OK, so you can "see" the LDM at Penn State.

But, you can not "see" the LDM at College of DuPage.

This says that Penn State has allowed you to feed from it.

>Does the failover need to be changed on our side?

Yes.

>Looks like we'll need to do some configuring this afternoon.

Yup.  The configuration is easy.  All you need to do is change the
host portion of the request lines in your ~ldm/ldmd.conf file from
papagayo.unl.edu to ldm.meteo.psu.edu.  An easy way to do this is
to create two ldmd.conf file, one for papagayo and the other for
ldm.meteo.psu.edu.  This process is described in:

Unidata HomePage

    http://www.unidata.ucar.edu/packages/ldm
      LDM Setup 
      http://www.unidata.ucar.edu/packages/ldm/ldmConfigInstallList.html


Read through the section 'Configure a Failover site'.  It describes
the process of creating two ldmd.conf files and running a failover
script from cron.
