I am trying to set up my FreeBSD laptop, so that it can connect to
multiple networks and/or also call my home network via ppp. I have the
ppp conection working as far as getting the link up, but I am strugling
with routing.
When the machine boots the folowing perl script is escruted:
#!/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',
yp => 'yes"
},
'222.198.37.141' => {
gw => '222.198.37.254',
dns => ['192.1.37.20'],
dom => 'westvaco.com',
yp => 'no"
},
'192.168.0.3 -link0' => {
gw => '192.168.0.1',
dns => ['192.168.0.1'],
dom => 'westvaco.com',
yp => 'no"
},
);
`route delete default 2>&1 > /dev/null`;
foreach $key (keys(%gateway))
{
$thiskey = $key;
$up=1;
`ifconfig ep0 inet $key netmask 0xffffff00`;
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;
print "Configured for network $gateway{$thiskey}{dom}\n";
}
else
{
print "Cannot find a known network\n";
`/usr/bin/killall ypbind`;
}
Now here is the problem. If the machine is *not* conectedd to any of
these networks, I still get the folowing routing table:
Script started on Thu Dec 25 15:15:06 1997
# netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
127.0.0.1 127.0.0.1 UH 3 203 lo0
192.168.0.1 link#5 UHLW 0 1
205.159.77 link#5 UC 0 0
205.159.77.234 link#5 UHLW 0 1
205.159.77.240 link#5 UHLW 0 11
222.198.37.254 link#5 UHLW 0 1
# ^Dexit
Script done on Thu Dec 25 15:15:14 1997
Now as you can see, I have some pretty strange entries her. For each
one of the networks that I tride I have this mysterios link#5 entry.
route delete refuses to remove these entries. I also have a network
entry for the last network that I tried.
What are these entries, and how do I avoid creating them, or dlete them
after I test for that network ?
Thanks.
