| === Setup harness server ===
| |
| ==== OS Installation ====
| |
| The Linux distribution installed upon harness server during the creation of this document was Ubuntu yakkety.
| |
| | |
| ===== Important facts upon installation =====
| |
| During Installation process of Ubuntu It'll be requested the creation of a user, please create the user with the name '''''tester'''''. Additionally the computer name will have to be '''''testing-harness'''''.
| |
| | |
| When installation has finished. The 'sudo group' has to be enabled as passwordless upon file '/etc/sudoers'.
| |
| <pre>
| |
| # Allow members of group sudo to execute any command
| |
| %sudo ALL=(ALL) NOPASSWD: ALL
| |
| </pre>
| |
| | |
| It is important to denote that user tester has been set as part of 'sudo group' by the default Ubuntu installation.
| |
| '''''With user tester is going to be executed the overall of automated testing'''''.
| |
| | |
| ===== Ram and Disk distribution =====
| |
| The Ram and Disk details this harness server during the creation of this document were:

| |
| | |
| ==== Firewall configuration ====
| |
| Firewall configuration is not provided, it is recommended that the testing harness is only kept in a trusted network.
| |
| | |
| To check if no firewall are configured over testing-harness, we can expect a similar output when inquiring iptables...
| |
| <pre>
| |
| root@testing-harness:~# iptables -L && iptables -t nat -L
| |
| Chain INPUT (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain FORWARD (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain OUTPUT (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain PREROUTING (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain INPUT (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain OUTPUT (policy ACCEPT)
| |
| target prot opt source destination
| |
| | |
| Chain POSTROUTING (policy ACCEPT)
| |
| target prot opt source destination
| |
| </pre>
| |
| | |
| ==== 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 ====
| |
| 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 =====
| |
| The tester’s home will be set as shared directory
| |
| <pre>
| |
| root@testing-harness:~# cd /etc
| |
| root@testing-harness:~# echo '/home/tester 192.168.1.0/24 (crossmnt,ro,root_squash,sync,no_subtree_check)' >> 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 *
