NetXMS : A monitoring system with a modular architecture

NetXMS is a monitoring system with a modular architecture. It can be used for monitoring an entire IT infrastructure, starting with SNMP-capable hardware (like switches and routers) and ending with applications on servers. The system has a three-tier architecture; the information is collected by monitoring agents (either its own agents or SNMP agents) and delivered to the monitoring server for processing and storing, where it can be accessed by using the management console. It features centralized configuration and centralized agent upgrades.

Likewise Open : joins Linux, Unix, & Mac OS machines to Microsoft Active Directory and securely authenticates users with their domain credentiials

Likewise Open is an application that joins Linux, Unix, and Mac OS machines to Microsoft Active Directory and securely authenticates users with their domain credentials. Features include: joining non-Windows systems to Active Directory domains in a single step from the command line or from a GUI; authenticating users with a single user name and password; enforcing the same password policies for all platforms; supporting multiple forests with one-way and two-way cross forest trusts; caching credentials in case your domain controller goes down; and providing single sign-on for SSH and Putty. It does not require Active Directory schema changes for installation.

Service Guardian aims to protect servers against various things such as resource exhaustion and connection floods

Service Guardian aims to protect servers against various things such as resource exhaustion and connection floods. It can measure the number of connections to servers' ports and, after a grace time period, compares and sees if the host is still in violation of the specified settings. If a host is in violation of the settings, it will be filtered out and dropped via netfilter/iptables.

Sshguard monitors services through their logging activit

Sshguard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication.

pam_passwdqc : A simple password strength checking module for PAM-aware password changing programs, such as passwd

pam_passwdqc is a simple password strength checking module for PAM-aware password changing programs, such as passwd(1). In addition to checking regular passwords, it offers support for passphrases and can provide randomly generated ones. All features are optional and can be (re-)configured without rebuilding. The package additionally includes libpasswdqc (a password/passphrase strength checking library), pwqcheck (a standalone password/passphrase strength checking program), and pwqgen (a standalone random passphrase generator program).

collectd : A small and modular daemon which collects system information periodically and provides means to store the values

collectd is a small and modular daemon which collects system information periodically and provides means to store the values. Included in the distribution are numerous plug-ins for collecting CPU, disk, and memory usage, network interface and DNS traffic, network latency, database statistics, and much more. Custom statistics can easily be added in a number of ways, including execution of arbitrary programs and plug-ins written in Perl. Advanced features include a powerful network code to collect statistics for entire setups and SNMP integration to query network equipment.
