Annika, Borja, thank you for the suggestions. I'll consider purpose-building such host, but still hope to stumble upon existing one (some remote observatory on a satellite link probably…)
An example creating a 20 second delay. # ipfw pipe 10 config delay 9999 Now we create a couple of firewall rules. I will give this “royal treatment” to betweeen “pinger” and “pingee” # ipfw add 121 pipe 10 icmp from x.y.z.t to me # ipfw add 122 pipe 10 icmp from me to x.y.z.t (Adding delay to both the ping and the ping ack so that the maximum delay I can get is 20000 ms) And testing: 64 bytes from a.b.c.d: icmp_seq=259 ttl=60 time=20000.069 ms If you need it, give me the IP addresses from which you intend to do the tests and the delay you need and I can create a ping target on my test server in Amazon’s EC2. Cheers, Borja.
