python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly, it wraps the OpenLDAP 2.3+ libs for that purpose. Additionally, the package contains modules for other LDAP-related stuff (such as processing LDIF, LDAPURLs, and LDAPv3 schema).
Vortex Library is an implementation of the RFC 3080 and RFC 3081 standard definitions, known as the BEEP Core protocol, implemented on top of the TCP/IP stack. It comes with complete XML-RPC over BEEP RFC 3529 support, complete support for the TUNNEL profile (which allows you to perform proxy operations for every BEEP profile developed), support for HTTP proxies, and more. The API is consistent, easy to use, and allows you to write application protocols very quickly. The API is designed to allow bindings for other languages to be built easily.
Bandwidth Management Tools is a total bandwidth management solution for Linux and can be used for firewalling, traffic graphing, and shaping. It is not based on any currently-available bandwidth management software and supports packet queues, bursting, complex traffic flow hierarchies, flow groups, traffic logging, and a simple real-time monitoring front-end.
sslh accepts connections in HTTP, HTTPS, SSH, OpenVPN, tinc, XMPP, or any other protocol that can be tested using a regular expression, on the same port. This makes it possible to connect to any of these servers on port 443 (e.g. from inside corporate firewalls, which almost never block port 443) while still serving HTTPS on that port. sslh supports IPv6, privilege dropping, transparent proxying, and much more.
The CyaSSL embedded SSL library is a lightweight SSL library written in ANSI C and targeted for embedded and RTOS environments, primarily because of its small size, speed, and feature set. It is commonly used in standard operating environments and cloud services as well because of its royalty-free pricing and excellent cross platform support. CyaSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2 levels, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as HC-128, RABBIT, and NTRU.
RCP100 is a modular router control plane for Linux platforms. It can be used as a standalone router, or it can be deployed as an embedded router in a virtualized environment. The modular architecture allows rapid introduction of new features and functionality, including support for custom hardware. It features a command line interface, Web interface, Telnet, FTP, and TFTP access, an NTP client and server, a DNS proxy cache, a DHCP relay, static routes, blackhole routes, static ARP, proxy ARP, RIP version 2 (RFC 2082, RFC 2453), OSPF version 2 (RFC 2328), and Access Control Lists.
