PXE-E32 Error; Not sure what went wrong.
-
@jazkw said in PXE-E32 Error; Not sure what went wrong.:
TFTP server address
Just to confirm, the dhcp option 66 setting needs to be the fog server IP address.
Also are you getting an error message? If so is it a PXE-XXXX message or something about NBF file size?
-
@JazKW The PXE-E32 error code means a TFTP timeout. So I suspect you have option 66 not pointing to the correct server. Is it set to the FOG server IP address? Is your TFTP server running and working properly. Please follow this to make sure: https://wiki.fogproject.org/wiki/index.php/Troubleshoot_TFTP
-
@sebastian-roth The ip address in option 66 and that of the fog server match.
-
@JazKW Please follow the TFTP troubleshooting guide and let us know what you get.
-
@sebastian-roth TFTP was not enabled in firewalld so it was not getting through, but I’ve run into another error.
Could not boot: Connection timed out (http://ipxe.org/4c0a6035)
I did check the specified files on the wiki and the IP address is correct for both files. But in .fogsettings submask has: ‘Error: =4099<UP,BROADCAST,MULTICAST> is not recognized’ instead of an actual subnet mask, would this be the possible cause? -
@JazKW As far as I know from the top of my head the submask setting is mostly used to generate a valid DHCP config. If you are using a Windows DHCP server, that should not cause an issue. But I am wondering if DHCP on your FOG server is still running and might cause an issue? Please run the following commands and post results here:
ps ax | grep dhc cat /opt/fog/.fogsettings -
@sebastian-roth This is the result I got from the two commands:

@JazKW As far as I can see there is no DHCP server running or configured in fogsettings. Can you please take a picture of the
Could not boot: ...error on screen. Possibly there is some important information we are still missing. -
@jazkw The question I wonder is why dnsmasq is running on this computer? There are valid uses for dnsmasq with FOG, but why its active with this setup.
-
@george1421 It shouldn’t be. I have it set up with the windows DHCP server. If dnsmasq is running, it shouldn’t. So at this point I would be asking how to turn it off, because it seems like it’d be what’s causing the Host machine not to be able to PXE boot.
-
-
@jazkw Well it depends on what mode dnsmasq is configured in. If its setup as proxydhcp then it could be mucking up the works. The config file path shown is not something that FOG would setup or configure. That looks like some other application configured dnsmasq for you.
If in doubt, key in
systemctl stop dnsmasqto temporarily stop the service. Then try to pxe boot. If you still can’t understand what is going wrong then lets capture a packet trace of the pxe booting process. As long as the FOG server and the pxe booting client are on the same subnet, we can use FOG to spy on the pxe booting process. If the target computer is on a different subnet then we will need a second computer on the pxe booting computer’s subnet with wireshark installed.I have a tutorial on how to capture a pcap of the pxe booting process here: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue
-
@george1421 Stopping dnsmasq didn’t change anything, still the same result and same error. Need to review network policy before attempting a packet capture.
-
@jazkw OK fair enough. Just be aware with the capture filter defined in that article only pxe booting and dhcp process will be captured in the pcap. No PII is available at this point in the booting process. Even windows isn’t involved where we want to capture. Now I agree if you don’t use the exact capture filter I defined you may indirectly capture info you don’t want.
If you are able to capture a pcap, but don’t want to post it here, or IM me the link to the pcap, we can still work indirectly via your eyes with the pcap, but it will take much longer that way.
-
@george1421 There is one other thing I’ve noticed each time I went to uninstall and reinstall FOG, none of the services exist.
When I go to run these commandssudo rm /etc/init.d/FOGImageReplicator sudo rm /etc/init.d/FOGMulticastManager sudo rm /etc/init.d/FOGScheduler```I get:
[root@FOG NetworkManager]# sudo rm /etc/init.d/FOGImageReplicator
rm: cannot remove ‘/etc/init.d/FOGImageReplicator’: No such file or directoryFor each one; and when I go to check where they’re supposed to be located, they aren’t there
[root@FOG init.d]# ls -la total 40 drwxr-xr-x. 2 root root 70 Aug 6 10:33 . drwxr-xr-x. 10 root root 127 Aug 6 10:32 .. -rw-r--r--. 1 root root 18104 Jan 2 2018 functions -rwxr-xr-x. 1 root root 4334 Jan 2 2018 netconsole -rwxr-xr-x. 1 root root 7293 Jan 2 2018 network -rw-r--r--. 1 root root 1160 Apr 11 03:36 README -
@jazkw I’d have to look into what the installer is doing, but your FOG server is running in a systemd environment not systemv as the older versions of linux. SystemD uses systemctl which stores the init files in a different location instead of init.d (that is where systemv uses).
-
@george1421 Not sure if you have any control over it, but you may want to update the uninstall article on the wiki for systemd. I may have bad or redundant service files from previous install attempts, unless they were overwritten.
-
@JazKW Thanks for the picture. I see
http://.../boot.php...................... Connection timed out .... This is a big issue. The client is not able to load the iPXE menu stuff and fails. Are you able to open this URL in your browser from a PC within your network: http://192.168.1.87/fog/service/ipxe/boot.phpMy guess is that you have a local firewall not allowing this connection. Please check using
sudo iptables -L -n -v(post full output here). -
@sebastian-roth No I was not able to connect to the Fog server from another PC.
EDIT: Disabling firewalld got it to work.

EDIT: Disabling firewalld got it to work.
Just add TCP port 80 to your firewall config and you should be fine. Although there might be later issues with NFS… If you are not familiar with firewall configuration you might want to leave it disabled for now till you have it all up and running. Later on you can still enable it again and add ports as needed.
