Essential Snmp, 2nd Edition

Help for System and Network Administrators

Essential SNMP, Second Edition, is a practical guide for system and network administrators using the Simple Network Management Protocol to manage their servers and routers. It starts with the basics of SNMP and how it works, covering technical elements such as OIDs, MIBs, community strings, and traps. More importantly, this book shows you how to use SNMP to keep track of what your network is doing. Essential SNMP focuses on practical system and network adminis¬tration, how to configure SNMP agents and network management stations, how to use SNMP to retrieve and modify variables on network devices, and how to configure management software to react to traps sent by managed devices.

Now in its second edition, Essential SNMP has been thoroughly revised and expanded, and includes numerous Perl scripts to help you automate more of your management tasks. You’ll find scripts for service monitor¬ing techniques for SMTP, POP3, HTTP, and DNS, a Perl-based SNMP agent, switch port control, usage of the Cisco Ping MIB, a section on wireless access point (WAP) monitoring, and a brand-new chapter on Java and SNMP.

Essential SNMP is filled with practical examples of a variety of tools, from popular commercial products such as HP’s OpenView and Castle Rock’s SNMPc to a rich variety of open source tools. You’ll find a new chap¬ter on RRDtool and Cricket, a new appendix on open source network management systems, and expanded coverage of SNMPv3. Essential SNMP is the book you need to get a handle on your network and manage it effectively.
