<enaut-web>
hey all! I'm having a hard time booting some HP systems in uefi mode... after selecting pxe mode from bootmenu they just say "start PXE over ipv4 MAC: ...." then some timout occurs
09:18
<alkisg>
enaut-web: hi, run `journalctl -fu dnsmasq` on the server, and see if it sees the client request
09:18
Btw, do BIOS clients boot?
09:18
<enaut-web>
Yes Bios clients boot and the same client in compatibilitymode boots too...
09:20
Feb 06 10:19:28 LehrerServer dnsmasq-dhcp[144832]: PXE(ens18) 2c:f0:5d:ae:d1:1a proxy
09:20
is the message that appears... besides older stuf
09:21
<alkisg>
Yup, that's good enough, it hints at something broken with the uefi firmware; I've seen a few of those...
09:21
Can you test it in non-proxy mode?
09:21
I.e. set a server nic to 192.168.67.1, put the client directly there, and see if it boots
09:21
<enaut-web>
how do I disable
09:22
<alkisg>
If it does, then it doesn't like something in proxydhcp
09:22
You don't need to touch anything in dnsmasq, you only need to set a static ip
09:22
specifically, 192.168.67.1
09:22
But don't do that in the same subnet as your main dhcp server
09:22
Either use a separate nic, or temporarily use a direct cable connection from server to client
09:23
<enaut-web>
ok...
09:23
<alkisg>
If your UEFI firmware has a "check for updates" function, now it would be a good time to do it :D
09:23
As they may have solved the bug already...
09:27RaphGro has left IRC (RaphGro!~raphgro@fedora/raphgro, Quit: Please remember your own message. It'll be read as soon as possible.)
09:28enaut-web has left IRC (enaut-web!5b173cce@p5b173cce.dip0.t-ipconnect.de, Ping timeout: 240 seconds)
09:32enaut-web has joined IRC (enaut-web!5b173cce@p5b173cce.dip0.t-ipconnect.de)
09:32
<enaut-web>
Ok it did not change anything with the ...1 ip address
09:32
<alkisg>
enaut-web: did it say proxy now, or did it offer an ip?
09:32
the dnsmasq log
09:33
<enaut-web>
oh is it important to have the exact ip 192.168.67.1 because I used 192.168.20.1
09:33
<alkisg>
Yes, otherwise it doesn't work
09:34
<enaut-web>
still the same line
09:34
oh ok then Ill be back soon...
09:34
<alkisg>
ok

<enaut-web>
alkisg: I did a bios update which helped on one computer but not on the HP ones (which are the ones actually need to be netbooted)...
10:49
with the 67.1 ipadress it works fin
10:50
*fine

11:02
<alkisg_web>
enaut, in ltsp-dnsmasq.conf, try to add a root-path of /srv/tftp
11:02
Then restart dnsmasq and test again
11:04
If that doesn't work, you'll either need to use real-dhcp, or local ipxe, e.g. disk or usb stick
11:15alkisg_web has left IRC (alkisg_web!6db2a435@109-178-164-53.pat.ren.cosmote.net, Quit: Ping timeout (120 seconds))
11:19
<enaut-web>
alkisg: in dnsmasq.d/ltsp-dnsmasq.conf there is the line: dhcp-option=option:root-path,ipxe-menu-item uncommenting that one did not help should I modify this to: dhcp-option=option:root-path,srv/tftp or similar?
11:20
by real dhcp you mean I need access to the actual dhcp server in the network and configure that one accordingly?
11:21
or split out the netboot network with: https://ltsp.org/advanced/isc-dhcp-server/?
11:31alkisg_web has joined IRC (alkisg_web!6db2a435@109-178-164-53.pat.ren.cosmote.net)
11:31
<alkisg_web>
enaut, yeah no need to test more with root path
11:32
You'll either need to modify the real dhcp, or use local ipxe
11:33
Or to use split real dhcp which again requires access to the real dhcp

<enaut-web>
thanks - maybe it is easier to just enable legacy mode... and I will probably bother the HP-Support :)
11:41
Thank you so much
