If nobody screams in a few days. 2.77 is go. I just realised that the anniversary of the release of 2.76 was couple of days ago. A year between releases in unprecedented.

Actually, its the sort-of opposite. loopback seems to respond to any address in 127.0.0.0/8 so you get a reply to an ICMP echo request from any 127.0.0.0/8 address, even if the loopback interface doesn't explicitly have that address srk@holly:~/dnsmasq/dnsmasq$ ifconfig lo loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:2194 errors:0 dropped:0 overruns:0 frame:0 TX packets:2194 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:164612 (164.6 KB) TX bytes:164612 (164.6 KB) srk@holly:~/dnsmasq/dnsmasq$ ping 127.0.0.2 PING 127.0.0.2 (127.0.0.2) 56(84) bytes of data. 64 bytes from 127.0.0.2: icmp_seq=1 ttl=64 time=0.068 ms 64 bytes from 127.0.0.2: icmp_seq=2 ttl=64 time=0.065 ms ^C --- 127.0.0.2 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms I'll patch it to suppress ping-checks for the loopback interface.

Yes. I'll look at putting code to suppress the ARP check. on loopback. Cheers, Simon.

I wonder if this is to do with the extension of the ping-test to more cases. Please could you try adding no-ping to the config, and see if that improves things? Cheers, Simon.
