' The SendReqExec method starts a command on the remote
' server.   The syntax of the command string depends on the
' default shell used on the remote server to run the command.
' On Windows systems it is CMD.EXE.  On UNIX/Linux
' systems the user's default shell is typically defined in /etc/password.

' Here are some examples of command lines for <b>Windows SSH servers</b>:

' Get a directory listing:
cmd1 = "dir"

' Do a nameserver lookup:
cmd2 = "nslookup chilkatsoft.com"

' List a specific directory.  Given that the shell is CMD.EXE, backslashes must
' be used:
cmd3 = "dir \temp"

' Execute a sequence of commands.  The syntax for CMD.EXE may be found
' here: http://technet.microsoft.com/en-us/library/bb490880.aspx.  Notice how the commands
' are separated by "&&" and the entire command must be enclosed in quotes:
cmd4 = """cd \temp&&dir"""

' Here are two examples of command lines for <b>Linux/UNIX SSH servers</b>:

' Get a directory listing:
cmd5 = "ls -l /tmp"

' Run a series of commands (syntax may depend on your default shell):
cmd6 = "cd /etc; ls -la"

' Request a directory listing on the remote server:
' If your server is Windows, change the string from "ls" to "dir"
success = ssh.SendReqExec(channelNum,"ls")
If (success <> 1) Then

' Call ChannelReceiveToClose to read 
' output until the server's corresponding "channel close" is received.
