I am just wondering if there is a known problem with split(). I have tried
to locate a bug report tracking system on-line to vrfy this before asking,
but failed to do so. Anyways the problem..

  ($website,$logdata) = split(/​:/, $newmsg, 2);

the input line is :
www.calweb.com​:207.211.93.239 - - [27/Jul/1999​:16​:41​:50 -0700] "GET / HTTP/1.0" 200 6512

$logdata is printed out to another file, but there are about 200 out of
225534 with the www.calweb.com​: still in them. Comparing the input line vs
whats in the output file, with od, and the lines are the same, so no random
chars in there screwing it up. I will put the entire code at the bottom of
this msg if it helps any more..

Thanks!!

#!/usr/bin/perl

require "cacheout.pl";
#use strict;
use IO​::Socket;
my($sock, $newmsg, $hisaddr, $hishost, $MAXLEN, $PORTNO, $website, $lastwebsite, $logdata);
$MAXLEN = 1024;
$PORTNO = 5151;
$sock = IO​::Socket​::INET->new(LocalPort => $PORTNO, Proto => 'udp')
  or die "socket​: $@​";
print "Awaiting UDP messages on port $PORTNO\n";

open INLOG, ">>inputlog";

while ($sock->recv($newmsg, $MAXLEN)) {

#net stuff
# my($port, $ipaddr) = sockaddr_in($sock->peername);
# $hishost = gethostbyaddr($ipaddr, AF_INET);

Looks like a bug in your script. Since MAXLEN is 1024, you are
presumably reading more than one record on occasion.
