Linux Robots: nimldr install issues (hdb and spooler will not start)


Article ID: 35085

The controller starts but the hdb and/or spooler probes do not start after installation.

Error: nimldr: nimSessionNew - _probeCheckin failed - communication error

The robot will install, but the hdb and spooler probes will not start.  It looks like the following in Infrastructure Manager:


Component: CAUIM


Edit robot.cfg after the installation (add the IP on the ‘robotip = ‘ line) – save and restart the robot

Use the –R flag on the installer and specify the robot IP address:
   LINUX_23_64#  ./nimldr – R

Examine the ports and make sure none of them conflict. The commands are as follows:


netstat -ano | find "4800*"


netstat -anp | grep 4800

If the above steps do not resolve the issue, then:

Reboot the machine and then re-generate the magic keys

   To regenerate the magic keys:

  1. Stop the robot that has the problem probe (niminit stop)
  2. Move the controller.cfg to the changes folder, remove all magic_key = <blah> lines
  3. Activate the robot. (niminit start)
