Logging traffic in Beta 2.0



  • Hello,

    how to log all estabilished connections in pfSense? I would like to dump data to single file everyday on multi WAN setup. It should has: when estabilished, when ended, IP+MAC of station in LAN, should take care for which WAN was outgoing, and if possible - send/received data for everyhost (daily). Is somewhere such module for pfSense?
    On simple linux I think it would be like this script (bond0 is interface for LAN):

    #!/bin/bash
    #Check if directory exists
    if test -d /home/logi/
            then echo "Directory already exists!"
            else  mkdir /home/logi
            fi
    #Change filename
    mv /home/logi/tcp-syn.dmp /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.dmp
    #Dump as text
    tcpdump -i bond0 tcp [13] == 2 -n >> /home/logi/tcp-syn.dmp & tar cvfz /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.tar.gz /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.dmp /
    rm /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.dmp
    

    this can be also RAW data (to avoid modifications in logs):

    tcpdump -i bond0 tcp [13] == 2 -w /home/logi/tcp-syn.dmp & tar cvfz /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.tar.gz /home/logi/tcp-restart-`date +%d-%B-%Y--%H-%M`.dmp

    Sounds like you want to run netflow (either with the pfflowd or softflowd packages) - but it doesn't queue the data locally, you need a netflow collector to receive the data and store it.
