All the four ARP requests from the Ubuntu server come to the remote router (non Ubuntu) and can be seen in its log:
00:0a:5e:01:01:11 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 64: vlan 321, p 0, ethertype 802.1Q, vlan 6, p 6, ethertype ARP, arp who-has 10.150.243.38 tell 10.150.243.37 00:0a:5e:01:01:11 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 64: vlan 321, p 0, ethertype 802.1Q, vlan 6, p 6, ethertype ARP, arp who-has 10.150.243.38 tell 10.150.243.37 28:8a:1c:64:1b:3e > 00:0a:5e:01:01:11, ethertype 802.1Q (0x8100), length 46: vlan 6, p 6, ethertype ARP, arp reply 10.150.243.38 is-at 28:8a:1c:64:1b:3e 28:8a:1c:64:1b:3e > 00:0a:5e:01:01:11, ethertype 802.1Q (0x8100), length 46: vlan 6, p 6, ethertype ARP, arp reply 10.150.243.38 is-at 28:8a:1c:64:1b:3e 00:0a:5e:01:01:11 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 64: vlan 321, p 0, ethertype 802.1Q, vlan 6, p 6, ethertype ARP, arp who-has 10.150.243.38 tell 10.150.243.37 28:8a:1c:64:1b:3e > 00:0a:5e:01:01:11, ethertype 802.1Q (0x8100), length 46: vlan 6, p 6, ethertype ARP, arp reply 10.150.243.38 is-at 28:8a:1c:64:1b:3e 00:0a:5e:01:01:11 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 64: vlan 321, p 0, ethertype 802.1Q, vlan 6, p 6, ethertype ARP, arp who-has 10.150.243.38 tell 10.150.243.37 28:8a:1c:64:1b:3e > 00:0a:5e:01:01:11, ethertype 802.1Q (0x8100), length 46: vlan 6, p 6, ethertype ARP, arp reply 10.150.243.38 is-at 28:8a:1c:64:1b:3e So, 4 ARP requests were received from the Ubuntu server and accordingly 4 ARP replies were sent by the router to the Ubuntu server. However, only 3 of 4 ARP requests (Ubuntu -> Router) are recorded each time by tcpdump in a trace file on the Ubuntu server. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828392 Title: Oubound packets sent into the line are not all captured by tcpdump To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tcpdump/+bug/1828392/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
