Hi.
Thank you for the answer.

I think I located the problem. Seems like it is our Firewall/Antivirus, that interferes with winpcap.

I suppose you see the same behavior with windump. Right?

 

Do you have any sort of

 

- personal firewall

- VPN software

- antivirus

- tunneling protocol

 

installed on the failing machines?

 

If windump causes the same behavior, can you please file a bug report as explained at

Have a nice day

Hi.
Thank you for answering.

Now I'm using the latest versions, just downloaded them, before I had Ethereal with winpcap 3.1. There is not any difference in their behaviour though.

There is one thing more to mention about TCP. Sessions opened before capturing stay open, for example SSH. Opening a new one during capturing is not possible.

Hi,
What version of Wireshark and WinPcap are you using?
Wiresark 0.99.5 and WinPcap 4.0 are the latest versions.
Best regards
Anders

Subject: [Wireshark-users] TCP capture problem,


Hi, I'm having problems with packet capturing. When I turn it on, no TCP-traffic gets through. Web browser, SSH-client and all the other applications using TCP just freeze. No such problems with UDP though, for example SIP-clients can register and make calls without any difficulties. I guess this could be a problem of Winpcap, but I do not have any idea how to fix it.

Does anyone else have this kind of trouble. There is at least 7 computers at my work with Win XP SP2, that has this problem.

Thank you in advance.
