well ... when the Detective began, host based firewalls were not
pervasive & the early goal was to pick ports that wouldn't normally
be used on a Win98 machine ... so we threw darts at the wall and
decided that the Detective would use the following ports:<br>
6666<br>
7777<br>
8888<br>
<br>
We're going to change this in the next "semi-release" to use well-known
ports (80, 21, etc.) to the Detective Server on Abilene which we hope
will pass thru "normal" host based firewalls. This will, we hope,
discourage end-users from turning off their host-based firewalls (and
thus generating more exposure to their machine).<br>
<br>
Any & all advice will be appreciated - if you prefer you can email
me or email <a class="moz-txt-link-rfc2396E" href="mailto:detective@internet2.edu">"detective@internet2.edu"</a>.<br>

<pre wrap="">hi,
could someone refresh my memory? doesn't the moo run over port
7777 also? and wasn't that also a problem due to that port being
blocked or squeezed because it was the napster port? (it was always
extremely slow for us; i guess there's a proxy now or something?).
seems like some other port number would be more useful in these
filtered environments. why is 7777 the port of choice?

not sure if there's a built-in tool in AG 2.0 but you can download a nice
little utility from detective.internet2.edu called internet detective. this
will test for multicast connectivity, connection to the Abilene network, and
bandwidth tests.

Note, though, that the new version of the tool runs over port 7777, and so may
get blocked by various P2P firewall rules.
