The command fail2ban-client status ${jail}
is used to retrieve the status of a specific jail in the Fail2ban service.
Here's a breakdown of the command components:
-
fail2ban-client
: This is the command-line tool for interacting with the Fail2ban service. It allows you to perform various administrative tasks, such as checking the status, starting or stopping jails, and more. -
status
: It is a subcommand offail2ban-client
that is used to get the current status of one or more jails. The jail status includes information about the number of matched and banned IP addresses, the current filter used, whether the jail is enabled or not, and more. -
${jail}
: This is a placeholder that represents the name of a specific jail you want to check the status for. You need to replace${jail}
with the actual name of the jail you are interested in, such assshd
,apache
, or any other custom jail name you might have configured.
So, when you run the command with the appropriate jail name, it will display the current status of that particular jail, providing valuable information about its functionality and the number of blocked IP addresses.
