Do a better job of argument parsing. Don't permit ping -f to a multicast address (very antisocial). Don't permit -L, -I, -T options with unicast addresses. Ensure that we ask for only AF_INET addresses (should close PR#2584). Return <sysexits.h> error codes for failures. Document this. Fix man page to identify the author and put sections in correct order. |
