I use the unix command tcpdump with these extensions -A -s0 -ien0 port 80

I know how to add, for example a new host, that would be and \ host random.com

Can I sniff for certain filetypes? I have tried filetype xml, but that doesn't work, there must be a way to do this? Or can I at least make it more easily human readable?

But that still output things like this:

[email protected]............@win-concon-2---s...@@...@@
http 172. static..@@

And some every (25)? line there is something useful.

tcpdump has no understanding of file types, see man pcap-filter for the expressions it understands. And I have no idea what exactly you want to have more human readable - maybe you should just switch to wireshark for a more comfortable interface.
