iptraf saves it’s settings in a config file
/var/local/iptraf/iptraf.cfg
But zeroshell doesn’t create the directory it needs.
So do this:
mkdir /var/local/iptraf
It will be gone at the next zeroshell reboot, so it probably needs to be added to the bootup scripts.
I use iptraf via a ssh connection to zeroshell.
I set Configure–> Timers –> Screen update interval –> 1 second. Otherwise, iptraf itself continuously generates a lot of packets when you monitor the ETH that your ssh session is running on. (it’s not a problem on the console)
