dhcp issue...

[Andreas Sindermann]

Dear all,

currently I'm trying to set up a fai installation server (Debian 11.3
bullseye) that in the end is supposed to install XUbuntu 22.04 (jammy)
desktop clients.


It seems that the dhcp service currently doesn't seem to recognize the
dhcp request from the test client, see screenshot attached.


Nevertheless the dhcp service seems to be configured and listening
correctly:


root at jammysrv:~# ps -ef|grep dhcp
root        1578       1  0 May30 ?        00:00:00 /usr/sbin/dhcpd -4
-q -cf /etc/dhcp/dhcpd.conf ens160
root at jammysrv:~# lsof -i -P -n |grep -i dhc
dhcpd     1578   root   10u  IPv4  22844      0t0  UDP *:67
root at jammysrv:~# cat /etc/resolv.conf
# Generated by NetworkManager
search thp.uni-koeln.de
nameserver 134.95.127.1



root at jammysrv:~#  cat /etc/dhcp/dhcpd.conf
# dhcpd.conf for fai
# replace faiserver with the name of your install server

#do not assign ip to unknown mac addresses
deny unknown-clients;

#automatically assign host name (as specified below) to clients
use-host-decl-names on;

#filename "fai/pxelinux.0";
#discriminate conventional BIOS setup and UEFI setup
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:00000" {
         filename "fai/pxelinux.0";
}
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:00007" {
         filename "fai/syslinux.efi";
}
#filename "fai/syslinux.efi";

subnet 134.95.67.0 netmask 255.255.255.0 {
   option routers 134.95.67.254;
   option domain-name "thp.uni-koeln.de";
   option domain-name-servers 134.95.127.1;
   option time-servers 134.95.67.254;
   option ntp-servers 134.95.67.254;
   server-name "134.95.67.208";
   next-server 134.95.67.208;
}


host l100 {hardware ethernet B4:2E:99:87:23:8B;fixed-address l100;}



Currently I have no idea where to look for to resolve this issue, hmm...


Any advice is very welcome...


Andreas
