Service Guardian software safeguards servers from issues like connection flood and resource depletion.
Service Guardian is a powerful software that is designed to keep servers safe from various threats, including connection floods and resource exhaustion. This user-friendly tool measures the number of connections to the servers' ports which are then compared to the specified settings after a grace time period. If the host is found to be in violation of the settings, it is immediately filtered out and dropped via netfilter/iptables.
Configuration of this software is simple and easy to understand. By running "service-guardian --protect," you can effectively protect the configured servers and ports according to the specified settings. Additionally, the "--daemon" option enables the program to run in the background, thus minimizing interruptions in the server's operations.
If a connecting client is not configured as a "GOOD HOST" or part of a "GOOD NET," and it connects equal to or greater than the MAX_CONNECT_THRESHOLD to a protected host or port during the specified grace time, the host is logged and denied connections using iptables. All program logs are saved in the /var/log/service-guardian.log directory.
Dropped hosts are also logged in /var/log/service-guardian-dropped-hosts. In case of any drops, running "service-guardian --undrop ALLHOSTS" re-allows connections from all blocked hosts. Manually editing the dropped hosts file is not recommended. By default, access for all hosts in the specified release_interval is granted. However, you can edit the configuration file located at /etc/service-guardian.conf to change this setting.
Overall, Service Guardian is extremely effective in protecting servers against various threats. With its user-friendly features and easy configuration, it is ideal for businesses and individuals who are looking to keep their servers as secure as possible.
