The /etc/ssh/sshd_config file has an entry called AuthenticationMethods. Typically you would enter either: to indicate which authentication method should be required. You can also enter: to indicate that either authentication method should be required. You can also enter: to indicate that both authentication methods should be required. If a server requires both publickey and password, then call AuthenticatePwPk. If a […]
Before Chilkat’s SSH Tunnel, your app would need to connect to a tunnel process/service running either on the local machine or on some computer on the LAN, and then tunnel out to the remote server. It would look like this: App ——(1)——> TunnelService —-(2)——> SshServer —-(3)—–> SomeDestServerSuchAsSQL You can wrap a non-encrypted TCP connection, or a TLS connection within the […]
The Chilkat SshTunnel object/class (may be “CkSshTunnel” in some programming languages) provides a number of properties to help in debugging (i.e. understanding) what is happening in the background thread: AcceptThreadSessionLogPath: May be set to the path of a log file that the SshTunnel will create and log activity regarding connections accepted. This will allow you to see incoming connections that […]
SSH Port Forwarding (or tunneling) allows you to tunnel any TCP connection through an SSH server. For example, consider a database connection: A direct TCP connection: DbClient <—-TCP—-> DbServer An SSH tunneled connection: DbClient <—-TCP—-> SshClient <====SSH====> SshServer <—-TCP—-> DbServer In a tunneled connection, the application connects through an SshClient to an SSH server and starts a direct-tcpip channel, specifying […]
