I would like to manually try to connect to my isp before i try changing the

for DHCP.
I got my network info from my lrp operating system. I would like to switch

to bsd.
can i use traceroute to find out the number of hops i am currently taking to

to my isp's dhcp server?
Had another thought, can you traceroute from the machine that is properly
connecting? Are you sure that you can't get an IP address because of the
TTL? I find it very odd that the DHCP server would be that far away, but
stranger things have happened.
manual configuration
--------------------
ifconfig_rl0="inet 66.41.139.87 netmask 255.255.248.0" #66.41.139.87/21
ifconfig_rl1="inet 192.168.1.254 netmask 255.255.255.0"
default_router="66.41.136.1 rl0"
This should be:
defaultrouter="66.41.136.1"
default_router="192.168.1.254 rl1"
^^^^^^^^^^^^^^^^^
This is wrong. Don't put that in.
Bill,
Why do i not need to have two default routes, I have 2 networks? I am sure you
are correct, I guess i just don't understand why.
A "default route" or "default gateway" is defined as the place the software
sends traffic when it doesn't know how else to reach the machine in question.
The assumption is that the "default route" computer will know where to send it.
Other routes are added automagically, without needing your intervention. For
example, when you ifconfig the rl1 interface, the network software automatically
adds a route to 192.168.1.*, based on the IP/netmask that you configured. The
network software then knows that all computers in that range can be reached
through that network card.
Additionally, having a default route that points back to itself results in an
infinite loop (if the machine will even let you do it). The effect is: machine
doesn't know how to reach host, so sends to default route, doesn't know how
to reach host, sends to default route. It just keeps receiving the same traffic
that it doesn't know what to do with.
is there a way i can find out
the ip addr of my dhcp server?
Call your ISP, or if you have a machine that is working properly, check where
it got it's IP address. Most OSes will tell you (even Windows).
does this even work: default_router="192.168.1.254 rl1"
No. "default_router" is a syntax error, it should be "defaultrouter" and
the interface name at the end is not supposed to be there. The system will
automagically determine the interface that belongs to the route.
