* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loSsh = CreateObject('Chilkat.Ssh')

* Connect to an SSH server:

* Hostname may be an IP address or hostname:
lcHostname = "192.168.1.108"
lnPort = 22

lnSuccess = loSsh.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Wait a max of 5 seconds when reading responses..
loSsh.IdleTimeoutMs = 5000

* Authenticate using login/password:
lnSuccess = loSsh.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Open a session channel.  (It is possible to have multiple
* session channels open simultaneously.)

lnChannelNum = loSsh.OpenSessionChannel()
IF (lnChannelNum < 0) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* 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:
lcCmd1 = "dir"

* Do a nameserver lookup:
lcCmd2 = "nslookup chilkatsoft.com"

* List a specific directory.  Given that the shell is CMD.EXE, backslashes must
* be used:
lcCmd3 = "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:
lcCmd4 = '"cd \temp&&dir"'

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

* Get a directory listing:
lcCmd5 = "ls -l /tmp"

* Run a series of commands (syntax may depend on your default shell):
lcCmd6 = "cd /etc; ls -la"

* Request a directory listing on the remote server:
* If your server is Windows, change the string from "ls" to "dir"
lnSuccess = loSsh.SendReqExec(lnChannelNum,"ls")
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Call ChannelReceiveToClose to read 
* output until the server's corresponding "channel close" is received.
lnSuccess = loSsh.ChannelReceiveToClose(lnChannelNum)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Let's pickup the accumulated output of the command:
lcCmdOutput = loSsh.GetReceivedText(lnChannelNum,"ansi")
IF (loSsh.LastMethodSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Display the remote shell's command output:
? lcCmdOutput

* Disconnect
loSsh.Disconnect()

RELEASE loSsh
