hello,
Here is a picture, of what I have: (I don't know how it will look for you, so you can also find it here (EDIT: or as an attachement)
linksys router |----------------------------------------- my computer with openvz -------------------------------------------------------------------------|
00:0f:66:83:45:8e | eth0 veth103.0 |--------------------------------------------------------------------||
10.3.0.13 -------------| 00:30:1B:B6:F2:1C 00:18:51:B4:A6:85 --------------- | eth0 VE: name=debnated(not yet nated actually)||
| 10.3.0.50 10.4.0.50 | 00:18:51:ce:18:98 ||
| | 10.4.0.52 ||
| ---------------------------------------------------------------------||
|-------------------------------------------------------------------------------------------------------------------------------------------|
on the VE "debnated" (ip: 10.4.0.52):
ping 10.3.0.13
one tcpdump process running on the eth0 and the other on veth103.0 : (after sorting them (and added the "== interface" at the end of the line), here is what I get)
1) 10:02:24.541939 00:18:51:ce:18:98 (oui Unknown) > Broadcast, ethertype ARP (0x0806), length 42: arp who-has 10.4.0.50 tell debnated == on veth103.0
2) 10:02:24.541968 00:18:51:b4:a6:85 (oui Unknown) > 00:18:51:ce:18:98 (oui Unknown), ethertype ARP (0x0806), length 42: arp reply 10.4.0.50 is-at 00:18:51:b4:a6:85 (oui Unknown) == on veth103.0
3) 10:02:24.541973 00:30:1b:b6:f2:1c (oui Unknown) > 00:0f:66:83:45:8e (oui Unknown), ethertype IPv4 (0x0800), length 98: debnated > linksys: ICMP echo request, id 56597, seq 1, length 64 == on veth103.0
4) 10:02:24.542005 00:30:1b:b6:f2:1c (oui Unknown) > 00:0f:66:83:45:8e (oui Unknown), ethertype IPv4 (0x0800), length 98: debnated > linksys: ICMP echo request, id 56597, seq 1, length 64 == on eth0
5) 10:02:24.542615 00:0f:66:83:45:8e (oui Unknown) > 00:30:1b:b6:f2:1c (oui Unknown), ethertype IPv4 (0x0800), length 98: linksys > debnated: ICMP echo reply, id 56597, seq 1, length 64 == on eth0
6) 10:02:24.542633 00:18:51:b4:a6:85 (oui Unknown) > 00:18:51:ce:18:98 (oui Unknown), ethertype IPv4 (0x0800), length 98: linksys > debnated: ICMP echo reply, id 56597, seq 1, length 64 == on veth103.0
7) 10:02:29.540780 00:18:51:b4:a6:85 (oui Unknown) > 00:18:51:ce:18:98 (oui Unknown), ethertype ARP (0x0806), length 42: arp who-has debnated tell 10.4.0.50 == on veth103.0
8) 10:02:29.540809 00:18:51:ce:18:98 (oui Unknown) > 00:18:51:b4:a6:85 (oui Unknown), ethertype ARP (0x0806), length 42: arp reply debnated is-at 00:18:51:ce:18:98 (oui Unknown) == on veth103.0
take the 3) line for example, look at the MAC address, shouldn't it be 00:18:51:ce:18:98 > 00:18:51:B4:A6:85 instead ? the VE "debnated" should not even know thess MAC address? (unless I misunderstood something)
here is the arp cache on 'debnated", just after the ping:
debnated:/ # arp
Address HWtype HWaddress Flags Mask Iface
10.4.0.50 ether 00:18:51:B4:A6:85 C eth0
I don't know if it's because of how openvz works, or if I made something wrong?
thanks in advance
