beginning interface eth0 : device eth0 has different MAC address to expected.FAILED


I've noticed on startup of Linux that beginning interface eth0 : device eth0 has different Mac address to expected .. Ignoring : failed

Im running a dual OS startup with linux being the primary start-up and Windows 7 ultimate being secondary. I'm unsure as to why this error is occuring.

I've been told that :

"LAN network interface hasnt been detected correctly. The only network interface you have available under Linux is the loopback adapter, which is just a software interface that Linux provides by default and unfortunately cant be used for licensing.

There are a number of reasons why the the card might not be detected.

Firstly, some laptops disable the LAN interface when the machine is running on battery. If this is the case, plugging the machine into mains and rebooting Linux should fix it. You can probably fix this permanently by changing a BIOS setting.

Secondly, perhaps the card isn't being detected by Linux at all. "

Ive tried to plug the charger in before start-up and also plug the network cable in before start-up; both to no avail.

This is becoming a big issue as the software I need for my seismic interpretation (Traptester) uses a license.dat file that has a hostID defined in the script. Meaning I cannot use this software unless linux can detect my network.

Also upon querying within traptester I was returned the following messages:


"The FLEXnet host Id of this machine is 000000000"

"Link encap : local loopback
>>> Inet addr: 127.0.0.1 mask:255.0.0.0
>>> Inter addr: ::1/128 scope:host
>>> UP LOOPBACK RUNNING MTU:16436 metric: 1 Ex packets:1819 errors:0

>>> overruns:0 carrier:0
>>> Collisions:0 txqueuelen:0

"$FAP_SCRIPTS/lic_req -display :0.0

Getting version ... 6.043
Getting host-name ... Localhost.localdomaib Getting host-Id ... 000000000000
"

Also another interesting issue is the fact that Windows 7 ultimate will detect my network if I start-up with this.

Could someone please help me resolve this issue.

Cheers,

Petar

hmm... I may not have the right answer for you, but I have some ideas you could try. but first, a few quick questions: What linus distro are you using? How did you install linux on this machine? You didn't install linux on that hard drive using another machine and then swap the hard drive to that machine, did you?
I have done that before, and it works pretty well, but it does tend to cause network issues because it is still looking for the old machines network interfaces (possibly causing an error like the one you are having). If that is the case, linux might have named your network card eth1 instead of eth0 but not enabled it, try bringing eth1 up (ifconfig eth1 up).
actually, thats all I can think of. I could be totally wrong, but that would be the first thing I would try.
