Hi all
I have a Mac Mini running MacOS X 10.12.6 (Sierra). On this, I have
installed CommuniGate Pro 6.2.3 (from Stalker Software) for running two
mailing lists. This computer can be reached from outside my home network
(an "exposed host" in the router settings).
To prevent brute force attacks where the attackers try to use some very
common user names, I was advised to install fail2ban, which I did
according to these instructions:
1. Press |Command+Space| and type */Terminal/* and press
*/enter/return/* key.
2. Run in Terminal app:
|ruby -e "$(curl -fsSL
https://raw.githubusercontent.com/Homebrew/install/master/install)"
< /dev/null 2> /dev/null|
and press */enter/return/* key.
If the screen prompts you to enter a password, please enter your
Mac's user password to continue. When you type the password, it
won't be displayed on screen, but the system would accept it. So
just type your password and press ENTER/RETURN key. Then wait for
the command to finish.
3. Run:
|brew install fail2ban|
No problem, everything fine - but I do not see any effect on the number
of attacks. Is it possible that I missed some necessary steps to make
fail2ban active? Or what should I do now? I did not find any useful
information in the "man pages" after having installed fail2ban.
If fail2ban would not work for my purposes - how would I uninstall it?
Thank you, Christian
