The key is WHEN do you see the traffic. The NIC gets an IP address for PXEBoot, gets it's info needed via tftp, then the NIC is RESTARTED, the driver loaded, the request sent again. It's this second request where we have the timeout issue.

I see traffic between my dhcpd/Kickstart server and client by displaying the output from tcpdump. I can't seem to get around this issue. It appears it is some sort of timeout either with dhcp or tftp or possibly both. Like I stated earlier, I have this new subnet that I am attempting to Kickstart with no luck. Thanks anyway. -----Original Message----- From: kickstart-list-bounces@xxxxxxxxxx [mailto:kickstart-list-bounces@xxxxxxxxxx]On Behalf Of Shabazian, Chip Sent: Tuesday, March 07, 2006 1:22 PM To: kevin@xxxxxxxxxxxxxx; Discussion list about Kickstart Subject: RE: TFTP Open Timeout We have seen this issue on some switches due to the time it takes for the NIC to negotiate. What version are you using, and is portfast turned on at the switch? You can force the speed and duplex by appending the following to the kernel boot parameters: ksdevice=eth0 eth0_ethtool="autoneg=off speed=100 duplex=full" Adjust as appropriate. -----Original Message----- From: kickstart-list-bounces@xxxxxxxxxx [mailto:kickstart-list-bounces@xxxxxxxxxx] On Behalf Of Kevin Landreth Sent: Tuesday, March 07, 2006 9:10 AM To: Discussion list about Kickstart Subject: Re: TFTP Open Timeout TFTP uses UDP, so my first assumption would be a firewall, due to the timeout error. However, I just noticed when you do a getent services tftp it reports 69/tcp, which is wrong, its 69/udp - Kevin L. Elizabeth.Brosch@xxxxxxxxxxx wrote: > I am having problems with TFTP.
