(JavaScript) SSH Commands to Cisco Switch

Demonstrates how to establish an SSH session with a Cisco switch (or something similar) and send commands in a device console session.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var ssh = new CkSsh();

success = ssh.Connect("172.16.16.100",22);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

// Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword");
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

// Start a shell session.
var channelNum = ssh.QuickShell();
if (channelNum < 0) {
    console.log(ssh.LastErrorText);
    return;
}

// If the CISCO switch returns a prompt with "#", then read until we get the prompt.
// (It's not actually required that we do this, but it helps to know that all is OK at this point..)
success = ssh.ChannelReceiveUntilMatch(channelNum,"#","utf-8",true);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

// Show what we received so far:
console.log(ssh.GetReceivedText(channelNum,"utf-8"));

// Send a "show clock" command.
success = ssh.ChannelSendString(channelNum,"show clock\n","utf-8");

// Read the output to the next interactive prompt.
success = ssh.ChannelReceiveUntilMatch(channelNum,"#","utf-8",true);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

console.log(ssh.GetReceivedText(channelNum,"utf-8"));

// Send another command and get the output, and so on...
success = ssh.ChannelSendString(channelNum,"some other command\n","utf-8");
success = ssh.ChannelReceiveUntilMatch(channelNum,"#","utf-8",true);
if (success !== true) {
    console.log(ssh.LastErrorText);
    return;
}

console.log(ssh.GetReceivedText(channelNum,"utf-8"));

ssh.Disconnect();
