ltsp setup

I'm getting ready to run LTSP at work and I've got a lot of it configured. According to the administration application, tftpd is not installed on my system and neither is dhcpd. Sddly, I have no idea where to get these. Do I need tftpd-0.17-20.i386.rpm for tfptd and hcpd-2.0b1pl0-1.i386.rpm for dhcpd? I can't seem to locate any good documentation for either and the ltsp documentation just assumes I have them on the system (odd that they didn't include anyhting because the documentation is really well done).

Anyone?
