Network is unreachable

[PaulClarke]

Hello,

I have just purchased a new laptop - a Pioneer and installed FC4 but the lan connection will not work. I have used my old laptop to check and the system is fine. On booting up the eth0 failed to get an IP address and if you try to ping the gateway you get a "Network is unreachable" error. In the network Configuration screen the eth0 is Inactive when you try to activate it the attempt fails.

Any ideas?

Regards

Paul

Please let us see the output of cat /etc/sysconfig/network-scripts/ifcfg-eth0

Hello,

Thank you for your response

The file reads:

DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:40:d0:7b:25:2e
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=yes
IPV6INIT=no
NETMASK=255-255-255-0
IPADDR=192-168-0-056
GATEWAY=192-168-0-1

end

I think the last three lines are my poor attempt at a set IP address which did not work.

Again thank you

Paul

Hello,
I changed the "-" to "." and the eth0 will now activate but the ping still fails.

I changed the "-" to "."

Did you change all of the last three lines? Also, you needn't specify an IP address if you use DHCP. Please eliminate the line IPADDR.

Then, as su - (not just su), do service network restart. You should be able to then do ifconfig eth0 and see an IP address...and ping!

Let us know.

Hello,

No that did not work. When I did a ifconfig eth0 I rxed the following
Link necap:ethernet HWaddr 00:40:D0: 7B: 25: 2E
inet6 addr: fe80::240d0ff:fe7b:252e/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:5 base address:0xa000

I don'y know a lot about this but it looks like it sending a great deal?

Let's try /sbin/dhclient eth0. If it appears successful, do ifconfig eth0 again and see if you got an IP address.

TX packets:0 tells us it's not sending at all.

Hello,

I tried a solution from another threat and by putting a comment in the grub loader file the system worked (last night).

Thank you for your response

What thread is that? I'd like to see it.

Hello,

I cannot see it now but here is the email I recieved from the most helpful fellow that got my laptop working

Here is my /boot/grub/grub.conf
Code:

title Fedora Core (2.6.12-1.1447_FC4) root (hd0,0) kernel /vmlinuz-2.6.12-1.1447_FC4 ro root=/dev/VolGroup00/LogVol00 acpi=ht psmouse.proto=exps initrd /initrd-2.6.12-1.1447_FC4.img



hope this helps...

It is the acpi=ht that appears to have done the trick
