Unison: Liberation through Data Replication

Unison: Liberation through Data Replication: This document describes some of the benefits of using Unison and provides some tips on doing so, although it is not meant to be a comprehensive how-to guide or user manual.
Another discussion on Using Unison can be found here.
However, neither really answer my current question which is "When using the 'backupdir' parameter in batch mode, do the backups exist on the client/source or server/destination?"

WinSCP :: Freeware SFTP and SCP client for Windows

This is a great app for securely transferring files. It's also great when you'd like to use your Windows text editor (like SciTE) to edit a file out on a Unix or Linux server.

WinSCP is an open source SFTP client for Windows. Its main function is the secure file transfer between a local and a remote computer. Beyond this, WinSCP offers basic file manager functionality. It uses Secure Shell (SSH) and supports, in addition to Secure FTP, also legacy SCP protocol.

tools4ever Free Command Line Tools

Freeware scriptable command line network connectivity tools - I find T4ePortPing especially useful when checking connectivity to devices through a firewall. ICMP may be blocked, but TCP... that's an open book. ;-)

"Looking for a set of powerful command line utilities to integrate in your scripts or in your own application? We have put together a bundle of useful command line utilities for managing your network faster and more efficiently:"

T4eWebPing
Gets the response time and header code for any input URL; great for testing scripts, execution times and 404 errors on your website.
T4ePortPing
Connects to any TCP/IP port and retrieves the response time and error code. You can use this at the command line to check a single IP and port, or in scripts to automatically see which ports are open on your clients or servers.
T4eSQL
Connects to any ODBC database and executes a custom query, results can be written to a text file; useful for database monitoring (systables).
T4eDirSize
Gets the free and used space of any directory or share, also counts the number of special files (encrypted, readonly, hidden, system, etc); great for monitoring free space and file statistics.
T4eRexec
This command line utility is similar to the Windows REXEC command, but accepts a password as input and can therefore run in unattended mode. To run commands on a REXEC compatible OS, such as Linux, the REXEC daemon has to be running on the target system. Note that passwords are transmitted in clear text, for a more secure version look to the SSH versions below.
T4eSSH
A secure implementation of the SSH protocol to get access to a UNIX/Linux operating system. This implementation uses the OpenSSH library and can run in unattended mode when using private and public key files.
T4eUnixInfo
This tool uses the REXEC daemon to remotely execute several pre-defined scripts compatible with Linux, to get system specific information such as DISK, MEMORY, SWAP and CPU. Note that the password to access the remote operating system is transmitted in clear text, look below for a secure SSH implementation.
T4eSSHUnixInfo
This tool uses the SSH daemon to securely execute several pre-defined scripts compatible with Linux, to get system specific information such as DISK, MEMORY, SWAP and CPU. This implementation uses the OpenSSH library and can run in unattended mode when using private and public key files.
