AlienVault OSSIM 4.2 - Enabling Custom Install

A tip that came up from a recent engagement was that with the release of the OSSIM installation ISO for version 4.2.0, the ability to do an Advanced installation is now disabled. Because we were performing a number of enterprise installations we really wanted to be able to customise many aspects of the initial installation, such as partitioning, mail servers, and more importantly, installation profiles.

The old AlienVault 4.1.0 installation ISO has the “Custom Install” option.

In order to get this functionality back within the default installation, you need to modify the boot parameters presented to you within the 4.2.0 ISO.

The boot parameters are currently:

/install.amd/vmlinuz preseed/file=/cdrom/simple-cdd/defaultA.preseed debian/priority=low vide=vesa:ywrap,mtrr vga=788 initrd=/install.amd/gtk/initrd.gz quiet AllinONEauto – vga=788

These are very hard to see within the modification window. You need to delete the “AllinONEauto” option, change the preseed/file option to “/cdrom/preseed”, and add the “preseed/interactive=true” option.

The final parameters will be:

/install.amd/vmlinuz preseed/file=/cdrom/preseed preseed/interactive=true debian/priority=low vide=vesa:ywrap,mtrr vga=788 initrd=/install.amd/gtk/initrd.gz quiet – vga=788

Enter this as the boot options, and now you will have access to the “Custom Installation” within the 4.2 ISO.
