    Introduce log and save functions · 472b841e
    Dimitris Aragiorgis authored
    
    The save() function is used in order to save and backup
    iptables/arptables/ebtables commands related to each interface.
    
    The log() function is a wrapper of snf-network-log script.
    
    Do not use a default variable for the log script. This could
    cause a fork bomb if the admin forgot to define it.
