System: NetBSD zorkmid.mit.edu 1.5U NetBSD 1.5U (ZORKMID-$Revision: 1.10 $) #103: Mon May 21 21:10:47 EDT 2001 jhawk@zorkmid.mit.edu:/usr/local/netbsd-current/src/sys/arch/i386/compile/ZORKMID i386


>Description:
	It sure would be nice if the ping program allowed the use of
-i 0.1 for non-root users. While -i 1 makes a nice default, it is not
unreasonable for users to want to get a more precise view of changing
network properties. Especially in a world where network properties are
increasingly relevent to users (our reliable Internet), and network
properties are increasingly unstable, especially with technologies like
wireless networking.

	I don't think that there is any trouble supporting 10pps of
diagnostic traffic, instead of 1pps, though I certainly agree that -i 0.1
should not be the default.

	CONCERN (for ippm people) is 10pps getting to the point where
it might be important to look into Poisson distributions? My feeling is
this should be done anyway, and that 10pps might be a level where it could
be easily done without interfering with the user, but there is no
compelling reason why this change should wait for a Poisson implementation.
>How-To-Repeat:

>Fix:
	Proposed patch.

 pkgsrc/net/mtr makes a nice way for users to *really* see how the
 network is changing.  i have a nice patch to make it *not* require
 gtk, but this email is too small for me to write it down...

 mtr, feh.

 Base OS, rah, rah.

 BTW, yes, I know the text in the printf had the number misentered
 as 0.01 instead of 0.1.
