Its java needing 1.6 or newer and supports a pile of protocols over the LAN.
Being java it can work on any platform and gives nice and easy access to whatever server you are running from any system. eg windows 7 to access NFS , puppy to windows shares.
I just ran the standalone jar with
java -jar /path/to/jftp.jar
http://j-ftp.sourceforge.net/JFtp is a graphical Java network and file transfer client.
It supports FTP using its own FTP API and various other protocols like SMB, SFTP, NFS, HTTP, and file I/O using third party APIs, includes many advanced features such as recursive directory up/download, browsing FTP servers while transferring files, FTP resuming and queueing, browsing the LAN for Windows shares, and more.
One useful tool if you need to grab or dump some files....
