BBSzilla is an extension for Mozilla-based browsers such as the Mozilla Application Suite and Firefox. It gives the browser the ability to connect to Bulletin Board Systems that utilize TCP/IP, such as Hotline servers. There is functionality for multi-user chat, single-user messaging, as well as server-side and P2P file sharing, threaded news, single-thread bulletins, and more.
Sharity mounts shares exported by Windows, Samba, and other SMB/CIFS servers in the file system of Unix computers. It implements Resource Browsing, which is similar to the Windows Network Neighborhood (Netbios Workgroups and Active Directory), NTLM, NTLMv2, and Kerberos authentication, Microsoft's Distributed File System (DFS), and manipulation of Access Control Lists (ACLs).
pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
