The capture file appears to have been cut short in the middle of a packet - how to prevent this error?

问题

in my application i am open Tshark process and start capturing, when i want to finish to capturing i am kill the Tshark process so sometimes the capture file is corrupted and when i am trying to open this file i received the error the capture file appears to have been cut short in the middle of a packet - how to prevent this error there is a batter way to close the Tshark process to avoid this error ?

回答1:

Try stopping the capture process with ctrl+c instead of killing the process.

Also, you can try using pcapfix to fix your corrupted packets, it may help making your existing files readable again.

回答2:

If this is on UN*X, if you kill the process with kill -INTpid, then that will look just like a Ctrl+C. I'm not sure there's an equivalent on Windows.

I know this post is old, but in case anyone else runs across this:

The OP is probably running something like this:

tshark > capture.cap

And then killing it with CTRL+C. This will corrupt the file.

Instead of redirecting the output, use the -w option:

tshark -w capture.cap

Then you can kill it with CTRL+C and shouldn't have any corruption issues.
