FUNCTIONS
parse_netstat
Usage:
parse_netstat(%args) -> [status, msg, result, meta]
Parse the output of FreeBSD "netstat" command.
Netstat can be called with "-n" (show raw IP addresses and port numbers instead of
hostnames or port names) or without. It can be called with "-a" (show all listening and
non-listening socket) option or without.
Tested with FreeBSD 10.1's netstat.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
• output* => str
Output of netstat command.
• tcp => bool (default: 1)
Whether to parse TCP (and TCP6) connections.
• udp => bool (default: 1)
Whether to parse UDP (and UDP6) connections.
• unix => bool (default: 1)
Whether to parse Unix socket connections.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller
error, 5xx function error). Second element (msg) is a string containing error message, or
'OK' if status is 200. Third element (result) is optional, the actual result. Fourth
element (meta) is called result metadata and is optional, a hash that contains extra
information.
Return value: (any)
