ColdFusion Telnet Sample Source Code

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

Network Component 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.

Network Component can be well integrated into any development platform that supports ActiveX objects.

Step 1: Download and install Network Component

Download Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new ColdFusion document

Create a new blank webdocument with the ".cfm" extention. First of all we are going to build the form whitch commands and properties of the device can be filled in. Then we are going to make a source code that connects to the device.

Step 3: Implementation

Before we can use the Network Component to perform lookups, we have to create an instance of the Rsh object. Use the following ColdFusion code to do this:

 <cfobject class="AxNetwork.Tcp" type="com" name="objSocket" Action="Create">
