check if device service available

Hi,

Is there a way to check if a specific service or port (for example port 80) is available?

Regards,

José Chaves

Here is the link which can show you all the ports that you are looking for, i belive port 80 is there already:

I think, he will do a active check for a range of devices.

I think you can do this with the governance / compliance engine of XMC

Hello Jose,

there is no built-in function to check any devices in the network for open ports.
But you can easily build this with a script or workflow. Below is a small example. The script is direct executable in XMC. If you want to generate alarms/emails etc. depending on the result, you can do that with the alarms.

import subprocess

out = subprocess.Popen(['nc', '-zv', '-w 10', '10.10.10.10', '80'], 
           stdout=subprocess.PIPE, 
           stderr=subprocess.STDOUT)

stdout = out.communicate()
print(stdout)

if stdout.find('succeeded!') != -1:
    print ("Port is open")
elif stdout.find('timed out:') != -1:
    print ("Device not reachable")
else:
    print ("Port is not open")
