ColdSync is a portable synchronization tool for Palm devices (PalmPilot, Handspring Visor, etc.) that runs under *BSD, Solaris, Digital Unix/Tru64, Linux, AIX, and Windows NT. It supports PalmOS 2.0 (original PalmPilot) and later. It is only known to support Visor syncing under FreeBSD and Linux, however. It supports IR syncing under Linux. ColdSync can back up, restore, install, and synchronize database, and can be extended and customized through the use of conduits. ColdSync is rather paranoid and takes pains not to delete anything it isn't 100% sure about.
TAP provides packet reception and transmission for user-space programs. It can be viewed as a simple Ethernet device, which instead of receiving packets from a physical medium, receives them from a user-space program and instead of sending packets via physical media, writes them to the user-space program.
Monit is a utility for managing and monitoring processes, programs, files, directories, and devices on a Unix system. It conducts automatic maintenance and repair and can execute meaningful causal actions in error situations. It can be used to monitor files, directories, and devices for changes, such as timestamps changes, checksum changes, or size changes. It is controlled via an easy to configure control file based on a free-format, token-oriented syntax. It logs to syslog or to its own log file and notifies users about error conditions via customizable alert messages. It can perform various TCP/IP network checks, protocol checks, and can utilize SSL for such checks. It provides an HTTP(S) interface for access.

SNTS (Simple Network Time Sync) is a simple, fast, and low-overhead time syncronization system for LANs. It is designed as a simple replacement for timed with better time control and better portability (for systems without a standard adjtime() call, such as Linux). It uses broadcasts to negotiate servers and set time, and allows multiple groupings of servers on a network for independent time management for groups or labs. SNTS also supports multiple servers in a single group.
