Proposal for two minor improvements in prtraceroute

  • From: "Peder Chr. Norgaard" < >
  • Date: Thu, 6 Jan 1994 15:48:08 +0100 (CET)


	I have been using the prtraceroute tool (1.0.1 version) on large scale
for the first time, to verify routing through EuropaNET, and I have a request
for correction of an error and a request for improvement of readability of
output.  The tool is extremely useful as it is, but as the changes looks quite
easy to make I try anyway ...

	This run shows what I mean:

unix prompt# prtraceroute -v
traceroute with AS and policy additions [Jan  6 13:48:40 UTC] 

		from AS2043 (
		to   AS2043 (,
                     ^^^^^^                ^^^^^^^^^^^^^
 1 AS2043               (     [I]
 2 AS2043            (     [I]
 3 AS2043            (     [I]
 4 AS1128           (    [D1]

AS Path followed:  2043 1128

AS2043 = European Multiprotocol Backbone
AS1128 = DANTE Gateway in Amsterdam

	At first marking above the value should be AS1128, as specified by an
ias-int field in the database entry.  The prtraceroute program
discovers that correctly in line 4 below; it would be nice if it was shown
correctly in the header line too.

	At second marking above I would like to have the DNS name, again
as is found in line 4 below.  I cannot specify the DNS name in the argument
to prtraceroute, as I very often will do prtraceroute to destinations
where one DNS name covers several IP addresses, and I have to control
which IP address to go for.  Also, even when the prtraceroute destination
is finally reached (as in the case above) it is by no means certain that
the destination reply with the same IP address as the one I used for

	Please note, that I really want the line to read:

		to   AS1128 (,

even if it looks a bit awkward.  The much nicer

		to   AS1128 (

would be worse than now, because the reader of that text could be lead to
believe that the original call was

	unix prompt# prtraceroute -v

which is not the case.

Thank you in advance for considering these improvements.

best regards
