I am having a problem while trying to download anything from a recently
configured tftp boot server.
Here are the configuration for the dhcpd.conf
option domain-name="domain.com";
default-lease-time 900;
max-lease-time 1800;
ddns-update-style none;
authoritative;
allow bootp;
allow booting;
option space PXE;
option PXE.mtftp-ip code 1 = ip-address;
option PXE.mtftp-cport code 2 = unsigned integer 16;
option PXE.mtftp-sport code 3 = unsigned integer 16;
option PXE.mtftp-tmout code 4 = unsigned integer 8;
option PXE.mtftp-delay code 5 = unsigned integer 8;
subnet 155.97.17.160
netmask 255.255.255.224 {
option domain-name-servers ns.domain.com, ns1.domain.com;
option routers routerIP;
}
group {
next-server tftp_server;
filename "pxelinux.0";
host PXE-Client {
hardware ethernet 00:02:B3:EF:75:39;
fixed-address 192.168.0.1;
}
}
Here are is the tcpdump data being recieved when getting a pxelinux.0
13:52:42.837342 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF],
length: 50) 192.168.0.2.1027 > tftp.server.com.tftp: [udp sum ok] 22
RRQ "pxelinux.0" netascii
13:52:47.834011 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF],
length: 50) 192.168.02.1027 > tftp.server.com.tftp: [udp sum ok] 22 RRQ
"pxelinux.0" netascii
And here is the output of a tftp request for the same file
tftp> get pxelinux.0
getting from 155.97.16.163:pxelinux.0 to pxelinux.0 [netascii]
sent RRQ <file=pxelinux.0, mode=netascii>
sent RRQ <file=pxelinux.0, mode=netascii>
sent RRQ <file=pxelinux.0, mode=netascii>
sent RRQ <file=pxelinux.0, mode=netascii>
sent RRQ <file=pxelinux.0, mode=netascii>
Transfer timed out.
The transfer times out and I am left with a file "pxelinux.0" with a
filesize of 0 bytes.
I am not able to find any information regarding this problem using
google or searching the syslinux mailing list. Any help is appreciated.
