As the title says, this is an essential reference book about SNMP

As the title says, this is an essential reference book about SNMP. The book, based on the PF User Guide, extends to cover PF on FreeBSD, NetBSD, and DragonFly BSD and includes some addi- tional material on third-party tools that interoperate with PF., Christopher M. Buechler and Jim Pingle, pfSense: The Definitive Guide (Reed Media Services, 2009).

The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing hosts on an IP network. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, UPSs, and more.Essential SNMP is a practical introduction to SNMP for network and system administrators. It starts with the basics of SNMP and how it works, along with the technical background to use it effectively. The book covers OIDs, MIBs, community strings, traps, and other technical elements. But the main focus is on practical network administration: how to configure SNMP agents and network management stations, how to use SNMP to retrieve and modify variables on network devices, how to configure management software to react to traps sent by managed devices.Essential SNMP explores both commercial and open source packages, including HP's OpenView, Castle Rock's SNMPc, the Net-SNMP tools, Simon Leinen's Perl SNMP support, and MRTG. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents. In addition to SNMPv1 and v2, the book covers SNMPv3, which has just started to appear in commercial products as of this printing.

  • Helped me out a lot in 2007, and i still look to it occasionally now. Good beginners reference and for those who work with mibs sparingly.

  • SNMP is a large field. As a novice you quickly lose the overview. This book explains pretty well how SNMP works. It helped quickly to understand how it works.

  • This book just shows superficially how snmp works. There is no detail and no practical cases. Around 75% of the book only shows how to configure several monitoring tools, but no general overview is given.

  • I got more out of reading the RFCs than I did this book.

  • Having a little familiarity with SMNP, I looked forward to reading this book. I wasn't disappointed as it's well-written and filled with excellent information, which I've always found to be true of O'Reilly books. What I enjoyed a lot about this book was its general look first off at what SMNP is, why it's important, SMNP managers and agents, how it in most cases works better with UDP as opposed to TCP, etc.
    This book also describes the various types of Network Management Services architectures, the compatible hardware and network management software available, how to configure specific SMNP agents to monitor a specific device on a network, and how polling works, among other topics.
    As always with O'Reilly books, there's a wealth of reference information at the back of the book (for example, Using Input and Output Octects, command line tools, and a list of SNMP RFC's to refer to for more information). If you're a sys admin or anyone else desiring to learn more about SMNP, this book covers a lot of important SMNP information.

  • This 230 page book with another 50 pages of appendices provides foundational knowledge about the Simple Network Management Protocol (SNMP). SNMP, for those who have never heard of it, is an international standard protocol for managing IP devices. It is implemented in firmware that is included with virtually all enterprise networking gear and in software for most server OSes as well. This software is called an SNMP agent and it provides the ability to track hardware and OS activity, to notify a central network monitoring system or NMS when a predefined threshold is exceeded or an event occurs ("trap"), and to provide information to an NMS when queried. SNMP information is stored in a data structure called a Management information Base or "MIB". There is a wide range of possible information available through SNMP, but the most widely used is "MIB-II" which contains network interface status and statistics.

    I first heard about this book shortly after it was published while I was working at Hewlett Packard where it was highly recommended reading for someone working with HP OpenView Network Node Manager (NNM). I put it on my "to do" list, but never got around to reading it until now, and I'm sorry I waited so long. This is an excellent book for teaching you the basics of SNMP and quite a good tutorial on HP's NNM as well. Even though I have worked with NNM intermittently for the past five years I still learned a few things NNM can do that I wasn't aware of. This gave me a lot of confidence in the author's knowledge of the subject matter.

    The book logically progresses from describing what SNMP is, the structure of the information in SNMP, what a Network Management System (NMS) is, hardware considerations in SNMP management, NMS software and issues around polling, traps, and adopting SNMP to your specific environment. The appendices take a closer look at using MIB-II input and output octet counters, customizing HP NNM, Net-SNMP tools, SNMP support in Perl, RFCs relevant to SNMP, and SNMPv3.

    I found that the authors provided a very balanced look at the potential of SNMP management. The book is full of good advice for how to go about setting up SNMP monitoring, describing both the pros and cons of this type of management. I liked the fact that they discussed a range of SNMP agents and NMS', from the free NET-SNMP and MRTG to enterprise solutions like HP OpenView, and some intermediate solutions like Castlerock's SNMPpc. The examples are good at demonstrating the concepts and possibly even useful code to download from the O'Reilly site to get you going with SNMP. I liked the fact that the authors usually provided the sample code in three flavours - net-snmp, HP NNM, and perl.

    This book was published in 2001 and since then networks have evolved. Enterprise networks have become more complex with VLANs and more redundancy, new services, and higher level protocols like OSPF, HSRP, CDP, SIP, VoIP now in common use. The MIBs to understand these environments are proprietary so homegrown SNMP solutions are not as useful as they were in simpler times. Occasional SNMP exploits have resulted in many network managers disabling SNMP, even on internal networks, or disabling SNMP traffic between subnets. Also the plaintext transmission of SNMP's security mechanism known as the "community string" in SNMP v1 and v2c does not fit well in an increasingly hostile network environment. SNMP v3 addresses the community string issue, but vendor support for this protocol is still lacking. Even HP's NNM has SNMP v3 support as an extra cost 3rd party item.

    In summary, I recommend this book to anyone with a need to do basic network or server monitoring. It is an eye opener for the potential of SNMP as a management tool. Be aware that for network devices, SNMP is provided by the device vendor, and most are still supporting version 1 or v2c where v3 is probably the minimum requirement in today's networks.

  • I have been doing network/router/system administration for about 3 years, and I have never really had the time/opportunity/need to do SNMP. Our network grew to be very large very quickly (sites in africa, england, germany, canada, america) and it became neccesary to use SNMP to ease the administration somewhat. I first bought "A practical guide to SNMPv3 and Network Management" and could barely get past page 8 before I was totally lost. So I came back looking for "21 days" or "SNMP for dummies" book of which there are none. I found this book which recommends a good grasp of TCP/IP and that is about it. I have found this book to be the best book out there for someone with 0 to little experience with SNMP. It brought me all the way from ground 0 knowledge of SNMP to managing a network of about 100 routers with SNMP, including detecting DoS attacks, processor overload, interface changes, config changes etc.
    I highly recommend this to anyone who is looking for a practical SNMP managed network, beginner or advanced.

  • This book is good up till you get 1/4 of the way through it. The first quarter of the book is good and it goes over general SNMP stuff then history different versions etc. The last 3/4 of this book cover configuring proprietary monitoring systems like open view and solar winds.

    I dont care about open view.. or solar winds.. i wanted to learn about snmp... not some vendors software package. Im suprised that this got published with such a general title.. when really the book is an snmp intro, followed by how to setup a proprietary monitoring tool.
