What's the specific OS & version?

Are you launching LinuxCNC manually after the system comes up, or automatically at startup via systemd (or initd or ???)?

For systemd, try: systemd-analyze <linuxcnc.servicename>

If you're launching manually, dig into your log files and use tools line strace to see what's going on behind the scenes.

...and if you don't have a network connection to the internet, make sure you disable all startup services (like ntp) that require internet connectivity to function or configure them to use only local network resources (perhaps "tick.localnetwork.com" or similar).

I have several special-purpose devices based on machinekit on the Beagle Bone.

In one case, we are using it in a hospital where they won't allow us to connect anything to their network.  So, we set up a point to point Ethernet link between a laptop and the Beagle Bone.  When starting LinuxCNC, there is a HUGE delay of about 10 minutes before the Axis GUI comes up.  I think I have traced it to be caused by there being no NTP time server.  I think we see the same delay with either a Linux or Windows computer used to access the Beagle.

Does this ring a bell with anyone?  Is there a workaround? (Process to kill or needs to be run?)

Thanks for any hints,

Jon
