I would like to thank Say Mistage (available on Twitter at @sayomgwtf) for keeping me sane with all of her doodles and inspiration during the writing of this book. Let me say that there are a few people in this world who suffer that never should. These people are often the most inspirational and happy people you find. Say is one of those people who suffers a lot in life but never lets it show.

Manikandan Somasundaram has more than 3 years of experience in the field of Linux administration. He has a Bachelor of Engineering degree in Computer Science. Being a Linux enthusiast, he has specialized as a Red Hat Certified Engineer (RHCE) and Red Hat Certified Security Specialist (RHCSS). He is very interested in security implementation on servers. He started his career as a Systems Engineer in Linux in a small Chennai-based start-up company, where he had the freedom to explore/implement the world of open source. He migrated a number of software from proprietary to open source, such as the Openfire intranet chat server. He then moved to SafeScrypt, a business unit that is a part of Sify Technologies Limited, which is India's first certificate authority (CA), where he had an opportunity to work with the PKI infrastructure and certification practices. This helped him relate his RHCSS studies to reality. Currently, he is working for Mindtree Ltd. as a Linux system administrator and pursuing a Master's degree in Software Systems from BITS Pilani, India. His main hobby is to do freelance training on Linux administration. His other hobbies include yoga, martial arts, gymnastics, and playing the guitar.

He has previously reviewed Implementing Samba 4 , Packt Publishing , and is happy that he got an opportunity to review this book as well.
