file uploading is a 3 stage process.
1) the client "opens" a file and is given one or more locations to
upload to.
2) the client uploads the file
3) the client "closes" the file

step 1 is where the server adds the tempfile entry, this doesn't involve
mogstored at all.  If the temporary file never actually appears on the
mogstored, which I bet it doesn't, your mogstored is broken, or at least
the port referencing it is wrong :-)

you can check to see if the mogstored is working or not by just trying
to upload and download a file from it, it's nothing special.  Barring a
permission problem, it is probably working fine.

my guess is that your host table in the database still references port
7500.  Also, since you never mentioned port 7501, you probably have to
fix that too.  7501 is only used for the size request, and would only
cause a slight slowdown if broken anyway.

You should be able to enable debugging in mogtool to see what port it
tries to connect to.

why not just use the defaults?
