I’m not very good in c, know little bit only. If I want to change the coding to give ipaddress base on the Computer name (not base on MAC) which palce do I have to change?

Thanks,

Sajith

no, as far as I know there is no way of doing this on the client side. There are some configuration APIs on the client side, but nothing similar to the callout APIs on server side.

I have a specific problme i need helo with.

On my network somebody activates second dhcp server (unknowingly i suppose) on random times. When it happens all my PC’s with automatic settings get bad tcp/ip settings and wont be avaiable on the newtork.

I cannot add any new hardvare (e.g. make private network inside existing one) so i need a way to “convinse” XP SP2 machines *not* to accept settings from any other DHCP but mine.

Is there a way to do this!?

TIA, ChupaChu!

Sounds like your setup is much more streamlined than mine.
I do capture login data (although not with Kixtart) but my problem is twofold: 50% of the network are Apple OSX machines. This means that I need two of most everything for network management. The OSX buildings also were not under any sort of centralized management until recently (separate passwords, etc.)
The second problem is that this network is for a K-12 school district. Very poliiticized. Their motto seems to be that it’s better to let 100 bad guys onto the network than cause grief to one school administrator. So I need to err on the side of caution with this.
We do have an excellent firewall which logs all activity inbound and outbound. If someone is hogging network bandwidth, I can find out who they are and stop them. Usually it’s a computer that doesn’t belong to the school district. Being able to deny that computer an ip address would make my life much simpler.
I agree that a MAC address whitelist would be the way to go if I had administration support. That isn’t the case here.

I run a smaller system, but found I had two sources of legatimate MAC address. We use KixTart for logon batches. I’ve had it setup to log some basic information, including MAC addresses, for years. We also use PC-Duo (Vector Networks) to inventory our hardware. Current MAC addresses can be extracted from it’s database and probabily from other similar tools.

Oliver,

I’m glad to hear you’re going back to work on MACkerer2. Windows 2007 and it’s DHCP server will be with us soon. Thanks for your efforts.

Colin

no this, is currently not possible, but after the interest in MACkerer2 increased, I decided to pick up development again and would include this option. However, this is going to take a while.

I just converted the project on Monday for my current compiler.

Very nice job with this. I set it up and was able to use it in only a few minutes. Very detailed logging even if there were no other uses.
Is there a way to create a blacklist of MAC addresses that I want to deny access to as opposed to registering all MAC addresses that I want to grant access to? The network I work with has 15K+ computers and it would be next to impossible to keep a current list of MACs. I could update a list of known bad MACs that I want to keep out.

GUI frontend?
