Specifically, it allows you to start an ssh-agent, generate identities, and add identities to an agent. Nov 07, 2016 This assumes the remote server has ssh active, and if you’re able to ssh into the machine then it will have likely have scp active as well. If you don’t have a remote server to try this with, you can try it out between Mac OS X machines or with localhost if. Jan 06, 2020 PuTTY is the most popular SSH Connection Clients, however, it is a very basic SSH Client. Alternative 2020 Article 10 XAMPP Alternatives – Install WordPress On Windows And macOS Laptop. If you are searching for SSH with more features, here are some of the best and free SSH Clients for both Apple macOS and Microsoft Windows. Download away! Using the built-in SSH client in Mac OS X. Mac OS X includes a command-line SSH client as part of the operating system. To use it, goto Finder, and selext Go - Utilities from the top menu. Then look for Terminal. Terminal can be used to get a local terminal window, and also supports SSH connections to remote servers.
Mac OS X/macOS has a built-in SSH client called Terminal, and a popular SFTP client called Fetch is available to the UIC community.
By default, the Terminal.app is located in Applications > Utilities folder. Double-click on the icon to start the client.
Using Terminal for SSH
At the prompt type:
ssh NetID@hostnameGraphical Ssh Client Mac
where NetID is your UIC NetID and hostname is the hostname of the server you are trying to connect to. For example, if user example1 wants to connect to tigger.uic.edu, she would type:
ssh example1@tigger.uic.eduTo save a remote connection (so that you don't have to type in the command every time):
- Select Shell then New Remote Connection.. from the top menu
- Under the Server column, click on the + icon to add a new connection.
- Enter the hostname when prompted by the dialog.
- Enter your username (usually UIC NetID) in the User field and click Connect.
Using Fetch for Secure FTP
Fetch is a popular SFTP application that is compatible with Mac OS X 10.5 or later.
Installing Fetch
- Fetch is available for free download from the Webstore.
- Save the .dmg file to an easily accessible location, like your desktop
- Double-click on the .dmg file.
- Drag the Fetch.app dog into your Applications folder.
- Then a dialog box will open asking whether you want to install the Fetch Dashboard widget. Click Not Now or Install Widget.
- Click OK when the Dashboard widget is installed.
Using Fetch
- Double-click on the Fetch dog icon in your Applications folder.
- The connection dialog box opens. Fill in the Hostname:, Username:, and Password: boxes with the name of the machine you're connecting to, your login ID on that machine, and your password on that machine.
In the figure, example1 is logging into tigger.uic.edu and her NetID is example1.
The Password: is her ACCC common password.
Select SFTP from the dropdown list, and click Connect. - If this is a connection that you will want to use again, click the heart icon at the end of the Hostname: line before you click Connect, and click Make Shortcut in the small dialog box that opens. This opens another dialog box where you enter the name for the shortcut. The default name for the shortcut will be the host name. If you also click Make this the default shortcut, it will be opened by default for you when you open Fetch. Click OK to create the shortcut. The shortcuts are listed in Fetch's other screen, Fetch Shortcuts, which is at the top left of your desktop, where you can delete or edit them. You can use them from the heart dialog box.
- Then example1's home directory on tigger will be displayed in Fetch's screen:
- You can highlight a file and click Get to download it, or click Put to open up a Mac file dialog box to select a file to upload. But it's easier to double-click on the name of a directory that you want to open, double-click the name of a file that you want download, and drag and drop a file from your Mac to the Fetch screen to upload it or vice versa.
- To change a file on the server's permissions or to delete it, Control-click on its name, and select Get Info or Delete item respectively. To change the permissions, click in the type of permissions you want to give and click Apply.

ZOC SSH Features in Detail
ZOC is based on OpenSSH and supports the latest key exchange and encryption methods that the SSH protocol (RFC 4253) has to offer.
Free Ssh Client For Mac
Unlike OpenSSH, this ssh client is wrapped in a modern tabbed user interface with a powerful host directory, industrial strength emulations and scripting.
Below is an overview and explanation of some core SSH features of ZOC Terminal. We also have a whitepaper offering a more technical description of SSH.
Key Exchange
An especially difficult part of encrypted communication is the need to negotiate a shared secret (the key to use for encryption) over a public channel that could already be compromised.

The negotiation is performed through the so called Diffie-Hellman exchange or one of its many variants. ZOC supports all official diffie-hellman group exchanges, as well as the more modern ecdsa-sha2 and curve25519-sha256 protocols.
Authentication
Authenticating describes the process, where the user presents proof of who he is and the server deciding, if the user should be allowed access. The SSH protocol describes various methods that can be used for authentication.
Of those, ZOC supports password authentication, pukey exchange and keyboard-interactive challenge. Public-key exchange comes in various flavors. ZOC understands RSA, DSA, ECDSA and ED25519 keys. It is also possible to use hardware based key authentication (e.g. smart cards).
Encryption
Over time, the SSH protocol has seen a plethora of methods to be used to encrypt the communication (using shared secret was negotiated during the KEX phase as a cryptograhpic key). Some ciphers were phased out over time, especially after Edward Snowden revealed how powerful possible listeners like the NSA are, and new ones were introduced. ZOC supports the whole list, starting with aes256-ctr and going down to older ciphers like aes256-cbc or arcfour (these older ones may still be necessary to connect to older servers which have not been updated in a while).
Static Port-Forwarding
An important part of the secure shell protocol is a feature called port-forwarding. This feature allows the user to create a connection from the client computer to the server network, which can be used by other programs and where all the connection data is encrypted. This feature is sometimes called tunneling.
Dynamic Port-Forwarding
The standard port-forwarding feature requires the client to set up the tunnel source port and destination before making the connection. This means that there is limited flexibility and that for each possible destination, a separate ssh tunnel needs to be set up. With dynamic port forwarding however, the client sets up a listening port, but when a software connects to the port, it can select host and port it wants to connect to. The ssh client will then forward the connection request to the SSH server which initiates the connection to the final destination.
SSH Connection via Proxy
In some environments, end user computers are not allowed to access the outside internet directly. In those cases, connection and data exchange is made by way of a ssh proxy which handles the actual connection to the outside network (internet). There are various type of proxies, which mainly differ in how the ssh client requests a connection to the outside world. Most common types are SOCKS-4, SOCKS-5 and HTTP. ZOC supports connections through those types, as well as connections made through ssh-jumpservers.
SSH Agent Forwarding
When a user authenticates an SSH session using a public/private key pair, ZOC supports the SSH agent forwarding technique to provide the key for authentication in secondary ssh sessions (ssh connections to a third server, made from typing a ssh command in the remote shell in the initial connection). If all the servers allow authetication through this specific ssh key pair, it is not necessary to provide the passphrase again for secondary ssh connections.
X11 Forwarding
X11 is a communication protocol which allows a remote computer to run programs with a graphical user interface on a remote computer (normally, the server can show text only through a terminal client). SSH supports a way to tunnel this type of communication between ssh client and server, thus enabling the user to run an X11 command like xeyes on the remote shell and get the window for that displayed on the local computer.
