ee2bf73496 1) Minor nits in the usage message from bde. I took out the hard tabs and
used spaces to align the second line under the program name.
2) Cache uid after call to setuid(getuid()) so we don't waste a system call
   for each packet with a call to getuid for the -v case.
3) Update manual to reflect new restriction on -l from last delta.

f78ac61b3a 1) Fix usage to match convention and manual. Fix manual to match usage.
2) Must be root to run preload (OpenBSD ping.c 1.8)
3) Don't print all replies unless verbose and root (from idea in
   OpenBSD ping.c 1.10 and 1.11) to avoid leaking information available
   only to root.
4) Remove unused h: from option string to getopt.
5) Make the compiler happy with exit(0) (Lite-2?)

Good candidate for 2.2 and 2.1 (as are many of the 1.17 changes).

43470e3be8 Make ping -Wall clean (except for one warning).
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.

Add '-a' audible flag, so terminal will beep upon receipt of a reply
packet.  Useful for debugging ethernet runs, among other things.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

854569350f Add multicast options -I (source interface), -T (set ttl), -L (no loopback).
They were all lowercase in the original, but our ping already uses -i and
-l so I made them all uppercase.

7d81b35c91 Cleaned up recent SIGINFO changes.
Simplified average calculations.  This also fixes potential overflow errors
and minor rounding inconsistencies (always round to nearest now).

Don't lose more SIGINFOs than necessary.

Print \r at the start of the status message.  This clears the dots that
are sometimes left by ping -f.

37e5b2c618 Change how SIGINFO is handled -- set a flag (of sig_atomic_t), and check
that flag on every iteration of the loop.  This avoids calling fprintf
inside a signal handler, which is always somewhat icky.

4055611a53 Move the terminal handling code to a later location; this allows
the signal handlers to be set up; it also means that a failed name lookup
won't mess up the nokerninfo setting of the tty.

ef9e6dc7ee Print out ICMP errors that are responses to our own packets by default.
Turn this behavior off using '-Q'.  This makes '-v' useless other than as
an ICMP-sniffer, which tcpdump is better at anyway.

Print out another couple of ICMP messages, and fix the printing of the
original packet (mostly byte order problems).

efa3853949 Limit the risk of `buf' overrun in ping.c when printing hostnames.
Note, this is not really a security risk, because the buffer in question
is a static variable in the data segment and not on the stack, and hence
cannot subert the flow of execution in any way.  About the worst case was
that if you pinged a long hostname, ping could coredump.

6e1173dc29 In past releases of FreeBSD, I have used the exit status of "ping" to
determine whether a connection to a given machine is up or not.

In FreeBSD 2.0 (and therefore, I assume, BSD 4.4) the exit code of ping
is always zero, even if no packets were received.

I would like to propose the following change to /usr/src/sbin/ping/ping.c
to restore this useful behaviour:

kernel printing of information and restore it on exit.  Now, it needs
an option to be quiet. ;)
