If the machine access check in the NORSAR-3D Common Shot Wavefront Tracer - Batch fails, check the following:

  1. The access check needs rexec enabled on the remote machine:

    cd /etc/xinetd.d 

    Ensure that it says disable = no in rexec

    /etc/rc.d/init.d/xinetd reload
  2. TCP port 514 must be open.
  3. The user must have the same home directory on both machines, or the same .rhosts file.
