But I am able to ping it from the command line. I let the ping run for over 30 minutes and not a single packet was lost. I tried fping and the "normal" ping that came with my Redhat 9. I also tried larger icmp packets which worked too: $ fping -b 1500 -c 5 10.60.2.20 10.60.2.20 : [0], 1528 bytes, 121 ms (121 avg, 0% loss) 10.60.2.20 : [1], 1528 bytes, 120 ms (121 avg, 0% loss) 10.60.2.20 : [2], 1528 bytes, 121 ms (121 avg, 0% loss) 10.60.2.20 : [3], 1528 bytes, 120 ms (121 avg, 0% loss) 10.60.2.20 : [4], 1528 bytes, 142 ms (125 avg, 0% loss) 10.60.2.20 : xmt/rcv/%loss = 5/5/0%, min/avg/max = 120/125/142 Is smokeping using any special flags for fping that might create icmp packets that are dropped by the firewall in front of <<suspicious_host>> ?
