GNet Solutions » FreeBSD Administration

I recently tried to install PostgreSQL in a FreeNAS 9.10 jail, only to see that SysVIPC must be enabled in the jail for it to work. This is a simple procedure for enabling SysVIPC in a FreeNAS 9.10 jail.

Enable SysVIPC on the Host¶

• Log into the FreeNAS administration panel and go to System -> Tunables

• Next click Add Tunable and add the following:
  1. Variable: security.jail.sysvipc_allowed
  2. Value: 1
  3. Type: Sysctl
  4. Comment: Enable SysVIPC
  5. Enabled: [X]

• Reboot the FreeNAS machine, just to be safe.

Create a SysVIPC Enabled Jail¶

• From the FreeNAS administration interface, go to Jails.

• Next click Add Jail and add the following:
  • Jail Name: jail.example.com
  • Sysctls: allow.sysvipc=1
    NOTE: Make sure if appending the sysctl to additional options to use comma separation, example allow.raw_sockets=true,allow.sysvipc=1

• Click OK

Now the jail.exmaple.com will have SysVIPC available for programs to use.
