Public bug reported:
I have an ASUS Mobo (P5N32-E SLI), Intel Q6600 multiboot rig with
several older versions/flavours of Ubuntu plus XP/Vista installed and
mostly working.Unfortunately I just wiped my 64bit version of Ubuntu to
install 9.04 and now I'm regretting it.
I believe that the NIC controller is an nVidea MCP55
I have long awaited 9.04 and in anticipation of great things ( to
replace M$ once and for all) downloaded both 32bit and 64 bit versions
of Ubuntu, Mythbuntu and Xubuntu....but unfortunately I can't get any of
them to see the Net so I'm stuck.
I'm not exactly a newbie to UNIX as I have vintage experience of
Solaris,AIX, HPUX etc but have only dabbled with Ubuntu.
However, unlike some other muppets I have first checlked that the NIC is
connected (properly) and active (as seen from a Linksys Switch) etc. All
is well and as you can see I have other it on this LAN that I can get
out to the Net on over DSL.
Symptoms of this problem seem to point to a config or timeout problem
Network Manager (don't know the pkg name sorry) Applet 0.7.0.100).
Having trawled forums for a fix I have tried things like editing
/etc/network/interfaces and here's a curious thing .... as soon as you modify
/etc/network/interfaces
1) Network Manager disables itself.
2) Networm Manager still ignores whatever Mask you enter and sticks with
255.255.255.255.
I have also tried adding nameserver entry (for 192.168.1.254) in
resolv.conf and that makes no difference.
In my working copy of Kubuntu 8.04 (kernel 2.6.24-16) DHCP works fine
with /etc/network/interfaces as per default (auto lo // iface lo inet
loopback) but with resolv.conf set to: search lan // nameserver
192.168.1.254, for which it obtains the address 192.168.1.80.
Even if I manually change the setting in Network Manager for the
interface (eth0) from 'Method' - 'Auto (DHCP)' to 'Auto (DHCP) Address
only) and also change 'Routes' to '192.168.1.0 255.255.255.0
192.168.1.254 ' - DHCP still fails.
'sudo dhclient eth0' >:
....
Listening on LPD/eth0/<correct mac addr>
Sending on on LPD/eth0/<correct mac addr>
Sending on Socket/Fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
(line repeated for intervals 10, 7, 17, 8, 15)
No DHCPOFFERS received
No working leases in persistent database - sleeping
sudo dmesg|grep -E 'eth0' >
[ 7.756680] forcedeath 0000:00:11.0: ifname eth0, PHY OUI 0x5043 @ 1, addr
00:1b:fc:65:1a:7d
[ 33.304005] eth0: no IPv6 routers present
...but again.... this is working fine in Kubuntu 8.04.
Also note that:
sudo ifdown eth0 >
ifdown: interface eth0 not configured
sudo ifup eth0
Ignoring unknown interface eth0=eth0
whereas 'ifconfig eth0' ...correctly reports 'eth0' details on <correct
mac address>
The only other curious thing I've seen is that ...
sudo lshw|grep network >
*-network DiSABLED
description: Ethernet interface
physical id: 1
logical name: pan0
serial: fa:8a:30:99:b9:af
etc
....which is the MAC address for eth1...... but there's no entry for
eth0 !??!
lsb_release -rd >
Description: Ubuntu 9.04
Release: 9.04
Note that I get exactly the same behaviour on Mythebuntu/Xubintu 32bit
and 64bit vers.
Please advise a fix for this as I cannot find any coherent answer or bug fix
elsewhere.
