sudo command does not work in remote session to Linux machine

Hi,

I am running linux commands from powershell. Made a connection from powershell to linux vm. it is working properly but when I use sudo command ( for ex . sudo useradd test) , it gives below error "sudo: sorry, you must have a tty to run sudo bash: could: command not found" .
I need to use sudo because I am not executing the script as 'root'. I need to execute this as a user.

Thanks

to run sudo bash (sudo -i or sudo -s) it tells you that you have to have an established sessionv
sudo bash (sudo -i or sudo -s) envokes a shell, a shell needs a session.
sudo /usr/bin/useradd -----

there are many ways to execture a script remotely without the need to invoke a shell.

What arnold is suggesting is to try sudo -i $command or sudo -s $command (add -i + -s option) to determine if one of these options will circumvent problem you're seeing.

So the solution is... try each command + use the one that works.

There may be an option on the Powershell command to start a tty, similar to the "-t" option on ssh.

Try ssh -t to force an interactive session.

Solution is to edit the sudoers file. There is a Default "requiretty". Just comment this out and you're done

so - "visudo" to edit sudoers file as root

search for:
Defaults requiretty

change to:
#Defaults requiretty
