openbsd_dsniff_scripts

OpenBSD dsniff agent rc scripts

This is a script that will startup, shutdown, and restart dsniff, mailsnarf, msgsnarf and urlsnarf listening agents on OpenBSD routers/firewalls. It also logs their output and rotates the files when they reach 50MB.

NOTE: This will add significant CPU overhead so be careful when/where you run this. For instance, while saturating a 100Mbit link to approximately 50% will produce a CPU load average of about 2 on an embedded device.

By default it logs to /var/log/dsniff/$APPNAME

Usage:

    sudo su -
    mkdir ~/bin
    cd ~/bin
    git clone git://github.com/avatar4d/openbsd_dsniff_scripts.git
    crontab -e

Then add the following:

    0       0       *       *       *       /root/bin/openbsd_dsniff_scripts/sniffer_agents.sh

Then edit the rc.local script:

    vi /etc/rc.local

Then add the following:

   ## start dsniff daemons
   if [ -x /root/bin/openbsd_dsniff_scripts/sniffer_agents.sh ]; then
        echo 'dsniff daemons'
        /root/bin/openbsd_dsniff_scripts/sniffer_agents.sh
   fi
