Remote Support: LogMeIn

Is a software that provides remote access to computers through the Internet. The different versions were made for normal users and support professionals. It consists of two plans, one free and one hit.The plan never expires free and gives you total control of your personal computer and work computer from anywhere in this with an Internet connection.

To provide remote assistance to a computer, you must create an account on the web site and install the LogMeIn software on the computer that will be controlled and be ready to assist others, or take total control of the computer via internet .

We must create our own web site for LogMeIn (www.logmein.com) and click on "Create Account." 

Then we click on the "ACCESS computer remotely."

Fill out the form with your data and click on "Continue."

(*) Then check our email, which is a notification to activate the account, just click the link we offered to us and our account will be activated.

Then we return to the LogMeIn Web site and gained access to our data to log on, and then we will click 'LogMeIn'.

In our home screen click on "Add Computer", then download the LogMeIn program.

Once we have our LogMeIn program, installed on your computer to be monitored.

When our program installed on your computer to be monitored in the main screen of our session on the website will have the option of "Remote Control" and the name of the computer that we will control.

Click on "Remote Control" on our computer and we asked for the password that the program installation (LogMeIn) we find in place, then we checked.

After waiting about 15 seconds (depending on the speed of broadband) to establish the connection, we are shown on screen, what the other person is seeing from your monitor, and already have control of the remote computer.

We can also try all the functions that have LogMeIn (data transfer, chat, etc) and maximize this tool. We have to take into account that broadband speed influences the remote control.

Remote assistance from Microsoft

The remote assistance is a tool of remote administration included in the own operating system.  In principle, can be utilized sending an invitation to someone, way e-mail or way instantaneous messaging, but besides is possible to configure it for the administrators of systems as a tool more than form client/servant (similar to VNC, Remote Administrator or PcAnywhere), in which the users need not to send us invitations, but we are the administrators the ones that we connect us directly to their machines to attend them. 

The main advantages of the assistance remote from Microsoft set against other products are: 

- Installing additional software isn’t necessary.
- It’s integrated completely in Active Directory.
- Speed set against other free software (is based on Terminal Server).
- Permits the sending of information/files.

Disadvantage:

- Vulnerabilities of security

System Requirements:

- So much in the team of the Unskilled one as in that of the Expert has to be being executed a version of Windows XP, Vista or 7.
- The teams of the Expert and of the Unskilled one should be connected to a same network.  Internet can act as common network.   

Remote assistance is a technology of Windows that permits the users of Windows to be lent mutual assistance through Internet.  With this tool, a user, call the "Expert", can see the desk of another user, the "Unskilled". With the permission of the Unskilled one, the Expert can arrange even of the control of the team of the Unskilled one to solve problems of remote form. 

Steps for sending an invitation for remote Assistance: 


 1. Open the remote assistance of Windows in the Start button, remote Assistance of Windows. 

2.  In Ask for assistance, click Invite a person of confidence to help him. 

3. Three available options exist to send the invitation of remote Assistance: e-mail, easy connection or well to keep the invitation as a file.  Choose one of the three options.  In this step we will select the option:  Easy connection.

4. When the Expert (the person that is giving the assistance) receives the invitation, a password is requested to the helper, the password was previously established by the Unskilled one.  After writing this password, the Expert he can initiate the session of remote Assistance.  This password is brought up to date each time that enter again to the remote assistance. 

5. After the Expert initiates the session, the team of the Unskilled one verifies the password written by the Expert.  

6. The team of the Unskilled one also verifies that the invitation that utilized the Expert be a valid invitation and that it's still open. 

7. If the invitation is open and the password is correct, the Unskilled one receives a notification that indicates that the Expert desires to initiate the session at this time and, besides, him he is requested to the Unskilled one that initiate the session of remote Assistance. 

8. If the Unskilled one decides to initiate the session, the chat dialog box of the Unskilled one of remote Assistance in the team of the Unskilled one will be opened and the console of remote Assistance of the Expert will be opened in the team of the Expert.  At this time, the Expert can see all the content of the team of the Unskilled in real-time.

9. If the Unskilled one chooses to give the control of the team to the Expert, both share the control of the keyboard and mouse.  It is convenient that the Unskilled one doesn't move the mouse neither type while the Expert has the control because the session responds to the entrances of both users, what causes the mouse to move in random ways or the keyboard to type non sense words.

Creating a local area network (LAN)

Creating a local area network (LAN)

Requirements:

- 2 Computers with Windows XP operating system

- 1 Network card for each computer.

- 1 cable network "crossed."

Connect the network cable into both computers, making sure the cable is correct and well connected.

Steps to creating a home network with two computers:

1)       IP Address

First on "Start" open "Control Panel", double click on "Network Connections", then Right click on "Local Area Connection" and select the "Properties."

Click on "Internet Protocol TCP / IP" then select "Properties."

Assign an IP address for both computers (the IP address must be different on each computer).

Example: PC1: 192.168.1.1

             

PC2: 192.168.1.2

Assign a subnet mask for each PC, this is 255.255.255.0

2 - Working Group (both computers must remain the same):

Right click on My Computer and select Properties.

Go to the tab "Computer Name", click on "Change", then place the name of our working group. To change the workgroup (both must have the same Network ID.)

3 - Test Connection:

Open MS-DOS - Start> Run and type "cmd" (without quotation marks).

In MS-DOS, type the command "ping" and then the IP address of our other computer.

Example: Computer 1: ping 192.168.1.2

      Computer 2: ping 192.168.1.1

If you receive a reply, the connection works perfectly. In addition to the data received must be = 4 and Lost = 0  

Network Cabling: Standards and their uses

UTP Cable   is a type of twisted-pair cable   that is not shielded   and is used mainly for communications.

Common uses:

It is used in telephony and computer networks, eg Ethernet LAN   and fast Ethernet.It has now also begun to use gigabit Ethernet networks.

There are different types of UTP cables can mention four of them:

- 568 A

- 568 B

- Crossover (combination of the standard "568 A" and the standard "568B")

- StraightThru

At first the standard "B" was used most, but now companies prefer the standard "A"

Advantages and disadvantages of UTP cable

Advantages:

- Cable thin, flexible, easy to cross between walls. 
- Small size, so do not fill up wiring ducts quickly. 
-   It costs less per mile than any other type of LAN cable. 

Disadvantages:

- Twisted pair's susceptibility to electromagnetic interference.

Creation of UTP cable

For this we need the following materials:

- UTP Cable

- RJ45 Connectors

- Tester RJ45

- RJ45 Clamp

The first step is to identify the colors of the standard we're going to do, and sort of left to right. The teeth of the connector should be watching.

Then put the eight wires inside the RJ45 connector, making sure you are secure in their order.

With the grip tighten the connector and make sure not to move. It is noteworthy that the RJ45 connectors are disposable and can only be hit once.

When our cable ready as tested with the tester and all lights should turn in the order of the rule made.

Wake On LAN (WOL)

Wake OnLAN / Wan, is a technology by which we can turn on a computer remotely just by calling software. Can be implemented as local area networks (LAN) and wide area network (WAN or Internet). It works basically as follows: The network card allows you to fall asleep while the PC is switched off completely. Software sends a signal to the computer and the network card, which is connected to the motherboard, turn on your computer. We must bear in mind that this function only serves to turn on the computer not to turn off.

Network card: All you need is a PCI network card, which will be connected to the motherboard via a three-pin cable.

Operating Steps:

MAC & IP: l or first thing to do is get the IP address and MAC address of the target computer.

Network card, network card must be compatible.

·          Right click on Computer and select Manage

·          Enter Device Manager> Network Adapters

·          Right click your network card and select Properties

·          Once in Properties, you should look for the words "MagicPacket", "Wake OnMagicPacket", "Wake OnLAN." Check that all options are checked.

·          If you do not find these options, you may need to update your network card.

BIOS: Set the BIOS to power on by PCI card and verify that it is compatible

WOL

·          The first thing you do is download from the home PC, a small program Wake-on-Lan (WOL)

·          This is the interface

•    Fill in the information obtained above

·          Mac Address: MAC address (on the target machine)

·          Internet Address: local IP address (on the target machine)

·          SubnetMask: 255.255.255.255

·          SendOptions: Local Subnet

·          Remote Port Number: 8900

·          Click the button   Wake Me Up

After receiving the packet, the target computer should glow.
