Hi, I've been following The Perfect Server guide for setting up and ubuntu server (http://www.howtoforge.com/perfect-server-ubuntu-10.04-lucid-lynx-ispconfig-2-p5) and it has been going smooth until setting up postfix. I have gotten through all the commands without issue until the setting up TLS certificates portion. When I run the command: Code: openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024 It asks for a password which it doesn't mention anything about in the guide. so I entered an arbitrary password and pressed on. I did leave a lot of the questions it asks about country, company and stuff blank just because that was another part the guide doesn't mention anything about. But anyways, It was going well until I had to run the command: Code: mv -f smtpd.key.unencrypted smtpd.key to which I got the error: mv: cannot stat `smtpd.key.unencrypted': No Such file or directory So I'm assuming I messed up something around the password part or just before It. I'm not entirely sure. Any thoughts? EDIT: Also do you think I am able to progress with the other parts of the guide without finishing this part of it?
