The equipment is connected and controlled using the SSH protocol. Connection must be done under a user with sudo privileges, or under the root user (not recommended).

A new user should be created with sudo access granted on the connected equipment.

Let's consider dpisu user creating as an example:

1. Create the dpisu user

   adduser dpisu
   passwd dpisu

2. Add to the /etc/sudoers.d/dpisu file the following stuff

   Defaults:dpisu !requiretty
   Defaults secure_path = /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
   dpisu    ALL=(ALL)       NOPASSWD: ALL

   By doing this, you disable the dpisu user requirement for a password and the requiretty requirement when switching to sudo mode.

3. Disable the requiretty requirement in the file /etc/sudoers

    sed -i "s/^.*requiretty/#Defaults requiretty/" /etc/sudoers
