Hi,

I upgraded from 8.0 stable to 8.2 stable today. Now I can't connect to the network through the network adapter. I've set DCHP and SYNCDHCP in /etc/rc.conf and it worked in 8.0. It seems the dhclient problem. The ip address can't be obtained.

When I run 'dhclient em0' manually, it shows that an ip address is leased. But actually it is not. The 'ifconfig em0' always shows an address of 0.0.0.0 with active status.

$dhclient em0
DHCPREQUEST on em0 to 255.255.255.255 port 67
DHCPACK from 192.168.3.1
bound to 192.168.3.39 -- renewal in 43200 seconds

But

$ifconfig em0
em0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
         ether 6c:62:6d:03:16:31
         inet 0.0.0.0 netmask 0xffffff00 broadcast 255.255.255.255
         nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
         media: Ethernet autoselect (10baseT/UTP <half-duplex>)
         status: active

Any help would be appreciated.

Xihong
