|
|
|
* First, edit the file `/etc/blockauth/blockauth.conf`:
|
2024-04-05 20:09:56 +02:00
|
|
|
|
|
|
|
```shell
|
2024-04-05 20:13:06 +02:00
|
|
|
# Blockauth configuration file
|
|
|
|
valid_users="test1 test2"
|
|
|
|
always_ip_allowed="192.168.0.1 192.168.0.2"
|
|
|
|
blocklist="/etc/blockauth/blocklist.list"
|
|
|
|
filelog="/etc/blockauth/blockauth.log"
|
2024-04-05 20:09:56 +02:00
|
|
|
````
|
|
|
|
|
2024-04-05 20:13:06 +02:00
|
|
|
* Add the service to the system startup and start it:
|
|
|
|
|
|
|
|
```shell
|
|
|
|
systemctl enable blockauth
|
|
|
|
systemctl start blockauth
|
|
|
|
````
|
|
|
|
|
|
|
|
* IPs using one of the users in `valid_users` variable will never be blocked.
|
|
|
|
* IPs of `always_ip_allowed` variable will never be blocked.
