What are the system requirements for BlockHosts?
Sun, 2007–Apr–08
- Linux-like systems. Not usable on Microsoft Windows.
- Python 2.3 or later, with the optparse module.
- Primarily uses host control facility and related files such as hosts.access. If not using TCP/IP blocking (--iproute or --iptables options to blockhosts.py), then the extensions to the access control language as described in the man 5 hosts_options page are required, which allow use of :allow and :deny keywords. ["...extensions are turned on at program build time by building with -DPROCESS_OPTIONS..." for services like ssh, ftp, etc]
- If not using host control facilities (tcpd, hosts.access, etc),
then there needs to be a way to trigger the run of blockhosts.py, or blockhosts.py should be run periodically using cron. Secondly, there must be some way to update a file to list the blocked ip (for example, hosts.access file, or Apache .htaccess file, etc). Alternately, all TCP/IP communication can be blocked by using the --iproute or --iptables options of blockhosts.py
