I'm possitive this is right (I'll be HIGHLY surprised if it is not), but yeah.
The Radius Authentication perl script operates on the same way... Relavent section
of the perl code....
my $GlobalDB = Mysql->connect(DBHost, DBName, DBUser, DBPass);
$GlobalDB->{'GlobalDB'}->{'PrintError'} = 0;
if ($GlobalDB) {
# This is the main loop for authentication requests
while (<STDIN>) {
chop($_);
my @Info = split(/ /, $_);
my $SQL = $GlobalDB->query("VALIDATE USER ON MYSQL USING $INFO[0] AND $INFO[1]");
if ($SQL->numrows != 1) {
print "ERR";
} else {
print "OK";
}
}
}
The queries never make it to my database. When running the script for testing
purposes, it works...
root@pyro:/usr/local/libexec/squid# /usr/local/libexec/squid/cenergy_auth
<username> <password>
OK^C
Squid does start the perl childs to run the script. I am however doubting that
Squid actually sends the requests off to the script - the scripts never queries
anything to the database when ran from squid ..... :(
