Re: problem with changing hw address

Re: problem with changing hw address

as you see the eth0 comes up, but network does not work

root@anna-laptop:~# ifdown eth0
ifdown: interface eth0 not configured
root@anna-laptop:~# ifup eth0
root@anna-laptop:~# /etc/init.d/networking stop
* Deconfiguring network interfaces... RTNETLINK answers: No such process
[ OK ]
root@anna-laptop:~# /etc/init.d/networking start
* Configuring network interfaces... [ OK ]
root@anna-laptop:~# ping www.google.de
ping: unknown host www.google.de
root@anna-laptop:~# ifconfig eth0 down
root@anna-laptop:~# ifconfig eth0 up
root@anna-laptop:~# ping www.google.de
ping: unknown host www.google.de

Re: problem with changing hw address

Hi,

so you cannot get any network connection at all? Have you tried knetworkmanager? It is a nice programme (when it works) but it needs a virtually empty /etc/network/interfaces

For your information, mine looks as follows:

Code:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

Back up your own, try this version and call up knetworkmanager to see whether you get a connection.

Still baffled why you want to change your MAC address. As far as I know this is only done for hacking reasons, getting into other people's network who have MAC restrictions, etc. As such it is forum policy not give out any further information - regardless of the reason (I've been at the wrong end of this kind of thing before, too).

However, if you just want to get onto the internet, we'll gladly help you

Hi,
I am not a hacker, but a rather helpless user. in my flat we have a modem access to the net. it only allows one pc to use it. since my boyfriend has his pc almost always turned on, it is his mac number that is accepted. however, sometimes i want to have access to, with my pc. a router would be a solution, but it is only once in a while that i want to use my pc. that is why until now I simulated my boyfriends hw address. with kubuntu 7.10 apparently the user does not have this freedom any more. So either we put in a router, which then has to run all the time. or I change back to the old version. I thought that someone could give me some advice to find another way.

Ok. I almost empied the interfaces file. then tried to start knetworkmanager.
it does not start. not even give some (error) message. so maybe there is something broken (even if i leave the mac addr.)
that would mean that even a router could not help

Re: problem with changing hw address

That is strange. What does the command line say when, after a fresh boot, you type

Code:

knetworkmanager

Re: problem with changing hw address

It said: nothing.
but I gave up, and bought a router. (and it works). thank you for the effort. and I still think that it would be good to allow the user to simulate another mac address (in this case).
