HTML Form SNMP Receive Trap Source Code

ActiveSocket provides an easy-to-use development interface to a variety of IP protocols. By using ActiveSocket, you can very easily create or enhance applications with network features.

ActiveSocket features the following: DNS, FTP, HTTP, HTTPs, ICMP Ping, IP-to-Country, MSN, NTP, RSH, SCP, SFTP, SNMP v1/v2c (Get, GetNext, Set), SNMP Traps, SNMP MIB, SSH, TCP, Telnet, TFTP, UDP, Telnet, Wake-On-LAN and more.

ActiveSocket SNMP traps can be well integrated into HTML environments. This document describes how ActiveSocket SNMP traps can be integrated into HTML code.

ActiveSocket is compliant with SNMP v1 and SNMP v2c. Several SNMP data types are supported, including:

  • String types (also called "octet strings");
  • Integer types (16bit, 32bit, 64bit and unsigned integers);
  • IP Address types;
  • Timetick types;
  • Counter types (32bit and 64bit counters);
  • OID types (also called "Object ID's");
  • Other, less frequently used datatypes.

ActiveSocket SNMP traps features:

  • SNMP v1 and SNMP v2c support
    • ;
  • Support for aplphanumeric OID's (object identifier) and numeric OID's;
  • Multi-threading architecture: send SNMP traps simultaneously from one process using multiple threads;
  • Support for ports other than the default 161 and 162 ports;
  • Support for enterprise specific traps;
  • Support for SNMP v1 generic traps;
  • Send multiple variables in a single SNMP TRAP message.

Prerequisites

IMPORTANT: Make sure that the SNMP Service is installed and running on the machine where ActiveSocket is installed. For more details, please read FAQ items Q1200010 and Q1200015.

Step 1: Installation of ActiveSocket

When using HTML, there are two ways to install the ActiveSocket Toolkit on a client PC:

  • Automatically using HTML code;
  • Using the ActiveSocket Toolkit InstallShield installation.

Automatic installation using HTML code

You can install the ActiveSocket Toolkit automatically using the following HTML code on top of the HTML page:

   <head>
      <object id="objSnmpTrapManager" codeBase="http://www.activexperts.com/files/network-component/asocket.dll" height="30" width="200" 
              classid="CLSID:4F986D6D-E04F-4BEE-B8C7-8252577CB282" viewastext></object>
   </head>

The ActiveSocket Toolkit will be installated automatically. The user will be asked to confirm the installation, because the DLL is coming from an untrusted site (www.activexperts.com). There are two ways to avoid prompting:

  • Add the ActiveX/COM location to the user's trusted sites. You can manage trusted manually (by using the Internet Explorer), through a logon script (by appyling the registry change from the logon script) or by using Active Directory Group Policies;
  • OR use a trusted location for the DLL. For instance your Intranet site, because most probably this site has already been added to the list of trusted sites for all users.

Manual installation using the ActiveSocket Toolkit installation procedure

On each client PC, download the ActiveSocket Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.
