Steve, Thank you very much for getting back to me. This issue has become very frustrating and a truly appreciate your help. I wanted to make sure that the Windows 2003 SBS acting as the DHCP wasn't part of the problem so I removed it from the equation. I am now running the DHCP service on the LTSP server and only serve static addresses to the subnet that I am trying to remote boot from (192.168.50.X). This is working fine. The remote client gets the IP address 192.168.50.35 and then requests the file /ltsp/i386/pxelinux.0 from the TFTP server. The following is shown in the syslog when this happens.
Jun 8 00:17:20 debian in.tftpd[5411]: RRQ from 192.168.50.35 filename /ltsp/i386/pxelinux.0 The remote client just hangs here and nothing is ever transferred. I checked the hosts.allow and hosts.deny and nothing was in there. I added the following to hosts.allow: ALL: 192.168.50.0/255.255.255.0 But this doesn't seem to help. Also, there is nothing in the iptables either. I am completely stumped now. Is there a way that I can see why tftpd-hpa is not able to send the file? Could this be a netmask issue within dhcpd3.conf? Does the default install of Debian have a firewall that I don't know of? Any more help you can give me would be great. Regards, Aaron J. Wood Regards, Aaron J.

It's more likely that packets are being blocked by a firewall or by tcpwrappers. I would look in the logs for dropped packet notices or any information from tftp -- you can boost the logging verbosity with "-v" in /etc/default/tftp-hpa (on my Ubuntu machine anyway). Look at the manual page for tftpd ("man tftpd") for more options; it's a very simple daemon. Try "iptables -L -n -v" to see if you're dropping packets to port 69 from anywhere (tftp uses the UDP protocol). Look in /etc/hosts.allow and /etc/hosts.deny to see if you have any tcpwrapper rules affecting your tftp daemon. Hope one of these ideas helps. -Steve Aaron J.
