I was looking at the code in Nas.pm:
sub isOnlinePing
{
my ($name, $nas_id, $nas_port, $session_id, $client,
$framed_ip_address) = @
_;
# No framed-IP address?
return 0 unless $framed_ip_address;
# Build a ping packet
my $p = Net::Ping->new("icmp");
# and send it with a one second timeout
my $ret = $p->ping($framed_ip_address, $Radius::Nas::PingTimeout);
$p->close();
return $ret; # there = 1, not there = 0
}
And it looks like I could pretty easily change this to use an external
ping command. I noticed the standard unix ping has a 10-second timeout
(freebsd), but I can likely work around that. I don't have my camel book
handy, but the success of the ping command is reported in the exit value.
Before I go nuts with this though, can anyone comment on this method of
double-checking the session db? It looks to be my only option with IPass
clients...
Thanks,
Charles
