Re: dhcp server (udp packet size)
I still can't get some clients to receive my dhcp packets. After some more testing i figured out packet size differences. In other dhcp server responses it's 342 bytes ... on radius dhcp server i've 618 bytes. Is it possible to make send back messages as short as possbile ? :) Also found some references that dhcp clients can refuse messages if thay are larger that expected. Haralds from rfc: The client SHOULD include the 'maximum DHCP message size' option to let the server know how large the server may make its DHCP messages. The parameters returned to a client may still exceed the space allocated to options in a DHCP message. In this case, two additional options flags (which must appear in the 'options' field of the message) indicate that the 'file' and 'sname' fields are to be used for options. - List info/subscribe/unsubscribe?

Re: dhcp server (udp packet size)
I've net with over 1k dhcp clients. Problem with packet size was with linksys routers. They have udhcp client. Now it looks ok. Will do more testing.

Re: dhcp server (udp packet size)
Hi, I've net with over 1k dhcp clients. so? you just sniff the traffic of one of them...or a limited subnet of those. or, you sniff the traffic on a single client itself. alan - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
Re: dhcp server (udp packet size)
All of them .. i've redundant(duplicate) dhcp server also :) I tried to comapre response packets from both servers, new one (freeradius dhcp) and old one. And understand what's different. - Original Message - From: [EMAIL PROTECTED] To: FreeRadius users mailing list freeradius-users@lists.freeradius.org Sent: Friday, June 20, 2008 11:54 PM Subject: Re: dhcp server (udp packet size) Hi, I've net with over 1k dhcp clients. so? you just sniff the traffic of one of them...or a limited subnet of those. or, you sniff the traffic on a single client itself. alan - List info/subscribe/unsubscribe?
