Opsview Core is a network monitoring software application. It solves the challenges of monitoring modern IT and network systems. It is a drop-in replacement for Nagios Core, with full support for its plugins and 100% compatibility. It is easy to install and configure and is ideal for monitoring applications networks, and Windows, Linux, and Unix servers. VMWare, KVM, Xen, and Microsoft Hyper-V are supported, and Amazon EC2 and other cloud services can be monitored. It works with Opsview Mobile to allow you to monitor your systems on the go.
check_mssql_health is a plugin for Nagios that allows you to monitor an MS SQL Server. Among the list of metrics are time to login, buffer cache hit rate, page life expectancy, full table scan rate, free space in databases, batch requests/second, and many more. Installation of the DBD::Sybase Perl module is required.
dhcpy6d delivers IPv6 addresses for DHCPv6 clients, which can be identified by DUID, hostname, or MAC address, as in the good old IPv4 days. Addresses may be generated randomly, by range, or by arbitrary ID or MAC address. Clients can get more than one address, leases and client configuration can be stored in databases, and DNS can be updated dynamically.
Skylable SX is a reliable, powerful, fully distributed cluster solution for your data storage needs. It can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. It has built-in support for deduplication, client-side encryption, on-the-fly compression, and much more.
Amatix Office is a complete communication platform for small and medium-sized businesses. It provides email, calendar, contacts, conventional telephony like ISDN, new generation VoIP telephony like SIP, instant messaging, presence, and other features needed to power a business. Amatix Office is very easy to install and use and does not require any special IT skills. It is a live software appliance which boots a computer directly from a CD or USB flash drive without any software installation.
Syncless is an experimental, lightweight, non-blocking (asynchronous) client and server socket network communication library implemented in Stackless Python 2.6. It contains an asynchronous DNS resolver (using dnspython) and an HTTP server capable of serving WSGI applications. It aims to be a coroutine-based alternative of event-driven networking engines (such as Twisted and FriendFeed's Tornado). It is already about that fast, but it has fewer features and is less stable now.
sessiond allows a cluster of SSL/TLS servers to share their session caches in order to prevent each node of the cluster from negotiating a separate session. SSL/TLS session is basically a set of secret values (symmetric encryption keys, MAC secrets) shared between a client and a server. The use of asymmetric cryptography required to establish new sessions is the main performance bottleneck of the SSL/TLS protocol.
