promiscuous networking


This might be better in the networking forum but since I'm using debian maybe I'll get a better answer here


promiscuous setting of the netcard - how do I activate that?

I want to change my MAC (or at least what it reports) (rotate) so that I can get more IP's on one interface. The reason is that my ISP has a proxy that limits the amount of data/machine/day.

So, I installed rarpd in order to find valid ip-MAC pairings, but I don't know how could I activate and use this data for promiscuous networking?

I don't think anyone here will help you try to violate your agreement with your ISP.

Why not just contact your ISP and tell them you need to download more data / day than their proxy allows? Maybe they're willing to be flexible.

Wink no violation

There was no signed document about the Internet connection!

And my ISP offers for free his services.

The problem is that he is an odd guy who can't seem to understand that 1.2Megs/day is insufficient.

After more monitoring I saw that the limit is for certain files (eg. .gz .avi .zip .rar .mp3). I have reached this conlusion as my deb files come through at constant rates of 5 to 15kbs.

So I have a workaround since I need this raise in traffic for updates and debs:

How can I instruct apt to get the Package file instead of the Package.gz file?

Is it possible?



The promiscuous question remains, in case my ISP blocks deb files too and for my own knowledge.

And another thing, since this is supported why shouldn't it be used, even if it used for didactical purpouses?

Za! Ouch. Last night I did an apt-get dist-upgrade (on dialup) and it was 56 MB. Sounds like you might need to find a new ISP.

The way I've always understood it, you can't change your MAC address for an ethernet card -- it's set at the factory. I guess you're asking about dialup. Sounds like a cool idea. Let us know if you figure out how to do it.

Finally, regarding your sig, note the unfortunate news:

Question so It can't be done for eth?

I was wondering since is clear that the MAC is physically there and we have the kern that reports it, and we have the kern sources, we might report whatever we want !!!!

Or, even better :

the real netcard goes through a loop-like device that behaves like the NIC but reports MAC on other rules.

So I will have something like

apps - NIC - virtual card - ISP

but using the physical layer of the NIC

I doubt if you manage to make a second MAC address appear after the first one you get assigned another IP address by the DHCPD cuz the MAC addy needs to be auth'ed by your ISP.

Besides that, the more traffic on the LAN, the more it will adversely affect throughput for all of the LAN users as it's a shared medium.

Question

What if I enable the virtual eth first and give it the real MAC and then I enable the real eth . (I mean in the init.d)?
