Networking Monitor

[Deleted member 2077]

What's a good way to monitor my home network? I have a freebsd router/firewall and everything goes though that.

Optimally I would like something that graphs it over time and also breaks it down by "type" of traffic (udp, p2p, http, etc) so I can get a general feel of what is sucking up all the bandwidth during certain times of the day (I have room mates). Also source would be good too.

You definitely want to look at /usr/ports/net/ntop.

Hi, rolfheinrich is right. Generally there is many apps, which can do exactly what You want. A good source of information could be ports/net-mgmt page. I can recommend e.g. (for more information please check the official websites)

• net-mgmt/iftop which "does for network usage what top(1) does for CPU usage"
• net-mgmt/darkstat for traffic graphs, reports etc.
• net/bmon a bandwidth monitor
• net-mgmt/mrtg in short MRTG "is being used to graph all sorts of network devices..." good alternative for bmon
• net-mgmt/etherape - another graphical network monitor.
• net-mgmt/nload some console apps

Of course You can always use system commands like e.g. netstat(1) and many more. I hope, that I helped you and you will find something useful.

Also look into ng_netflow(4), net/pfflowd, and all Netflow data processing/graphing related ports.
