What Are SSH Clients for Windows, Mac, and Unix

  • PuTTY is a free open-source terminal emulator which lets you initiate interactive command-line sessions to UITS Unix servers. It can act as a client for the SSH, Telnet, rlogin, and raw TCP computing protocols and as a serial console client. Version 0.63
  • WinSCP is a free open-source SFTP and FTP client for Windows. Its main function is to secure file transfer between a local and a remote computer. Beyond this, WinSCP offers scripting and basic file manager functionality. Version 5.5.5
  • Tera Term Pro is a free open-source, software implemented, terminal emulator program. Tera Term Pro with its SSH extension (TTSSH) is one of the recommended UNIX terminal applications available for Windows users. This telnet client provides VT100 emulation, selected VT200/300 emulation, TEK4010 emulation and Kermit, XMODEM, ZMODEM, B-PLUS and Quick-VAN file transfer protocols. It emulates different types of computer terminals, from DEC VT100 to DEC VT382. Version 4.84
  • Cyberduck is a libre server and cloud storage browser for Mac and Windows with support for FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive and Dropbox.
  • Open SSH for Unix

If you need to run multiple sessions in one console, this is a great option for your. A: Generally, if you configure multiple keys for an SSH client and connect to an SSH server, the client can try the keys one at a time until the server accepts one. However, this doesn't work with Azure DevOps for technical reasons related to the SSH protocol and how our Git SSH URLs are structured.

Why Use SSH Clients

  1. $ ssh -Q mac # output would be something like hmac-sha1 hmac-sha1-96 hmac-sha2-256 hmac-sha2-512 hmac-md5 hmac-md5-96 umac-64@openssh.com umac-128@openssh.com So now in order to connect to target server with their choice of mac which your server doesn't support you have to explicitly provide one of the mac supported by target server.
  2. The OpenSSH SSH client supports SSH protocols 1 and 2. Protocol 2 is the default, with ssh falling back to protocol 1 if it detects protocol 2 is unsupported. These settings may be altered using the Protocol option in sshconfig(5), or enforced using the -1 and -2 options (see above). Both protocols support similar authentication methods, but protocol 2 is preferred since it provides.

SSH uses encryption to prevent eavesdroppers from reading information, such as your password, from the network. All SSH-type software allows for secure communication, replacing the vulnerable utilities like telnet, rlogin, ftp and rcp.

What is SSH? What is SFTP?

SSH (Secure Shell Protocol) is a secure replacement for telnet. Like telnet, SSH can be used to connect to a remote host computer using an account name and password. The advantages of SSH over telnet are:

  1. All information transmitted between your computer and the host is encrypted. This protects your password during login as well as information transmitted after logging in.
  2. If available, you can use a publicly published 'fingerprint' for a host's 'key' to verify the host's identity.

Make a Connection to a Remote Host

  1. Open Terminal in the Applications > Utilities folder.
  2. Type ssh account_name@host_name in the terminal window, where account_name is your account name on the host and host_name is the host's full Internet name. Press the Return key. If you are connecting to apollo.sfsu.edu or libra.sfsu.edu then replace account_name with your SFSU email account name and replace host_name with either apollo.sfsu.edu or libra.sfsu.edu. For example, Jane Doe, with SFSU email account janedoe, would connect to host libra.sfsu.edu by typing:ssh janedoe@libra.sfsu.edu then pressing the Return key.
  3. The first time you connect to a host you will see a message similar to:

    The authenticity of host 'libra.sfsu.edu (130.212.10.238)' can't be established.
    RSA key fingerprint is 57:fe:4b:78:94:1e:8c:3d:28:ce:67:40:85:fe:24:85.
    Are you sure you want to continue connecting (yes/no)?

    • Verify the host matches one of the following:
      • online.sfsu.edu - updated 11/25/08
        • 06:4e:57:ee:f5:c8:e7:c7:99:9a:e9:5f:95:88:53:a1
          xunil-novip-mafuh-moduc-tunuk-dulyb-symen-hebim-tacec-kypiz-nyxax
      • www.sfsu.edu - updated 11/25/08
        • 73:c2:09:ec:f5:8a:a2:cf:d8:4e:34:bd:24:1f:b3:66
          xepop-cigab-vokyd-tipyh-vadaf-sidez-cunat-sylol-befug-sikyf-rixex
        • a4:bd:6f:3c:61:5b:15:7b:da:ef:7f:1c:27:2a:8a:b2
          xonob-likem-tunyg-semon-nogeb-bukag-hucos-zyzyg-mecih-zuvoh-lexix
      • If the fingerprints do NOT match, click the Cancel button to cancel your connection. Submit a Service Request. Mismatched fingerprints might mean that your connection has been compromised.
      • If the fingerprints DO match, type yes then press the Return key. You will see a message similar to:

        Warning: Permanently added 'libra.sfsu.edu,130.212.10.238' (RSA) to the list of known hosts.

  4. Type your password when prompted then press the Return key.
  5. Use the resulting SSH session the same way you would use a telnet session.
  6. When you are finished exit your SSH session, close your terminal window, then close Terminal.

What if the Fingerprints Matched Originally but They Don't Now?

Using the SSH client built in to Mac OS X you will you get a message similar to the following:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is 57:fe:4b:78:94:1e:8c:3d:28:ce:67:40:85:fe:24:85.
Please contact your system administrator.
Add correct host key in /Users/janedoe/.ssh/known_hosts to get rid of this message.
Offending key in /Users/janedoe/.ssh/known_hosts:1
RSA host key for libra.sfsu.edu has changed and you have requested strict checking.
Host key verification failed.

This either means that the host has a new key and the fingerprint has changed or that you are the victim of a man-in-the-middle exploit. In order to protect you, the Mac OS X SSH client will not let you complete the connection to this host until the old key is removed from your computer. If you determine that the host's key has been changed (see connection instructions for current keys), follow these steps to remove the old key:

  1. Open Terminal in the Applications > Utilities folder.
  2. Type open .ssh in the terminal window then press the Return key. This opens the .ssh folder which contains the file known_hosts.
  3. Drag known_hosts into the trash then close the .ssh folder.
  4. Close Terminal.

Deleting known_hosts removes all host keys from your computer so all hosts you connect to will be treated as though you are connecting to them for the first time.
