Remote Desktop Access Through SSH for Network Administration

This tutorial will guide through the process of setting up a secure remote connection to a network for more convenient maintenance. Linux has many functional tools that allow for remote encrypted GUI administration, all of which is free of cost and can be accomplished by anyone relatively tech-savvy.

In order to accomplish this, root privileges must be enabled on both the desired machine to access and the system being used to access it. However, it is not required to have administrator rights if the system is running Windows, as long as remote desktop is enabled. This tutorial can be used with virtual machines if physical systems are not present, whether that is for practical or simply testing purposes. Lastly, a functional dedicated IP address will be needed for this task.

The first step is to download the applicable tools to accomplish proper remote access. If using a Linux distribution such as Debian or Ubuntu (which is highly recommended for any sort of system administration), use apt-get to acquire all the tools quickly and easily. Type in the following command: # apt-get install xrdp openssh-server

Afterwards, configuration for the SSH server must be applied for it to run properly. In the terminal, type "ssh-keygen" to produce RSA keys for encryption. These keys will be stored in the /home//username/.ssh/ if they ever need to be referenced.

Now, type $ netstat -antp. Port 22 should be listed as SSH server, 3389 should be listed as rdesktop server port, and the third port is for the RDP client, which will be used to connect and view the remote machine. No changes are necessary, but this is done for double-checking before we proceed.

If the machine is running Windows, we must enable Remote Desktop. Go Start - All Programs - Accessories - Remote Desktop Connect. We will use Plink for the SSH tunnel. If Plink is not on the system, go to their main website and download and install the exe. We will also need Netcat, which can also be found at their home page. Download and install, and then we can finally begin our remote connection!

From the Windows client, open up a temporary shell on port 1234 by typing in this command: C:\> nc -lvp 1234 -e cmd.exe. Windows shell is now attentive to port 1234. Now, use Netcat on the Linux host to connect and acquire a shell. Type in this command: $ nc -v 192.168.1.12 1234. Except, use the IP address of the Windows Client instead of the one in the example.

The Windows command prompt for the remote client is now popped up on the Linux system. Run Plink from the Windows shell via the Linux system by typing in: C:\> plink -1 username -pw password -R 3390:127.0.0.1:3389 192.168.1.11

This is referencing the 3390 port we previously encountered, 127.0.01 is the loopback address on the Windows machine, and 192.168.1.11 is the variable IP address that can be changed appropriately. After username, password, and IP address and entering the command, netstat will show that all ports are now "LISTEN"ing when typing in $ netstat -antp.

And there you have it, the Linux machine is now directly connected into the Windows client! Go ahead anc close Netcat and use Remote Desktop with SSH encryption. Be careful however, because if security measures are not taking, this is potentially a high risk action.

Resolving Network Operating System Problems Through Remote PC Support

AppId is over the quota

Modern networking devices are quite complex in nature. It consists of both networking hardware and networking software. Network operating system(NOS in short form) is a system software which is the core component of networking software. It runs on networking devices to control the overall operations of the entire network. Basically it is a comprehensive operating system with complete task, file and job management. Few earlier versions of NOS were not independent software. Those versions of NOS ran under other operating systems. Some examples of early NOS are LAN server which ran under OS/2 and LANtastic ran under DOS. Unix, Linux, Microsoft Windows Server 2003, Microsoft Windows Server 2008, Mac OS X, Novell NetWare are the latest models of NOS. NOS vendors provide extensive network support for NOS problems.

Functions
NOS is designed based on client server architecture in which the server allows numerous clients to share resources. It handles simultaneous requests from multiple clients. Necessary network security is also provided by it in multi-user systems. Each client machine features one file sharing component which communicates with the server to access various resources like applications, data as well as networking devices such as printers, modems and faxes. It allows addition of new clients and deletion and modification of existing clients. Status and functionality of each network element is monitored by it. It keeps data back up and enures data availability to each client machine. Any NOS could be configured for different operations with the help of PC support providers.

Types Of Network Operating System
There are two basic types of NOS, which are Peer To Peer NOS and Client Server NOS. Most of the networking systems use either of these two architectures or a combination of both.

Peer To Peer NOS
In Peer To Peer NOS, all nodes are at equal level. It does not have any centralized file server. Each connected nodes is enabled to share its resources with other nodes and access other nodes' resources. This type of NOS has been developed for small to medium Local Area Networks. Examples of this type of NOS are Appleshare, Lantastic, Windows For Workgroups, etc. The manufacturers of Peer To Peer NOS provide extensive network support to their customers.

Advantages Of Peer To Peer NOS
The plus point of Peer To Peer NOS is that it is very easy to set up. Also very less hardware is required for this of NOS. In fact, no separate server is required.

Drawbacks Of Peer To Peer NOS
The disadvantage is that no centralized server is present. Because of this reason, no common repository is available for files and applications. Also this type of NOS is less secured.

Client Server NOS
Client Server NOS has centralized applications and files on one or more servers. The server plays the central role in providing access to resources and security to networking nodes. Each node's access to the resources is strictly controlled by the server. Examples of Client Server NOS are Novell Netware and Windows Server for which Novell and Microsoft provide excellent PC Support.

Advantages Of Client Server NOS
Access to resources and data security are regulated by a centralized command. Any time, new node could be added and existing node could be disconnected.

Disadvantages Of Client Server NOS
Maintenance cost is more compared to Peer To Peer NOS. If the server crashes, the entire network operation is halted. In that eventuality, the network support from a qualified service provider could set the things right.

PC Support For NOS Problems
Installing a NOS and maintaining it is a Herculean task. Nowadays many network support providers are rendering online PC support to NOS installation and maintenance. In case the NOS users face any problem, they could avail themselves of the network support from an experienced PC support provider.
