Fugu SSH is a Mac OS X graphical frontend to OpenSSH's Secure File Transfer application (SFTP). SFTP is similar to FTP, but, unlike FTP, the entire session is encrypted, meaning no passwords are sent in cleartext form, and it is thus much less vulnerable to third-party interception. Fugu allows you to take advantage of SFTP's security without having to sacrifice the ease of use found in a GUI. Fugu also includes support for SCP files transfers, and the ability to create secure tunnels through SSH.
FullSync is a powerful tool that helps you keep multiple copies of various data in sync. It can update your Web site using FTP and SFTP, back up your data on the local disk or refresh a working copy from a remote server on your local drive using Samba, and much more. It features multiple protocol support, flexible rules, a scheduler, and many other features that give you a solid basis for nearly all situations.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
GNOME Commander is a fast and powerful graphical file manager. It has a "two-pane" interface in the tradition of Norton and Midnight Commander. It features drag'n'drop, GNOME MIME types, FTP, SFTP, and WebDAV using the GnomeVFS FTP module, SAMBA access, the ability to extend the context menu with entries to call external applications or scripts on the selected items, quick device access buttons with automatic mounting and unmounting, a fast file viewer for text and images, a history of recently accessed folders, and folder bookmarks.
GNU Wget is a utility for noninteractive download of files from the Web. It supports HTTP and FTP protocols, as well as retrieval through HTTP proxies. It can follow HTML links, download many pages, and convert the links for local viewing. It can also mirror FTP hierarchies or only those files that have changed. Wget has been designed for robustness over slow network connections; if a download fails due to a network problem, it will keep retrying until the whole file has been retrieved.
GNUSTEP Live CD contains a lot of software for GNUstep, a free implementation of the OPENSTEP framework (which is also directly used in Mac OS X as Cocoa). It includes excellent applications for RAD (GORM and ProjectCenter). The CD is available for i486, AMD64, Apple Mac PowerPC, and Sun UltraSPARC computers.
GSTP is a binary file transfer protocol that focuses on security and anonymity. It tries to do right, where FTP does wrong, especially when it comes to firewall and user/password security. GSTP is based on TLS/SSL and the GSTP package includes a reference client (CLI), a QT GUI client (X11 and Win32), and a server for Unix platforms.
GTransferManager (gtm) allows the user to retrieve multiple files from the Web. These files can be retrieved in multiple parts, and each part retrieved on a separate session when the user is connected to the Internet. This is most useful to users with dialup connections. The program performs these tasks using wget as its backend.
Generic-FTP is an FTP proxy-like application. It can combine multiple FTP servers into a single FTP server front end. You configure what actions you want to be triggered by uploads to specific directories. There are 4 actions provided, but custom actions can be easily created. The "rsync" action transfers the files to a remote rsync server. The "rsynclocal" action copies the file to another directory on the same server. The "smbclient" action copies files to a Windows/Samba share. The "hold" action retains the files in the directory for a specified number of days.
