This code has +been tested on Debian and Redhat Linux. It may work on other platforms. +It *will not* work on Darwin or Mac OS X - the necessary functionality is +already built into the operation system. + + +# Building and Installing: + +See "ReadMe.txt" for instructions on building and installing. + +When you run "make install" as described in that file: +o libnss_mdns-0.2.so and libnss_mdns.so.2 are installed in /lib, +o manual pages libnss_mdns(8) and nss_mdns.conf(5) are installed, +o nss_mdns.conf is installed in /etc, and +o /etc/nsswitch.conf is modified to add "mdns" on the "hosts:" line + +This will cause dns lookups to be passed via mdnsd before trying the dns. + + +# Testing + +For most purposes, 'ping myhostname.local' will tell you if mdns is +working. If MDNS_VERBOSE was set in nss_mdns.c during compilation then +lots of chatty debug messages will be dumped to LOG_DEBUG in syslog. +Otherwise, nss_mdns will only log if something isn't behaving quite right. + + +# Implementation details + +libnss_mdns provides alternative back-end implementations of the libc +functions gethostbyname, gethostbyname2 and gethostbyaddr, using the Name +Service Switch mechanism. More information on writing nsswitch modules +can be found via 'info libc "Name Service Switch"', if installed. + + +# Licensing + +This software is licensed under the NICTA Public Software License, version +1.0, printed below: + +NICTA Public Software Licence +Version 1.0 + +Copyright © 2004 National ICT Australia Ltd + +All rights reserved. + +By this licence, National ICT Australia Ltd (NICTA) grants permission, +free of charge, to any person who obtains a copy of this software +and any associated documentation files ("the Software") to use and +deal with the Software in source code and binary forms without +restriction, with or without modification, and to permit persons +to whom the Software is furnished to do so, provided that the +following conditions are met: + +- Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimers. +- Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimers in + the documentation and/or other materials provided with the + distribution. +- The name of NICTA may not be used to endorse or promote products + derived from this Software without specific prior written permission. + +EXCEPT AS EXPRESSLY STATED IN THIS LICENCE AND TO THE FULL EXTENT +PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS-IS" AND +NICTA MAKES NO REPRESENTATIONS, WARRANTIES OR CONDITIONS OF ANY +KIND, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY +REPRESENTATIONS, WARRANTIES OR CONDITIONS REGARDING THE CONTENTS +OR ACCURACY OF THE SOFTWARE, OR OF TITLE, MERCHANTABILITY, FITNESS +FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, THE ABSENCE OF LATENT +OR OTHER DEFECTS, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR +NOT DISCOVERABLE. + +TO THE FULL EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL +NICTA BE LIABLE ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, +NEGLIGENCE) FOR ANY LOSS OR DAMAGE WHATSOEVER, INCLUDING (WITHOUT +LIMITATION) LOSS OF PRODUCTION OR OPERATION TIME, LOSS, DAMAGE OR +CORRUPTION OF DATA OR RECORDS; OR LOSS OF ANTICIPATED SAVINGS, +OPPORTUNITY, REVENUE, PROFIT OR GOODWILL, OR OTHER ECONOMIC LOSS; +OR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL, PUNITIVE OR +EXEMPLARY DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS LICENCE, +THE SOFTWARE OR THE USE OF THE SOFTWARE, EVEN IF NICTA HAS BEEN +ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +If applicable legislation implies warranties or conditions, or +imposes obligations or liability on NICTA in respect of the Software +that cannot be wholly or partly excluded, restricted or modified, +NICTA's liability is limited, to the full extent permitted by the +applicable legislation, at its option, to: + +a. in the case of goods, any one or more of the following: + i. the replacement of the goods or the supply of equivalent goods; + ii. the repair of the goods; + iii. the payment of the cost of replacing the goods or of acquiring + equivalent goods; + iv. the payment of the cost of having the goods repaired; or +b. in the case of services: + i. the supplying of the services again; or + ii. the payment of the cost of having the services supplied + again. + + +# Links: + +NICTA + http://www.nicta.com.au/ +Darwin + http://developer.apple.com/darwin/ +DNS service discovery and link-local + http://http://zeroconf.org/ + http://http://multicastdns.org/ + http://http://dns-sd.org/ + http://http://dotlocal.org/ |
