Unison is a file-synchronization tool for Unix and Windows, written in OCaml. It allows two replicas of a collection of files and directories to be stored on different hosts, modified separately, and then brought up to date by propagating the changes ... [More] in each replica to the other. Unison offers several advantages over various synchronization methods such as CVS, Coda, rsync, Intellisync, etc. Unison can run on and synchronize between Windows and many UNIX platforms. Unison can synchronize changes to files and directories in both directions, on the same machine, or across a network using ssh or a direct socket connection. Transfers are optimised using a version of the rsync protocol, has a clear and precise specification, and is resilient to failure due to its careful handling of replicas. [Less]

The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution that is sponsored by Endian. [Less]

The Shoreline Firewall, more commonly known as "Shorewall", is a high-level tool for configuring Netfilter. You describe your firewall/gateway requirements using entries in a set of configuration files. Shorewall reads those configuration files and ... [More] with the help of the iptables utility, Shorewall configures Netfilter to match your requirements. Shorewall can be used on a dedicated firewall system, a multi-function gateway/router/server or on a standalone GNU/Linux system. Shorewall does not use Netfilter's ipchains compatibility mode; as a consequence, Shorewall can take advantage of Netfilter's connection state tracking capabilities to create a stateful firewall.
