Refusing to run as root without fallback UID specified

Why are you running as root ?

Not sure why. I have managed to get ptest to work and it outputs
Note: Using POSIX realtime
config string '0xdcb0 out'
Linux parallel port @56496 not found
halcmd:
When I do lspci I get
03:01.0 Parallel controller: Device 1c00:2170 (rev 0f)
03:02.0 Parallel controller: Device 1c00:2170 (rev 0f)
which I have assumed that as I have two cards in that I should have a parallel port.
Will look to see if I have the correct port address .I also had thgis

The address has changed to dca0.
That will happen as the assignment of resources in BIOS is set to Auto, so check if the BIOS has such a setting and set it to manually assign them.

"Why are you running as root ?"

When I used Nano I had to go into su to save file and should have come out back into where ptest is

Modified file today and ran ptest and got
hamish@Hamish:~/Downloads$ halrun -I -f ptest.hal
Note: Using POSIX realtime
config string '0xdca0 out'
Linux parallel port @56480 not found

"That will happen as the assignment of resources in BIOS is set to Auto, so check if the BIOS has such a setting and set it to manually assign them. " Thats today occupied once I figure out but ???

Before I go any further on another wild goose chase i have found the following
1 I can run the latency test on its own and its about 50000, however I cannot abuse the system as nothing will load.
2 I can open my browser and then launch the latency test and I loose control as mouse darts all over the place
3 I am using an old Dell Dimension 3100 and when I look at the Linuxcnc section "Hardware that works" it indicates ""No Built in Serial or Parallell Ports!!!"
In view of the above am I wasting my time with the Dell and if so any recommendations as to which hardware to get?
Thanks

I can get a refurbished unit off ebay for way under £50

That is old, so most of the issues are due to very limited RAM memory.
As for the parallel port, just have a look on the back side, there should be a female DB25 connector, violet colour, it is the biggest connector on the back.

Yes , there was one card and I added another, neither of which were violet in colour. I think I will look for a replacement either new or from ebay. I have noted a thread on this topic and will now read through it. I did increase RAM but will find out to what.

Back again. I now have a HP 500B MT desktop. My first problem came as it only had one port able to take the parallel port card and this was occupied by an Ethernet card even although there was an onboard Ethernet connection. After much trial and error freed up the port and internet now connected to onboard. Parallel port card now fitted and if enter lspci --vv the card appears with port reference. I change the reference in the tester but port is not found when attempting to run.

I am sure it must be simple but any advise would be appreciated.

Did you try it with the 0xe880 address?
