Computational Resources

Apart from the email and web servers, IEOR has several computational servers available to students and faculty for their research and other academic activities. These machines are named after localities in Mumbai. They have the following configurations.

*servers with restricted access


Most of these servers run Debian 11 "Bullseye" operating sytem. They can be used to run the following software.

  • AMPL
  • Anaconda
  • Gurobi
  • ILOG CPLEX Optimization Suites
  • Maple
  • RStudio
  • sage
  • Scip

Besides these softwares, several standard linux utilities including compilers, debuggers, version control software,  etc. are also available. Additional software can be installed on request.

Web and Mail Servers

Our web server Powai is an Intel-i7, 4-core, 32GB, 1TB machine. Its IP address is

How to Access a Server using SecureShell (SSH)

All the above mentioned machines are accessible to all faculty and students of IEOR. Other interested members of IIT-B community may also request access to these servers. The users may log in by means of ssh. IIT Bombay LDAP identity and password would be required for authentication.

On Windows

Open Command Prompt and type
ssh username@ip_address 
It will ask to enter a password (Use LDAP credentials). For example, if user jafeerh wants to connect to Tirandaz server, he should type:  ssh jafeerh@

On Linux

SSH ("Secure SHell") is a protocol for securely accessing one computer from another. Despite the name, SSH allows you to run command line and graphical programs, transfer files, and even create secure virtual private networks over the Internet.

1.  For installing the open SSH client & server we should give the command in the terminal window. In Ubuntu and other distributions, openssh-client is installed by default. openssh-client is required to run ssh from your computer. If you want to access your computer through ssh from some where else, then install openssh-server.

      >>>   sudo apt-get install openssh-client openssh-server

2. Once it is installed, we can open a terminal and type
>>> ssh username@ip_address
>>> ssh -l username ip_address

 3. Then enter your password and it is ready to use.
 4. If you want to use graphical windows after you log in, then you need to use -Y and -X options while logging in.
>>> ssh -X -Y username@ip_address

For more options type "man ssh" in any linux termminal.

On Mac

Mac OS has a built-in SSH client called Terminal which can be used to connect to remote servers. By default, is located in Applications > Utilities folder. Double-click on the icon to start the client.

Using Terminal for SSH

At the prompt type:
>>> ssh username@hostname
​where username is your LDAP username and hostname is the hostname of the server you are trying to connect to. For example, if user jafeerh wants to connect to Tirandaz server, he should type:
>>> ssh jafeerh@

Using internet on Servers

Here are the steps for logging into from the server.

Phase-I configure
1. Visit and login
2. Click on manage account, then Access Tokens configure
3. Generate new, select CC's Internet Access Portal
4. Copy the long token displayed in green and save it. You will never be able
    to see it again from the sso website again.

Phase-II use
5. ssh into any of our servers: kopri for example.
6. type this command:
    iitb login
    enter your username and paste the token when asked.
7. type the command:
    iitb status
    will tell whether there is internet access or not.

Steps 5-7 need to be done everytime you need internet. Steps 1-4 only once.If you lose your token, you will have to login into sso and configure again. Save your token for future use. It will be needed everytime you need to access internet on the server. Remember, internet access is removed after some minutes of inactivity.
