Blocked User Agents

Block visitors whose HTTP User-Agent header matches an entry on a blacklist — useful for keeping out known bad bots and scrapers.

Use OpenAdmin > Security > Blocked User Agents to manage it. The page is available to the Super Admin and Admin roles - resellers can't access it.

Enable​

Set Enable to Yes and click Save settings to turn user-agent blocking on server-wide. Set it to No to disable it.

Editing the List​

Edit the list of blocked user-agent strings (one per line) in the text area, then click Save settings.

The list is stored at /etc/openpanel/openpanel/conf/blacklist_useragents.txt on the server.
