While performing a patch to /usr/sbin/arp to add the "-n" option, I noticed that it already existed! The man page says nothing about it. :) The only problem with using it is that it gets ignored when doing "arp -a -n", because when the "-a" option is seen in the switch() after getopt(), dump(0) is called immediately, and then arp exits. The "-n" option must be first in order for it to work. I can imagine that when, one fine day, the "-n" option IS documented, that a user goes "arp -a -n" and sees the program hang doing a DNS lookup, he/she is going to be pissed that it doesn't work. :) That's what has been happening to me. :) -------------------------------------------------------------------- Mark J.
