Anyone know of a server that will delay icmp responses? I need a ping target that will echo reliably, but with a 1000-3000ms (or more) delay [migrated]

It’s weird to think anyone would need such a thing, but here I am. I’m testing a bunch of icmp tools and am having a hard time testing them without simply faking the responses and there are reasons that doing so might give me a false confi… Continue reading Anyone know of a server that will delay icmp responses?

Posted on by

We use an external scanner (Qualys) to scan our external assets. We have a firewall in front of the external assets, but it is configured to whitelist the scanner so that the external assets get scanned in-depth. But the firewall is also c… Continue reading ICMP timestamp – firewall configured to drop timestamp request, but vulnerability scanner can send request and get a response→
