ext2 and ext3 are file systems that Linux uses.

Did you try ifconfig eth0 up as root.

Do you have a spare network card laying around you could try.

Yes I did, no errors this time, but no change in ping results though

Unfortunately I don't

Just to be sure, I blew out the case, rechecked all the cables, re-checked the router recognition, all seems fine.

I dont know. I have run out of ideas.

Is your Linux box getting an IP address from your Router or do you have it statically assigned.

does your ifconfig look something like this.

eth0 Link encap:Ethernet HWaddr 00:50:BA:4A:52:F5
inet addr:192.168.0.22 Bcast:192.168.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2358153 errors:2 dropped:0 overruns:0 frame:0
TX packets:2153598 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:1339048833 (1277.0 Mb) TX bytes:1094222401 (1043.5 Mb)
Interrupt:11 Base address:0xd000

THis part is definately different:
RX packets:2358153 errors:2 dropped:0 overruns:0 frame:0
TX packets:2153598

I show RX packets:0
TX packets:230



PS I have to run, I'll check this when I get home.

Thanks for your effort!

John      4080  4067  0 12
:03 pts/1    00:00:00 egrep dhcp 
ifconfig output

PHP Code:

You can do the ping with the -c option:
ping -c4 localhost will ping the loopback device 4 times.
I didnt see this mentioned, but, do you have an entry for the loopback in /etc/hosts?:
127.0.0.1 localhost
Try the command ifup eth0 as root.
I had a similiar problem once and fixed it by moving the nic to another slot.

Network unreachable
eth0 initialization failed



I could try another slot later if you think that's a good next step.

Doesn't look like the machine even recognizes the network card. You are not getting anything from ifconfig for the network card. Have you tried another card or tested that card in another machine.

Hi

I haven't had time to pick up another card yet. May try getting one tonight. I have not tried the card in another machine yet either. I hate to risk screwing up another connection on the network, so I think I'll try a new slot and/or new card!

Finally some closure on this!
I had to re-boot my Windoze sys again, so I decided to finally move the network card. I couldn't get the Cat 5 out so I just decided to re-seat it.
Voila! It gave me some errors, then ran through some processes and came up and I was able to get back online!
I can't see it in my network neighborhood at the moment, but I think I need to start something again to be seen in my LAN, right?

Thanks for all your patient help here, not sure why this didn't work earlier.

John
