3 | # parameters: $1 and environment |
4 | # $1 is: |
5 | # |
6 | # deconfig: udhcpc starts, or lease is lost. |
7 | # Environment example: interface=eth0 |
8 | # |
9 | # bound: lease is obtained. Environment example: |
10 | # dhcptype=5 |
11 | # serverid=172.16.42.102 |
12 | # lease=97200 |
13 | # interface=eth0 |

21 | # ntpsrv=10.34.32.125 10.34.255.7 |
22 | # |
23 | # renew: lease is renewed. Environment is similar to "bound". |
24 | # The IP address does not change, however, the other DHCP paramaters, |
25 | # such as the default gateway, subnet mask, and dns server may change. |
26 | # |
27 | # nak: udhcpc received a NAK message. |
28 | # Environment example: interface=eth0 |
29 | # |
30 | # leasefail: udhcpc cannot obtain a lease (DHCP server not responding, etc). |
31 | # Environment example: interface=eth0 |

33 | # TODO: put $domain into /etc/resolv.conf (thru /var/service/fw) |
