Frunk is a simple program that detects and reports interface status changes using SNMP. Basically, it detects if one or more of a set of pre-configured interfaces are up or down and reports the fact by emailing alerts. It is good for monitoring several interfaces on several devices, normally routers, and checking for link failures. It also optionally creates and constantly updates an HTML document containing information on those interfaces which are down.
ZeroShell is a Linux distribution with Web administration aimed at providing the main network services a LAN requires: Kerberos and x.509 authentication, LDAP and RADIUS authorization, routing, bridging, VLAN 802.1q management, VPN LAN-to-LAN and host-to-LAN, support for authenticated WI-FI access with WPA and WPA2, DNS and DHCP servers, and Captive Portal to access the network using Web login (Internet hotspot). The distribution is now available in the form of a LiveCD or Compact Flash image for embedded network devices. The image size is 103 MB. The distribution is produced directly from the source code of any installed packages.
Project Open ESB implements an Enterprise Service Bus (ESB) runtime with sample service engines and binding components. Open ESB allows you to easily integrate enterprise applications and Web services as loosely coupled composite applications. This allows you to seamlessly compose and recompose your composite applications, realizing the benefits of a true Service-Oriented Architecture (SOA). The core of the Open ESB SDK is based on Java Business Integration (JBI) technology, as defined in the JSR 208 specification.
libss7 is a userspace library for providing SS7 protocol services to applications. It has a working MTP2, MTP3, and ISUP for ITU and ANSI style SS7, but was written in a manner that will easily allow support for additional national specific variants in the future. For a working reference implementation, see the various link test programs, as well as the Asterisk Open Source PBX.
VectorSpace Database (VSDB) provides multi-dimensional similarity search capability in a robust server package. It is a server that allows any socket-capable programming language to post and search vectorspaces of multi-dimensional data. Data can be of any base datatype (e.g. text, objects, dating profiles, sessions, ecommerce orders, etc.). VSDB also offers a clustering capability that can display groupings of data based on common dimensions. A built-in thesaurus feature can help bridge multiple-similar-dimensions in search or clustering.
