OK - going through what is happening on a PPC (iMac) workstation.

# ps aux|grep ltspinfo
  257         root       2628   S   /bin/sh /etc/run_ltspinfod
  354         root       1460   R   /sbin/ltspinfod --nodaemon -s -r

so it's clear that the line in /opt/ltsp/ppc/etc/inittab
l:345:respawn:/etc/run_ltspinfod

is being executed (pid 257) and in turn, that tells the system to
execute /sbin/ltspinfod --nodaemon -s -r (pid 354) but it's clearly not
responding to port 9200
