I've just set up a diskless server and I'm having trouble getting the clients to pull their configuration. They are able to pull an IP address and contact the TFTP server but then error out saying they cannon find the config. Anyone have any thoughts?

Sometime it can happens, that the tftp server hang, and so the whole boot process off the diskless systems hang.
Please restart the tftp server daemon.

I reinstalled the os and diskless server on another computer and still encountered the same issue. I'm still a newbie with linux, what command can I run to restart the tftp server?

Ho'k, I restarted tftpd-hpa and the clients are still unable to locate the configuration file. I installed wireshark and can see the TFTP requests and replies between my server and the client. My server is 10.10.5.20 and the diskless client 10.10.5.22. The following below is the capture from wireshark;

Yes, I was. When creating the new diskless clients, I wasn't specific with the architecture (i386). I wrongly assumed that just hitting enter would select i386 be default. Once I created the clients and specified the architecture, everything worked.
