Hi all,

I need an utility to fetch GET, POST, and AUTH payloads. I started searching around, and I found this code, and that's exactly what I need. However, I didn't manage to make the output to be one-lined, as Lincoln showed in the forementioned page.
The code:
#!/usr/bin/perl $LIMIT = shift || 5000; $|=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).+/g) { print "$client -> $host\t$&\n"; } undef $client; undef $host; undef $packet; ($client,$host) = /(\d+\.\d+\.\d+\.\d+).+ > (\d+\.\d+\.\d+\.\d+)/ 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 .= $_; }

I do get some output, but sliced, as if the "line builder" above didn't work.

I found this thread on Perlmonks on the same subject, which happens to have a very similar example. When trying that one, I don't get any output at all.

My OS: Slackware GNU Linux 10.0

Any help is appreciated. Cheers.

EDIT: Here's the output I'm getting when using the above code.
