blockdomains - block list file format

/etc/blockdomains/acl/blocklist.acl

ln -s ../acl/blocklist.acl /etc/blockdomains/blocked/

blockdomains uses one or more block list files which contain declaratios of the domains to block, one domain per line that starts with any number of whitespace characters followed by a period (".") before the domain to block. The blocking applies to the domain and all its sub domains.

Anything not starting with a period (".") is a comment and leading whitespace is ignored. Block list domains start with optional whitespace and a period, followed by the domain name to block, optionally followed by a whitespace and a comment. Like the following:

Example of block list



  .bad.domain.com -- domain name up to whitespace is blocked
Blank lines are fine too; they treated as comments. The block list
domains don't need to be column aligned. So, here is another:
.another.domain.to.block
End of block list example.
