# "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)
|
|
