Hi Yixin, re: > Thank you for your advice. We would like to have a try. Very good. I wish I could visit your campus to help troubleshoot this problem as I think it will turn out to be interesting. re: > We noticed that NUC > has just one ethernet port. Will a usb adaptor work for the second adaptor > that connect S300N? For testing purposes you will not need to relay the data off of the NUC, so only 1 Ethernet interface will be needed, and it will need to be configured for the subnet that your Novra S300N is connected to. To answer your question more fully, I can say that yes, a USB to Ethernet adapter can be used for the second Ethernet interface. One of our NOAAPort ingesters, leno.unidata.ucar.edu, is, in fact, a NUC configured this way, and it works very nicely (and fits in a small space, uses very little power and gives off very little heat so cooling is not needed). We are using a DodoCool USB to 3xUSB and 1xGbps Ethernet adapter. A quick Google (tm) search shows that it is available with 2-day free shipping: http://www.amazon.com/dodocool-Gigabit-Ethernet-Network-Adapter/dp/B00HVWAJ9C re: > Thanks. No worries. Please keep us informed about what you find in your testing.
