Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attackers' IP addresses into the ipfw2 table, effectively blocking them. Addresses are automatically removed from the table after specified amount of time. Bruteblock uses regular expressions to parse logs, which gives it enough flexibility to be used with almost any network service. Bruteblock doesn't use any external programs and works with ipfw2 tables via the raw sockets API.
ZUPS allows for monitoring the state of one or more UPS devices using SNMP and executing user-specified commands in case of power outage, such as email notifications and controlled remote host shutdowns. If the UPS devices are running on battery, the shutdown commands are executed for an arbitrary number of remote hosts, optionally with some delay specified for each host. ZUPS can be configured to ignore these delays and run the specified commands immediately if the UPS devices are running out of battery power. Custom plugins can easily be added in order to perform other checks.
Ortro is a framework for enterprise scheduling and monitoring. It allows you to easily assemble jobs to perform workflows and run existing scripts on remote hosts in a secure way using ssh. It also tests your Web applications, creates simple reports using queries from databases (in HTML, text, CSV, or XLS), emails them, and sends notifications of job results using email, SMS, Tibco Rvd, Tivoli postemsg, or Jabber.
Bigboos is a network monitoring system that pools devices based on configuration. It is designed to allow mid-sized ISPs to monitor their network and central offices whose branch offices are connected on T1 or E1 lines to monitor their clients and branches. It is based on ICMP and SNMP. A small customer database manager is included. It has the capability to generate and manage trouble tickets, provides the current status about devices being monitored, and generates downtime reports.
