I don't think it needs to be expanded by xCAT in the DHCP lease file. dhcpd will literally send the "http://${next-server}:80/tftpboot/xcat/xnba/nodes/adano43"; string in the DHCP reply, and the TFTP/PXE client will interpret this using the "next-server" value that is defined at the subnet level in dhcpd.conf.
Some examples here: https://wiki.alpinelinux.org/wiki/PXE_boot#HOWTO Cheers, -- Kilian On Fri, May 21, 2021 at 4:51 PM Vinícius Ferrão via xCAT-user <xcat-user@lists.sourceforge.net> wrote: > > Hello, I'm running xCAT development build and makedhcp is falling to proper > populate next-server on /var/lib/dhcpd/dhcpd.leases: > > As an example: > > host adano43 { > dynamic; > hardware ethernet 00:11:22:33:44:55; > uid 00:11:22:33:44:55; > fixed-address 172.26.0.43; > supersede server.ddns-hostname = "adano43"; > supersede host-name = "adano43"; > if option user-class-identifier = "xNBA" and option > client-architecture > = 00:00 { > supersede server.always-broadcast = 01; > supersede server.filename = > "http://${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?
