I'm trying to set up a kickstart server on my home network. I can't get
network booting working. DHCPD and tftp are working, but the tftp request
on the client is timing out with:
PXE-E32 TFTP open timeout
I've googled the heck out of this issue and can't find a fix. I was hoping
someone here could help me out.
My dhcpd.conf file:
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.example
# see dhcpd.conf(5) man page
#
option space pxelinux;
option pxelinux.magic code 208 = string;
option pxelinux.configfile code 209 = text;
option pxelinux.pathprefix code 210 = text;
option pxelinux.reboottime code 211 = unsigned integer 32;
allow booting;
allow bootp;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) =
"PXEClient";
next-server 192.168.10.90;
filename "pxelinux.0";
}
subnet 192.168.10.0 netmask 255.255.255.0 {
option domain-name "larsenhaus.org";
option domain-search "larsenhaus.org";
option domain-name-servers 192.168.10.60,192.168.10.90;
option routers 192.168.10.10;
range dynamic-bootp 192.168.10.100 192.168.10.200;
default-lease-time 3600;
max-lease-time 4800;
}
My xinetd tftp file:
# default: off
# description: The tftp server serves files using the trivial file transfer
\
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware

The netbook acquires an IP address from DHCP and begins the tftp request,
but times out as described above. tcpdump shows the client connecting to
the tftp server:

But no boot.
During my research I saw a post somewhere that talked about tftp having
issues with some RealTek network cards. The kickstart server is running a
controller with the RTL8101E/RTL8102E chipset. The poster said he fixed his
problem by setting the tftp block size explicitly to 512, but I've been
unable to determine how to do so.
Are there any obvious errors in my configuration? If not, can anyone advise
how to set the tftp block size? Thanks in advance.
