Port Status
FreeBSD is a Tier 1 Port
Verified Releases
- FreeM 0.62.3 (27 Mar 2025)
- FreeM 0.62.2 (23 Mar 2025)
- FreeM
cvs-current - FreeM 0.62.1
Testing Details
- Bare-metal amd64 system
- FreeBSD 14.1-RELEASE-p2 amd64
- gcc 13.2.0
- autoconf 2.72
- automake 1.17
Required Kernel Tuning
FreeM in its default configuration requires just under 17MiB of shared memory. You can check the relevant kernel parameter with the following command:
$ sudo sysctl kern.ipc.shmmax
If kern.ipc.shmmax is less than 17000000, add the following lines to /etc/sysctl.conf and reboot:
kern.ipc.shmmax=17000000
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 13.2 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
Particularly astute system administrators will likely want to script this, which is an exercise left to the reader.
Starting Daemon Automatically
- Copy
scripts/freebsd-rc/freemto/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
Port Challenges
None.
