To run multiple copies of cl_status in one node, here is what you need to do:

Apply this patch to cl_status.c (This patch changes cl_status to signon as casual client. A casual client's name is the same as its process id)

Add the following line to the end of the file

apiauth default uid=<what_ever_id_u_use_to_run_cl_status>

Now compile cl_status and restart heartbeat.

Some slightly different thoughts on this subject:

  • make a new group just for this purpose
  • make cl_status setgid to that group
  • add this apiauth line instead of the one listed above:

apiauth default gid=<special_gid_created_above>
