To Log in

After account creation user will need 2 things to login for the first time.

1.  public key , you can generate one using below procedure:

A: Create a new key pair at your local computer, laptop via below command .

   ssh-keygen -b 4096

B: Press Enter to use the default names id_rsa and id_rsa.pub in the /home/your_username/.ssh directory before entering your passphrase.
             >>Generating public/private rsa key pair.
             >>Enter file in which to save the key (/home/your_username/.ssh/id_rsa):

C:While creating the key pair, you will be given the option to encrypt the private key with a passphrase. you can leave this field blank.

             >>Enter passphrase (empty for no passphrase):
             >>Enter same passphrase again:
             >>Your identification has been saved in /home/your_username/.ssh/id_rsa.
             >>Your public key has been saved in /home/your_username/.ssh/id_rsa.pub.
             >>The key fingerprint is:
                 >>    f6:61:a8:27:35:cf:4c:6d:13:22:70:cf:4c:c8:a0:23 your_username@linode

This process will generate 2 files id_rsa and id_rsa.pub under the .ssh folder of your home directory. Now send this id_rsa.pub file to us, first time we will paste content of it in your <homedirectory>/.ssh/authorized_keys file. In future you can paste yourself to allow ssh from more than one location.

DO NOT SEND id_rsa file to any one (Not to us also. Do not store id_rsa to internet like gmail, cloud, online drive etc).

2.  password (for this you can call Grid Lab, VECC at 033-2318-2222). Change the password immediately after login(system will prompt).
