What is the best for Packet Sniffer
 

I am setting up a packet sniffer, I know about ethreal, but i am wondering if there are anymore good ones that people know about, so maybe i can use more then one. Thanks.

its a little tough to use, but tcpdump is wonderful.

anymore, anything?

Well, tcpdump and ethereal work fine if you just want to intercept all the packets going across your network. If you wanted to take it further and analyze the packets you'd want to use something like snort. Snort is an Intrusion Detection System. Its extremely robust has many features like logging all the packets to a database and graphing packets for you.

Their is also things like ipcop which is an entire distro used to setup a firewall. Ipcop has snort built in as a module so it can do packet sniffing if you want.

Perhaps these options are too complex for what you are looking for. I'm not sure exactly what you want to do but these are some alternatives.

Thanks that is great. I like those anymore like that more robust or less robust

that is great thanks
