Ein Skript, das tcpdump verwendet:
#!/usr/bin/perl
$LIMIT= shift || 50;
$|=1;
open(STDIN,"/usr/sbin/tcpdump -lnx -s 1024 dst port 80 |");
while (<>){
if(/^\S/){
last unless $LIMIT--;
while($packet=~/(GET|POST|WWW-Authenticate|Authorization).+/gx){
print "$client -> $host\t$&\n";
}
undef $client;
undef $host;
undef $packet;
($client,$host)=/(\d+\.\d+\.\d+\.\d+).+ > (\d+\.\d+\.\d+\.\d+)/x if /P \d+:\d+\((\d+)\)/ && $1 > 0;
}
next unless $client && $host;
s/\s+//;
s/([0-9a-f]{2})\s?/chr(hex($1))/eg;
tr/\x1F-\x7E\r\n//cd;
$packet .=$_;
}
