| # executed by udhcpc |
| # parameters: $1 and environment |
| # $1 is: |
| # |
| # deconfig: udhcpc starts, or lease is lost. |
| # Environment example: interface=eth0 |
| # |
| # bound: lease is obtained. Environment example: |
| # dhcptype=5 |
| # serverid=172.16.42.102 |
| # lease=97200 |
| # interface=eth0 |
| # ip=172.16.42.177 |
| # subnet=255.255.255.0 |
| # mask=24 |
| # broadcast=172.16.22.255 |
| # router=172.16.42.98 |
| # dns=10.34.32.125 10.32.63.5 10.34.255.7 10.11.255.27 |
| # domain=lab.example.com example.com |
| # ntpsrv=10.34.32.125 10.34.255.7 |
| # |
| # renew: lease is renewed. Environment is similar to "bound". |
| # The IP address does not change, however, the other DHCP paramaters, |
| # such as the default gateway, subnet mask, and dns server may change. |
| # |
| # nak: udhcpc received a NAK message. |
| # Environment example: interface=eth0 |
| # |
| # leasefail: udhcpc cannot obtain a lease (DHCP server not responding, etc). |
| # Environment example: interface=eth0 |
| |
| # TODO: put $domain into /etc/resolv.conf (thru /var/service/fw) |
