Required Kernel Tuning

Address Space Layout Randomization

FreeM is incompatible with address space layout randomization (ASLR), which is enabled by default on FreeBSD 13.2 and newer on 64-bit platforms.

To use FreeM on FreeBSD 13 and newer, add the following lines to /etc/sysctl.conf and reboot:

kern.elf64.aslr.pie_enable=0
kern.elf64.aslr.enable=0

If you do not wish to globally disable ASLR on your system, you can use FreeM by disabling it per-process with each invocation by using the following syntax:

$ proccontrol -m aslr -s disable freem

Starting Daemon Automatically

• Copy scripts/freebsd-rc/freem to /usr/local/etc/rc.d
• Type the following commands with root privileges:

# pw group add freem
# pw user add freem -m -g freem
# sysrc freem_enable="YES"
# chmod +x /usr/local/etc/rc.d/freem

• For each user who needs to run FreeM, type the following command:

# pw group mod freem -m username

• Reboot
