Re: roboRIO Connection Target issues (Failed to Ping)

I experienced the same symptom and it is unresolved. We have a workstation which works but the student insists that disabling all other adapters and rebooting the workstation after the roborio is disconnected from the router in any way is the fix.

Knowing that is not how IP networking works, I'm sure there is another answer.

The failing workstation is allocated the IP 10.45.37.67 (we are team 4537).
The router is set to 10.45.37.1 and I can ping that once connected to the wifi from the router.
I receive Unreachable icmp responses when trying to ping 10.45.37.2

The target in the project is default with a comment in the source indicating IP 10.TE.AM.2. The other workstation is using the exact same eclipse project with the same target specification (default).

These are the errors:
[echo] Finding roboRIO, please ignore any [hostinfo] error messages
[echo] Trying mDNS: roboRIO-4537-FRC.local
[echo] Trying DNS: roboRIO-4537-FRC.lan
[echo] Trying USB: 172.22.11.2
[echo] Trying Static Ethernet: 10.45.37.2
[hostinfo] Error retrieving remote host information for host:roboRIO-4537-FRC.lan.
[hostinfo] Error retrieving remote host information for host:roboRIO-4537-FRC.local.

I get the same result when plugging in to the router directly.
When plugging directly into the roborio, I do not get a DHCP address assigned.
I tried manually adding 10.45.37.2 to the hosts file but that didn't help (as the Unreachable problem appears to be the issue, not name resolution).


Rebooting the roborio did not change the behaviour. I have not tried rebooting the router. That will be an experiment for next weekend.


My first question is: For a working system, does the Roborio reply to ICMP Echo-request packets with a normal ping response?

My second: What protocols are used to deploy to the roborio?

My third: Has anyone "fixed" this in their experience?

Drew.
