In general, we attempt to avoid gratuitous changes in output like this. We are out of options as well.. It was my intention that things like this would come with a name change to pktdump. pktdump would use all the same code, but have a different main(), which different (saner) options, and different defaults. So, a patch to change this, optionally by flag in ndo->ndo_NEWFLAG would be welcome, but I don't think we are going to change the default. -- ] 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
