Re: [BackupPC-users] multiple IP for the same host

[Jack C. <jc...@vc...>]

If you have your own (versus an appliance) DHCP server, you could code
the DHCP to resolve both of the same ether addresses to a single IP
address.  Just make sure to NOT use BOTH at the same time on your
laptop. (unless you figure out how to do the old 'shotgun' or bonding
kind of network things to give you the bandwidth of both ... ugh)
