Hello,

What is a good sniffer for bsd server? I would like to see all data in my LAN. It should be clearly understandable for novice bsd user (me) :)

thank you for advice.

Run tcpdump(1) get data about port # 80 (httpd server)
Code:
tcpdump -n -i ${interface} -s 0 -w ${output.file} src or dst port 80
and Use gui tools such as net/wireshark (which is both network analyzer that lets you capture and interactively browse ) to see data later on. Usually servers do not have GUI installed so use tcpdump and wireshark combo.

novice user + sniffer = no good
if you are novice, thus no understanding of network protocols, why you need sniffer?

Maybe sniffing is the wrong place to start when analysing LAN traffic, because it presupposes an in-depth knowledge of network protocols. You'd be much better served with something like net/ntop which will show you traffic flows and graphs in a web interface.
