Demonstrates how to establish an SSH session with a Sophos XG router and send commands in a device console session. Visual FoxPro

LOCAL lnSuccess
LOCAL loSsh
LOCAL lnChannelNum

lnSuccess = 0

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

loSsh = CreateObject('Chilkat.Ssh')

lnSuccess = loSsh.Connect("172.16.16.16",22)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

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

* Start a shell session.
* (The QuickShell method was added in Chilkat v9.5.0.65)
lnChannelNum = loSsh.QuickShell()
IF (lnChannelNum < 0) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* The Sophos router will send this initial prompt:

* 	Main Menu
* 
* 	    1.  Network  Configuration
* 	    2.  System   Configuration
* 	    3.  Route    Configuration
* 	    4.  Device Console
* 	    5.  Device Management
* 	    6.  VPN Management
* 	    7.  Shutdown/Reboot Device
* 	    0.  Exit
* 
* 	    Select Menu Number [0-7]: 

lnSuccess = loSsh.ChannelReceiveUntilMatch(lnChannelNum,"Select Menu Number","utf-8",1)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Show what we received so far:
? loSsh.GetReceivedText(lnChannelNum,"utf-8")

* Send "4" <RETURN> to mimic typing in a shell session.
lnSuccess = loSsh.ChannelSendString(lnChannelNum,"4" + CHR(10),"utf-8")
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* We should get a "console>" prompt.
lnSuccess = loSsh.ChannelReceiveUntilMatch(lnChannelNum,"console>","utf-8",1)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

? loSsh.GetReceivedText(lnChannelNum,"utf-8")

* Send a command and get the output..
lnSuccess = loSsh.ChannelSendString(lnChannelNum,"dnslookup host google.com" + CHR(10),"utf-8")
lnSuccess = loSsh.ChannelReceiveUntilMatch(lnChannelNum,"console>","utf-8",1)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

? loSsh.GetReceivedText(lnChannelNum,"utf-8")

* Send another command and get the output, and so on...
lnSuccess = loSsh.ChannelSendString(lnChannelNum,"dnslookup host microsoft.com" + CHR(10),"utf-8")
lnSuccess = loSsh.ChannelReceiveUntilMatch(lnChannelNum,"console>","utf-8",1)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

? loSsh.GetReceivedText(lnChannelNum,"utf-8")

loSsh.Disconnect()

RELEASE loSsh
