I just tried to get an updated kernel image. I can see it downloads successfully but then I get

Type: 1024, File: /srv/http/fog/lib/fog/fogftp.class.php, Line: 219, Message: FTP connection failed, Host: 192.168.21.82, Username: fogproject

I notice there is no FTP server running, I note that vstfpd is disabled

Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; disabled; preset: disabled)
Active: inactive (dead)

I tried starting it ( systemctl start vsftpd ) and I tried to connect using the credentials obtained from the TFTP page in the gui, however I get

500 OOPS: vsftpd: both local and anonymous access disabled!

I don’t know if is it right that I enable this service or if Fog should take care of it.

So it looks like I am stuck without FTP and cannot update kernel image.

I am on Arch Linux and installed dev-branch a couple of days ago.

I am a new user. I have installed Fog successfully in an Arch Linux VM (I had to use dev-branch (currently commit 42b459a7) for it to work (due to an issue with PHP8, I think).

Now I have tried to configure an additional boot option on my existing DHCP / TFTP server (running dnsmasq). I have added this option

pxe-service=x86PC,Fog,ipxe.kpxe,192.168.21.82

where that is the IP of the Fog server.

I had to manually start the TFTP server on the Fog server but, otherwise, it appears to work

systemctl start tftpd

I note this is configured ( /etc/conf.d/tftpd with a TFTP root at /srv/tftp rather than /tftpboot as documented ). The files are present and I can pull them using curl. So I believe that the TFTP server on Fog is good.

Now when I PXE boot a machine on my network, I get the new Fog menu option in addition to all of the others previously there. Selecting that causes it to boot from the Fog server, however after iPXE loads it then tries to chain load tftp://192.168.21.2/default/ipxe which is the address of my DHCP/TFTP server and not the Fog server. The file does not exist on my server.

BOOT SERVER IP: 192.168.21.82
PXE->EB: !PXE at 9DA9:0070, entry point ad 9DA9:0104

Configuring (net0 08:00:27:d5:66:5f)... ok
Received DHCP answer on interface net0
tftp://192.168.21.2/default.ipxe... No such file or directory (https://ipxe.org/2d12603b)

I can copy over default.ipxe and then it works, however I would have expected it to load that from itself, no?

If it has to go on my server, I don’t really want that file in the root but I can’t see if it’s possible to specify a path.

But I don’t think I should need any of these files on my TFTP/DHCP server because it just points at the TFTP hosted by the Fog server.

I should just need a menu entry directing client to the Fog IP, lile I have done with

pxe-service=x86PC,Fog,ipxe.kpxe,192.168.21.82

I’ve looked in Wireshark at what happens. I can see the message that passes the boot file name “ipxe.kpxe” and the next server IP address being 192.168.21.82.

I can see the separate Server host name field is not given (I tried adding dhcp-option=66,"192.168.21.82" to the dnsmasq config but it made no difference to this). I don’t know if that’s relevant.

I also looked in Fog TFTP Server settings page but could not see a setting that would help resolve this.

Is it possible to Dnsmasq PXE menu option and/or Fog to boot Fog iPXE and have it perform its chain-load from itself ?
