Message-ID: <0a8e33b5f18b75d5b68a543259e8a0ad@coraid.com> (raw)
has anyone seen snoopy miss packets like this? i see the ack for a packet
that snoopy never sees. these hosts are connected back-to-back.
Δt between the two snoopies is ~45000 ms.
target host:
[... lots of packets deleted, none with a sequence of 3276011294 ...]
046689 ms
ether(s=0060dd4785fb d=0060dd47b40c pr=0800 ln=60)
ip(s=192.168.0.3 d=192.168.0.1 id=5751 frag=0000 ttl=255 pr=6 ln=40)
tcp(s=6666 d=5123 seq=2082542180 ack=3276011294 fl=AP win=36700 ck=2826)
[... no packet with seq=3276011294 from 192.168.0.1 follows]
but the source host did actually send the packet:
001112 ms
ether(s=0060dd47b40c d=0060dd4785fb pr=0800 ln=854)
ip(s=192.168.0.1 d=192.168.0.3 id=646c frag=0000 ttl=255 pr=6 ln=840)
tcp(s=5123 d=6666 seq=3276011294 ack=2082542180 fl=A win=65535 ck=b46a)
dump(0000000000000000000000000000000000000000000000000000000000000000)
