Server Installation

Installation Media

The installations media for pascom virtual and server appliances will be shipped directly with your licence purchase from the pascom ISO distribution. The pascom Community installations media is available to download from the download section on our website under

A pascom Community instance can upgraded to a pascom Virtual at any time. Therefore, you are free to use the Community Version for testing purposes and then later on upgrade your system and transfer all your data.

Installing in a Virtual Machine

The pascom ISO file is effectively a conventional installation CD. You will need to setup a virtual machine and then use the ISO file as a boot media in order to carry out the pascom installation. The ISO file can also be used to install pascom directly on to a hardware based server.

System Requirements

In effect, pascom operates on the assumption that it is installed in a virtual environment, meaning that pascom can operate under Windows, Linux and OSx. pascom has been extensively tested within the following virtualization solutions:

  • VMWare ESX, Fusion, Server, Player, Workstation
  • Sun (Oracle) Virtual Box
  • XEN in varying distributions
  • Microsoft Hyper-V

Should you wish to use the ISO Distribution, then you will need to add the virtual machine yourself which should have the following hardware settings:

  • Min. 16 GB harddrive
  • Min. 1x Network card
  • Min. 1 GB RAM

Should you not be experienced with virtualisation solutions, our recommendation would be to use the following free of charge VMWare Players for Windows and Linux. Alternatively, you can also use Oracle’s Virtual Box.

Installing on Server Hardware


Using any Windows PC or Linux system, you can copy a pascom ISO file or a backup of version 7.01.00 or higher to a bootable USB stick, which can then later be used to install pascom.

Creating an Installations Media in Windows


Download a pascom setup file (mobydick 7.11.07 or later) from or use the file appliance.iso from a backup (applicable for mobydick versions 7.11.07 or later). Download the application Rufus which contains a tool with which to create a boot USB stick.

Creating a bootable USB stick

Start Rufus and connect a USB stick Screenshot - Create bootable USB Stick

Parameter Meaning
Device Select the USB stick volume name from the device drop down list
Create a bootable disk using ISO Image and then by clicking on the disk symbol, select the previously downloaded ISO file

In the next window, select “write in ISO Image mode”: Screenshot - ISOHybrid Image detected

Unattended Installation

In order to proceed with an unattended pascom installation, you will need to adjust a few settings. Open the USB Stick and click on the file unattended_install Screenshot - Unattended Installation

A window screen will now appear in which you can enter your settings:: Screenshot - Unattended Installation Settings

Check the show output during installation via COM port box so the unattended pascom installation can be monitored over the COM Port. Click Generate. After ejecting the USB stick, the medium can be used to carry out the installation.

Please note that unattended installations on a mini appliance can take upto 15 - 20 minutes, during which time the system must NOT be restarted. Should the device restart, the installation will fail. After the 15 - 20 minutes time period, the installation is deemed successful as soon as you are able to successfully login via the web UI without any error notifications. It is also recommended to check your Icinga monitoring checks.

Creating an Installations Medium Using a Linux System


Download a pascom setup file (version 7.01.00 or higher) from or use the file appliance.iso from a backup (version 7.1 as a minimum). The easiest method to create the USB Installation Disk is to use your pascom server or any Linux system that has syslinux installed. If you want to use your pascom system, copy the ISO file to the folder /etc/admin/ on a mobydick 6 or 7 system and log on to the system using SSH. Further information can be found in Accessing pascom.

Creating a bootable USB stick

You are currently logged on as the user: admin, and in accordance to the steps above, the ISO file can be found at /etc/admin.

Become root:


Connect USB-Stick to pascom Server and check whether it is detected:


The output shows which name the USB stick was assigned within the system (sdb in our case):

usb 1-1: new high speed USB device using ehci_hcd and address 2
usb 1-1: configuration #1 chosen from 1 choice

Create folders and mount the ISO file:

mkdir /tmp/iso
mkdir /tmp/usb
mount -o loop /etc/admin/dist-7-stable-pascom-\*.iso /tmp/iso/

Format the USB stick and mount it:

Replace DEVICE with the USB device that you just created (e.g. sdb)

mkfs.msdos -I /dev/DEVICE
mount /dev/DEVICE /tmp/usb/

Copy the data to the USB stick and create a boot loader configuration:

cp -arv /tmp/iso/. /tmp/usb/
cp /tmp/usb/isolinux.cfg /tmp/usb/syslinux.cfg
umount /tmp/iso
umount /tmp/usb

Install bootloader to the USB stick:

Replace DEVICE with the USB storage device (e.g. sdb)

syslinux /dev/DEVICE
