[ILUG] hash tables

[lbedford at wbtsystems.com]

I have a strange problem in work. I have two machines, one with RedHat 6.0, 
and one with RedHat 5.2. (stock, upgrades haven't gone through yet). They're 
both running whichever version of sendmail came with them, and use 
/etc/mail/popip.db as a hash database to allow relaying from (which is updated 
by poprelayd.pl). It works fine on 5.2, but on 6.0, the perl script and 
sendmail seem to use different versions of the hash files. Sendmail's version 
ends with lots of ÿÿÿÿÿ. The perl script one doesn't.

Anyone know much about hash files and version? The perl script as follows is 
roughly equivalent to the full one, and if I let it create the hash file, it 
works fine.

-----------[ perl script ]------------------
#!/usr/bin/perl -w
use Fcntl;
use GDBM_File;
use POSIX;

tie %db, "GDBM_File", "localip.db",O_RDWR|O_CREAT,0640 ||\
        die "Can't open localip.db: $!\n";

$db{"192.168.1.1"} = "OK";
$db{"193.120.231.1"} = "OK";

foreach $key (sort(keys(%db))) {
        print "$key\n";
}

untie %db;
-------------[ end perl ]-------------------
