PXE-32: TFTP open timeout

[Geonon]

I'm running OPSI on Ubuntu 12.04, I ran through the getting started guide available from the opsi website. Everything appears to be working correctly expect the tftp agent. When attempting a network boot I get the error "PXE-32: TFTP open timeout". I've searched through the forums here, and through Google. I haven't been able to find anything to resolve this issue. The atftpd service appears to be running, all directories are available (tftpboot) and have the correct permissions.

I'm sure I'm missing something simple, I've looked at the opsi config over and over I am not finding it. If anyone out there would like to help me find out where I went wrong in this configuration I would greatly appreciate it.

Hi,

there are two possibilities:
1. your client do not ask the opsi server (because the dhcp answer isn't correct)
2. There is any problem on your server.

To check this:
a) look for atftpd entries in your /var/log/syslog
b) try:
tcpdump port tftp

If this command do not show any traffic from your client - your client do not ask your server (or there is a firewall between)

The log file at var/log/syslog appears to be empty.

The results from the tcp dump are the following

I partially understand the output, I'm not sure what I should be looking for after "lts-linux.lts.office.tftp:" on each line.

One line that did stand out to me was towards the top, it list "link-type EN10MB". Is this a problem?

I ran "dmesg | grep -i duplex" and it shows that I'm at 100Mbps full duplex.

I cancelled the TCP dump because at that point the client computer had moved on the next boot device.

Hi,

ok - dhcp seems to fine and the problem is at the server:

Is the opsi-atftpd installed ?

Code: Alles auswählen

dpkg -l | grep opsi

Is the openbsd-inetd installed ?

Code: Alles auswählen

dpkg -l | grep inetd

Is the tftpd configured in the /etc/inetd.conf ?
Does the inted running ?

regards

All the necessary programs appear to be installed. The tftpd configuration file appears to be set to default. Everything is commented out. Do I simply need to uncomment the boot server option? Looking at the file it doesn't seem that simple.

Using the "service inetd status" command, it shows the service is unrecognized. I'm guessing that's where my problem is. Is this simply because of the unconfigured tftpd file?

[d.oertel]

Hi,

try a

Code: Alles auswählen

dpkg-reconfigure opsi-atftp

and then check if your ined.conf has a valid configuration.....

When attempting to run "dpkg-reconfigure opsi-atftp" I was given an error message saying that the service wasn't installed. I had to clear out the old files in /boot in order to get it installed. Maybe I missed this error when running through the guide. Once installed I didn't see any changes to inetd.conf, so I ran the reconfigure command. It ran but I still didn't see any changes to the file.

I ran "dpkg -l | grep opsi" to look at the packages again, and I noticed I have opsi-atftp and opsi-atftpd installed. I ran reconfigure on the atftpd package, and was given a short setup wizard to go through. After which I am no longer getting the tftp timeouts.

The only issue I've noticed now is that everything is in German when booting to the opsi server. Is there an easy way to change this to English? And do I need both the atftp and atftpd packages?

Hi,

that everything is in German when booting to the opsi server

Could you give some more details please.
Normally for everything English is the fallback language.

Hi,

And do I need both the atftp and atftpd packages?

No, you need only the opsi-atftpd package. The opsi-atftp package is generated by the same source-package, that's why it's available on our Repositories. You need the opsi-atftp (client), when you want to test your PXE-Server, or when you need to communicate with an external TFTP-Server.

everything is in German when booting to the opsi server

please execute the following command and post the result:

Code: Alles auswählen

locale

@d.oertel

When PXE booting, if you choose to load the opsi client instead of booting to the local hdd. Any opsi menu that then appears is in German. So when selecting the run a hardware inventory, or to image a machine, all the menus are in German. It even appears as if it's a German Windows install that it wishes to launch, when you select one of the Operating System options. The webGUI is in English, I haven't noticed the language being anything but English except when PXE booting. I have downloaded the client CD, and used that to boot to the opsi server. When using the CD to boot, all the opsi menus are in English, but when I select one of the Operating System options it list German (Deutsch). It doesn't list this on the main selection screen, just after the selection of the Operating System has been made. (At least as I recall, I will verify all this once I'm in the shop today.)

I hope I explained that correctly. Just to reiterate when using the CD to boot, all the menus and options are in English. It's just that after selecting an Operating System, on the next screen that pops up, it list the OS I selected. The word Deutsch is listed after the OS name. I assume this means it is going to install Windows with German being the installation language and locality setting.


@ueluekmen

In that case I will remove the opsi-atftp package, it doesn't appear that I will be needing it at this time.
