Interesting! Thank you: I'd previously missed this part of the pf.conf(5) manpage which explains: ] When the interface name is surrounded by parentheses, the rule is ] automatically updated whenever the interface changes its address. The ] ruleset does not need to be reloaded. This is especially useful with ] NAT. I'll have to give it a try. -- Mark

You could write a script around "route monitor" (in a while loop) to get notified when you get a new address assigned to the interface. Another possibility is to use dhclient with option -L in combiantion with a tool like entr (in ports) to react on file changes. Remi

Looking at the man page this might be a way to do what I want. > ...just need to sort out the macro language in man ifstated.conf ;^) ifstated looks at the physical link of an interface. In ifconfig output this is the line starting with status. This state does not change when a new address is assigned to an interface. Remi

Hi Duncan, Not sure if I understood you correctly but doesn't send host-name ... in dhclient.conf(5) do what you want? Regards, Raf
dhclient.conf and hostname.if
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Back when the script tag was removed from dhclient.conf the functionality to do external commands was ostensibly moved into hostname.if via the !command mechanism. in man hostname.if it says "It is worth noting that ``\$if'' in a command line will be replaced by the interface name" Is there any similar tag to access the addess assigned by dhcp? What other mechanisms exist to update dynamic dns assignments?
