Anti-spam system that helps minimize the amount of spammers that connect to your server by banning their ip's using one of the ip text databases provided by stopforumspam.com. Also the script can optionally fetch the spamhaus.org ip list text files. Stop Spam also keeps these text databases updated by periodically downloading latest version from the website or any other url that you set on the configuration file.

To keep the iptable rules minimal, the script bans every ip that is found to be used for spamming for a predefined period of 10 minutes. After the 10 minutes are due the ip is unbanned in order to minimize the amount of rules actively used.

• Auto updates the spam ip database
• On the fly banning of spam ip's
• Keeps iptable rules clean
• Whitelisting of ip's and hosts
• IPv6 support

As root user execute the following commands:

wget https://github.com/jgmdev/stopspam/archive/master.zip -O stopspam.zip
unzip stopspam.zip
cd stopspam-master
./install.sh

As root user execute the following commands:

cd stopspam-master
./uninstall.sh

The installer will automatically detect if your system supports init.d scripts or systemd services. If one of them is found it will install apropiate files and start the stopspam script.

Once you have Stop Spam installed proceed to modify the config files to fit your needs.

/etc/stopspam/white.ip.list

A list of ipv4 or ipv6 ip's to white list.

/etc/stopspam/white.host.list

A list of domains/hosts to white list.

/etc/stopspam/stopspam.conf

The behaviour of the stopspam script is modified by this configuration file. For more details see man stopspam which has documentation of the different configuration options.

After you modify the config files you will need to restart the daemon. If running on systemd:

systemctl restart stopspam

If running as classical init.d script:

/etc/init.d/stopspam restart
or
service stopspam restart
