Preferred Version
Select an SSH protocol version to use. SSH2 is recommended since it provides stronger security and more functionalities than SSH1.

Port Number
Enter port number to use in the SSH connection.

Use Default
Set [Port Number] as 22, the SSH protocol default port.

Send keep alive signal
Send a keep alive signal to the remote host. This function is used to prevent disconnection while a user is temporarily absent. In some network environments, a gateway or a firewall system may terminate connections without notice when the connection is idle for a specified period of time.

Method
Select the method to use for user authentication. Support SSH authentication methods include Password, Public Key, Keyboard interactive, GSSAPI, and PKCS#11. If using the GSSAPI or PKCS#11 methods, click the [Setup] button and enter the required information.

User Key
If the Public Key method has been selected, the user can specify which user key to use. Click [Browse] to select the user key. Users can also create, modify, delete, import, and export user keys from the User Key dialog box. For more information regarding Public Keys and user key management, please see "Public Key User Authentication"and "User Keys Dialog Box".

Passphrase
If the Public Key method has been selected, the user key's passphrase should be entered here. The passphrase of the user key can be changed in the User Key dialog box.

Use SSH authentication agent (Xagent)
If opting to use Xagent, Public Key authentication is attempted initially.
Xagent is an SSH authentication agent. Xagent holds user keys that are used for public key authentication and passes the key to the SSH client when required.
Xagent maintains a list of all SSH client user keys, and if required, prompts the user for a key passphrase. Once the correct key passphrase in inputted, Xagent unencrypts the key and it is stored in memory. Therefore, with Xagent, users can enter a passphrase once and use the key multiple times.
