# inetd.conf This file describes the services that will be available

# through the INETD TCP/IP super server. To re-configure

# the running INETD process, edit this file, then send the

# INETD process a SIGHUP signal.

#

# In order to comply with the Linux Standard Base

# specification, many services are now configured

# via individual files in the /etc/inet.d directory.

#

#

# Builtin services (silently drop requests from ports < 512)

# WARNING WARNING WARNING

#

# When editing your inetd configuration manually, please

# edit the files in the /etc/inet.d subdirectory rather

# than inetd.conf. In particular, having entries for the

# same service both in inetd.conf and a file in /etc/inet.d

# is undefined.
