PortBindRequest method
Called when user wants to bind specific port on the server.
Type
NoneSyntax
object.PortBindRequest Owner, User, BindIP, BindPort, Action
The PortBindRequest(object,Owner,User,BindIP,BindPort,Action) syntax has these parts:
| object | An expression evaluating to an object of type IwodSSHDNotify. |
| Owner | A wodSSHDcom object. Instance of wodSSHServer that called this notification method. |
| User | A SSHUser object. Reference to user who wants to bind a port. |
| BindIP | A String value. Holds interface address that will be used for listening. |
| BindPort | A Long value. Specifies port number that will be used for listening. |
| Action | A SSHActions enumeration, as described in settings. Return variable you should set to Allow or Deny, depending if you will allow or deny access for the user. |
Remarks
The settings for Action are:
| Constant | Value | Description |
| Deny | 0 | Deny execution of the action. |
| Allow | 1 | Allow to execute action. |
This method is called only if you implemented IwodSSHNotify interface in your application, and wodSSHD.Notification property has received reference to instance of your implementation.
This notification method is called when connected user requests service from wodSSHD to open specified port (
BindPort value) for listening. If you set
Action to
Allow, wodSSHD will open this port and listen for incoming connections, if possible. When connection arrives, notification method
PortForwardConnect will be called where you can see the Hostname of user who's trying to use this opened port. If all is Allowed, remote client will receive message about this connection, and it will be able to receive forwarded data for this connection.
Bind requests are typically used to protect plain communication from 3rd party sniffing (eavesdropping). For example, instead of opening local port on his computer, client can request server to open port. Complete traffic between wodSSHD server and the client will be encrypted (it's traveling through already established SSH connection).
If wodSSHD should initiate outgoing connection, notification method
PortForwardRequest will be called.
