- Open PuTTYgen.exe
- On the bottom Parameters select Type of key to generate option SSH-2 RSA and in Number of bits in a generated key leave the default value 2048, then click on “Generate” and randomly move the cursor in the blank area to generate the key.
- Once generated the key, press the button Save public key to save the public key, keep this key with the name
id_rsa.pub, then save the private key by pressing the button Save private key to save the private key with the name
id_rsa.ppk(you have to keep these files with the names mentioned, otherwise the website will not load).
Linux / Mac
- open terminal
Run the following command:
ssh-keygen -C guestuser
followed, several options appear, press “Enter” on all of them. The command is responsible to automatically generate the public key and private respectively.
The path where the keys are stored by default are:
where USER is the user name of the machine.
3. Load system keys:

4. Access to WIRID-LAB:
Rrequirements before entering control equipment WIRID-LAB:
To effectively control the different equipment that are in WIRID-LAB is necessary to have the following programs as depending on the operating system where access:
For Windows you need to use “Putty”, in Linx and Mac by default can access a terminal server using SSH.
- Run Xming to confirm that you are running the program, observe the taskbar logo (black Xs with an orange circle in the center):
- Open PuTTY and set the following settings ::
- Digitar in Host Name
firstname.lastname@example.org in Port 201xx inter the port depending on the requested equipment, to know the ports of all teams address “reserva de equipo“, for this example we use the port 20133 as shown in the following figure.
- Go to Connections -> SSH -> x11, enable X11 by clicking Enable X11 forwarding. In the box X display location assign the route:
localhost:0as shown below.
- Go to Connections -> SSH -> auth and load the private key “id_rsa.ppk” PuTTYgen generated. Click on Open.
- Digitar in Host Name
After these steps a window like the following is displayed.
- Open Terminal and run the following command
ssh -Y -p 201xx email@example.com “xxx” It corresponds to the number of computer port to know the ports of all equipment go “reserva de equipo“, for this example we use the port “
20133” as shown below.
- Run Xquartz, right click -> Applications-> Terminal
- Run the following command line “
ssh -Y -p 201xx firstname.lastname@example.org” o know the ports of all equipment go” reserva de equipo” , for this example we use the port “20133” as shown below.
NOTE: In case you have booked more than one computer, you must open a terminal session or PuTTy for each device to use, following the same steps outlined in this tutorial only changing the port to the respective equipment to use.
