TFTP Troubleshooting
 
Tom,

I did check that :-). My configuration looks like this:

# default: off
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
per_source = 11
cps = 100 2
flags = IPv4
}

Thanks,
- Ole

Stick "-vvv" after "-s /tftpboot" and check /var/log/messages and
compare them with the messages you are seeing on the client.
If it helps to convey what you are seeing, take a picture of the booting
client with a camera. Share the text of both.


Generally debugging TFTP, firewalls, and network setup is off-topic for
this list as it doesn't pertain directly to Cobbler or the virt tools, a
good place for this if you can join is #cobbler on irc.freenode.net.

TFTP Troubleshooting
 
Michael,

I put -vvv in like this:

server_args = -s /tftpboot -vvv

Then restarted xinetd + ran cobbler sync (Just in case).

/var/log/messages looks like this (From this last attempt):

Jun 3 13:07:55 localhost dhcpd: DHCPDISCOVER from 00:16:ec:cc:d1:f6 via eth0
Jun 3 13:07:55 localhost dhcpd: DHCPOFFER on 192.168.1.2 to 00:16:ec:cc:d1:f6 via eth0
Jun 3 13:07:57 localhost dhcpd: DHCPREQUEST for 192.168.1.2 (192.168.1.6) from 00:16:ec:cc:d1:f6 via eth0
Jun 3 13:07:57 localhost dhcpd: DHCPACK on 192.168.1.2 to 00:16:ec:cc:d1:f6 via eth0

I attached a picture of my monitor.

Oh Maan - I have to get out of my email zone? OK - I'll check it out :-).

We narrowed this down on IRC, and the "next-server" setting (which is in
/etc/dhcpd.conf) was not set to the Cobbler server, but to another box

that wasn't running TFTP, hence the open timeout.

So, good deal :)
