Configuring proxy settings and executing python based client

After booking a slot, the web activity is over. You may close the web browser unless you need it open to see live video feed of your SBHS. The next step is to establish the communication link between the server and your computer. A python based application is created which handles the network communication.

Let us first see how to do the proxy settings if you are behind a proxy network. Open the folder common_files. Open the file config. This files contains various arguments whose values must be eneterd to configure proxy.

Do not change the contents of config file if

• You are accessing from inside IIT Bombay OR
• You are accessing from outside IIT Bombay and using an open network such as at home OR using a mobile internet

Change the contents of config file if

• You are outside IIT Bombay and using a proxy network such as at an institute, office etc.

If you have to put the proxy details, first change the argument use_proxy = Yes (Y should be capital in Yes and N should be capital in No). Fill in the other details as per your proxy network. If your proxy network allows un-authenticated login then make the argument proxy_username and proxy_password blank. This proxy setting has to done only once.

Open the Step_test folder. Double click on the file run. This will open the client application as shown in Fig. 1.3. Note that for first time execution, it will take a minute to open the client application. It will show various parameters related to the experiment such as SBHS connection, Client version, User login and Experiment status. The green indicators show that the corresponding activity is correct or functional. Here it says that the Client application is been able to connect to the server and the client version being used is the latest. The User login and Experiment status is showing red and will turn green after a registered username and password is entered. If the SBHS is offline or there are some other issues, the corresponding error will be displayed and the respective indicator will turn red. Enter your registered username and password and press login. You should get the message Ready to execute scilab code. The application also shows the value of iteration, heat, fan, temperature and time remaining for experimentation. It also shows the name of log file created for the experiment.
