Hi Xiaodong,

This address works much better:

Yes, this shows that the "imas" address won't work with your upstream
feed.  I'll send the Albany people a note and ask him to change the name
in his configuration file.  

Oh - I just got an email from them, looks like they've already made that
change.  Let me know if this solves your problem.

I'm pretty sure the LDM won't require the portmapper once it's started,
so you're ok for the time being.  But, if you needed to stop and restart
your ldm for any reason, it won't start unless the portmapper's running. 

If you'd like to know how to start the portmapper, let me know what
operating system you are running.
