[gentoo-user] spoof mac address

[gentoo-user] spoof mac address

[Joseph]

Does anybody know how to spoof mac address on Gentoo?

I want to connect a machine directly to the modem but if I do so my static IP will change; so to retain static IP I want to spoof mac address on one of my machine to 
the same MAC as on my router.

I don't have access to a Gentoo box atm. But there is an option in /etc/conf.d/net for this.
Check the net.example file.

mac_eth0="00:11:22:33:44:55"

You will also need to set up PPPoE with username and password for 
authenticating on your ISP's radius server, unless your modem is in half-
bridge mode.

Yes, that is what I did:

# ifconfig net0 down
# ifconfig net0 hw ether 00:21:5A:9B:00:F2
# ifconfig net0 up

Now how to reset to the original mac address, without restarting.

If you have a host and a router with the same MAC address, how do you
suppose ethernet will continue to work?

Instead, rather do it right - your modem has a dhcp server. Configure it
to supply a specific address to your host's MAC address. Or, just set
the address statically in /etc/conf.d/net and don't use dhcp.

Or, do you actually want to bridge the modem and do pppoe on the host
instead of by the modem?

in /etc/conf.c/net:

mac_key_001122334455="s:foobar"

documented in /usr/share/doc/netifrc*/net.example.bz2

If you use a different network manager, consult that packages own docs
on how to change mac addresses.

Re: [gentoo-user] spoof mac address

My connection to my provider is kind of slow, so they suggested I connect one of the box directly to the cable modem.
Since I have a dynamic IP (that hardly ever changes), I'll disconnect the router and configure one of my box to the same mac address has router eth0 has and connect it to 
the mode.
This should ensure that my IP will not change.

All I want to do is to run a test speed from: testmy.net

You would normally also need to authenticate onto your ISP's network, a 
function previously performed by the modem.  Unless you connect a router 
behind the modem to do the PPPoE authentication you will need to do this at 
the PC.

There is a possibility that you will pick up a new IP address if your 
connection resync's.

I will be *really* surprised if you see a difference in speed in any way 
attributable to the change you want to implement at the modem.

I just changed the MAC and I got the same IP from the shaw modem but you are correct the speed did not improved I got only 4Mbps down.

Re: [gentoo-user] spoof mac address

[Joseph]

I forgot to mention.
My router is an old 486-box running freesco. So I'm trying to find out if the router is the problem with slow connection.
as my download speed on cable is only 3.7Mbps and it should be about 15Mbps up to 25Mbps
upload speed is 1.5Mbps

What speed NIC do you have in that 486?

10M? 100M? And is it running full duplex?

3.7M is, IIRC, about what I'd expect from 10M half-duplex. NIC cards of
that era were prone to getting auto-negotiation badly wrong.
Even an old 486 should be able to deal with 100M traffic easily.

Even so, I'd still not trust your cable provider's advice. There is
still a good chance the problem really is with the cable connection.

I called shaw tech.support and we did all kind of testing, with box connected directly to the modem (by-passing the router); no difference.
So they've scheduled technician to test it, they suspect it could be a modem itself.
