UNIX for Dummies Questions & Answers

Hi guys,

Quick traceroute query.

As part of some research I'm doing I need to send a traceroute to an equal number of IPv4 and IPv6 addresses on the net and basically capture the number of hops, and intermediate IP addresses from the traces.

This all needs to be automated as there are around 20K pairs of IP addresses.

When I've done some messing around with traceroute before to some of the addresses, some of the probes time out (as normal) on some of the hops, but some will just keep timing out until the maximum TTL is reached.

What I need to do to is be able to say "after * timeouts, stop the traceroute", is this possible? I want to avoid setting a max TTL if poss so as not to miss out some of the further away hosts.

I had a look through the man pages but didn't see anything that might help...

TIA

The -Q option is meant to do what I think you want. The default value for -Q is 5 timeouts.

Plus, there is no standard traceroute (POSIX) specification or implementation. You may not have a -Q option.

What platform are you on?

System Version: Mac OS X Server 10.6.7 (10J869)
Kernel Version: Darwin 10.7.0

I have -q but it's just to set the number of probes per TTL Any ideas?

A few other people I've spoken to have also mentioned this other version of traceroute with the -Q option. Is there somewhere I could go to search/download it?
