@ccwtech said in Ping... Is a 2 or 4 ms return on ethernet significant?:

That's their main switch. No other switches to bypass.

The point was ping something besides the server.

The server has all kinds of reason to provide bad responses.

If nothing else pings with odd response times, it means it is the server.

@tiagom said in Simple but Effective Packet Loss Monitor?:

To install one of the larger monitoring packages just for some simple packet loss monitoring seems like overkill. Especially since its like 10 lines to script this.

Everything is either a little more, or a little less, than I want. But this might suffice. Thanks.

@Jason They can't connect to the domain network, they're force onto the guest network. As we required any devices that want to join the domain network, they must already be in the domain.

Additionally, they need to authenticate via RADIUS.

The guest network is vlan'd off.
