apache-privsep - Apache Privilege Separation for WebDAV Remote Access

apache-privsep is a patch to Apache and mod_dav that addresses the problem of an Apache DAV server only being able to write files as the apache user (usually something like 'nobody' or 'www') and it does so in a very secure way. The Apache Privilege Separation patches applies similar principals of privilege separation to that of sshd.

JSON-RPC-Java - JavaScript to Java AJAX communications library

JSON-RPC-Java is a dynamic JSON-RPC Java bridge that allows you to transparently call server-side Java code from Javascript. There should be no changes necessary to your existing server-side Java code to allow calling from JavaScript (such as marshalling and unmarshalling of special types) as JSON-RPC-Java dynamically maps JavaScript Objects to Java Objects by dynamic reflection on Java method signatures and dynamic mapping between Java Objects and JavaScript objects. It maps the loosely typed JavaScript objects to Java objects by reflecting on the Java method signatures and matching the fields of JSON objects to Java primitive types, arrays and complex objects such as Java Beans.

JSON-C - JSON implementation in C

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON formatted strings and parse JSON formatted strings back into the C representation of JSON objects.

JMemProf - Java Web-based Memory Profiler

JMemProf is a live Java memory profiler suitable for deployment in web containers such as JBoss, Tomcat and other web containers. JMemProf allows you to retrieve memory profile information while your application is running. JMemProf is implemented in C using the JVMPI (JVM Profiling Interface). There are two parts, a shared object loaded into the JVM at startup, and a WAR file containing a Java servlet that uses a JNI interface to the profiling extension to retrieve and display memory profile information collected during execution.

safte-monitor - SCSI enclosure monitor for Linux

safte-monitor reads disk enclosure status information from SAF-TE capable enclosures (SCSI Accessible Fault Tolerant Enclosures), which is common in many SCSI disk enclosures these days. safte-monitor can monitor multiple devices and will probe for and detect them. The information retrieved includes power and fan status, temperature, audible alarm, drive faults, array critical/failed/rebuilding state, and door lock status. safte-monitor logs information to syslog and can execute a program with details of the component failure. It also includes an embedded web server.

mapscsi - Linux SCSI device mapping tool

mapscsi is a small utility that creates a consistent mapping to Linux scsi devices. mapscsi achieves this by creating symbolic links to linux scsi disk devices after scanning all scsi disk devices, finding out their host, channel, id, lun, pci location (if available), Fibre Channel world wide node and port names, loop and port ids (with qla2x00 v4.46.5 driver) vendor, product and serial number details and using this information plus a mapping rules file containing device templates to dynamically create link names.
