I just wanted to share the perl script i wrote to find duplciate unique IDs in Sophos. It scans the IIS logs looking for duplicate GUIDs.
#Stephen
#Check for Duplicates
use Data::Dumper;
$file = "\\\\sophos-c108-01\\W3SVC1\\u_ex110822.log";
my %hash = ();
my %hDup = ();
open FILE, $file or die $!;
while (<FILE>)
{
@data = ($_ =~ /(\b143\.55\.\d{1,3}\.\d{1,3}\b).*?(\b143\.55\.\d{1,3}\.\d{1,3}\b).*?(\{{0,1}[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}{0,1})/);
#print $data[0] . "\n";
if ((exists $hash{$data[2]}) && ($hash{$data[2]} ne $data[1]))
{
if(not exists $hDup{$data[1]})
{
print $data[1] . "\n";
$hDup{$data[1]} = $data[1];
}
}
else
{
$hash{$data[2]} = $data[1];
}
}
close(FILE); I have more info on my blog about it.
