traceroute replacement

[Radek Vokál]

Hi,

 there's a new package suggested as traceroute replacement. It works
without requiring a setuid bit. 

<snip>
This traceroute implementation relies on a number of features of the
2.4 Linux kernel. It works pretty much like ANK's tracepath, but 
tries to be command line compatible with the original traceroute.
I also has IPv6 support, and does parallel probes, which makes it
a little faster.
</snip>

The replacement is missing some options on which some scripts might
depend on. Please test the package 

http://people.redhat.com/rvokal/traceroute/traceroute-1.0.3-3.src.rpm

and report any problems to this bugzilla

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=172198


missing options are:

       -d     Enable socket level debugging.
       -I     Use ICMP ECHO instead of UDP datagrams.
       -r     Bypass the normal routing tables and send directly to a host on an
attached network.  If the  host
              is  not  on  a directly-attached network, an error is returned. 
This option can be used to ping a
              local host through an interface that has no route  through  it 
(e.g.,  after  the  interface  was
              dropped by routed(8C)).
       -v     Verbose output.  Received ICMP packets other than TIME_EXCEEDED
and UNREACHABLEs are listed.
       -x     Toggle ip checksums. Normally, this prevents traceroute from
calculating  ip  checksums.  In  some
              cases,  the  operating  system  can overwrite parts of the
outgoing packet but not recalculate the
              checksum (so in some cases the default is to not calculate
checksums and using -x causes  them  to
              be  calcualted).  Note  that  checksums are usually required for
the last hop when using ICMP ECHO
              probes (-I).  So they are always calculated when using ICMP.
       -z     Set the time (in milliseconds) to pause between probes (default
0).  Some systems such as  Solaris
              and  routers  such  as  Ciscos rate limit icmp messages. A good
value to use with this this is 500
              (e.g. 1/2 second).

differences:

-S = -s and -I = -i (! the above src rpm has a patch to use -i for interfaces as old traceroute)
