ABSTRACT

This document describes a new file transfer service for the Internet based on Telnet Protocol for option negotiation and Kermit Protocol for file transfer and management. The Internet Kermit Service provides access to both authenticated and anonymous users. The use of Kermit protocol over a Telnet connection provides several advantages over FTP, including easy traversal of firewalls, transfers over multiple transports, and security via a combination of supported Telnet authentication and encryption option negotiations, plus significant functional benefits. While this document describes a new service for the Internet, the clients for this service already exist on most platforms in the form of Telnet clients that support the Kermit file transfer protocol. These clients are available not only from Columbia University’s Kermit Project but also numerous third parties.
