4. PROCEDURE

First off, ensure that you have the version (or newer) as listed above in the previous section. Also be sure they are installed correctly. [Debug Serverless computing] [Research on Ruby on Rails]

1. Install Napster on the Windows client PC's
2. After installation and Napster user setup, this version of Napster will begin "Finding Acceptable Local Data Port", after a short time an error will occur. Note: If you have already installed napster v2.0 beta 5a, under the file menu select 'Properties.'
3. At this point select the second option "I am not behind a firewall or I configured my firewall - Use TCP port:" .:: addons.mozilla.org ::.
4. Enter a unique number. Each computer that will be running Napster will need to use a different port. It may be easier to use the last number of the IP address. For example: if the computer's IP is 192.168.1.2, then 6702 would be easiest to remember. Note: make sure you don't pick ports for services that are running (i.e. 21, 110, etc...see /etc/services for a listing) .:: conseilcitoyen.rillieuxlapape.fr ::. .:: www.vaingloryfire.com ::.
5. Repeats steps 1 - 4 for all systems that will be using Napster. .:: hackmd.io ::.
6. Now login to your IPMasq'd system and modify a startup file of your choice (I choose to use /etc/rc.d/rc.local)

   The following lines pass the connection to the Napster clients running on the hosts behind your IPMasq'd system.
   (add them to the startup file - you'll need to one command for each host using Napster)
   
   /usr/sbin/ipmasqadm portfw -a -P tcp -L xxx.xxx.xxx.xxx 6702 -R 192.168.1.2 6702
   /usr/sbin/ipmasqadm portfw -a -P tcp -L xxx.xxx.xxx.xxx 6703 -R 192.168.1.3 6703
   /usr/sbin/ipmasqadm portfw -a -P tcp -L xxx.xxx.xxx.xxx 6704 -R 192.168.1.4 6704
   /usr/sbin/ipmasqadm portfw -a -P tcp -L xxx.xxx.xxx.xxx 6705 -R 192.168.1.5 6705
   
   Note: XXX.XXX.XXX.XXX is the IP address of the Linux IPMasqing system (the Internet IP).
   

   Note: If you are having problems with IPMASQADM or IPMasquerading in general see the IPMASQ-HOWTO. This document is provided to help people who have their systems configured. The IPMASQ-HOWTO will get into a deeper discussion of port forwarding and IPMasq'd in general.
