A simple solution might be to write something in the postup() and |
| 12 |
postdown() functions in /etc/conf.d/net. |

For something more complicated, if you use the dhclient program from the |
| 15 |
dhcp package as your DHCP client, you can modify |
| 16 |
/etc/dhcp/dhclient-exit-hooks script to do whatever you would like |
| 17 |
whenever the DHCP client changes something (due to a release, renew, |
| 18 |
etc). I use it to dynamically setup WINS servers and DNS forwarders for |
| 19 |
whatever network I am plugged into. In this script you will have access |
| 20 |
to all DHCP options provided by the DHCP server. |
