Audiogalaxy's Satellite is a distributed music search agent. It is a small application which does mp3 searching and file transfer and makes a designated directory on your computer searchable by other Satellite users. It features a real-time transaction-based system for file sharing. The Linux version has no user interface, but files are selected via the Web for transfer from other users.
cfv is a utility to both test and create .sfv (Simple File Verify), .csv, .crc, .md5(sfv style), md5sum, BSD md5, sha1sum, and .torrent checksum verification files. It also includes test-only support for .par and .par2 files. These files are commonly used to ensure the correct retrieval or storage of data.
ClusterNFS is a set of patches for the "Universal NFS Daemon" (UNFSD) to allow multiple clients to nfs mount the same root filesystem by providing "tagged" filenames. When a client requests the file "/path/filename", the ClusterNFS server checks for the existence of files of the form "/path/filename$$TAG=value$$". If such a file exists and the client has a matching value for KEY, this file is returned. If the client does not have a matching value or no such file exists, the file request proceeds as normal. Currently supported keys include HOST (hostname), IP (IP number), CLIENT (matches any nfs client) and CREATE (for "tagged" creation of files).
Gtk-Gnutella is a full-featured Gnutella client using GTK+. It contains all widely deployed Gnutella features, including DHT support. It is extremely efficient, using little CPU time and memory. It is meant to be left running 24x7. It is fully compatible with UPnP and NAT-PMP, and as such is easy to use behind a firewall supporting one of these port mapping technologies.
