Recently I’ve been working in a couple of different \/ disconnected labs. This means I’m managing a couple copies of all my templates manually. Sometimes its hard to find the right section of my notes depending on when\/where I’m working on the lab, so I decided to post a couple quick blog posts so I can always find them. The following notes are for creating a template based on Ubuntu 16.04.1, and include notes on setting a static IP and joining to the domain with pbis-open (formerly likewise-open). <\/p>\n

Install Ubuntu 16.04.1 Server from ISO image (http:\/\/www.ubuntu.com\/download\/server\/thank-you?version=16.04.1&architecture=amd64<\/a>), accepting all defaults. When prompted for an admin user, use the name hostadmin.<\/p>\n

Once the install is complete, login as hostadmin. Switch to root and set a password for the root user.<\/p>\n

\r\nsudo su -\r\npasswd\r\n<\/pre>\n
Apply updates and install the packages openssh-server and ntp:<\/p>\n
\r\napt-get update && apt-get upgrade\r\napt-get install openssh-server ntp -y\r\n<\/pre>\n
Get the template ready for PowerBroker Identity Services (formerly likewise-open) domain joins:<\/p>\n
\r\nwget http:\/\/download1.beyondtrust.com\/Technical-Support\/Downloads\/PowerBroker-Identity-Services-Open-Edition\/pbiso\/850\/pbis-open-8.5.0.153.linux.x86_64.deb.sh\r\nchmod +x pbis-open-8.5.0.153.linux.x86_64.deb.sh\r\n.\/pbis-open-8.5.0.153.linux.x86_64.deb.sh\r\ncd \/opt\/pbis\/bin\/\u00a0\r\n<\/pre>\n
At this point, I shutdown the VM and convert it to a template.  When I’m ready to use the VM, I deploy a copy from template and follow the remaining steps.<\/p>\n
If needed, set a static IP by updating the following file:<\/p>\n
nano \/etc\/network\/interfaces<\/pre>\n
The important sections to include in the iface settings are address, netmask, gateway, dns-search, and dns-nameservers.  An example has been included below:<\/p>\n
\r\niface eth0 inet static\r\naddress 192.168.0.100\r\nnetmask 255.255.255.0\r\ngateway 192.168.0.1\r\ndns-search lab.enterpriseadmins.org\r\ndns-nameservers 192.168.0.20\r\n<\/pre>\n
Verify that the hostname is properly set:<\/p>\n
nano \/etc\/hostname<\/pre>\n
Join the Linux VM to the domain and create a DNS record:<\/p>\n
\r\ndomainjoin-cli join lab.enterpriseadmins.org adminbw\r\n\/opt\/pbis\/bin\/config AssumeDefaultDomain true\r\n\/opt\/pbis\/bin\/config LoginShellTemplate \/bin\/bash\r\n\/opt\/pbis\/bin\/config HomeDirTemplate %H\/%U\r\n\/opt\/pbis\/bin\/config RequireMembershipOf \"lab\\\\domain^users\"\r\n\/opt\/pbis\/bin\/update-dns\r\n<\/pre>\n
Once I reach this point, I kick off a quick reboot (just to make sure the domain join took) and am now free to use the VM.  <\/p>\n","protected":false},"excerpt":{"rendered":"
