scponly is an alternative "shell" of sorts for system administrators who would like to provide access to remote users to both read and write local files without providing any remote execution priviledges. Functionally, it is a wrapper around the ssh suite of applications. It is typically used by creating a user whose shell is set to scponly. This user can neither login interactively nor execute commands remotely, but it can use scp and sftp to download and upload files to the computer, governed by the usual Unix file permissions.
The sctplib library is a fairly complete prototype implementation of the Stream Control Transmission Protocol (SCTP), a message-oriented reliable transport protocol that supports multi-homing and multiple message streams multiplexed within an SCTP connection. The API of the library was modeled after section 10 of RFC 2960, and most parameters and functions should be self-explanatory to the user familiar with this document. In addition, the library also provides a number of helper functions for managing timers and UDP communication.
