Ok, got a new cable modem. Pretty good so far. Now, I just need to get
the DHCP client working. Haven't gotten too lucky with that so far.
First, I just put the line
ifconfig_xl0="DHCP"
in rc.conf.
That did something. Resolv.conf looked good and the leases file in
/var/db looked tremendous. But routing didn't work. Couldn't ping
anything: nameservers, the supposed default routers or anything.
Then, to get something in the log files, I tried starting the dhclient
manually. Now, I see this:
mursu dhclient: New Network Number: 213.243.154.0
mursu dhclient: New Broadcast Address: 213.243.155.255
mursu dhclient: New IP Address (xl0): 213.243.155.19
mursu dhclient: New Subnet Mask (xl0): 255.255.254.0
mursu dhclient: New Broadcast Address (xl0):213.243.155.255
mursu dhclient: New Routers: 213.243.154.1
in /var/log/messages.
This looks promising. But the routing tables don't. This is what I see
with netstat -rn:
Internet:
Destination Gateway Flags Refs Use Netif
Expire
127.0.0.1 127.0.0.1 UH 2 232 lo0
127.53.0.1 127.53.0.1 UH 1 2 lo0
213.243.155.19 127.0.0.1 UGHS 0 0 lo0
And ifconfig gives:
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3<rxcsum,txcsum>
inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
ether 00:a0:24:55:02:24
media: Ethernet 10baseT/UTP
status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
inet 127.53.0.1 netmask 0xffffffff
If I ping the supposed default router 213.243.155, I see:
PING 213.243.155.1 (213.243.155.1): 56 data bytes
ping: sendto: No route to host
ping: sendto: No route to host
And when I ping 213.243.155.19, I see strange things:
...
36 bytes from localhost (127.0.0.1): Redirect Host(New addr: 127.0.0.1)

....
(Looks like the modem is alive)
So, the question is: What knob must I turn to get dhclient to set the
default route properly? Otherwise the setup look reasonable.
