Tftp stops working a few minutes after starting

[elijahkan14]

I’m having a rather strange problem. I had a FOG server running 0.32 on Ubuntu 11.10, recently it was upgraded to 1.1.1 and it’s been going alright except for this problem:
The server boots and everything works fine for a few minutes. After a while, when clients boot to the network they are able to get a DHCP address (from a windows server) and then gets an open timeout error on TFTP and sits there going “Tftp…” until it times out.

I was able to temporarily fix this problem by running “sudo restart tftpd-hpa” and this works for a while but soon stops again, restarting also fixes it temporarily. I also noticed that when I SSH into the server while the problem is occurring it says “-bash: fork: retry: No child processes” [url]http://gyazo.com/4e474fb7d51cfe2c18fd21670c3e9b52[/url]

To test the server I’ve been using the tftp client of windows:

Any ideas?

Well Congratz lol!

We got the new server up and running! Out of curiosity I did “do-release-upgrade” on the old server and it offered to overwrite tftpd-hpa during the upgrade, now we have two working FOG servers! Thanks again to everyone!

Alright, thanks for all the help from everyone! I’ll start a new thread if I run into issues with this install.

That will work yes. Ubuntu is derived from Debain. They use the same base so the commands are similar.

There is really no “best” OS. I prefer CentOS, but again that’s a matter of preference rather than “the best”. You could try Debian 7.5 for familiarities sake as you’re probably more familiar with Ubuntu style commands.

Debian

Make a copy of your /images folder. And export your current database from fog to a flash drive. This will allow us to keep your database and image files to alleviate the stress of setting up a new server

I second this notion -.-

I don’t think I am, I ran [code]sudo apt-get remove --auto-remove ltsp-server-standalone[/code]
and got
