MrHappy Posted July 29, 2017 Share Posted July 29, 2017 I was bored the other day & was messing at work, using Wireshark I can see everything on my network sending packets of data (whatever) as expected. Our alarm signals via a TCD,oddly I can't see any data connected to its IP ? I can see data when I ping..... Being just a simple alarm monkey... can anyone explains whats happening ?

james.wilson Posted July 29, 2017 Share Posted July 29, 2017 is the signalling using udp or tcp? Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount. Link to comment Share on other sites More sharing options...
petrolhead Posted July 29, 2017 Share Posted July 29, 2017 You wont see all traffic on the network unless you are using an ancient hub or a managed switch with port mirroring, some traffic will be invisible to the machine running wireshark, most of the traffic you see will be broadcast traffic.
