What is an SSH Client?

 

New call-to-action

SSH Clients: Definition

An SSH client is a program that allows establishing secure and authenticated SSH connections to SSH servers.

SSH client software is available for major enterprise environment operating systems, such as Unix variations, Microsoft Windows and IBM z/OS.

Cyberduck - SFTP/FTP Client for Mac

Cyberduck is a fairly popular file transfer client for Apple Mac and Microsoft Windows. It supports FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive and Dropbox.

Cyberduck was built by David V. Kocher, Yves Langisch, and iterate GmbH.

Downloading Cyberduck

Cyberduck can be downloaded from https://cyberduck.io/.

Security Alert

Cyberduck can use public keys for authentication. Many organizations have been found to have massive numbers of unmanaged SSH keys. They pose a major security and compliance risk. More information on SSH Key Management >

Opening SSH tunnels from the external Internet into organizations has also become a common way to circumvent security policies and open backdoors. More information on SSH Tunneling >

Filezilla - SSH and FTP Client

The FileZilla project is an open source development initiative behind the “FileZilla Free FTP Solution”. The project made its first release in 2001. The software is still distributed free of charge under the terms of the GNU General Public License.

FileZilla is well-suited for small-scale file transfer requirements. There is no commercial support, so each user is on their own. The FileZilla community has web forums, Wiki, and bug tracking systems which provide assistance.

FileZilla supports multiple protocols

FileZilla is a cross-platform implementation of the FTP, SFTP, and FTPS protocols. In addition to the unprotected plaintext file transfers it also supports the SFTP and FTPS secure file transfer protocols. For secure file transfers the server-side naturally needs to also support the selected secure protocol. The FileZilla SFTP client is fully interoperable with the Tectia SFTP servers.

FileZilla provides end-users with a graphical user interface that provides desktop end users with a familiar and easy user experience.

Multiplatform support

The FileZilla client software is available for the common desktop operating systems. Installation packages are available for download for Windows and MacOS. For the Linux operating systems the FileZilla project provides both the source code of the client applications as well as pre-compiled binary packages in the native package management systems of various Linux distributions.

A FileZilla server implementation is available for the Windows operating systems for Windows Vista and newer versions. There is a version for both 32- and 64-bit platforms for each operating system version.

To download FileZilla, go to the project download page.

Alternatives for FileZilla

Modern SSH clients, such as Tectia SSH offer file transfers integrated with a terminal client. The FTP and FTPS protocols shouldn't really be used anymore, as they are quite insecure or aren't as robust as SFTP.

Please see the SSH clients page for a list of alternatives for various platforms.

PuTTY

PuTTY is a versatile terminal program for Windows. It is the world's most popular free SSH client. It supports SSH, telnet, and raw socket connections with good terminal emulation. It supports public key authentication and Kerberos single-sign-on. It also includes command-line SFTP and SCP implementations.
