Traceroute is setuid root. Current version is more widely used, and I dare say,
better audited. The privileges are dropped earlier. It also seems that
nikhef traceroute isn't being too actively maintained.
I'm not sure if the switch is needed.
However, I'm all in for merging some features if someone cares enough to do the job.
It seems that there are following new (at least marginally useful) options in there:
-A Look up the AS-number (Autonomous System) for each
hop's network address at the whois server specified
by the -h option.
-a If the destination host has multiple addresses,
traceroute will probe all addresses if this option
is set. Normally only the first address as returned
by the resolver is attempted.
-h server
Specify the name or IP address of the whois server
that will be contacted for the AS-number lookup, if
the -A option is given.
-k Keep the connection to the whois server permanently
open. This will speedup lookups considerably, since
otherwise a connection needs to be set up for each
individual lookup. Unfortunately, not all whois
servers support this feature.
-l Print the value of the ttl field in each received
packet (this can be used to help detect asymmetric
routing).
-Q maxquit
Stop probing this hop after maxquit consecutive
timeouts are detected. The default value is 5. Use-
ful in combination with -S if you have specified a
big nqueries probe count.
-S Print a per-hop min/avg/max rtt statistics summary.
This suppresses the per-probe rtt and ttl reporting.
For better statistics you need to increase the
default nqueries probe count. See also -Q.
AS related settings are neat but only useful for those that even know what they
are (<5%) or are acquainted with them (<1%). :-)
This leaves -a, -l, -Q, -S. -Q looks very interesting, -l might also be rather useful.
I think we'll stay with the current version for the mentioned reasons. Read ya, Phil |
