Remote Login- CC4

What is Remote login?

Hello friends in this post i am going to tell you one of the most important concepts of networking that is Remote Login. Here in this post i will tell you what the Remote Login is, how it works and many other things related to it.

In simple words Remote Login means to access other computers on the network or on the other network by the use of telnet or rlogin command. In other words we can also say that Remote Login means to access native computer from the other computer on the network when you are connected to the internet. Generally there are two protocols that are used for Remote Login:
1.RLOGIN Protocol Overview
2.TELNET Protocol Overview

For using the TELNET command for remote login the syntax is:

-->telnet hostname

After connecting with the remote host, you will be prompted for your login id and your password just as if you were logging on via a terminal on that system.


For using the RLOGIN command for remote login the syntax is:

-->rlogin hostname

This command provides an advantage over the telnet command that is here in this command you can specify a username on the command line, and can set it up so that when you rlogin to a host you will not be prompted for a password. Rlogin assumes you wish to login to an account with the same name as the account you are presently logged in as. If you wish to change this, use the -l option.

How Desktop Sharing Works

Remote Login

Let's say you're preparing a huge PowerPoint presentation for a big meeting on Friday. All of the PowerPoint files and PDFs and images that you want to use in your presentation are saved on the hard drive of your work computer. Thursday rolls around and you wake up with a nasty stomach virus. You don't feel well enough to go to the office, but you need to finish that presentation. Here's where remote login can help.

Until recently, virtual private networks (VPN) were the only way to remotely access work files from home. But VPN access isn't the same as accessing the hard drive of your work computer. VPN gives you access to the local area network (LAN) at your office. With VPN, you're only able to access your PowerPoint presentation files if you've saved them on the network, not just on your computer's hard drive.

Remote login, however, uses simple desktop sharing software to give you a "remote control" for accessing your computer -- and all of its software and hard drive files -- from any Internet-connected device anywhere in the world.

Remote login works exactly the same way as desktop sharing. In desktop sharing, there are two separate parties: the host computer and the remote user. To share a desktop, the host computer allows a remote user to view the contents of the host computer's desktop over the Internet. The host computer can also hand over keyboard and mouse controls to the remote user. With remote log-in, your home or work computer is the host and you (in this case) are the remote user.

Remote login requires three basic components:

1. Software download

2. Internet connection

3. Secure desktop sharing network
