dhcp client requests a new address every time

EdoardoC · 02-02-2005, 11:22 AM

I noticed that every time I connect to the company network I get a new fresh IP address from our dhcp server.
I am the only mepis user in the lab, and the only machine that has this behavior is my pc ...
my sysadmin noticed that the dhcp server offered me my old address but my client has refused it and that's why I got a new one every time.

Does anyone knows what may be wrong ?

I am running promepis 2005.b4 fully updated with apt-get till today (kernel 2.6.10, kde 3.3.2 ...).
Netwroking is ethernet 100, no wireless.

Sounds like a security feature rather than a "bug"/problem. Is there some particular reason why this is not acceptable?

it's annoying that other machines can't rely on mine having a constant IP.
well the sysadmin now grabbed my mac address and has overcome the problem by force, still I'd like to understand what setting is wring so that I may be able to fix things gracefully

Why should any machine depend on yours having a static IP, unless it is acting as a server of some sort? Even so, a good DHCP setup can setup a dynamic DNS system as well.

right...ddns interim works great on this. Your sysadmin should give it a try..

--that's the nature of dhcp... the argument defeats itself -- if you need a static IP, use that, you shouldn't be trying to pretend a dnamic IP is static, anyways...

I understand some objections on the usefulness of keeping the IP
still, the lease settings normally allow anyone to get a random IP *the first time* they conect to a netwrok,
and then on they typically keep getting the same one day after day.

why am I different ;-) ?
I think it must be some client setting but so far no-one has come up with an answer, and my sysadmin has tied one IP to my MAC address - it just wasn't necessary with the other clients.
