yeah, so, i'm convinced that the tool i'm using is working, and it's the server that isn't. 

ugh.

1) the carleton site gives out a 503, indicating the traffic isn't being allowed by the server. but, i can access it from the web portal.
2) the tripod site gives out a 403, indicating that i'm not allowed to access it - which is also what happens when i search from the web portal.
3) the crosswinds site gives out a 404, telling me that it isn't there at all. that's fine.

if i go to something like nirvana.com, though, it lets me download the snapshots.

so, everything is working the way it's supposed to.
