Two big things to bet aware of is this module does not currently resulve names and this module |
39
|
|
|
|
|
|
|
does not handle unix sockets. Unix sockets will just be skipped over. |
40
|
|
|
|
|
|
|
|
41
|
|
|
|
|
|
|
The connection hashes returned differ from Parse::Netstat slightly. Below is what a standard ones |
42
|
|
|
|
|
|
|
for IPv4/6 looks like. |

This module has two additional keys, "local_pp" and "foreign_pp". Which contains and data |
56
|
|
|
|
|
|
|
after % in a address. So "fe80::1%lo0" would be split into "fe80::1" and "lo0" as in the |
57
|
|
|
|
|
|
|
example below. |
