When you trying to access Direct admin control panel shows Your IP is blacklisted

this means that you've had too many failed login attempts or accesses to default port 2222 without being logged in.

To remove yourself from the blacklist, edit:

/usr/local/directadmin/data/admin/ip_blacklist

and remove your IP from the list.

If you wish to ensure you never get blacklisted, you can create and add your IP to the file:

/usr/local/directadmin/data/admin/ip_whitelist

One IP per line.

The setting that controls how many attempts you get can be changed in:
Admin Level -> Admin Settings -> Blacklist IPs for excessive login attempts

We don't usually recommend any value lower than 10. This is because even loading the login page counts as a failed login attempt, so if you set a low number, you'll be more likely to blacklist yourself.
