Default Network Monitoring Software

Hey Guys

Using OpenBSD 5.1.

Wanting to know if there are any good network monitoring packages that I can use with OpenBSD

Pretty much my plan is.

Customer of mine is getting massive internet bills because someone is in the office, downloading things and what not.

I have heard of a package that can produce reports on which computer is doing the nasty on the network. Not necessarily computer names but just looking for something that can do usage logs

Assuming you have familiarized yourself with Section 15 of the FAQ such that you have a baseline understanding of OpenBSD's package/ports system (the ports(7) manpage also has excellent information...(, most networking-related applications can be found at /usr/ports/net in the ports tree:

http://www.openbsd.org/cgi-bin/cvswe...s/net/#dirlist

Recognize that this is the entire ports tree, so you will be finding information on packages available for -release, -stable, and -current.

A third-party site (not affiliated with the OpenBSD project...) which harvests the information found in the CVS port tree into a form more easily searched is:

http://openports.se/

Recognize that this site also presents information for -current as well. The versions of applications discussed at that site may be more recent than those available for OpenBSD 5.1-release.

Lastly, since you mentioned monitoring in particular, nagios & munin are popular applications available.

You could collect netflow data on the firewall (see pflow(4)) and analyze that for offending IP's. Or for a long term solution perhaps look into restricting outbound traffic with authpf(8).

If they are using torrents, use PF/ALTQ to block/limit torrent bandwidth. Likewise if they're using it for FTP and the company doesn't use FTP as SOP, disable it.

Also of course, the ports
