I have installed Mandrake Linux 9.1 on a LAPTOP with a "NIC Fast Ethernet PCI Realtek RTL8139 Family" card. The system recognizes it, automatically selects the module (8139too), I think I have configured it properly, but it doesn't work: only the "ping localhost" command works, when I try to ping other addresses on the LAN the answer is "destination host unreacheable".

Ifconfig:
eth0 Link encap:Ethernet HWaddr 00:40:CA:B7:0F:7B

It's not a hub or cable problem, because the LAN works perfectly under Windows, which is also installed on the same computer.
The problem is not the APIC, because it has been disabled.
I'm not running a firewall.

Any help you can offer will be appreciated.

?????????????(Check your firewall rules,......)??????????????????

What is the complete output of

#netstat -nr

You would appear not to have a gateway set.

This is the risult of netstat -nr

Hi!!!
I am Ieee! And I have the very same problem.
Please if can resolve it, please send me an e-mail to alexreguart@yahoo.es and tell me how can I do it, ok?

Thank you very much!

Well, you have a gateway.

Can you post your /etc/resolv.conf file and your /etc/hosts file?

Cheers--

Hi

I have the same problem on my laptop. I cant ping another RH9 box on my lan. My eth0 device is UP.

I have also tried turning the firewall (iptables) off [service iptables stop] and try the ping but still no response.

Any help will be much appreciated.

By the way, I am from Mauritius and my e-mail is jrabbani@intnet.mu.

What IP are you trying to ping?

When you run "mii-tool", what is the output?

-Mag

I have been having a similar problem and have gone thru all the info I can find. Last night I asked a friend and he said the only thing that probably is doing it for me is the local net might not allow Unix/Linux packet travel for secure reasons. As such how would i set up my packets to look like windows packets instead of linux packets?

/etc/resolv.conf
nameserver 192.168.0.200

# ppp temp entry


/etc/hosts
127.0.0.1 localhost
192.168.0.1 fabrizio
192.168.0.10 velda
192.168.0.16 enrico
192.168.0.4 marco


mii-tool -v

I try to ping the IPs on my lan (192.168.0.X), but it's like the cable is unplugged...

what does /etc/sysconfig/hwconf say about the Ethernet Card? Is the IP Address static?

Perhaps 8139too is not the exact driver match for your NIC.

Which Kernel have you installed?

You can try to update it to the 2.4.21, probably this will resolve the problem.

Bye!

It's always a good idea to do

iptables --list

to see if you really have turned off your firewall, alot of people get caught out, not saying any of you have but it's another check you can do.

And also

cat /proc/sys/ipv4/icmp_echo_ignore_all
you want the output to be zero

If you're only trying to ping other machines on the exact same subnet having a gateway set is irrelevant so that shouldn't be the problem

Windows packets and Linux packets ?

/etc/sysconfig/hwconf doesn't exist (the hwconf file doesn't exist at all).
The kernel is already 2.4.21
iptables doesn't exist neither as command nor as file.
cat /proc/sys/ipv4/icmp_echo_ignore_all says that there is no such file (anyway I'm sure that the firewall is OFF).

I don't think the problem is linux or windows packets, because another machine on the same LAN which has both linux and windows on, works perfectly with the two of them.

I really don't have a clue...

Ok, if you're positive there are no firewall rules then it's irrelevant but

you have to be route to use the iptables command

and I missed a bit out in the path

cat /proc/sys/net/ipv4/icmp_echo_ignore_all (which is irrelevant as you can ping localhost so forget it)

You can ping 192.168.0.16 (the ip at the start of the thread) aswell as localhost?

If card is working
Everything is on the same subnet
No firewall rules

maybe try a different cable?
