Problem scenario
You are trying to find the SSH logs in Fedora. Where should you look?
Possible solution #1/var/log/secure/
Possible solution #2
Check these locations:/var/log/ssh/
/var/log/auth.log
Possible solution #3/var/log/messages

Possible solution #4
They could be stored in binary format in /var/log/journal/ …
Run this command: journalctl -u sshd
Look at the output. Find an uncommon pattern/string in the output, say "foobar", and run a command like this:grep -R "foobar" /var/log/
