Wireshark · Wireshark-users: Re: [Wireshark-users] wireshark dropping packets? wireshark for xandros?

[Condor Kim <toothache200873@xxxxxxxxx>]

Hi,

 

apparently even though my wireshark is 1.x, it doesn't have this thing called status bar on it anywhere. i would wish i knew how to enable it.

 

i now have a even bigger problem. couple of days ago i was downloading a large software package from microsoft, and that day when i tried to save all the packets with my wireshark, suddenly this time my wirshark worked so slowly that it took more than 30 minutes to save a pcap file of 479 MB, whereas normally it will take 2 minutes. i knew my wireshark is coming to the end of its life. sure enough, today when i surfed on the net for merely 3 minutes, the wireshark kept flashing on the screen, and the packet display kept jumping, as if in a webcam, and none of the GUI buttons worked, so that i couldn't even save the file by clicking "file" and "save". has anyone encountered this problem?

 

i think it might be because there are several serious trojan horses active in my computer.

 

is there a way to use a command line to save the packets that have already been captured? i couldn't find the command on the help.chm.

Might those pages be cached by your browser?

Is this Windows? Does Windows have TOE (TCP Offload Engine) enabled? eg
Broadcom Netxtreme drivers support TOE.

If it does have TOE, depending on how many concurrent TCP sessions are
open you may see none, some, or all of the traffic for individual sessions.

And it was alledged to me yesterday that TOE is known to lose packets.
