This post goes over how to sign a SplunkWeb Certificate Signing Request (CSR) using my Root CA in pfSense. I do not cover creating the Root CA. Step 1: Create the directory for the certificates splunk@siem:~$ mkdir /opt/splunk/etc/auth/certs Step 2: Generate the private key and temporary password splunk@siem:~$ cd /opt/splunk/etc/auth/certs splunk@siem:~$ splunk cmd openssl genrsa … Read more
Mounting disk images on Linux is fairly straight forward, however an image with a Logical Volume Manager (LVM) partition requires a little more attention. The first thing I do is find out some information about the image(s): root@box:# fdisk -l -o Device,Type,Size disk.img Device Type Size disk.img1 Linux 1G disk.img2 Linux LVM 952.9G -l lists … Read more
This is mostly a post to document my process of setting up Full Disk Encryption (FDE) using the Linux Unified Key Setup (LUKS) and the Logical Volume Manager (LVM). Most major distributions already enable this process at installation, however Slackware does not and it must be done by hand. I am going to use an … Read more

My FreeNAS server is a virtual machine (VM) on my Dell r710 server. I mount my NFS and CIFS Shares using AutoFS and configure my static routes to the NAS using the DHCP Server on my pfSense Appliance. AutoFS is software that uses the automounter of the Linux kernel to dynamically mount file systems on demand. … Read more
Disclaimer: A Root CA trusted by Active Directory should not be trivialized. Make sure you know what you are doing when working with PKI. Take the time to study the technology before implementing it in production environments. There hasn’t been any extensive testing of this setup, so your mileage may vary. I have a pfSense Security Gateway … Read more
Before we begin let us enable Services for NFS and both Sub Features. The typical way you will see an NFS share mounted in Windows involves mounting the remote file system using the anonymous (anon) user: mount -o anon \\192.168.28.155\mnt\NAS0\media G: This will give you read only access based on the configured permissions of the … Read more
