Hari Sekhon - Perl Library

Perl library, full of lots of validation code and utility functions.

Needed for a lot of the programs I've written over the years. In fact my current main library was actually cobbled together from lots of pieces of code I wrote over the years since I found myself reusing common things over and over. This drastically reduces the amount of code and effort required to write new robust well validated code which is why it's used extensively throughout the portions of code you'll find on my GitHub account, especially all the Advanced Nagios Plugins Collection which I've been developing for many years since 2006

Build + Unit Tests

make &&
make test

Continuous Integration is run on this repo to build and unit test it (Test::More, almost 800 unit tests).

Configuration

Strict validations include host/domain/FQDNs using TLDs which are populated from the official IANA list, a snapshot of which is shipped as part of this project.

To update the bundled official IANA TLD list with the latest valid TLDs do

make tld

Custom TLDs

If using bespoke internal domains such as .local, .intranet, .vm, .cloud etc. that aren't part of the official IANA TLD list then this is additionally supported via a custom configuration file resources/custom_tlds.txt containing one TLD per line, with support for # comment prefixes. Just add your bespoke internal TLD to the file and it will then pass the host/domain/fqdn validations.

IO::Socket::SSL doesn't respect ignoring self-signed certs in recent version(s) eg. 2.020

Recent version(s) of IO::Socket::SSL (2.020) seem to fail to respect options to ignore self-signed certs. The workaround is to create the hidden touch file below in the same top-level directory as the library to make it include and use Net::SSL instead of IO::Socket::SSL.

touch .use_net_ssl
