**On the host:**

1. `sudo echo 'security.jail.sysvipc_allowed=1' >> /etc/sysctl.conf`

2. `sudo echo 'jail_sysvipc_allow="YES"' >> /etc/rc.conf`

3. `sudo vi /usr/local/etc/ezjail/JAILNAME`

   Change this line:
  
   `export jail_JAILNAME_parameters=""`
  
   to:  
  
   `export jail_JAILNAME_parameters="allow.sysvipc=1"`

4. Restart the jail:
  
   `sudo ezjail-admin restart JAILNAME`
