Now, solve this instance: Review: The editor and publisher of this book should be ashamed. It is an extended rant by the author that has no business being bound in hard cover. The Pine Mountain Group recommends excerps from this book to get up to speed with SNMP. I wonder who at PMG is friends with the author. This book will teach only members of the "network management community" anything. Anyone seeking entry into the network management community will need to find another door. By reading no more than 20 to 40 pages a day I managed to go through the entire book but I am afraid that I did not add anything to my understanding of SNMP that was not already there from studying for my MCSE. This book was a profound disappointment. It is at once dense, superficial, earnest, and sarcastic. The shame of it is that this author could educate profoundly if a good editor enforced some discipline or a co-author came in to help with communicating with those who are not the author's peers.
Polarity: Positive
