Free SSH (Secure Shell) and Telnet Clients / Programs
Listed on this page are free Secure Shell clients, that is SSH clients, as well as telnet clients that allow you to connect to a site via the SSH or Telnet protocols. SSH clients and telnet clients are useful when you need to access the shell of another computer to do things like maintenance, backup, compilation, etc.
Note that if you are looking for a Secure FTP client (SFTP), you should check out the Free Secure FTP and FTP Clients page instead.
Free Secure Shell (SSH) and Telnet Clients
Putty is a well-known open source SSH and telnet client for Windows systems, that supports both SSH1 and SSH2. The package also includes command line tools like PSFTP which allows you to use secure FTP (SFTP, using the SSH protocol) as well as PSCP, an SCP client (for secure file copy). It also supports secure X11 forwarding, which allows you to run X Window applications on the server and view the windows it displays on your local machine. Another useful feature of Putty is secure port forwarding, which allows you to forward arbitrary network connections over your encrypted SSH connection. This can be used, for example, for sending and receiving email securely over a normal SMTP / POP3 connection.

This SSH and SFTP client for Windows has terminal emulation support for bvterm, xterm and vt100 protocols, handles SSPI (GSSAPI) Kerebos 5 and NTLM user authentication and Kerebos 5 host authentication, and supports RSA and DSA public key authentication. SSH port forwarding is also supported as well as an FTP to SFTP bridge that lets you connect to an SFTP server using a program that only handles FTP connections (although I can't imagine why you would want to do that instead of using the included SFTP client, or one of the many other free SFTP clients around). As far as I can tell, at the time I write this, the program is free for individual use for up to 4 people/machines in a home (but you should read their licence agreement yourself to be sure).
The OpenSSH comes with the ssh program (secure shell), scp (for secure file copy), sftp (for secure FTP), etc. It has ports for a variety of systems, including OpenBSD (of course), Linux, Solaris, FreeBSD, AIX, HP-UX, etc.
- SSHWindows (OpenSSH for Windows)
This is an OpenSSH port for Windows. It doesn't look like it's maintained any more.
Cygwin contains a port of OpenSSH for Windows. Note: if you only want OpenSSH, don't select the other Unix tools in the package when you install.
