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. Signed-off-by:Dimitris Aragiorgis <dimara@grnet.gr>
