I am having a problem getting my FreeBSD laptop to work exactly the way
I want it to. Here is the situation. The machine has a PCMCIA etherent
card in it and might find it self connected to any one of 3 different
networks. In addation I want to be able to dial into my home network
and connect to it using PPP.
Some kind soul sent me a small perl script that I have made a few minor
changes to for the multi netwrk setup here it is.
#!/usr/local/bin/perl
%gateway = ('205.159.77.233' => {
gw => '205.159.77.234',
dns => ['205.159.77.240',
'208.140.99.9',
'198.81.225.1'],
dom => 'fas.com'
},
'222.198.37.141' => {
gw => '222.198.37.254',
dns => ['192.1.37.20'],
dom => 'westvaco.com'
},
'192.168.0.3 -link0' => {
gw => '192.168.0.1',
dns => ['192.168.0.1'],
dom => 'westvaco.com'
},
);
`route delete default 2>&1 > /dev/null`;
foreach $key (keys(%gateway))
{
$thiskey = $key;
$up=1;
`ifconfig ep0 inet $key netmask 0xffffff00 link1`;
unless (system("ping -c 1 $gateway{$key}{gw} > /dev/null"))
{
last;
}
print "Cannot ping $gateway{$key}{gw}\n";
$up=0;
}
if($up)
{
`route add default $gateway{$thiskey}{gw}`;
open RESOLVFILE, "> /etc/resolv.conf";
print RESOLVFILE "domain $gateway{$thiskey}{dom}\n";
foreach $ipnum (@{$gateway{$thiskey}{dns}})
{
print RESOLVFILE "nameserver $ipnum\n";
}
close RESOLVFILE;
if($gateway{$thiskey}{dom} eq 'fas.com')
{
`ypbind beach`;
}
print "Configured for network $gateway{$thiskey}{dom}\n";
}
else
{
print "Cannot find a known network\n";
}
This script is invoked from thee pccard script. Y have put NO in the
sysconfig file for the functions handled by this script. This seems to
work OK. Primarly I have tested it on my home network. Now I am trying
to get the machine to dial up and do aPPP link to one of the computers
on my home network. I have the chat script and all that working and can
get a PPP prompt. I can then telnet to the machine that I have conected
to.
At this point, I can't get to anu other machines on my network, much
less the outsde world. Also somehow in hacking on this I have reached
the point where when brought up on my local network rwho and ruptime
don't work on this machine. As a matter of fact, It sees thother
machines, but not itslef!
Here is the output of netstat -r and ifconfig -a after booting on my
local network.

WhatI think* is going on here, is that there are still some remnants of
the attempts to talk to the non-exustent betworsk. Does this make
sense?
Has anyone else worked through this?
