Great idea Ed! It's been years since I worked on Ethernet drivers for IBM and forgot all about that command. Checking man it shows arp to be obsolete so I used ip: big4 /temp # ip -s neigh fe80::9afc:11ff:fe83:6dfe dev eth0 lladdr 98:fc:11:83:6d:fe router ref 1 used 1364540/1364600/1 STALE 192.168.1.111 dev eth0 ref 1 used 140/200/137 FAILED 192.168.1.1 dev eth0 lladdr 98:fc:11:83:6d:fe ref 31 used 71/11/44 REACHABLE As you can see laptop1 at 192.168.1.111 cannot be pinged by big4. Now I will ping big4 from laptop1: laptop1 ~ # ping -c 1 192.168.1.109 PING 192.168.1.109 (192.168.1.109) 56(84) bytes of data. 64 bytes from 192.168.1.109: icmp_seq=1 ttl=64 time=0.666 ms --- 192.168.1.109 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.666/0.666/0.666/0.000 ms Now running the ip command again from big4: big4 /temp # ip -s neigh fe80::9afc:11ff:fe83:6dfe dev eth0 lladdr 98:fc:11:83:6d:fe router ref 1 used 1364856/1364916/1 STALE 192.168.1.111 dev eth0 lladdr 00:23:4e:df:d1:5d ref 3 used 47/47/32 STALE 192.168.1.1 dev eth0 lladdr 98:fc:11:83:6d:fe ref 25 used 23/11/1 REACHABLE Of course the ping/ssh work now as well. Will look at new routers tomorrow.
