- it() a hostname. The hostname as determined by a reverse lookup will
- be matched (case insensitive) against the pattern. Only an exact
- match is allowed in. This only works if "reverse lookup" is enabled
- (the default).
- it() a hostname pattern using wildcards. These are matched using the
- same rules as normal unix filename matching. If the pattern matches
- then the client is allowed in.
