edit: Please pardon, just discovered the command I'm running automatically prompts for root access, which is why the exec node is kicking it back.
Leaving this here for the moment in case someone searches the same response, and needs to check their command instead...
Quite weird...
I initially tried to send 'sudo [command]', but got kicked back with errors related to the node not being able to take the sudo pw.
So I removed sudo from the commands. The exec node is still responding as if I'd sent Sudo.
I thought maybe it was the node, so I dropped in a new Exec node, and I get the same thing.
Any ideas? I have an ISP change out of state at my dad's in 2 hours, and just realized the vpn may not re-establish itself, so am trying to get NR to do it on ping fails.
