TCPware

TCPware was a proprietary TCP/IP software stack developed by Process Software Corporation for the OpenVMS operating system. It provided a comprehensive suite of networking services, allowing OpenVMS systems to communicate with other systems using the TCP/IP protocol suite.

TCPware was designed to integrate tightly with OpenVMS, leveraging its features for security, process management, and resource allocation. It offered a wide range of applications and utilities, including:

• FTP (File Transfer Protocol): For transferring files between systems.
• Telnet: For remote login to other systems.
• SMTP (Simple Mail Transfer Protocol): For sending and receiving email.
• DNS (Domain Name System): For resolving domain names to IP addresses.
• NFS (Network File System): For sharing files across a network.
• Web Server: For hosting websites.

TCPware competed with other TCP/IP stacks for OpenVMS, such as DECnet-Plus and MultiNet. It was known for its performance, reliability, and comprehensive feature set. Process Software was acquired by HP (Hewlett-Packard) in 2004. HP continued to support and develop TCPware for a period before eventually phasing it out in favor of other networking solutions.
