"RedNectar" Chris Welsh likes to share knowledge, so it's no surprise that he spends most of his time teaching, some of his time consulting and too much of his time on forums and blogs. The teaching is mainly Cisco related (he became a CCSI in 1998), the consulting is through his own company (Nectar Network Knowledge) and his blog (http://rednectar.net), along with his contributions to the GNS3 Forum (http://forum.gns3.net), became the inspiration to write this book. To keep his sanity, he likes to go for long walks in bushland, particularly around the National Parks near his hometown of Sydney, Australia.
