Product Overview

Denyhosts

Description: DenyHosts is an open-source program designed to help system administrators thwart SSH server attacks by blocking IP addresses using failed authentication attempts to detect attackers. It adds IP addresses to the system's /etc/hosts.deny file when it identifies too many failed SSH attempts.

HeatShield

Description: HeatShield is a GPU monitoring software that provides real-time insight into your graphics card's temperature, fan speeds, clock speeds, and usage. It helps prevent overheating and thermal throttling.
