Strange Error Regarding Connection with roboRIO
I keep getting this strange error:
BUILD FAILED C:\Users\*******\wpilib\java\current\ant\build.xml :345: com.jcraft.jsch.JSchException: java.net.ConnectException: Connection refused: connect Total time: 9 seconds I've tried anything I can think of... Anyone know what could be causing this? I believe it is my computer. Thanks for your time, Ryan |

Re: Strange Error Regarding Connection with roboRIO
There should be a message immediately in the build console before this error. Have you installed the JRE on your roboRio?

Re: Strange Error Regarding Connection with roboRIO
10 Minutes ago, I just re-imaged and reinstalled java on our roboRIO to see if that was the problem. It did not fix it. The only time I receive that error is when I attempt to connect wirelessly. Could it by my radio?

Re: Strange Error Regarding Connection with roboRIO
It could be, but does the DS connect? Can you ping the roboRio? Connect to the roboRio web console? If you're making it to that point in the script you should be able to get to the web console (as it makes a HTTP request to validate the image version immediately prior to that). Do you have any firewall software running? Might be worth downloading PuTTY and trying to ssh in manually to see if that works.

Re: Strange Error Regarding Connection with roboRIO
I can connect to and enable the robot through a connection with the D-Link. However, I can only deploy code over a bridge, and I cannot deploy code through a connection with the D-Link.
When i attempted to connect to the roboRIO by the IP Address I saw in Eclipse (which worked in Eclipse), puTTY gave me a similar error: "Connection refused". Not sure what to do from here except try other D-Links. Thanks, Ryan |

Re: Strange Error Regarding Connection with roboRIO
Can you ping these DNS names:
- roboRIO-589-frc - roboRIO-589-frc.local - roboRIO-589-frc.lan - roboRIO-589-frc.frc-robot.local |

Re: Strange Error Regarding Connection with roboRIO
Check your firewall on your computer. Temporarily disable it and see if deploying works. If yes, then re-enable your firewall and add a rule for outgoing port 21 connections.
If that doesn't work, try re-imaging your roboRIO |
