HOWTO: Properly install native VMware Tools in pfSense 2.0.3 (FreeBSD 8.1)
Tags: FreeBSD, Open Source, security, VMware
If you’re anything like me, you take security seriously. With all the recent news about the NSA and Prism and over-reach of surveillance, you’ll take this very seriously. I run several layers of nested firewalls, VPNs and other layers of security at my office.
One of the things I run in a virtualized environment (VMware ESXi), is pfSense. pfSense ibs an Open Source firewall distribution based on FreeBSD. It’s very full-featured, has a web-management console, and lots of add-on packages to enhance it’s capabilities.
“pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. pfSense is a popular project with more than 1 million downloads since its inception, and proven in countless installations ranging from small home networks protecting a single computer to large corporations, universities and other organizations protecting thousands of network devices.”
pfSense is currently using FreeBSD 8.1, which has been EOL’d by the BSD team last July. The pfSense team is diligently working on new versions, but they’re not out yet. For now, you can continue to use FreeBSD 8.1.
If you run pfSense inside a VM, you’ll want and need to get the base VMware tools installed within it, but that process isn’t straightforward. You want to make sure you install the VMware Tools dependencies and core modules before installing anything else, so you don’t get into package conflicts and other troubles.
I’ve been writing a lot of posts about VMware lately, because I’m finding myself using it more and more, and I’m teaching myself how to use it in a higher-volume capacity.
Here’s how to install pfSense and immedaitely get the correct version of VMware Tools (from VMware itself, not the Open Source ‘open-vm-toolbox‘ or ‘vmfs-tools’) installed within it.
Let’s get started (click any images below to view them full-size):
- First, create a new VM and attach your pfSense ISO to it, using whatever mechanism your hypervisor of choice provides. Boot it, and install pfSense into your VM. This part is easy and straightforward.
- Once fully installed, shut down (power off) your VM, and detach the CD, so it no longer boots, but keep the CD/DVD device configured for your VM, you’ll use that again in a moment.
- Boot your pfSense VM back up, configure networking (in my case the NIC was em0), and you’ll get to a screen that looks something like this:

- From here, the first thing you want to do, is change your root password! Hit (8) to drop to a shell, and use the standard passwd(1) utility. Once changed, hit ^D (Control-D) to exit and return to the pfSense main menu.
- Next, we’re going to start SSHD, so we can log into the VM remotely, and manage it using a normal Windows, Mac or Linux terminal, vs. interacting with it using the VMware ESXi console (as in this example). Hit (14) to enable the SSH shell.
- In the previous screenshot, directly to the left of the (DHCP) part, was the IP of the pfSense server. SSH over to that now, as the root user, using whatever native terminal you prefer.
$ ssh root@192.168.1.50
- Once SSH’d into pfSense remotely, you’ll need to set the PACKAGESITE environment variable, to make sure all core packging tools refer to the 8.1-release tag from the FreeBSD archive site, and not the 8.1-release-p13 that it will try to use by default from the primary site, which will fail, because FreeBSD 8.1 is EOL as I write this.
-
[2.0.3-RELEASE][root@pfSense.localdomain]/root(1): setenv \ PACKAGESITE \ http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/
Here’s what will happen if you do not set this variable:
[2.0.3-RELEASE][root@pfSense.localdomain]/root(3): pkg_add -rv wget looking up ftp.freebsd.org connecting to ftp.freebsd.org:21 Error: Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-8.1-release/Latest/wget.tbz: File unavailable (e.g., file not found, no access) pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages-8.1-release/Latest/wget.tbz' by URL pkg_add: 1 package addition(s) failed
Once you set the variable to refer to the archive site, you’ll have success here:
[2.0.3-RELEASE][root@pfSense.localdomain]/root(5): pkg_add -rv wget looking up ftp-archive.freebsd.org connecting to ftp-archive.freebsd.org:80 requesting http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/wget.tbz Fetching http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/wget.tbz...x +CONTENTS x +COMMENT x +DESC x +MTREE_DIRS x man/man1/wget.1.gz x bin/wget ...
- Now we know we can get to the backup/archive site that holds the 8.1 RELEASE packages, let’s get the ones we need to get VMware Tools up and running. We’re going to need two core packages: compat6x-amd64 and perl to be able to run the script and dynamically load the VMware modules at kernel boot.
[2.0.3-RELEASE][root@pfSense.localdomain]/root(6): pkg_add -r compat6x-amd64 perl Fetching http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-8.1-release/Latest/compat6x-amd64.tbz...

Spamming /etc/make.conf... Done. Cleaning up /etc/manpath.config... Done. Spamming /etc/manpath.config... Done. - Now we need to mount the CD ISO for VMware Tools for FreeBSD. This is the step I mentioned earlier and why we needed to keep the CD/DVD device configured for this VM. In ESXi, you’ll need to do that from the console, by right-clicking on the VM, go to Guest and then to “Install VMware Tools”, as shown here:
- Now the drive is mapped to the VM, we need to mount it and access the vmware tarball within:
[2.0.3-RELEASE][root@pfSense.localdomain]/root(8): mkdir /tmp/cdrom/ [2.0.3-RELEASE][root@pfSense.localdomain]/root(9): mount_cd9660 /dev/acd0 /tmp/cdrom/ [2.0.3-RELEASE][root@pfSense.localdomain]/root(10): cd /tmp/cdrom/ [2.0.3-RELEASE][root@pfSense.localdomain]/tmp/cdrom(11): ls -l total 15030 -r--r--r-- 1 root wheel 29 Mar 23 15:02 manifest.txt -r--r--r-- 1 root wheel 15390306 Mar 23 15:02 vmware-freebsd-tools.tar.gz [2.0.3-RELEASE][root@pfSense.localdomain]/tmp/cdrom(12): tar zxvf vmware-freebsd-tools.tar.gz -C /tmp/
- Now we can go into /tmp/vmware-tools-distrib and build the required interfaces for FreeBSD. For the most part, you’ll just accept the defaults to most of the questions. Read them carefully if you think you want something custom for your needs.

Please remember to configure your network by adding: ifconfig_vxn0="dhcp" to the /etc/rc.conf file and start the network with: /etc/netstart to use the vmxnet interface using DHCP. Enjoy, --the VMware team
That’s it. You’ve now got a working VMware Tools install using the native, VMware-provided kit, inside your VM. If you’re running ESXi, you’ll now notice that it correctly reports its version, status and IP back to the console, which was missing before we started.
Good luck!
