SExec Component

Properties   Methods   Events   Configuration Settings   Errors  

The SExec component is used to remotely execute a command on an SSH server.

Syntax

nsoftware.IPWorksSSH.Sexec

Remarks

The SExec component establishes a Secure Shell (SSH) connection to a server and starts up the user's default shell. Using the component is very simple. The destination is specified by the SSHHost property, and the login information is given by the SSHUser and SSHPassword properties. To execute the command, simply call the Execute command or set the Command property with the command you wish to execute as the parameter. Further input can be supplied to the Text parameter of the Send method or via the Stdin property.

The output of the command is returned through the Stdout event. If an error happens on the protocol level, the error message can be found in the ErrorMessage property. Errors during command execution (the stderr stream) are given by the Stderr event. Once the remote command or application terminates, the component will disconnect from the server. If the application's exit status is non-zero (success), the component will throw an exception.
