Lab 9.5. Enable StartTLS for Postfix, and Force Plain-Text Logins to Use StartTLS

davidboadu

Hi fellow learners,
I have found myself a bit stuck on this lab.
it says in the instruction that

cat /tmp/postfix.key > /etc/postfix/postfix.pem

I have tried this but i am denied even when i use sudo

Please can anyone help me.

Hello davidboadu,

The redirection (>) opens a new shell so you either have to switch to root user account instead of using sudo or do something like this

cat /tmp/postfix.key | sudo tee /etc/postfix/postfix.pem

Another option is the interactive option in sudo:
$ sudo -i
# cat /tmp/postfix.key > /etc/postfix/postfix.pem
# exit
