From e17eb0d9eb2faf22e5383bf41061521e08b4a0e6 Mon Sep 17 00:00:00 2001 From: Eoin Brazil Date: Sun, 14 Dec 2014 16:04:26 +0000 Subject: [PATCH] Added ip_neigh - ip neigh check Interesting blog (http://engineering.clever.com/2014/12/10/when-your-ip-traffic-in-aws-disappears-into-a-black-hole/) pointed out that ARP tables in AWS can be cached and reflect stale MACs from non-current boxes. Added ip neigh check to highlight STALE or REACHABLE states. --- mdiag/mdiag.sh | 1 + 1 file changed, 1 insertion(+) diff --git a/mdiag/mdiag.sh b/mdiag/mdiag.sh index 7d1a8dfc..4df6cea5 100644 --- a/mdiag/mdiag.sh +++ b/mdiag/mdiag.sh @@ -226,6 +226,7 @@ msection ip_link ip link msection ip_addr ip addr msection ip_route ip route msection ip_rule ip rule +msection ip_neigh ip neigh msection hosts getfiles /etc/hosts msection host.conf getfiles /etc/host.conf msection resolv getfiles /etc/resolv.conf
