From another thread, I want to change the filter, replacing the one used by the capture.
I'm not certain that you can do that safely; libpcap's code isn't thread-safe, and I think that, when somebody last asked about this, I found some places where you could have a problem if you change a capture filter in one thread while you're capturing in another. That discussion is probably somewhere in the tcpdump-workers archives. - This is the TCPDUMP workers list.
