SSH Commands to Sophos Router Device Console

See more SSH Examples

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

require 'chilkat'

success = false

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

# Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Start a shell session.
# (The QuickShell method was added in Chilkat v9.5.0.65)

# 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]:
