Required Kernel Tuning

Address Space Layout Randomization

FreeM shared memory is incompatible with address space layout randomization on FreeBSD 13 and newer.

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
