Hello Alex,<br><br>no you are not dumb. I did a mistake in understanding and sorry for that. The client gets only ONE IP Address but this 590.000 times. So I have a very big log file etc. and the cpu usage is also very high.<br>
<br>Concerning the ip-table proposal:<br><br>Is there a way to ignore a special amount of packets with ip table? I dont want to block all the packets from the client. Can you maybe post an example for IP-Tables?<br><br>thanx a lot,<br>
cheers,<br>Juergen<br><br><br><div class="gmail_quote">2011/2/3 Alex Bligh <span dir="ltr"><<a href="mailto:alex@alex.org.uk">alex@alex.org.uk</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Till somebody powered off the printer the dhcp server got 590.000 dhcp<br>
requests. Of course the pool was empty.<br>

Perhaps I am being a bit dumb here, but if the same device re-requests<br>
an IP address, isn't it going to get the same entry from the pool (assuming<br>
mac address and client-id are the same). If not, can you not segregate<br>
it by assigning it a fixed IP? I am taking it configuring the printer<br>
with a fixed IP is not an option.<br>
<br>
If your dhcp server never needs to talk to the printer at all, you<br>
can just ignore dhcp packets using ip tables filtering based<br>
on MAC address. That would work well if you configured it with a static IP.<br>
