Well here is the results of my attempts to connect to Time Warner
cable network.
After 4 calls to their call center which was in the Philippines where
all the people just read a scripted answer FAQ and only had the
ability to remotely reset the modem. I finally requested to talk to
the top support level in the USA. Finally got a tech support person
who knew something about how their network was configured.
Their modems at power up time run a script that is really a private
LAN using 192.168.x.x to auto verify the cable modem mac address
against a table of authorized accounts. At the conclusion the 10.2.0.1
dhcp server issues a real routable ip address along with the routable
2 dns ip address.
Now this long duration hand shake takes about 40 seconds and on a
windows system, windows keeps looping through the ip and dns acquire
code until it succeeds. Now on freebsd the ifconfig_fxp0="DHCP" seems
to only cycle a single time and results in a "no carrier" status in
the boot up msg log.
After the Freebsd 8.2 boot process completed and I saw "no carrier"
status i issued "/etc/rc.d/netif restart" command which resulted in
the same status. This is when I posted to the questions list for help.
It was after the post that I had my conversation with the level 3 tech
support guy and learned about the long hand shake process. I next
tried issuing (ifconfig fxp0 up) after the freebsd boot process
completed and to my surprise I had a public routable ip address. So I
have to find a way during the boot process to give the
ifconfig_fxp0="DHCP" statement in the /etc/rc.conf some delay time.
But I think Freebsd 9.0 has an built in "up" process in its boot up
process that may solve this problem.
Another thing I learned from the level 3 support guy is that the cable
modem has to be reset by unplugging it's power if I want to move the
output cable to a different device, such as from the window box
to the freebsd box or to a router.
The bottom line is I have things working now and there was nothing
wrong with either my window box or my freebsd box. Its just the Time
Warner cable modem box and the non-standard way it's configured.
I had my suspicions, but I had no way to actually know. Cable modems
work the same here: they become 'attached' to a given mac address and
have to be reset when moved to a new device. Best to use a router to
save that one.
Simply unplugging and plugging in the cable should have told FBSD to
reconfigure that network.
Providing more complete information to the list for help may have given
you the solution sooner.
