Hi Jennifer,

Good move!

OK.

Both forward and reverse DNS exist for your new machine, very good!

re:
> Our primary and secondary hosts are:
> 
> idd.meteo.psu.edu
> idd.unidata.ucar.gov

You should be able to REQUEST the same feeds on 'colaweb' that you are
REQUESTing on your other machines.  To verify this you can use the LDM
'notifyme' utility:

<as 'ldm' on colaweb.gmu.edu>

notifyme -vl- -f ANY -h idd.meteo.psu.edu

notifyme -vl- -f ANY -h idd.unidata.ucar.gov

If you see an OK line from each 'notifyme' invocation, it means that
you (colaweb) are ALLOWed to REQUEST data.  If you do not seen an OK
line, it will mean that the ALLOWs need some work (but I think you will
see the OK lines).

re:
> Thanks!

No worries.

Cheers,

Tom
