Destination Host Unreacheable
 

Hi, please need help with getting a nic working:
I installed mandrake 9.1 in a new pc and seems working great but the connection to lan with realtek 8139 chip netword card .

No iptables running, security low, and everytime I ping another mandrake machine I get Destination Host Unreacheable, I boot with knoppix and the nic works just fine (log in with ssh in another machine).

Something is going wrong , this is the end of `dmesg` and it just looks bad:

8139too Fast Ethernet driver 0.9.26
eth0: RealTek RTL8139 Fast Ethernet at 0xce89e000, 00:e0:7d:b6:65:ba, IRQ 17

If anyone can help I just would be very happy to learn why this weird thing is happening.
Another clue is that netconf hangs when trying to configure, but the result of lots of
ifconfig eth0 $ip netmask $mask
/etc/init.d/network start|restart|stop
is Destination host unreacheable

Thanks in advance.

Do you have anything in /etc/network/interfaces? You should have something like what I've got:

# The loopback interface
auto lo eth0
iface lo inet loopback

iface eth0 inet static
address 192.168.0.1
network 192.168.0.0
netmask 255.255.255.0

I assume you're running a class "C" network.

yes i have, in mandrake is ifcg-eth0 but it's nearly the same

have ip, have netmask, etc

I can ping eth0 and lo with success
but no others

thanks for the reply from spain.

Could you run ifconfig eth0 for me? Also, can you ping your external IP? Is this computer running as a router or just a slave?

#ifconfig

I told u i can ping eth0

ping -c1 192.168.1.200
PING 192.168.1.200 (192.168.1.200) 56(84) bytes of data.
64 bytes from 192.18.1.200: icmp_seq=1 ttl=64 time=0.033 ms

as a result 0% packet loss.

This computer now is just slave, running ciertain free software over apache+perl+mysql but without network it just does not worth a dime.

Thanks for the replay. Ask any information u need.

I don't suppose there is a dhcp server on that network is there? If so type dhclient and that should fix it. If not, have a look at the output of route. Post that here. In said output see what it says under the gateway setting for your nework (which should be 192.168.0.0).

the motherboard gigabite with sis650 chipset has onboard lan realtek 8100lb but I just disabled in bios. The situation was just the same, I put a nic realtek 8139 to see if things get better but just stays the same.

If I change the card from the pci slot it just change the irq but the problem is the same.

No dhcp server, only 2 computers running linux mandrake 9.1

#route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo

No need of gateway cos only want to connect 2 pc to see the webpage that this one serves (nogui, but lots of lynx, D:)
have u think of a web server without network connection?

Thanks

It seems that I'm not the only one with this problem.

Problem solved see:

http://www.mail-archive.com/cooker@l.../msg77612.html

simply add option kernel noapic

now it works.

Thanks to adz.
