Syslog4j provides Java components for client and server implementations of the syslog protocol (RFC 3164). UDP/IP, TCP/IP, TCP/IP over SSL/TLS, Unix Syslog, and Unix Socket Logging are supported. Advanced options are provided, including cryptographic message signatures and hashes. It is heavily tested with JUnit and Emma code coverage.
BalanceNG is a modern, IPv6 capable software IP load balancing solution. It is small, fast, and easy to use and set up. It offers session persistence, different distribution methods (Round Robin, Random, Weighted Random, Least Session, Least Bandwidth, Hash, Agent, and Randomized Agent) and a customizable UDP health check agent in source code. It supports VRRP to set up high availability configurations on multiple nodes. It supports SNMP, integrating the BALANCENG-MIB with Net-SNMPD. It implements a very fast in-memory IP-to-location database, allowing powerful location-based server load-balancing.
