# "Simple" init script for SBo ipxnet, by B. Watson <urchlay@slackware.uk>. If
# you need something fancier (multiple instances of ipxnet), feel free
# to implement it here and send me the updated script. I'll add it to
# the SBo build.
# Note that ipxnet daemonizes itself immediately (before even checking if
# it got the right number of command line arguments) and doesn't create a
# PID file. Trying to capture the PID of the just-spawned ipxnet process
# in this script is problematic, so I didn't bother with a PID file. We
# can't even capture error messages (because it closed its stdout/stderr).
# The default settings:
IPXPORT=19900
# If config file found, source it (can override IPXPORT)
[ -e /etc/rc.d/rc.ipxnet.conf ] && source /etc/rc.d/rc.ipxnet.conf

# give up.
