Using bootp server versus a boot helper server

SDS FDX — Wed, 28 Dec 2005 10:51:03 GMT

I have a three fold question for anyone who can offer any help?

On a network with many different switches and subnets, is it a good idea to use an ignite server also as a bootp server? I am thinking about configuring the switches on each subnet, to route all bootp request to my ignite server.

If I route all bootp requests to my bootp/ignite server, will that cover the PXE and DHCP boot requests as well, which is used by intel-based servers such as linux? OR Are DHCP and bootp requests one in the same?

When configuring the ignite server as a bootp server, will I be able to only use the /etc/bootptab to satisfy PXE boot requests (intel-based), DHCP requests, and bootp requests (PA-Risc)? OR do I have to use the /etc/dhcptab file?

Dear Michael,

I feel you have to configure BOTH in the server, since PA servers use bootpd ( UDP 1067 & 1068 ), wheras IA uses DHCP. having bootptab alone wont serve the DHCP requests.

With Regards,

Siva.

Thanks Siva! So I'm guessing the DHCP requests and the bootp requests AREN'T one in the same. They are two seperate requests?

I was just reading the Ignite Administration Guide, and it suggested that the /etc/bootptab file can be used as a alternative to DHCP. It reads "Because the Bootstrap Protocol (BOOTP) is a subset of the DHCP protocol, the clients's request for a DHCP server will be satisfied with the BOOTP response." I'm assuming the only difference between the two will be that the /etc/dhcptab file will be used for anonymous boot clients, and the /etc/bootptab file will be used for know clients. Is this correct?
