I'm trying to use System.isHostReachable(IP) in a vCO workflow but ALL the IPs returns true, Do I need to configure something in order to get this working?
Nothing need to be configured. This method simply calls the underlying Java API InetAddress#isReachable()
Could you try to ping the IPs from the shell console?
Yeah, from SSH is working correctly but not when using System.isHostReachable in vCO.
Also I used a java class with InetAddress#isReachable() and execute it from the command line and it worked fine.
