Live network statistics through SSH?
-
Hi!
I just bought a Raspberry Pi (my second, actually) and i was thinking of settting up an extra monitor and view live network statistics through SSH from my Pfsense router (and the RPI as a client). The problem is that i'm a FreeBSD newbie.
Earlier i have tried the "top" syntax which works somewhat, but it would be alot better with graphs or at least more detailed network statistics such as current in/out, states and so forth. Does anyone know such a tool which is pretty easy to install (or already in Pfsense) that does this?

You could use the ntop package via the webUI to do it, and there is also Stauts->Traffic Graphs.
I prefer to use the widgets on the pfSense webUI. Add what you need and there's a pretty good dashboard of what's going on with the firewall.

you can install the vnstat
vnstat -i em0 Database updated: Tue Apr 2 16:13:01 2013 em0 since 04/29/12 rx: 185.76 GiB tx: 866.99 GiB total: 1.03 TiB monthly rx | tx | total | avg. rate ------------------------+-------------+-------------+--------------- Mar '13 9.00 GiB | 87.41 GiB | 96.41 GiB | 301.94 kbit/s Apr '13 133.70 MiB | 1.96 GiB | 2.09 GiB | 120.98 kbit/s ------------------------+-------------+-------------+--------------- estimated 2.33 GiB | 35.04 GiB | 37.36 GiB | daily rx | tx | total | avg. rate ------------------------+-------------+-------------+--------------- yesterday 87.76 MiB | 1.53 GiB | 1.62 GiB | 157.09 kbit/s today 45.94 MiB | 435.36 MiB | 481.30 MiB | 67.54 kbit/s ------------------------+-------------+-------------+--------------- estimated 66 MiB | 643 MiB | 709 MiB |vnstat -i em0 -h em0 16:15 ^ t | t | t | t | t t | t t | t t t | t t t | t t t | t t t -+---------------------------------------------------------------------------> | 17 18 19 20 21 22 23 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 h rx (KiB) tx (KiB) h rx (KiB) tx (KiB) h rx (KiB) tx (KiB) 17 1740 1512 01 2004 2026 09 2985 4467 18 2361 1750 02 1806 2564 10 3144 4573 19 19643 752533 03 1749 2254 11 2658 3488 20 1927 2817 04 1841 1851 12 2729 2079 21 1892 1809 05 2032 1835 13 1841 1673 22 4621 40680 06 1912 2714 14 2126 2868 23 16816 467654 07 10062 355653 15 1818 1691 00 4467 44405 08 3445 11285 16 496 444 [2.1-BETA1][admin@pfsense.local.lan]/root(12):trafshow might be what your looking for?

Thanks for the answers, i had totally missed the Pfsense page with monitoring software. Nice!

If you want to watch traffic realtime, use iftop. There's no formal package for it yet, since it's only usable from the console, but it's great for tracking down abusers while traffic is flowing.

Would you not be better off using pfflowd to export traffic data to some netflow analyser running on the Pi?
I imagine you would end up with a set of pretty screens! :) I don't know if the Pi has enough horsepower to do that. Fortunately there are so many people using them I'm sure someone has already tried.Steve
