Can you please try to create an static an ARP entry for (.7) on (.5), ``` # arp -s 172.18.1.7 70:85:c2:c1:19:11 ``` and test the connection again ? Also the ARP entry on (.7) is helpful to diagnose. > Thus I believe I have observed the reply not getting to the destination (= .5) > machine. Now I have already looked at the switch involved and moved these= two to a > different switch. Same result. A better way to is connecting the two machines, (.5) and (.7), directly wit= h a crossover cable. Well a patch cable should also work, as Intel i350 ( and m= any NICs ) supports auto MDI-X. --=20 You are receiving this mail because: You are the assignee for the bug.=
