Rtapi memory errors

has anyone run into this I have kinda hit a wall and am looking for some insight

rtapi_shmem new failed due to shmget(key=0x48484c34): Permission denied
rtapi_init: could not open shared memory for uuid
HAL LIB: ERROR: rtapi init failed
hal lib: rtapi app main: Invalid argument (-22
Note: Using POSIX non-realtime
tpnod: dlopen: /usr/Llib/linuxcnc/modules/tpnod. so: undefined symbol: hal init

<commandline>:0: insmod for tpmod failed, returned -

Try running the included parallel port configs, although they may complain about not running a real time kernel. From your error report means you are not running a real time kernel.
To check, open a terminal and type "uname -a"
What Linux version are your running?
 

here is the vesion
Linux LinuxCNC 6.12.101+debl3-rt-amd64 #1 SMP PREEMPT RT Debian 6.12.101-1 (2026-08-05) x86 64 GNU/Linux

If I run a parallel port config it gives me the same error. I have reinstalled the OS 3 times with 2 different versions of LinuxCNC and the error before I get this one is always about lcec not found
