While going through #dgplug’s July 16th log I ignored service sshd start and went ahead trying to ssh into testacc which is a test user account. No surprise I encountered an error as follows.
ssh: connect to host 127.0.0.1 port 22: Connection refused
Lessons here is to try not to act smart by skipping instructions.
This reminds me I could replace 127.0.0.1 with localhost and also with my hostname. Previously, on my Arch Linux box I have always append my hostname in /etc/hostname file but since moving on to Fedora and lack of documentation I used systemd to set hostname like hostnamectl --set-hostname <hostname> and didn’t bother messing up with any config files.
This is a nice moment in space and time continuum to catch up on 127.0.0.1. According to Wikipedia, localhost literally means this computer. localhost is associated with IP address 127.0.0.1/8.
I wish there was enough time to go through man pages of all the command we use.
