contradicted yourself here, can the windows PC's ping or not ?

    Try running tcpdump on the linux machine while pinging from the windows machine,
    and see what happens.
    You should see something _like_ this...

    fred# tcpdump -i eth0 icmp
    tcpdump: listening on eth0

    02:04:00.164090 192.168.1.2 > 192.168.1.3: icmp: echo request (DF)
    02:04:00.164167 192.168.1.3 > 192.168.1.2: icmp: echo reply (DF)

    I'm guessing some sort of firewalling thang on the linux machine...

    Thanks for all the input guys, just in case anyone has a similar experience in future and decides to trawl through this forum, I fixed it by:

    ifconfig eth0 down; rmmod 3c59x
    insmod 3c59x options=0x0203
    ifconfig eth0 192.168.1.3 netmask 255.255.255.0


    The card is a 3com combi 10/100mb pci card.
