I am considering adding a ZeroMQ decoder to Denis> tcpdump, to be particular. Currently the -T option is the only resort at the IP layer and UDP layer. It could apply to TCP too, perhaps. It would be nice to have a way for each ULP decoders to register their name so that it's not so switch() stmt based, and then to have a file which can be provided to map multiple ports at the same time. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr () sandelman ca http://www.sandelman.ca/ | ruby on rails [ _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
