\*(L"netstat\*(R" command. .PP Netstat can be called with \f(CW\*(C`\-n\*(C'\fR (show raw \s-1IP\s0 addresses and port numbers instead of hostnames or port names) or without. It can be called with \f(CW\*(C`\-a\*(C'\fR (show all listening and non-listening socket) option or without. And can be called with \&\f(CW\*(C`\-p\*(C'\fR (show PID/program names) or without. .PP This function is not exported by default, but exportable. .PP Arguments ('*' denotes required arguments): .IP "\(bu" 4 \&\fBoutput\fR* => \fIstr\fR .Sp Output of netstat command. .IP "\(bu" 4 \&\fBtcp\fR => \fIbool\fR (default: 1) .Sp Whether to parse \s-1TCP\s0 (and \s-1TCP6\s0) connections. .IP "\(bu" 4 \&\fBudp\fR => \fIbool\fR (default: 1) .Sp Whether to parse \s-1UDP\s0 (and \s-1UDP6\s0) connections. .IP "\(bu" 4 \&\fBunix\fR => \fIbool\fR (default: 1) .Sp Whether to parse Unix socket connections. .PP Returns an enveloped result (an array). .PP First element (status) is an integer containing \s-1HTTP\s0 status code (200 means \s-1OK,\s0 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or '\s-1OK\s0' 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. .PP Return value: (any) .SH "HOMEPAGE" .IX Header "HOMEPAGE" Please visit the project's homepage at . .SH "SOURCE" .IX Header "SOURCE" Source repository is at . .SH "BUGS" .IX Header "BUGS" Please report any bugs or feature requests on the bugtracker website .PP When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. .SH "AUTHOR" .IX Header "AUTHOR" perlancar .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2017, 2015, 2014, 2012, 2011 by perlancar@cpan.org. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
