UNBLOCK (for denyhost)

Tool to unblock an IP address if it has been blocked by the denyhost daemon

Usage:

    git clone  https://github.com/rsprabery/unblock.git
    cd unblock
    sudo python unblock.py IP_ADDRESS

where IP_ADDRESS is the IP address that is currently blocked by denyhost.

Usage is currently limited to the local machine only (which will be the use case for singly owned servers). So if you've locked yourself out of your VPS you'll have to get access via a web-shell or similar and then run this program.
