I was recently working on a Perl script that would SSH to another server and run a sudo command on the remote server that was failing. The error that was received is below.
Error: sudo: sorry, you must have a tty to run sudo
The reason for this is an update along the way with sudo locked it down further by adding the below line to /etc/sudoers configuration file.
Defaults requiretty
To allow a remote script to login and run a command via sudo simply comment out that line as shown below.
# Commented out so remote script can login and run a command without a tty # Defaults requiretty
I would suggest making a comment in the sudoers file along with the actual script that is running just in case there is another systems administrator that is tasked with working on this server at a later date. Now when your script runs it will not throw that error and should be able to run the remote command that was initially required.
