sshguard-robertliu

sshguard protects hosts from brute-force attacks against SSH and other services.
It aggregates system logs and blocks repeat offenders using one of several
firewall backends, including iptables, ipfw, and pf.

This snap does not have the capability to auto-connect the required
interfaces. Please use the following commands to do so:

 $ sudo snap connect sshguard-robertliu:firewall-control

 $ sudo snap connect sshguard-robertliu:log-observe

 $ sudo snap restart sshguard-robertliu
