While trying to configure ntp, I discovered that my IPv4 loopback was
not being configured. I can manually restart it with 'ifconfig lo0
add 127.0.0.1', however, it does not survive a reboot.
Here's the output of ipconfig following boot:
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:08:54:dd:65:8d
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet6 ::1 prefixlen 128
and after manually configuring:
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:08:54:dd:65:8d
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet6 ::1 prefixlen 128
inet 127.0.0.1 netmask 0xff000000
What do I need to configure to get it to come up at bootup? Any
thoughts as to why it disappears?
(I'm running FreeBSD 6.2 stable, downloaded and installed about 3 wks ago).

there's cleaner space out here to roam
