I have tried to get to work an SiS900 and afterwards a Realtek 8139 card with my newly-installed Mandrake 9.1
Since both network cards basically give the same errors, I assume I am doing something wrong with the configuration.
If I select for the card to get an IP number via DHCP, the "network assistant" program crashes (freezes, no error message). If I choose a static IP, the assistant says everything is ok. The output I get from ifcfg also looks like the card is set up.
However, it is not possible for me to ping other machines in the local network (or to connect to the internet via the router).
Since I am quite sure my settings (gateway etc.) are correct -- are there any other settings apart from those in the "network assistant" which are important to get the network going?
Copying the whole ifconfig output by hand would take a little long, but here's what seems important to me:
eth0:
inet Address: 192.168.1.35 bcast Address: 192.168.1.255 mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU 1500 METRIC 1
RX PACKETS: 0 etc.
TX PACKETS: 0 etc.
Farther down there's
lo:
Protocol: Local Loop
LOOPBACK RUNNING
etc.
If there's anything suspicious to me in the output, it is that bcast address - but only because I don't know what that is supposed to be and I didn't enter it anywhere.
Is the card an ISA bus or PCI bus card? I had all sorts of trouble getting ISA bus cards working in RH8 installations and eventually found that what it really wanted was a PCI bus card (3com 3c5xx etc etc). Something to do with confilcts between ISA and PCI. Life's too short to try and figure it out!
Also check that all your machines are running or trying to run in the same subnet (ie 192.168.1.x/255.255.255.0 in your case). That got me too :-}
Do you have other machines connecting via the same DHCP server? If so, you know it works. Bizarrely I had a problem with a Realtek DSL router that was acting as a DHCP server on my net where if I hard coded the ip address the pc wouldn't connect, but was OK under DHCP. Realtek now consigned to the other side of the firewall and using a passive hub on the inbound side. DHCP is from another machine, and everything OK.
