Thank you to Kris and Tyler for your suggestions.

 

Both of you suggested using a DNS server rather than the hosts file. In fact, I had already set up BIND DNS on the server (mostly properly I believe), so I merely removed all the references to the laptops from the hosts file without making any changes.

 

Next week when all the laptops are back in the office I will test that all works as planned.

It is also simple enough to run DNSmasq on your BackupPC box.  Setup is REALLY easy.

 

 

^ has the man pages, but the /etc/dnsmasq.conf file is well documented.

Hi Paul,

What you want is DNS. I use an embedded router which runs DNSmasq. This
provides both DHCP and DNS. It always matches hostnames (from DHCP
requests) to DNS names, as well as reverse records. Thus my BackupPC
server can just look for "ssss12" and find it, on whatever IP it has.
You might consider it. You can do the same setup with BIND and DHCPd,
but it is a lot more work to set up.

The alternative is to use BackupPC's "DHCP" setting
in /etc/backuppc/hosts. This causes BackupPC to scan the IP range for
the host itself.

Regards,
Tyler
