===== What is a Secure Shell? ===== /* //(from http://freessh.org)(broken)// "SSH (secure shell) is a internet protocol that allows a user to connect to a remote host via an encrypted link. " */ Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel over an insecure network: a server and a client. A secure shell client allows you to connect to a remote computer. If you wish to access the Vasser CS Department Unix system outside of the lab, you will need to use a secure shell. The secure utilities correspond to older, non-secure counterparts. For example: * **ssh** A replacement for telnet. Allows you to "Log in" and have an interactive text connection to another computer. * **scp** A replacement for rcp. Using scp, you can quickly copy files between computers over a network securely. * **sftp** A replacement for ftp. Ftp, the file transfer protocol, has traditionally been used to browse file systems for download, and optionally allowing uploading to the server. ===== Using Secure Utilities ===== Instructions for installing and using these programs are given according to the operating system on your computer. * [[unix|Mac OS X, Unix, and Linux]] * [[windows|Windows]] ===== Common Problems ===== When running emacs from a ssh client, make sure to run it as: \\ "emacs -nw"\\ instead of \\ "emacs &"\\ so that emacs knows to run as a text based interface. ===== More information ===== To find out more about ssh, try visiting http://www.openssh.org. Also, the ssh-faq at http://www.employees.org/~satch/ssh/faq/ssh-faq.html covers a lot of common ssh questions. ===== Having problems? ===== Contact Ben (ben_at_cs_dot_vassar_dot_edu) for help conecting to the Computer Science computer system. Please include your operating system, ssh software you're trying, and anything that seems to be amiss. --- //[[ben@cs.vassar.edu|Ben Stoutenburgh]] 2012/11/08 15:37/
