Projects / ssh


SSH (Secure Shell) is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. It is intended as a replacement for rlogin, rsh, rcp, and rdist.

            Perhaps you are looking for Portable OpenSSH or FreeSSH?

            OpenSSH is a FREE version of the SSH protocol suite of network
            connectivity tools that increasing numbers of people on the Internet
            are coming to rely on. Many users of telnet, rlogin, ftp, and other such
            programs might not realize that their password is transmitted across
            the Internet unencrypted, but it is. OpenSSH encrypts all traffic
            (including passwords) to effectively eliminate eavesdropping,
            connection hijacking, and other network-level attacks. Additionally,
            OpenSSH provides a myriad of secure tunneling capabilities, as well
            as a variety of authentication methods.

            OpenSSH is an OpenBSD project and *Portable* OpenSSH covers:
            AIX, HP-UX, Irix, Linux, NeXT, SCO, SNI/Reliant Unix, Solaris,
            Digital Unix/Tru64/OSF, MacOS X, Cygwin and more . . .


            There is a fab Windows SSH client called PuTTY which does
            excellent terminal emulation and works perfectly with
            Midnight Commander. Also Windows GUI front-ends for
            the SSH file transfer program.

            Likewise SSH clients and servers, for Mac, PalmOS, Java . . .
            MSDOS, Windows CE, BEOS, VMS, RISCOS . . .


            Apparently ownership of the trademark "SSH" is in dispute,
            so not every station in the SSH firmament will help you find
            the others.

            Nobody uses SSH - what?!
            Hate to disagree Jeff, but LOTS of corporations use SSH because of the support contracts available (we have hundreds of copies running at my workplace). And while I agree that open-source workers may prefer OpenSSH for philosophical reasons, don't assume that it works for everyone. SSH is a fine product...

            Problems with 1.X
            I just tried the 2.X series (2.0.13) and I can't connect to my university (they're using 1.X) claiming "Illegal Protoco Version", although I edited the /etc/ssh2/ssh2_config allowing ssh1 conns and was using ./configure options to ensure compatibility.
            So I will downgrade, what a shame.
