Hi RIPE NCC, hi all, In today's troubleshooting adventure, an operator experienced difficulty pinpointing where exactly a connectivity issue between them and rpki.ripe.net (193.0.6.138 + 2001:67c:2e8:22::c100:68a) resided. It would be helpful if RIPE NCC reverted disabling responding to ICMP echo requests originating from the Internet. Would it be possible to adjust the firewall settings to accomodate troubleshooting and monitoring? Right now connectivity testing has to be performed directly against the rsync daemon's internet-exposed TCP port (873) - but it would be much cheaper and faster for both the tester and the service hoster if instead ICMP echo requests could be used as an early warning system (rather than the rsync service itself). $ ping -c 6 rpki.ripe.net PING rpki.ripe.net (193.0.6.138): 56 data bytes --- rpki.ripe.net ping statistics --- 6 packets transmitted, 0 packets received, 100.0% packet loss The above test result differs compared to sending echo requests to molamola.ripe.net or manus.authdns.ripe.net. Kind regards, Job
