We got our RoboRIO imaged today, and my first thought was whether I could use it on Linux without needing to plug it into a network. Turns out, this is a pretty simple thing to do!<\/p>\n

    \n
  1. Plug the RoboRIO in to your computer<\/li>\n
  2. Identify the network device, it should be something like\u00c2\u00a0enp0s29u1u2<\/em><\/li>\n
  3. Assign it an IP address like so:\n
    sudo ip addr add 172.22.11.1\/24 dev enp0s29u1u2<\/pre>\n<\/li>\n<\/ol>\n
    Now you need to start an DHCP server to give it an address, because FIRST didn’t give it a static address for some reason. You could modify the configuration on the RoboRIO… but let’s assume you don’t want to do that. Instead:<\/p>\n
      \n
    1. Download\u00c2\u00a0this python script that acts like a DHCP server<\/a><\/li>\n
    2. Run this:\n
      sudo python simple-dhcpd -a 172.22.11.1 -i enp0s29u1u2 -f 172.22.11.2 -t 172.22.11.2<\/pre>\n<\/li>\n<\/ol>\n
      And that’s it! When it works, you should get a message that says “Leased: 172.22.11.2”.<\/p>\n
      If it’s not working, here are some things to watch out for:<\/p>\n
        \n
      • Make sure your firewall allows port 67 on UDP<\/li>\n
      • Make sure dnsmasq or some similar program isn’t listening on port 67 (use “netstat -ln | grep 67” to check)<\/li>\n<\/ul>\n
        Things that would be nice to change:<\/p>\n
          \n
        • It’d be nice if FIRST changed the usb0 device to have a static address instead of depending on dhcp<\/li>\n
        • Probably should create a udev rule to make the network device something pretty<\/li>\n
        • When you disconnect the device, you have to run the scripts again. Probably should set something more permanent up, but this is good enough for now<\/li>\n<\/ul>\n
          Hope this helps you out!<\/p>\n","protected":false},"excerpt":{"rendered":"
