Overview of Connection
Protocols
SecureCRT supports the following protocols: SSH1, SSH2, Telnet, serial, Local Shell, and Raw.
If you are using SecureCRT to connect to a BBS or any other type of terminal server by directly dialing the remote machine using your computer's modem, you will need to use the serial protocol.
If you are using SecureCRT to connect to a remote machine via the Internet or your LAN, you should use the SSH1 , SSH2 , Telnet protocol depending on the services provided by the remote machine to which you are connecting.
If you are using SecureCRT to establish a secure connection using encryption , you will need to use either the SSH1 or SSH2 protocol.
When the Raw protocol is used, little or no interpretation of the remote data takes place, which can be helpful for troubleshooting.
This following topics provide an explanation of the settings related to each of the protocols supported in SecureCRT:
Note: Only the protocols selected during the installation process will be available.
