Step 1 Create Database and Tables in MySQL Add a “source” field for the server name if you want to use a remote database setup (and add it to the UNIQUE KEY).The UNIQUE KEY prevents duplicates of course. But this means you can refresh the perl script without handling duplicates there which would complicate things considerably. CREATE TABLE iptable (...

Three (3) steps to completely eliminate IPV6 on your system. Step 3 applies only if you are using SSH in daemon mode (on a server). The following should work for all Debian. Step 1 Step 2 Step 3
To disable IPv6 on all interfaces system wide sudo vi /etc/sysctl.conf add this line net.ipv6.conf.all.disable_ipv6 = 1 Or To disable IPv6 on an interface only net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.eth0.disable_ipv6 = 1 sudo sysctl -p /etc/sysctl.conf or reboot
