Mandrake 9 networking

By Elomis ·
A couple of times I've given Mandrake 9 a whirl on my PC, and the same problem has arisen each time... and I'm sure we've all been in the situation where we say to ourselves "Ahh, now I remember why that wasn't the solution I went with".

In this situation no matter what network card I install, or how I hunt for why it happens, there is just no software connectivity. When pinging from this host to another I get host unreachable (and they ARE on the same subnet), when pinging from the other host to this it simply times out. Is there a hidden "I know you've plugged it all in, and switched it on, but it won't work till you push this button" switch? I think maybe iptables or some software firewall has something to do with it but I could bewrong....

What are the IP addresses and what OS is the other machine(s) running. If its windows you have to think of Samba before much happens Though Ping should work if your domains are set etc.

The questions says that I CANNOT ping, so saying that "ping should work fine" isn't helpful, it's a comment.

Ok, let's go. I will try to point you out certain steps that you'll have to follow, as there are no many details given(everything hapens using shell):
1. you shoud check using lsmod if the module of your nic is loaded. There are no many chances to be directly compiled into kernel.
2 check if your nic is up and running using ifconfig. if you see there something like eth0 Hwaddress followed by some numbers : separated and ip: aaa.bbb.ccc.ddd like, it seems that your nic is ready to be used.
3.ping your ip address. If you receive echo (64 octets from "your ip": icmp_seq=0 ttl=64 time=0.2 ms) it looks like you are on the good track. Your computer is ready for network.
4. try to see your routing table by "route -n". you will have to see like a table with "Destination Gateway Genmask ... Iface". the first line should show you: your network's ip, 0.0.0.0, 255.255.255.0 and in the last column eth0. The last line in this table should be something like: 0.0.0.0, your network's gatemay's ip, 0.0.0.0, eth0.

If you can see all the following but cannot ping any other computer on the net, check to see if the firewall is not up and blocking you from accessing/being accessed the network. It is common to leave the install on default; thisway, you will have by default your firewall activated.

To deactivate your firewall, go to the Controll Center and in the Network section deselect de firewall.

Hope all these have helped you.
Good luck.
Valentin

NIC is up, module is loaded, IP address doesn't ping, this is written in the question. Firewall is off, routing tables are fine, cards work ok under Windows (PC is dual-boot). Cards are known to work fine under mandrake normally.
