What do you mean by "postfiltering"?

If you mean that you have a capture file and you want to make a new
capture file that has the same packets but that limits them to a maximum
of N bytes, just as if the capture had been done with a snapshot length
of N, then you can use the editcap utility to read the capture file and
write out a new file:

	editcap -s N oldfile newfile

which will read the capture file "oldfile" and write out a new capture
file "newfile"; packets in "newfile" will be truncated, if necessary, so
that no more than N bytes of packet data are present.
