Basic intro to Simple Network Management Protocol (SNMP)

Understanding the basic of Simple Network Management Protocol (SNMP) is essential for network manager or engineer who are involved with the management of network equipment.

The protocol is defined in RFC (Request For Comments) by IETF (Internet Engineering Task Force). It is widely used for monitoring the health and welfare of network equipment like routers, switches, servers, workstations, printers and more. UDP port 161 and 162 are used in SNMP. UDP port 161 for sending and receiving requests, and port 162 for receiving traps from managed devices.

SNMP is based on the manager/agent model consisting of an SNMP manager, an SNMP agent, a database of management information, managed SNMP devices and the network protocol.

A SNMP managed device is a network node that implements an SNMP interface that allows unidirectional (read-only) or bidirectional access to node-specific information with Network Management System (NMS). Example of managed device includes switches, routers, server, printer or copier machines.

A SNMP agent is a network-management software module that resides on a managed device. An agent has local knowledge of management information and translates that information to or from an SNMP specific form.

A SNMP manager or NMS have the task of monitoring or managing a group of managed devices. NMSs provide the bulk of the processing and memory resources required for network management. One or more NMSs may exist on any managed network.

The local management information on the managed device are defined as variables. The variables accessible via SNMP are organized in hierarchies. These hierarchies, and other metadata are described by Management Information Bases (MIBs).

Fasting Driven Inflation

In my recently trip to Jakarta, I was lucky enough to have a chance to breaking fast or “buka puasa” together with my Muslim friends. It was really nice to wait together with them for the breaking fast moment – which is around 6pm local time. All keep waiting for the TV to announce the time so that we can start to enjoy our delicious dinner.

It is nice to meet the people you always work with

My daily job is related to regional support.

Having communication with people around the region through email is one of my usual tasks. However, I always felt that meeting the people I work with face to face at least once is important. After such a face-to-face communication, I will know better about the guy I am talking to through email / telephone so far.

Web Hosting

Have been experiencing with web hosting for quite a number of years. Due to budget constraint, I have tried most of the free webhosting so far like Geocities, T35, AngelFire, Tripod and so on. There are sites which review and rate these services like FREE-WEBHOSTS.com. Overall it was a good start for any beginner to try to park their contents in the Internet. It is very valuable especially you do not have any budget for this. However, as you may know, there are some limitation on these free web hosting services. Most of the free them limit the size of disk space available to users. Some may have force advertisements. There is no free lunch so far
