Operating primarily on port 1666 over TCP, Perforce facilitates efficient code collaboration, asset management, and change tracking across distributed teams. It supports branching, merging, access control, and integrations with various development tools, making it a crucial tool for enterprises and organizations requiring robust version control capabilities.

ZangZing Agent

ZangZing Agent was part of ZangZing's photo-sharing service, enabling synchronization between a user's local device and the ZangZing cloud platform. The agent facilitated communication, upload, and download of images, automating the management of photo albums across devices and the online service.

WinMX P2P Chat

Port 6257 is associated with WinMX, a popular peer-to-peer (P2P) file sharing and chat application primarily used on Windows systems in the early 2000s. This port facilitates chat services within the WinMX network, supporting user conversations and coordination across the decentralized system.

Laplink

Laplink is a proprietary file transfer software originally designed to simplify migrating files and settings between PCs. It leverages this dedicated port to establish connections between devices, enabling quick, user-friendly migration or synchronization tasks without needing extensive configuration.

CVSup

CVSup is a network utility designed primarily for synchronizing source trees between a central repository and client systems. It efficiently manages file transfers, supporting incremental or partial updates to reduce bandwidth consumption. Mainly used in FreeBSD development environments, CVSup helps ensure that developers and users maintain up-to-date versions of source code more reliably than traditional downloading methods.

CoMotion Backup

CoMotion Backup is a network service that facilitates distributed file sharing and backup functionalities. It is primarily used within enterprise environments to provide redundancy, data protection, and versioning capabilities over TCP and UDP transports. While it is a relatively uncommon service today, it was once deployed to optimize collaborative workflows and ensure data persistence through backup synchronization.
