Re: [xcat-user] From where next-server is fetched from?
LOL. I feel like an idiot right now.
Hmmm thanks Kilian, you're indeed correct. I need to understand now why it
wasn't working and started working when I manually override the next-server
variable.

Re: [xcat-user] From where next-server is fetched from?
I don't think it needs to be expanded by xCAT in the DHCP lease file.
dhcpd will literally send the
"http://${next-server}:80/tftpboot/xcat/xnba/nodes/adano43; string in
the DHCP reply, and the TFTP/PXE client will interpret this using the
"next-server" value that is defined at the subnet level in dhcpd.conf.
Some examples here: https://wiki.alpinelinux.org/wiki/PXE_boot#HOWTO

[xcat-user] From where next-server is fetched from?
Hello, I'm running xCAT development build and makedhcp is falling to proper
populate next-server on /var/lib/dhcpd/dhcpd.leases:
As an example:
host adano43 {
dynamic;
hardware ethernet 00:11:22:33:44:55;
uid 00:11:22:33:44:55;
fixed-address 172.26.0.43;
supersede server.ddns-hostname = "adano43";
supersede host-name = "adano43";
if option user-class-identifier = "xNBA" and option client-architecture
= 00:00 {
supersede server.always-broadcast = 01;
supersede server.filename =
"http://${next-server}:80/tftpboot/xcat/xnba/nodes/adano43;;
} elsif option user-class-identifier = "xNBA" and option
client-architecture = 00:09 {
supersede server.filename =
"http://${next-server}:80/tftpboot/xcat/xnba/nodes/adano43.uefi;;
} elsif option client-architecture = 00:07 {
supersede server.filename = "xcat/xnba.efi";
} elsif option client-architecture = 00:00 {
supersede server.filename = "xcat/xnba.kpxe";
} else {
supersede server.filename = "";
}
}
So to figure it out, someone knows from where xCAT grabs the variable to
replace with the next-server? I know that this should be the management node or
maybe a service node, if I was using one.
Thanks,
V.
