TFTP stops on reboot after install
-
For us in Ubuntu 12.04 the problem was tftpd-hpa was not starting because fog installation modified the file /etc/default/tftpd-hpa with an IP address of 0.0.0.0
-
I just stopped and started tfpd-hpa:
[code]
sudo stop tftpd-hpa
sudo start tftpd-hpa
[/code] -
More details:
This is a common issue that keeps coming up in the forums. You install 12.04, install fog and reboot and then TFTP times out.Look in your /var/log/syslog file and you’ll see something like:
[Code]
May 22 14:16:22 yourServer in.tftpd[968]: cannot resolve local IPv4 bind address: 0.0
.0.0, Name or service not known
May 22 14:16:22 yourServer cron[1003]: (CRON) STARTUP (fork ok)
May 22 14:16:22 yourServer kernel: [ 19.271357] init: tftpd-hpa main process (968)
terminated with status 66
May 22 14:16:22 yourServer kernel: [ 19.271374] init: tftpd-hpa main process ended,
respawning
[/code]
Your nic doesn’t have an IP address when tftpd-hpa starts, so it isn’t going to work. Just do this from a terminal window:
[Code]
sudo stop tftpd-hpa
sudo start tftpd-hpa
[/code]
This is a “confirmed” bug in 12.04.–astrouga

I think the reason is the Ubuntu start mechanism “Upstart”, where the daemons do not start step by step but almost simultaneously.
So tftpd-hpa starts “to early”. You can fix this by editing the /etc/rc.local and ad the line(/bin/sleep 30 && /etc/init.d/htftpd-hpa restart)
to restart the daemon after 30 seconds

Thanks, that worked. Though you have a typo. It should be:
[CODE]/bin/sleep 30 && /etc/init.d/tftpd-hpa restart[/CODE]
(you had “htftpd-hpa”).

[quote=“astrouga, post: 3627, member: 907”]I just stopped and started tfpd-hpa:

I did the same, …actually aliased the command to “restart tftpd-hpd” -
Just curious since I have encountered this ‘bug’ with the Ubuntu releases all the time:
Instead of restarting with:
[FONT=Consolas][CODE]/bin/sleep 30 && /etc/init.d/tftpd-hpa restart[/CODE][/FONT]
[FONT=Consolas]Isn’t there a way to delay the original start of the tftp daemon with a simple sleep () inserted somewhere in the Ubuntu start up script for all daemons?[/FONT]

Still can’t figure out why all of the sudden I’m getting the notorious PXE-E53 and PXE-M0F errors. Anyone with a solution? I’m behind my home router that does the DHCP, has been working great. My mistake was rebooting my fog server, now I got nothing > ugg!

Circling back here folks.
SOLVED!
From spiceworks post:
This is kind of an old thread at this point, but I had the same issues so I wanted to put the information I found on here in the event it will help anybody else…what I found was that both DHCP, and TFTP had stopped working when I rebooted my 12.04 ubuntu LTS desktop. After doing some testing, here’s what I found that works for me to get it restarted quickly.
FROM THE UBUNTU Desktop- Open a command window
- ENTER: sudo start isc-dhcp-server (enter your password when asked)
- ENTER: sudo restart tftpd-hpa
BAM!

This is a known issue with the 12.04 Ubuntu derivative, the services are started before an ip address is assigned to the machine.
There are a number of posts ON THIS FORUM that explain how to rectify the issue and delay the start up of the job so that you don’t have to start them manually after each reboot.
