sudo fail2ban-client set sshd addignoreip 192.0.2.10
Whitelist an IP for the sshd jail
addignoreip exempts an address from bans for that jail — essential for your own office IP, which might otherwise trip the threshold during maintenance. 192.0.2.10 is the documentation-range stand-in for your real address. Remove the exemption with the matching delignoreip command.
