ssh - Secure Shell

ssh is a secure, encrypted, alternative to rsh, rlogin and rcp. It may be used as an alternative to telnet and ftp.

What's the Point ?

See the SSH homepage for more detail and download information. ssh is available for Unix from many ftp sites , e.g. sunsite.unc.edu and for Windows from www.datafellows.com or SecureCRT from VanDyke.
See also guardian ssh.
See also Cedomir Igaly's SSH page for a free Win95 client and Crypt.DLL. scp is not supported, though, but it may be possible to tunnel HTTP or ftp through a secure port. This seems to work with wsftp32. To use this, in ssh config select Local Forwards and tunnel local port 8021 to remote port 21 (using remote host). In wsftp32 connect config, select advanced, select port 8021, and check Passive Transfers, then save the profile. Voila, you can now ftp to a Unix box without your data & password going in clear!

For Mac, see NiftyTelnet 1.1 SSH ( Jonas Walldén) or BetterTelnet which may support RSA legally for US users.

X-11: MIT cookie-based X-11 forwarding seems to be broken in StarNet X-Win; however, adding the local computer name to the allowed X-hosts list may allow encrypted X-11 to work with ssh.

Tips & Tricks

To open a secure xterm: xterm -sb -T Alph04 -e ssh -l myname alph04.triumf.ca &

To copy a file: scp myname@alph04.triumf.ca:/path/file .

To copy several files: scp 'myname@alph04.triumf.ca:/path/*' . (use quotes to protect wildcards).

To open an xterm and tunnel IMAP: xterm -sb -T Alph04 -e ssh -l myname -L 8143:localhost:143 alph04.triumf.ca &
(connect to IMAPD on localhost:8143 - avoids sending password in clear. May work for POPD. In .pinerc can say e.g. wwwT {localhost:8143}/home/myname/mail/www-talk)
