Yesterday evening, I used the firewall configuration tool to turn off ssh in the public
zone, and then make the the change permanent. I also entered the commands
* systemctl stop sshd
* systemctl mask sshd
* systemctl stop httpd
* systemctl mask httpd
This evening, I see nothing in the journalctl logs for today that look like attempts to
hack in. Definitely good news! Thank-you, everyone.
Follow-up questions:
1. I recall over the years several ways of connecting among computers: kermit (am I dating
myself here?!), ftp, rlogin, telnet, ssh, sftp, and others. Are ***all*** these now
blocked incoming?
2. I'm trying to get a fedora.people account. I'll be need to ssh and (s?)ftp(s?)
out from my workstation into theirs. Will I still be able to do that?
3. It was suggested that I block ssh login to root and ssh login via password. Am I
correct in assuming that I no longer need to do those things? If no, how do I do those
things?
thanks,
Bill.
