Hi, It appears as if the DS2450 is being reported as not connected even though it appears in the directory structure... This sounds like a problem that has been fixed that christian mentioned a few days ago in reply to my previous post.
Here is the results of my attempts to access the device...

The DS2450 now stays connected, but the files all have errors when you try to read them. I was going to email the error, but I am at work now, and I forgot to configure the box to allow ssh from outside, so I can't recreate it, I will send the error when I get home tonight.
