network stopped working in linux, ok in XP?


I'm running mandrake 9.1 and use dhcp for ip assigning (at boot-up).
This has worked perfectly untill i went on vacation a few weeks ago. When i came back the networking had stopped working in linux. It is still working perfectly in XP.
The connection is through a residential LAN.

The card is a RealTek RTL8029(AS) PCI.

If I try to ping the gateway I get:
[root@localhost log]# ping 192.168.1.1
connect: Network is unreachable

The output from "route" is:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo

The output from "ifconfig":
eth0 Link encap:Ethernet HWaddr 00:C0:26:11:A6:91
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:135 errors:0 dropped:0 overruns:0 frame:0

TX packets:80 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:5208 (5.0 Kb) TX bytes:5208 (5.0 Kb)

If I try to take the NIC down and up again I get:
[root@localhost log]# ifdown eth0
[root@localhost log]# ifup eth0
Determining IP information for eth0... done.
/sbin/ifup: line 433: 2018 Hangup /etc/init.d/tmdns reload >/dev/null 2>&1


What has gone wrong? It seems to transmit and recieve packets (ifconfig) and yet the network is unreachable? Any suggestions?

my experience

dhclient / dhcpcd && cable modem
Architecture 1 : X86

Question text

I recently had the exact same problem and I\'ve worked my tail
off the last two weeks trying to get Mandrake 9.1 and dhclient / dhcpcd to
work with my cable modem.

I found TONS of people with the exact same problem on the internet using
Google, Mandrake Club, Mandrake Expert, and even Redhat\'s newsgroups. But I
found no answers. So now that I have the answer, I want it spread FAR AND
WIDE so that no one goes through the hell that I just went through.

My problem was very well described by others especially:

http://www.mandrakeclub.com/modules....Forum&file=vie
wtopic&topic=7486&forum=10

and

http://www.mandrakeclub.com/modules....Forum&file=vie
wtopic&topic=7486&forum=10

and

http://www.mandrakeexpert.com/showarchive.php?arc=62608


My only additions are as follows: The problem is not fixed by changing
distributions and using Redhat, or Slackware, or Suse. They all have this
problem. It also doesn\'t matter if you use dhclient or dhcpcd or pump.
(Though pump is a little nicer.) They all have this problem.

Secondly it\'s not just Mandrake 9.1 that has the problem. My old box had
Mandrake 6.2 and, although it worked for three years without too many
problems, it often completely hung and crashed when I tried to fetch an IP
from Comcast\'s DHCP server.

So the answer? The answer to my problem was the cable modem. The old model
\"Tail Fin\" aka \"Shark Fin\" aka 3Com POS is not friendly with linux.

My old cable modem had very old firmware and although it is possible to
upgrade firmware, Comcast put a password on the SNMP connection. So that
option was not open to me.

I lease my modem so I had the wife march down to Comcast\'s office and demand,
(she\'s really good at that :-), a new modem. I ordered her to demand either
a Surfboard (Motorola) or any RCA model. Comcast explained that they didn\'t
have any new modems and she had to accept whatever they give her. Secondly
they said that the Surfboard modems won\'t work \"in my area\". No clue why.

Well the wife went off on the creep. And voila. I\'ve got an RCA DCM305
modem and it works. No hitches. No problems.

Please please feel free to email me if you\'ve got this DHCP problem. I can
help.

-Ed.
