Dante is a free implementation of the proxy protocols SOCKS version 4 and SOCKS version 5 (RFC 1928). It can be used as a firewall between networks, controlling outgoing traffic. The package consists of two parts: a socks server and a proxy client that supports socks, HTTP proxies, and UPnP. RFC 1961 (GSSAPI) is supported in both the client and the server. Commercial support is available.
Usermin For Webmail is a modified version of the Usermin package that is pre-configured for use as a Web-based email client. It is designed to work on systems running a local IMAP server, such as Dovecot. By default, users can read email, setup autoresponders and forwarding with Procmail, filter mail with simple rules, change their passwords, and manage folders.
mod_ssl provides provides strong cryptography for the Apache 1.3 webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1). It is based on the SSL/TLS toolkit OpenSSL and supports all SSL/TLS related functionality, including RSA and DSA/DH cipher support, X.509 CRL checking, etc. Additionally it provides special Apache related facilities like DBM and shared memory based inter-process SSL session caching. per-URL SSL session renegotiations, DSO support, etc.
BitchX is the premiere IRC (Internet Relay Chat) client. It originally was a modified version of the popular ircII client, and the features were eventually merged into the EPIC IRC client. The current development is aimed at merging the client back to a current branch of EPIC and bringing compatibility and stability back to the client, while bringing the features that are BitchX into a new client.
UMLGraph facilitates the declarative specification and drawing of UML class and sequence diagrams. One can specify a class design using the Java syntax complemented by Javadoc tags. Running the UmlGraph doclet on the specification generates a Graphviz diagram specification that can be automatically processed to create Postscript, GIF, SVG, JPEG, fig, or Framemaker drawings. Similarly, sequence diagrams are specified using declarative pic macros and compiled with the GNU plotutils pic2plot program into a PNG, PNM, (pseudo) GIF, SVG, AI, Postscript, CGM, FIG, PCL, HPGL, Regis, or TEK drawing.
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
