Re: [solved] RPi 3b no internet access ??

It appears my gut was right. I re-imaged the SD in both units using the most current package. Everything works perfectly. They are working well enough that I could do what I was planning. I installed a Rasclock in both following the directions on their website. They are functioning correctly with in...

[solved] RPi 3b no internet access ??

I am working with two RPi 3b. When I set them up, they accessed the internet just fine. Now neither one will. :cry: They will connect to Ethernet and WiFi, but they can't bring up the internet. I have tried replacing cables, tried on multiple networks, made sure the PS was putting out enough, and ut...

Re: Jessie Q&A

It's no problem at all. NTP uses a polling system to connect when possible to the reference server. The connections are done using UDP/IP which isn't a reliable connection unlike TCP/IP. If a packet goes missing with UDP/IP nothing matters. I don't understand how that points my Pi to my local NTP s...

Re: Jessie Q&A

I am new to Linux administration. I have a project that will use RPis as time clock terminals linking to a central server for database, reporting, and time sync. All of the units will be on a local network with no access to the outside world / internet. Setting up the NTP server on a Windows box as ...

Confirm JavaFX on PI

I have tried to run a simple JavaFX application on my PI. It will not run on the PI although it runs fine on Windows and Mac test computers. Reading at Oracle it seems to say that JavaFX is not supported on the ARM (PI) version of Java. Can anyone confirm that JavaFX is not in the current release of...

Printing with Java on PI 2

I am looking at creating a simple time clock. It will read barcoded id badges from an HID USB scanner. Most of it is simple to implement. Where I am stuck is when I consider writing the application in C# .net and using an old PC, or writing it for the Raspberry PI in Java. (I do not have any Java ex...
