Oddjob is a Java job scheduler and task automation framework. A GUI designer or XML are used to define a hierarchy of jobs. Sequential, parallel, and conditional execution (or combinations) allow for nearly any business process to be modelled. Oddjob can run on the desktop or on a server and uses JMX to control remote instances via an Explorer-style GUI. Basic Web-based monitoring is also available. It can be embedded in client code and is easily extensible via a simple API.
libssh is a C library to access SSH services from a program. It can remotely execute programs, transfer files, and serve as a secure and transparent tunnel for remote programs. Its Secure FTP implementation can play with remote files easily, without third-party programs other than libcrypto (from OpenSSL) or libgcrypt.
UDPCast allows to send data simultaneously to many destinations on a local net. This can for instance be used to install entire classrooms of PCs at once. The advantage over using other methods (nfs, ftp, whatever) is that udpcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install 2. The tool comes with a busybox bootdisk for easy loading of the tool. However, udpcast can also be started from the command line of an already installed system, and can be used for other purposes than just system installation.
Super Flexible File Synchronizer lets you back up your data and synchronize PCs, Macs, servers, notebooks, and online storage space. You can set up as many different jobs as you need and run them manually or by using the scheduler. The software works with local hard drives and any other mounted volumes. In addition, it comes with support for FTP, SSH, HTTP, WebDAV, Amazon S3, and Google Docs. You can use Zip compression and data encryption. There are powerful synchronization modes, including Standard Copying, Exact Mirror, and SmartTracking.
tnftp (formerly known as lukemftp) is a port of the NetBSD FTP client to other systems. It offers many enhancements over the traditional BSD FTP client, including command-line editing, command-line fetches of FTP and HTTP URLs (including via proxies), command-line uploads of FTP URLs, context-sensitive word completion, dynamic progress bar, IPv6 support, modification time preservation, paging of local and remote files, passive mode support (with fallback to active mode), SOCKS support, TIS FWTK gate-ftp server support, and transfer rate throttling. tnftp is the default FTP client found in FreeBSD, MacOS X, NetBSD, and SuSE Linux.
BIE (Business Integration Engine) is an open source integration system that makes it easy for organizations to exchange data with external trading partners regardless of their native applications. It competes in the same space as applications like Microsoft BizTalk except that it is truly cross-platform since it written in Java.
