Problem with TFTP

[Markus13]

Hi,
I’m runnig fog 0.32 on a debian 6.0.6.

Fog already worked, but these days I get when booting a client (eg. 192.168.1.5) the message

CLIENT IP: 192.168.1.5 MASK 255.255.255.0 DHCP 192.168.1.1
GATEWAY IP: 192.168.1.8
TFTP …
and nothing happens.

root@homeserver:~# netstat -an |grep :69
udp 0 0 0.0.0.0:69 0.0.0.0:*

I don’t know, what I have done.

When I do a
tfp 127.0.0.1 -c get pxelinux.0 on the server it works. When I do the same command with 192.168.1.1 (the IP of the server) nothing happens (timeout).

I have done /etc/init.d/tfpd-hpa restart. The problem stays the same.

When I restart the server it will work (!!!), but after a couple of days I get the TFTP timeout.

What can this be?

Bye,
Markus
