Remarks

This event is fired whenever a host attempts to open a new channel. ChannelId will contain the id of the channel to be created. Service will identify the type of channel that is being requested (e.g.: "session"). Set Accept to true to accept the channel open request.

If the channel open request contains extra information, it will be contained in Parameters; you can extract data from it using GetSSHParam and GetSSHParamBytes. The most common example of a request with parameters would be a request with Service set to "direct-tcpip" (for SSH tunneling); in that case Parameters will contain the host to connect (string), the port to connect (int), the originator IP address (string) and the originator TCP port (int).
