This doesn't have anything to do with the version of FreeBSD he is 
running. I assume from the fact that he connects with an ethernet cable 
that he is using a dsl modem/router which negotiates the connection and 
if necessary will be running ppp. In that case, there is no need for him 
to run ppp.

No, that means you don't have to run dhcp client.

Yes, ping is possible under unix. Try pinging a known numeric ip address 
first. If that doesn't work, you have a routing/connectivity problem. If 
it does, and you can't then ping a hostname like www.yahoo.com, you'd 
want to check your nameservers listed in /etc/resolv.conf

To start with, assuming that 12.103.21.1 is your dsl router (and it 
needs to be for your configuration to have any chance of working), can 
you ping that? Next, can you ping, say, 12.127.16.83?

I don't know what this means.

There's no default route. You can try setting one explicitly on the 
command line but you really want a solution that will survive reboots. 
If you've been mucking about with ifconfig type statements, try a reboot 
to clear the air, then the ping tests (numeric ip of router - numeric ip 
of nameserver - hostname).

I would also recommend you set a proper hostname in /etc/rc.conf - 
preferably a real one...
