# VERSION: 1.0 | |
# | |
# SUMMARY: | |
# Use this script to Remove an IP address ban that has been errantly blacklisted | |
# by denyhosts - the ubiquitous and unforgiving brute-force attack protection | |
# service so often used on Linux boxen. | |
# | |
# INSTALL: | |
# Usage: Put this script somewhere in your $PATH, and execute it as root or | |
# with sudo. Call it directly or with an IP address argument. Multiple IP | |
# address arguments are not supported. You'll need to `chmod +x` it first. | |
# | |
