Traffic by IP
-
I'd like to know what the best method to monitor traffic by IP is so I will know who is using the majority of the bandwidth.
I would like something that also can email me notifications if I prefer.
-
you can use the bandwithd which will show usage on ipbasis
-
Ntop will do that for you, install the package.
I have grown to love ntop.
Here is a pic of ntop on my lan.
-
My ntop is crashing. Lots of other people have the same problem. Did you do something to make it work?
-
I would be interested too how to fix ntop. On two different networks (and pfsense boxes) ntop crashes couple minutes after start.
Using versions 1.2.1-rc2 and 1.2.3. Both networks have quite the different kind of traffic and user amounts so it probably doesnt have anything to do with two much traffic/hosts to track
-
How much RAM do you have in these boxes?
ntop is a ressource hog! -
512 with 180 allocated to squid. Also running vnstat and imspector. I will try fiddle with the settings to see if it would get more stable (meaning taking some ram away from squid).
-
I run with no less the 512. The reason being is that with 512 you have elbow room. Currently on my system I am using 212MB of RAM. I have a P4 1.6 w/512 MB ECC RIMMs. Might I also add I love running PfSense on RIMMs. It seems the interface alone runs faster, not sure about everything else ;)
But I prefer to run PfSense on ECC RAM being that this is a network critical machine and as far as I'm concerned errors are not acceptable.
Anyhow, I'm running for packages….
darkstat
squid
squidGuard
FreeRADIUS
imspector
nut
snortAny my system does very well and is very stable. Sometimes I use as much as 350MB of RAM but it's not often, that may have been when I was load balancing w/failover
