PXE Boot not working properly from Storage Node

Silv4n

Hey guys

When I try to PXE Boot to an Storage Node it works, but the FOG Screen seems broken and deploying etc. doesn’t work. Screen when booted in FOG Menu

For context:

My Master Node is in a different subnet than my storage node, i’ve opened FTP, MySQL, HTTP and HTTPS between those, and replication etc. seems to work.

Thanks in advance for any help!

Edit: Also when trying to execute memdisk the following error comes up:

@Silv4n Oh well, I should have read the whole topic more closely and think about it a bit more. Copying the certs for Apache from the master server over will cause trouble because it’s got the wrong IP/DNS name in it.

In this case I’d suggest you re-run the installer on the storage node and tell it to recreate the Apache cert and key.

Make sure have set httpproto='https' in /opt/fog/.fogproject!
Run the installer like this: ./installfog.sh --recreate-keys

The pxe boot screen is kind of expected on certain uefi based computers. Its ugly but a function of the uefi firmware. You do not get a pretty colored screen, just the basic screen.

Is your storage node a FOG storage node or a converted NAS like synology?

It’s a FOG Storage Node, and when I used to boot from the master, the screen looked normal on the same pc.

@Silv4n Will you collect some information for me?

At the main site dhcp, what are the settings for options 66 and 67
At the remote site dhcp what are the settings for the options 66 and 67.

At the remote site for the FOG storage node. Post the content of the /tftpboot/default.ipxe file.

Key in the following URL once from the main fog server and once from the remote storage node.

http://<ip_address>/fog/service/ipxe/boot.php

This will give you a screen full of text. The text represents the fog boot menu. There is something going on that we don’t understand at the moment.

@Silv4n The root of the issue is the main site uses https and the remote sites are using http.

Silv4n

@george1421 Ok, I’ve actually even tried to reinstall the storage node with https, but it gave me an error. Can I use a master node instead, which still uses the db etc. on the main server or should the storage work with https?

george1421

@Silv4n This is an interesting problem. I think we will need to ping the @developers on this one. I’m pretty sure we can just copy over the apache stuff from the master node to the storage node to enable https, on the storage node. The issue is telling the storage node to use https in its scripting vs http.

Silv4n

@george1421 I’m gonna assume, that I can’t just change the boot.php file from the remote site to use https, right?

george1421

@Silv4n There is a setting some place where it defines which protocol to use. There is a text based config file in the fog www directory.

george1421

@george1421 It would be interesting if you copied over the apache certificates from the master node to the storage node as well as the apache configuration required to make the storage node https compatible. THEN in the storage node configuration there is a web url setting where we need to add in https.

This is just me thinking without any input from the developers.

Silv4n

@george1421 Hmm, okay thanks for your input, I guess I’ll wait till the devs can confirm this, before breaking the storage node or something, because the sync for example works without any issues.

Silv4n

@george1421 Nvm, I’m gonna try

george1421

@Silv4n said in PXE Boot not working properly from Storage Node:

Nvm, I’m gonna try

That was my thought, it already doesn’t work. How bad could you make it?

Silv4n

@george1421 I haven’t copied the certs over yet, because there were already certs on the server, but now this error appears in the apache log, I’m not sure if copying over solves that:

george1421

@Silv4n Your link only contains an ugly picture of the US president in the ad. Please do scare me like that this early in the morning. I’m a USA citizen I see enough of that here…

Silv4n

@george1421 Based on cookies i guess ;), for me it shows the screenshot, but im gonna copy it here instead:

[Wed Feb 19 15:43:44.859522 2020] [ssl:emerg] [pid 16345] AH02565: Certificate and private key 10.144.1.22:443:0 from /var/www/fog/management/other/ssl/srvpublic.crt and /opt/fog/snapins/ssl/.srvprivate.key do not match

george1421

@Silv4n I would save those existing keys off to the side and then copy the keys over from the main fog server. This is not ‘technically’ the right way, but we just need to see it work right now.

The right way would be to build new keys for the storage node using the root CA created on the master FOG node.

Silv4n

@george1421 Alright, I’m gonna test that tomorrow morning or tonight and than I’ll leave feedback here.

Silv4n

@george1421 Alright, I’ve copied over the

/opt/fog/snapins/ssl/.srvprivate.key

And the apache service started now and after a reinstall with HTTPS (which worked now without an issues) I can access the Web GUI of the Storage Node via HTTPS. It also generated a new boot file etc. However, the PXE Boot still throws the chainloading error, when trying to actually boot in to something. It also tries to connect there still with HTTP.
