dualboot-kubuntu won't connect

[basho]

hi-
can anyone help me sort this out, please.

2 machines on the same network.

we have kubunto "dapper" amd64 version running with NO network problems on one machine-dhcp connection.

the 2nd machine is a dual boot kubuntu + windows 2000 - dhcp connection
on this machine win2000 connects to the internet and shares files with the 1st machine, without problems.

however, kubuntu does not, will not, connect to the network, on the 2nd machine.

-interface file
/etc/network/interfaces

auto lo
iface low inet loopback
address 127.0.0.1
netmask 255.0.0.0

auto eth0
iface eth0 inet dhcp
.
.

When I run: /etc/network/interfaces restart

Listening on LPF/eth0/00:17...........
Sending on LPF/eth0/00:17...........
Sending on Socket/fallback
DHCPDISCOVER (repeated 7x)
No DHCPOFFERS received.
No working leases in persistent database - sleeping

Kubuntu/System Settings/Internet & Network/Network Settings Dialog:

shows eth0 as Enabled w/ dhcp.
however there is no entry under for the gateway.
the Domain Name System says (among other things):

127.0.0.1 localhost nad4400 *
127.0.1.1 nad4400

* (nad4400=machine name)



Can anyone point me in the right direction. I think i've read all the posts relating to this topic.

thank you.

Re: dualboot-kubuntu won't connect

It seems You have problems receiving a dhcp lease on this machine..did You set correct gateway in network settings dialog? Also, did you try to start dhcp from console?

Also, I'd suggest to try setting a static IP and see if it works.

Can You try these and get back with the results?

hi cafeina

"It seems You have problems receiving a dhcp lease on this machine..did You set correct gateway in network settings dialog?"

Yes but they don't seem to persist.
Under DHCP there is no entry for the "Routes" in "Network Settings" in the "automatic configuration". In admin mode, i set the gateway as: 192.168.1.1
when i reopen the network settings dialog the gateway entry is blank.

" Also, did you try to start dhcp from console?"

sudo ip addr flush dev eth0  -Nothing to flush
sudo ip link set eth0 up
sudo /sbin/dhclient eth0
DHCPDISCOVER (tries 5x - No DHCPOFFERS received)


"Also, I'd suggest to try setting a static IP and see if it works."

auto eth0
iface eth0 static
address 192.168.1.15
netmask 255.255.255.0
gateway 192.168.1.1

does not work.

"Can You try these and get back with the results?"
thanks for your help.

Hi,

Can you tell us what message you get in dmesg and /var/log/daemon.log about your eth0 ?

Cheers

Re: dualboot-kubuntu won't connect

hi-
in dmesg, there is only one entry for eth0;
[ 35,400577] eth0; forcedeth.c: subsystem: 010de:bound to 0000.00.10.0

in daemon.log, it is a repeat of the msg. from the console
i.e.
a series of DHCPDISCOVER entries that end with "No DHCPOFFERS received" No leases in persistent database - sleeping.

in udev;
DEVPATH=/class/net/eth0
PHYSDEVPATH=/devices/pci0000:00/0000:00:10.0
PHYSDEVBUS=pci
PHYSDEVDRIVER=forvedeth
INTERFACE=eth0

in syslog:
eth0: forcedeth.c: subsystem: 010de:cb84 bound to 0000:00:10.0

thanks

Re: dualboot-kubuntu won't connect

Hi,

I've read once again the thread, I have few more questions :
- What is your network ? Do you have a routeur or something ?
- How are you getting ip in windows ? Isn't this windows the dhcp server for the two machines ?
If yes, you will need to set on the kubuntu as dhcp to get the same behavious as in w2000.

Cheers

Re: dualboot-kubuntu won't connect

hi
sorry i didn't get back here. i've been playing around with the network. for the time being, i took kubuntu off and installed suse 10.1 (i'm more familiar with the tools in suse). the following is a post to the suse forum (same problems there)

................................
hardware: asus m2n32-sli deluxe with "dual gigabit lan controllers supporting nvidia nforce 590 sli" so the specs say.

eth0: suse + w2k; w2k connects - suse not (static or DHCP)

when i do this
eth0: w2k - connects DHCP
eth1: suse - connects DHCP

on reboot into suse, NetworkManager tries to connect to eth0. when it finishes connecting(??), i switch to eth1 in NetworkManager and suse connects.

it's like w2k "owns" eth0.
.......................

i know this doesn't solve the problem but it seems curious that eth0 seems to be captured.

Re: dualboot-kubuntu won't connect

via the device manager in W2K check the LAN connection and see if
wake on lan is enabled
if its try disabling the wake on lan entry ...

that did it.
by the way, i re-installed kubuntu overlaying the suse and kubuntu had no problem binding to eth1

it now sees both ports and picks eth0.

thanx.
