[[AFT installation]]


=== 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 upon the hardness 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}
0 packages upgraded, 6 newly installed, 0 to remove and 459 not upgraded.
Need to get 470 kB of archives. After unpacking 1 884 kB will be used.
Do you want to continue? [Y/n/?]
</pre>
 
===== 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
</pre>
 
==== 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
The following NEW packages will be installed:
  dns-root-data{a} dnsmasq dnsmasq-base{a}
0 packages upgraded, 3 newly installed, 0 to remove and 459 not upgraded.
Need to get 0 B/329 kB of archives. After unpacking 886 kB will be used.
Do you want to continue? [Y/n/?
</pre>
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
 
1417132679 78:c5:e5:b4:4d:07 192.168.1.99 minox-fbe390b0bb404da *
1417134678 20:54:76:e4:d8:a5 192.168.1.57 minoy-ab6e5d0a524c9c7d *
......
.......
........ and so on...
</pre>
Above a common dnsmasq.leases file.
