Wireshark shows duplicates of each Uplink frame (but not DL)

Sending TCP DL (iperf) traffic from a network server to an IBM Thinkpad running wireshark 1.8.6.

DL traffic looks normal, but each UL packet (whether Syn or ACK) sourced from the laptop pc appears twice in wireshark (same TCP sequence number and same IP ID), but typically 20-30 microseconds difference in time stamps.

The tester is remote, so I haven't been able to physically inspect his computer, but I do not see this on any other computers.

For viewing, I can filter out the replications using a filter, such as "&& not tcp.analysis.duplicate_ack" but am curious what may be causing each UL packet to appear twice?

I don't think the user has wireshark monitoring two different interfaces, or he would also see duplicates in the downlink packets.

I could not attach a wireshark trace, but created a text view of the first few packets, shown below.
frame 1 - SYN (sent from laptop toward network server) frame 2 = duplicate of frame 1 frame 3 = SYN ACK (received from network server) frame 4 = ACK to frame 3 frame 5 = duplicate of frame 4 and so on... each time, any frame sent by the UE appears in duplication in the wireshark trace, although each UE packet is actually sent only once (as confirmed by traces captured on the network server).

can you please post the capture file on google docs, dropbox or cloudshark.org?

(20 Mar '13, 09:19) Kurt Knochner ♦

Hi, Please confirm if you're able to access this in Google Docs. https://docs.google.com/file/d/0BzI9HmeXKHvPdV9rNkgwVEF4Yk0/edit?usp=sharing Thanks! Fred

I can't access the file. I'm getting asked for a google account. Can you please share the file publicly?

(20 Mar '13, 11:14) Kurt Knochner ♦

Sorry... I don't normally use google docs...

I found an option to share the file with anyone that has the link. Hopefully, you will not need a google account this time?

I can download it now. However, there is nothing in the capture file that might explain the effect. Did you check the "interfering software" (see my answer below)?

(20 Mar '13, 13:28) Kurt Knochner ♦

One Answer:

Please check if there is any interfering software installed on that laptop (AV, IPS, Firewalls, Endpoint Security, VPN Clients, etc.). If so, please disable it and redo the test.

Regards
Kurt

Hi, Kurt. Thanks for looking. No... I have not been able to check the pc. The tester with the pc is 2000 miles away, and presently tied up troubleshooting an issue. (We can work around this wireshark display issue for now, since I know the pc is not actually sending duplicates of each packet.) When the tester is available, I will ask him to temporarily disable all other such applications to see if that resolves the issue. Fred
