The Objeck computer language is an object-oriented computing language with functional features that has ties with Java, C#, and Pascal. In this language, all data types are treated as objects. The language consists of a compiler and VM with an accompanying memory management and JIT compiler.
Sshguard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication.
Zsh is a UNIX command interpreter (shell) which of the standard shells most resembles the Korn shell (ksh). It includes enhancements of many types, notably in the command-line editor, options for customising its behaviour, filename globbing, features to make C-shell (csh) users feel more at home and extra features drawn from tcsh.
PHP MIME Mail decoder class is a PHP class to parse and decode MIME email messages. It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format. It can decode messages read from files or data strings. The bodies of multipart messages can be decoded into distinct sub-messages. Optionally, the message body data can be saved to separate files, so the class can handle messages larger than the available memory. The parser can tolerate some syntax errors in malformed messages that are not compliant with RFC 2822.
The OpenCA OCSP Responder is an RFC 2560 compliant OCSPD responder. It can be used to verify the status of a certificate using OCSP clients (such as Mozilla/Netscape7). The Responder is actually included in the main OpenCA distribution package. It is also possible to install the daemon as a stand-alone application, in which case you will need a CRL (or access to an LDAP server where the CRL can be obtained).
m0n0wall is an all-in-one firewall software package that is based on FreeBSD. It is geared towards embedded PCs, but it also works on standard PCs. It includes an easy-to-use Web interface like commercial firewall boxes do. PHP is used instead of shell scripts, and the entire system configuration is stored in a single XML-formatted file. There is support for VPN, traffic shaping, captive portal, VLANs, and more.
