pbnc runs in userland and acts as a simple TCP port forwarder. It has a single-threaded design (uses select(), does not fork). It can handle multiple targets with an unlimited number of clients (at least in theory), and supports simple IP-based access control. Since pbnc works on network level, it does not care about the application protocol. It can tunnel FTP (control connection), SSH, HTTP and all other protocols using TCP communication. Application-level SSL/TLS encryption is also no problem.

Suck and blow are simple companion utilities for sending data over a TCP socket. They are easy to use and appropriate when FTP is unavailable, or too much of a hassle, e.g., in single-user mode, from within shell scripts, etc. Blow reads the data from standard input, while suck writes it to standard output. Either program may originate the TCP connection, and the TCP port may be specified if desired.

Chaosreader is a perl script that parses snoop or tcpdump logs and extracts sessions for a number of different appplications: ssh, telnet, smtp, irc, ftp, etc. The data are formatted into an html file and can be used to replay some sessions. Sshkeydata is a perl script that attempts to recreate ssh sessions extracted by chaosreader by estimating what commands may have been typed. Both scripts are installed in ${PREFIX}/bin

M2Crypto is the most complete Python wrapper for OpenSSL featuring RSA, DSA, DH, HMACs, message digests, symmetric ciphers (including AES); SSL functionality to implement clients and servers; HTTPS extensions to Python's httplib, urllib, and xmlrpclib; unforgeable HMAC'ing AuthCookies for web session management; FTP/TLS client and server; S/MIME; ZServerSSL: A HTTPS server for Zope and ZSmime: An S/MIME messenger for Zope.

KDiff3 is a program that: * compares or merges two or three text input files or directories, * shows the differences line by line and character by character (!), * provides an automatic merge-facility and * an integrated editor for comfortable solving of merge-conflicts, * supports KIO on KDE (allows accessing ftp, sftp, fish, smb etc.), * Printing of differences, * Manual alignment of lines, * Automatic merging of version control history (cvs Log keyword), * and has an intuitive graphical user interface.

cadaver: command-line DAV client. Like the original ubiquitous command-line FTP client except for WebDAV instead. Uses the sitecopy (http://www.lyra.org/sitecopy/) WebDAV code. Commands: open, close, cd, ls, get, put, mkcol, delete, copy, move, cat, less. Please send in bug reports, feature requests or any questions to the discussion list, cadaver@webdav.org.

Passwd is the Horde password changing application. While it has been released and is in production use at many sites, it is also under heavy development in an effort to expand and improve the module. Right now, Passwd provides fairly complete support for changing passwords via Poppassd, LDAP, Unix expect scripts, the Unix smbpasswd command for SMB/CIFS passwords, Kolab, ADSI, Pine, Serv-U FTP, VMailMgr, vpopmail, and SQL passwords.

Middleman is a robust proxy server with many features designed to remove unwanted content, increase privacy, and to simply make surfing the Web a more pleasant experience. Some of the highlights of Middleman include banner and popup blocking, HTTP and FTP content caching, NTLM and Basic authentication when forwarding through another proxy server, regular expression substitution in downloaded files and HTTP headers, complete support for HTTP/1.1 including persistent connections and gzip encoding, and an intuitive Web interface for configuring the proxy.

The wikiCalc program lets you make web pages with more than just paragraphs of prose. It combines the ease of authoring and multi-person editing of a wiki with the familiar visual formatting and calculating metaphor of a spreadsheet. Written in Perl and released under the GPL 2.0 license, it can easily be setup to run on almost any server as a web application or on a personal computer to publish by FTP.

This program is for any user who retrieves ftp files via ftpmail or bitftp servers. It runs quietly in the background and watches the user's mail directory. When the mail- retrieved file has arrived in full, rftp puts the pieces together in order and stores the tarball in a directory. I wrote this several years ago when my only link to the Arpanet was a uucp link. These days, most FreeBSD users have a direct link to the net. For the dozens or hundreds who don't this should be of use.
