I'm trying to use PXE to boot & install RedHat boxes. I have it working with one NIC card, but am having problems with a Dell Precision Workstation 530. According to the specs the card is as follows: integrated 3C920-based 10/100 3Com? Ethernet controller with Remote Wake Up capabilities (3C905C-TX compatible) The problem with this particular machine/NIC is that it's getting ARP Timeouts when it starts the TFTP. tcpdump shows an arp request looking for the gateway, but no reply. Some background info: Server: ISC dhcp 3.0pl1 tftp-server 0.28 (ships with RH 7.3) The client machine I'm trying to boot is on a different subnet. The cisco router is relaying dhcp to the above machine. I can successfully boot different hardware with the same configuration on this same subnet. Anyone experience this or have any ideas? Thanks. -- Amy Tanner AHPCRC 612-337-3423 atanner at ahpcrc.org

Thanks.I should add that when the dhcp server & tftp server are on the *same* subnet, everything works fine. However, that's not what we'd prefer to do. Thanks again. -- Amy Tanner AHPCRC 612-337-3423 atanner at ahpcrc.org
Hi, I think the problem you have, is just normal. As far as I know of is, that DHCP-Requests which are send out on 255.255.255.255 are not routed on any router. Please take a look, if you have a possibility to tell the Router that he has to route DHCP and Bootp-Requests, on some router you can adjust this inside the Configurations. It's just the same problem with NetBios that isn't routed also. The other way would be, install a Linux BOX inside your subnet where the Boot-PC is connected and install a DHCP-RELAY on SuSE x.x you will find such a utility. What the RELAY should do is take the request and forward it the way your router will understand and route those packages. If you can't find this package for your Linux Distribution take a look at: http://www.isc.org/products/DHCP/ There you should find the Software you need, except you need to compile this stuff, and it's a good way to update your DHCP-Server also !!!
