Method: Puppet::Util::Firewall#string_to_port

Defined in:

lib/puppet/util/firewall.rb

#string_to_port(value, proto) ⇒ Object

This method takes a string and a protocol and attempts to convert it to a port number if valid.

If the string already contains a port number or perhaps a range of ports in the format 22:1000 for example, it simply returns the string and does nothing.
