Set Up NTP On An Ubuntu Machine With No Internet Access

NTP is a requirement for the Interset products to function correctly.  On an internet connected machine, this can be installed using normal Ubuntu wget commands.

However, for a machine that does not have connectivity, the follwoing packages will need to be downloaded and moved to the machine via alternative means (EG, USB key, internal FTP) and installed using the following commands:

Ubuntu 12.04.5

1.  Download libopts25_5.12-0.1ubuntu1_amd64.deb from an internet connected machine

2.  Download ntp_4.2.6.p3+dfsg-1ubuntu3.3_amd64.deb from an internet connected machine

3.  Copy the files from the local machine to the /home/ubuntu folder on the server

4.  Run sudo -dpkg -i libopts25_5.12-0.1ubuntu1_amd64.deb

5.  Run sudo -dpkg -i ntp_4.2.6.p3+dfsg-1ubuntu3.3_amd64.deb

Ubuntu 12.04.4

1.  Download libcap2-bin_2.17-2ubuntu_amd64.deb from an internet connected machine

2.  Download libcap2-2.22-1ubuntu3_amd64.deb from an internet connected machine

3.  Download libopts25_5.12-0.1ubuntu1_amd64.deb from an internet connected machine

4.  Download ntp_4.2.6.p3+dfsg-1ubuntu3.3_amd64.deb from an internet connected machine

5.  Copy the files from the local machine to the /home/ubuntu folder on the server

6.  Run sudo -dpkg -i libcap2-bin_2.17-2ubuntu_amd64.deb

7.  Run sudo -dpkg -i libcap2-2.22-1ubuntu3_amd64.deb

8.  Run sudo -dpkg -i libopts25_5.12-0.1ubuntu1_amd64.deb

9.  Run sudo -dpkg -i ntp_4.2.6.p3+dfsg-1ubuntu3.3_amd64.deb

Once everything is installed, configure NTP to point to a domain controller.  This will sync the time appropriately and will prevent the system from becoming out of time sync which can cause issues with the writing of data.
