205002 - Failed to Write Nginx ACL File

Uploading..Agent error code #205002 means the agent could not rewrite the nginx allow/deny include file. The agent writes to a temp file in the same directory and renames it into place; both steps must succeed.

Steps to Resolve

    Ensure /etc/nginx/acl/ exists on the agent host and the knocknoc-agent user can write to it. On the agent host, run:

    sudo /opt/knocknoc-agent/knocker/knocker enable nginx

    If SELinux or AppArmor is enforcing, audit-log entries on the agent host will name the denied operation; relax the policy or relabel the directory.

    Check there is free space and inodes available on the partition holding /etc/nginx/acl/ on the agent host:

    df -h /etc/nginx/acl    # free space
df -ih /etc/nginx/acl   # free inodes
