    Ok, did that. 

    Using tftp-ha: 
    [root at englab1 root]# /usr/sbin/in.tftpd -V
    tftp-hpa 0.32, with remap, with tcpwrappers

    I can successfull pull pxelinux.0 to my desktop (off the eth3
    interface), but I cannot seem to get it off the server: 

    Here is the syslog going to my desk: 
Oct 30 00:05:37 englab1 in.tftpd[3370]: RRQ from 10.128.1.234 filename /pxelinux.0 
Oct 30 00:05:38 englab1 in.tftpd[3370]: tftpd: read(ack): Connection refused

    pxelinux.0 successfully is copied over (md5sums match). 

    Here is the console from a pxeboot: 

DHCP MAC ADDR: 00 D0 B7 88 01 52

PXE-M0F: Exiting LANDesk (R) Service Agent II                                   

    And the syslogs: 

Oct 29 16:28:54 englab1 dhcpd: DHCPDISCOVER from 00:d0:b7:88:01:52 via eth0
Oct 29 16:28:54 englab1 dhcpd: DHCPOFFER on 10.150.0.51 to 00:d0:b7:88:01:52 via eth0

Oct 30 00:29:38 englab1 in.tftpd[3383]: RRQ from 10.150.0.51 filename /pxelinux.0 

    And the logs from an attempt:
Oct 30 00:33:18 englab1 in.tftpd[3384]: RRQ from 10.150.0.51 filename /pxelinux.0 
Oct 30 00:33:18 englab1 in.tftpd[3384]: tftpd: read(ack): Connection refused

Oct 30 00:33:28 englab1 in.tftpd[3386]: RRQ from 10.150.0.51 filename /pxelinux.0 
Oct 30 00:33:28 englab1 in.tftpd[3386]: tftpd: read(ack): Connection refused
Oct 30 00:33:33 englab1 in.tftpd[3387]: RRQ from 10.150.0.51 filename /pxelinux.0

Oct 30 00:33:38 englab1 in.tftpd[3388]: RRQ from 10.150.0.51 filename /pxelinux.0 
Oct 30 00:33:38 englab1 in.tftpd[3388]: tftpd: read(ack): Connection refused

    In this latter case the pxelinux.0 file is not copied over. 

    tftpd is being started as in.tftpd from xinetd with these args: 
    server_args             = -cvvp -a 10.150.0.1:69 -s /tftpboot

    Which really should mean that my desktop can't get to the machine at
all, since it's coming in on the 10.128.x.x interface. 

    It's entirely possible I've got the server severely misconfigured
here--We're in the process of evaluating whether to switch from Debian
to Redhat, and I've not yet found were the folks at Redhat stick all of
their configuration stuff.
