At the same time, packet captures of the device behaviour will be recorded, alongside logs for each network service, for further debugging. + +## Minimum Requirements :computer: +### Hardware + - PC running Ubuntu LTS (laptop or desktop) + - 2x USB ethernet adapter (One may be built in ethernet) + - Connect one adapter to your router (for internet access) + - Connect one adapter to your device under test + - Internet connection +### Software + - Python 3 with pip3 (Already available on Ubuntu LTS) + - Docker - [Install guide](https://docs.docker.com/engine/install/ubuntu/) + - Open vSwitch ``sudo apt-get install openvswitch-common openvswitch-switch`` + +An additional network interface (even wifi) with internet access can be used to maintain internet connection during use of the network orchestrator. + +## How to use :arrow_forward: +1) Ensure you have a device with the minimum hardware and software requirements setup +2) Clone the project using ```git clone https://github.com/auto-iot/network-orchestrator``` +3) Navigate into the project using ```cd network-orchestrator``` +4) Copy conf/system.json.example to conf/system.json (after setting the correct interfaces in the file) +5) Start the tool using ```sudo cmd/start``` + +## Issue reporting :triangular_flag_on_post: +If the application has come across a problem at any point during setup or use, please raise an issue under the [issues tab](https://github.com/auto-iot/network-orchestrator/issues). Issue templates exist for both bug reports and feature requests. If neither of these are appropriate for your issue, raise a blank issue instead. + +## Roadmap :chart_with_upwards_trend: + - Ability to modify configuration files of each network service during use (via GRPC) + - IPv6 internet routing + +## Contributing :keyboard: +The contributing requirements can be found in [CONTRIBUTING.md](CONTRIBUTING.md). In short, checkout the [Google CLA](https://cla.developers.google.com/) site to get started. + +## FAQ :raising_hand: +1) What services are provided on the virtual network? + + The following are network services that are containerized and accessible to the device under test though are likely to change over time: + - DHCP in failover configuration with internet connectivity + - IPv6 router advertisements + - DNS (and DNS over HTTPS) + - NTPv4 + - 802.1x Port Based Authentication + +2) Can I run the network orchestrator on a virtual machine? + + Probably. Provided that the required 2x USB ethernet adapters are passed to the virtual machine as USB devices rather than network adapters, the tool should + still work. We will look to test and approve the use of virtualisation in the future. + +3) Can I connect multiple devices to the Network Orchestrator? + + In short, Yes you can. The way in which multiple devices could be tested simultaneously is yet to be decided. However, if you simply want to add field/peer devices during runtime (even another laptop performing manual testing) then you may connect the USB ethernet adapter to an unmanaged switch. + +4) Raise an issue with the label 'question' if your question has not been answered in this readme. \ No newline at end of file diff --git a/net_orc/docker-compose.yml b/net_orc/docker-compose.yml new file mode

At the same time, packet captures of the device behaviour will be recorded, alongside logs for each network service, for further debugging. - -## Minimum Requirements :computer: -### Hardware - - PC running Ubuntu LTS (laptop or desktop) - - 2x USB ethernet adapter (One may be built in ethernet) - - Connect one adapter to your router (for internet access) - - Connect one adapter to your device under test - - Internet connection -### Software - - Python 3 with pip3 (Already available on Ubuntu LTS) - - Docker - [Install guide](https://docs.docker.com/engine/install/ubuntu/) - - Open vSwitch ``sudo apt-get install openvswitch-common openvswitch-switch`` - -An additional network interface (even wifi) with internet access can be used to maintain internet connection during use of the network orchestrator. - -## How to use :arrow_forward: -1) Ensure you have a device with the minimum hardware and software requirements setup -2) Clone the project using ```git clone https://github.com/auto-iot/network-orchestrator``` -3) Navigate into the project using ```cd network-orchestrator``` -4) Copy conf/system.json.example to conf/system.json (after setting the correct interfaces in the file) -5) Start the tool using ```sudo cmd/start``` - -## Issue reporting :triangular_flag_on_post: -If the application has come across a problem at any point during setup or use, please raise an issue under the [issues tab](https://github.com/auto-iot/network-orchestrator/issues). Issue templates exist for both bug reports and feature requests. If neither of these are appropriate for your issue, raise a blank issue instead. - -## Roadmap :chart_with_upwards_trend: - - Ability to modify configuration files of each network service during use (via GRPC) - - IPv6 internet routing - -## Contributing :keyboard: -The contributing requirements can be found in [CONTRIBUTING.md](CONTRIBUTING.md). In short, checkout the [Google CLA](https://cla.developers.google.com/) site to get started. - -## FAQ :raising_hand: -1) What services are provided on the virtual network? - - The following are network services that are containerized and accessible to the device under test though are likely to change over time: - - DHCP in failover configuration with internet connectivity - - IPv6 router advertisements - - DNS (and DNS over HTTPS) - - NTPv4 - - 802.1x Port Based Authentication - -2) Can I run the network orchestrator on a virtual machine? - - Probably. Provided that the required 2x USB ethernet adapters are passed to the virtual machine as USB devices rather than network adapters, the tool should - still work. We will look to test and approve the use of virtualisation in the future. - -3) Can I connect multiple devices to the Network Orchestrator? - - In short, Yes you can. The way in which multiple devices could be tested simultaneously is yet to be decided. However, if you simply want to add field/peer devices during runtime (even another laptop performing manual testing) then you may connect the USB ethernet adapter to an unmanaged switch. - -4) Raise an issue with the label 'question' if your question has not been answered in this readme. \ No newline at end of file diff --git a/net_orc/conf/.gitignore b/net_orc/conf/.gitignore deleted file mode 100644 index 41b89ceb1..000000000 --- a/net_orc/conf/.gitignore +++ /dev/null @@ -1 +0,0 @@ -system.json \ No newline at end of file diff --git a/net_orc/conf/network/radius/ca.crt b/net_orc/conf/network/radius/ca.crt deleted file mode 100644 index d009cb1ab..000000000 --- a/net_orc/conf/network/radius/ca.crt +++ /dev/null @@ -1,26 +0,0 @@ ------BEGIN CERTIFICATE----- -MIIEYTCCA0mgAwIBAgIUQJ4F8hBCnCp7ASPZqG/tNQgoUR4wDQYJKoZIhvcNAQEL -BQAwgb8xCzAJBgNVBAYTAkdCMRswGQYDVQQIDBIbWzN+TGVpY2VzdGVyc2hpcmUx -FTATBgNVBAcMDExvdWdoYm9yb3VnaDEUMBIGA1UECgwLRm9yZXN0IFJvY2sxDjAM -BgNVBAsMBUN5YmVyMR8wHQYDVQQDDBZjeWJlci5mb3Jlc3Ryb2NrLmNvLnVrMTUw -MwYJKoZIhvcNAQkBFiZjeWJlcnNlY3VyaXR5LnRlc3RpbmdAZm9yZXN0cm9jay5j -by51azAeFw0yMjAzMDQxMjEzMTBaFw0yNzAzMDMxMjEzMTBaMIG/MQswCQYDVQQG -EwJHQjEbMBkGA1UECAwSG1szfkxlaWNlc3RlcnNoaXJlMRUwEwYDVQQHDAxMb3Vn -aGJvcm91Z2gxFDASBgNVBAoMC0ZvcmVzdCBSb2NrMQ4wDAYDVQQLDAVDeWJlcjEf -MB0GA1UEAwwWY3liZXIuZm9yZXN0cm9jay5jby51azE1MDMGCSqGSIb3DQEJARYm -Y3liZXJzZWN1cml0eS50ZXN0aW5nQGZvcmVzdHJvY2suY28udWswggEiMA0GCSqG -SIb3DQEBAQUAA4IBDwAwggEKAoIBAQDDNz3vJiZ5nX8lohEhqXvxEme3srip8qF7 -r5ScIeQzsTKuPNAmoefx9TcU3SyA2BnREuDX+OCYMN62xxWG2PndOl0LNezAY22C -PJwHbaBntLKY/ZhxYSTyratM7zxKSVLtClamA/bJXBhdfZZKYOP3xlZQEQTygtzK -j5hZwDrpDARtjRZIMWPLqVcoaW9ow2urJVsdD4lYAhpQU2UIgiWo7BG3hJsUfcYX -EQyyrMKJ7xaCwzIU7Sem1PETrzeiWg4KhDijc7A0RMPWlU5ljf0CnY/IZwiDsMRl -hGmGBPvR+ddiWPZPtSKj6TPWpsaMUR9UwncLmSSrhf1otX4Mw0vbAgMBAAGjUzBR -MB0GA1UdDgQWBBR0Qxx2mDTPIfpnzO5YtycGs6t8ijAfBgNVHSMEGDAWgBR0Qxx2 -mDTPIfpnzO5YtycGs6t8ijAPBgNVHRMBAf8EBTADAQH/MA0GCSqGSIb3DQEBCwUA -A4IBAQCpTMBMZGXF74WCxrIk23MUsu0OKzMs8B16Wy8BHz+7hInLZwbkx71Z0TP5 -rsMITetSANtM/k4jH7Vmr1xmzU7oSz5zKU1+7rIjKjGtih48WZdJay0uqfKe0K2s -vsRS0LVLY6IiTFWK9YrLC0QFSK7z5GDl1oc/D5yIZAkbsL6PRQJ5RQsYf5BhHfyB -PRV/KcF7c9iKVYW2vILJzbyYLHTDADTHbtfCe5+pAGxagswDjSMVkQu5iJNjbtUO -5iv7PRkgzUFru9Kk6q+LrXbzyPPCwlc3Xbh1q5jSkJLkcV3K26E7+uX5HI+Hxpeh -a8kOsdnw+N8wX6bc7eXIaGBDMine ------END CERTIFICATE----- diff --git a/net_orc/conf/system.json.example b/net_orc/conf/system.json.example deleted file mode 100644 index 77c981394..000000000 --- a/net_orc/conf/system.json.example +++ /dev/null @@ -1,7 +0,0 @@ -{ -
