Connection

The protocol settings used in the connection are configured using the Connection page of the Settings dialog. Any changed connection settings will take effect the next time you login.

Figure : The Connection page of the Settings dialog.

• Host Name

  Type the name of the remote host computer which you will connect to using this profile. If you specify * (an asterisk) as the host name, you will be prompted to type in the host name when connecting.

• User Name

  Type the user name you want to use when connecting to the remote host computer. If you specify * (an asterisk) as the user name, you will be prompted to type in the user name when connecting.

• Port Number

  Type the port number you want to use for the SSH2 connection. The default port is 22.

  Note: that an sshd2 daemon program must be listening on the specified port on the remote host computer or the connection attempt will not succeed. If you are unsure of which port the remote host computer is listening to, contact the system administrator of the remote host.

• Encryption Algorithm

  Select the desired encryption algorithm from the dropdown menu. Valid choices are 3DES, Blowfish, Twofish, AES, Arcfour, and CAST. Also DES is supported for compatibility reasons, however it is no longer considered cryptographically secure. You can also select whatever default that is used by the remote host computer, use no enryption (none) at all, or create your own cipher list. For more information on the Cipher List option, see section Cipher List.

  For the AES and Twofish algorithms you can also choose the strength of encryption, ie. how many bits will be used. Greater values are more secure, but slower to use. Possible values are 128, 192 or 256 bits.

  Note: If you select none as the encryption algorithm, the communications for this profile will not be encrypted and all information will be sent as plaintext. The none encryption method is not secure and its use is not recommended. Use it only for testing purposes! If you select this option, a warning dialog will be displayed.

• MAC Algorithm

  Select the desired Message Authentication Code (MAC) algorithm (hash algorithm) from the dropdown menu. Valid choices are HMAC-MD5 and HMAC-SHA1. You can also select whatever default that is used by the remote host computer, or select to use no message authentication code at all (none). If you select not to use any MAC algorithm, a confirmation dialog will be displayed.

• Compression

  Select the desired compression setting from the dropdown menu. Valid choices are zlib and none. Compression is disabled by default.

• Terminal Answerback

  Select the desired terminal answerback from the dropdown menu. Possible choices are ansi, vt100, vt102, vt220, vt320 and xterm.

• Connect through Firewall

  Select the checkbox if you are connecting through a firewall. For more information on the firewall settings, see section Firewall.

• Request Tunnels Only (Disable Terminal)

  Select the Request Tunnels Only checkbox if you wish to only set up the specified tunnels and not request a terminal or file transfer session.
