I'm seeing something similar to bug 1179 (https://bugzilla.mindrot.org/show_bug.cgi?id=1179), even with the reordered IP options check. For some reason, getsockopt is returning an IP options of length 2, value 00 00. Would Mark Weindling's original patch (https://bugzilla.mindrot.org/attachment.cgi?id=1105) break anything if I incorporated it? Platform: HP NonStop S7000 series

I was wondering what everyone's thoughts were on a simpler way to exclude addresses from having listeners on them. I know a lot of people have multiple subnets, especially larger corporations. Some networks are non-route-able, and therefor unsuitable for use with SSH, aside from communication between other servers on the same subnet. Given that we may want to exclude those non-route-able

...(4, TCGETS, 0x08046F64) Err#25 ENOTTY Which makes me think this is canohost.c:get_remote_hostname(). It does a getpeername() call that is probably the xgetscoaddr call above. It then does a: if (getnameinfo((struct sockaddr *)&from, fromlen, ntop, sizeof(ntop), NULL, 0, NI_NUMERICHOST) != 0) call. This should not result in any DNS traffic though - it's requesting a numeric hostname. IMO the only way for it to end up in the DNS here is if the OS getnameinfo() is buggy. This is further supported by what it does next: 20538: open("/etc/services", O_RDONLY, 0666)...
