PortBindRequest event

Fires when user wants to bind specific port on the server.


  • Basic
Private Sub object_PortBindRequest(User, BindIP, BindPort, Action)  
The PortBindRequest(object,User,BindIP,BindPort,Action) syntax has these parts:
objectA wodSSHD object.
UserA SSHUser object.
BindIPA String value. Holds interface address that will be used for listening.
BindPortA Long value. Specifies port number that will be used for listening.
ActionA SSHActions enumeration, as described in settings. Action to perform for the user - Allow means that he can open port forwarding, Deny means he is not allowed.


The settings for Action are:

Constant Value Description
Deny0 Deny execution of the action.
Allow 1 Allow to execute action.

This event is fired 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, event PortForwardConnect will be fired where you can see 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, event PortForwardRequest will be fired.
