|
| === Setup harness server ===
| | [[Manteiner python3-numpy]] |
| ==== Setup Security shell ====
| |
| OpenSSH is a freely available version of the Secure Shell (SSH) protocol family of tools for remotely controlling, or transferring files between, computers. That's why it is required its installation upon testing-harness server.
| |
| <pre>
| |
| root@testing-harness:~# aptitude install openssh-server
| |
| </pre>

|
| ==== Setup NFS ====
| | [[Arduino Single power control unit]] |
| AFT applies Network file system to share /home/tester directory where images and other files used in flashing for PC-devices within AFT net can be found.
| |
| | |
| ===== NFS is installed ? =====
| |
| To check if the NFS server is installed, we can do...
| |
| <pre>
| |
| root@testing-harness:~# dpkg -l | grep nfs-kernel-server
| |
| </pre>
| |
| | |
| ===== How to install NFS ? =====
| |
| To install NFS these are the required packages...
| |
| <pre>
| |
| root@testing-harness:~# aptitude install nfs-kernel-server
| |
| The following NEW packages will be installed:
| |
| keyutils{a} libnfsidmap2{a} libtirpc1{a} nfs-common{a} nfs-kernel-server
| |
| rpcbind{a}

| | |
| ===== Sharing /home/tester directory =====
| |
| <pre>
| |
| root@testing-harness:~# mkdir -p /home/tester
| |
| root@testing-harness:~# echo '/home/tester 192.168.1.0/24 (crossmnt,ro,root_squash,sync,no_subtree_check)' >> /etc/exports
| |

| ==== Setup DNS cache and DHCP server for AFT net ====
| |
| DNSmasq provides two services, either of which can be used independently.
| |
| # DNS service
| |
| # DHCP service
| |
| | |
| A local DNS cache can speed up internet browsing because the user's applications will not need to access a domain name server when it looks up a domain name the computer has visited before.

| ===== How to install dnsmasq ? =====
| |
| To install dnsmasq these are the required packages...
| |
| <pre>
| |
| root@testing-harness:~# aptitude install dnsmasq
| |

| |
| At the sametime we have set up a simple DNS server. To test it, use your favorite DNS lookup tool pointed at localhost
| |
| <pre>
| |
| root@testing-harness:~# nslookup yoctoproject.org localhost
| |
| Server: localhost
| |
| Address: 127.0.0.1#53
| |
| | |
| Non-authoritative answer:
| |
| Name: yoctoproject.org
| |
| Address: 140.211.169.56
| |
| </pre>
| |
| | |
| ===== Configure DHCP server =====
| |
| To enable the DHCP server of AFT net, you will need to give it a range of IP addresses to hand out. The AFT net server would hand out 92 address starting at 192.168.1.2 and ending at 192.168.1.99.
| |
| <pre>
| |
| root@testing-harness:~# echo 'dhcp-range=192.168.1.2,192.168.1.99,10m' >> /etc/dnsmasq.conf
| |
| </pre>
| |
| | |
| To tell dnsmasq which ethernet interface it can and cannot listen on.
| |
| <pre>
| |
| root@testing-harness:~# echo 'interface=eno1' >> /etc/dnsmasq.conf
| |
| </pre>
| |
| During the creation of this document the interface eno1 is the unique one connected to AFT net.
| |
| | |
| ===== AFT and its relation with dnsmasq.leases =====
| |
| As of dhcp server is up and running. AFT shall utilize dhcp-server's active ip leasing information to determine device IP address of PC-devices over AFT net. By default it is found upon /var/lib/misc/dnsmasq.leases
| |
| <pre>
| |
| root@testing-harness:~# cat /var/lib/misc/dnsmasq.leases
| |
| | |
