| | 11 | First you have to determine which machine will be the <application>PyKota</application> |
| | 12 | <glossaryterm>Storage Server</glossaryterm>. The Storage Server is the host responsible |
| | 13 | for keeping a centralized database of print usage for all your printers, users and groups. |
| | 14 | </para> |
| | 15 | |
| | 16 | <para> |
| | 17 | Then you have to list all the <glossaryterm>Print Servers</glossaryterm> for which |
| | 18 | you plan to use <glossaryterm>print quota</glossaryterm> facilities. |
| | 19 | </para> |
| | 20 | |
| | 21 | <para> |
| | 22 | Now we will see what has to be done on all those servers. |

| | 25 | <para> |
| | 26 | Of course, depending on the size of your network, you may very well |
| | 27 | use the same machine as both a Print Server and a Storage Server. |
| | 28 | This is especially the case if you've got only one server. |

| | 35 | |
| | 36 | <para> |
| | 37 | Depending on <application>PyKota</application>'s version number, different |
| | 38 | types of storage backends may be supported, so we will see for each one of |
| | 39 | them how to configure it. |

| | 45 | <para> |
| | 46 | <application>PostgreSQL</application> is an <glossaryterm>Object Relationnal DataBase |
| | 47 | Management System</glossaryterm> distributed under a <glossaryterm>Free Software</glossaryterm> |
| | 48 | license from the |
| | 49 | <ulink url="http://www.postgresql.org">http://www.postgresql.org</ulink> |
| | 50 | web site. It certainely is the free <acronym>RDBMS</acronym> which has the most advanced |
| | 51 | features, and is widely used all over the world. |
| | 52 | </para> |
| | 53 | |
| | 54 | <para> |
| | 55 | To configure your Storage Server, you must have PostgreSQL already working. |
| | 56 | The complete installation of <application>PostgreSQL</application> is not covered by |
| | 57 | the present manual, please refer to your system's documentation or to |
| | 58 | <ulink url="http://www.postgresql.org">http://www.postgresql.org</ulink> for |
| | 59 | details. |
| | 60 | </para> |
| | 61 | |
| | 62 | <para> |
| | 63 | One thing you have to check, though, is that every Print Server on which you |
| | 64 | want to install the print quota mechanism must be able to connect to the |
| | 65 | <application>PostgreSQL</application> server. In the default installation of |
| | 66 | <application>PostgreSQL</application> this may not be the case for security reasons, except if both |
| | 67 | servers are in fact the same machine. In any case, it is recommended that you |
| | 68 | check the <filename>/etc/postgresql/pg_hba.conf</filename> and modify it if |
| | 69 | needed. This file is self documented and its modification is straightforward. |
| | 70 | <tip> |

| | 72 | <para> |
| | 73 | Don't forget to restart <application>PostgreSQL</application> if you modify |
| | 74 | any of its configuration files, in order for the changes to take effect. |

| | 79 | <para> |
| | 80 | Be careful, you may be unable to connect from a Print Server to the <application>PostgreSQL</application> |
| | 81 | server even if the configuration is correct. Sometimes your connections may be blocked by |
| | 82 | one or more network firewalls along the route from one machine to the other. If this |
| | 83 | is the case, then the best thing you can do is to ask your <glossaryterm>Network Administrator</glossaryterm> |
| | 84 | to not filter the IP port used by <application>PostgreSQL</application>, which is |
| | 85 | usually port 5432/tcp. |
| | 86 | <tip> |
| | 87 | <title>Tip</title> |
| | 88 | <para> |
| | 89 | The TCP/IP network port used by PostgreSQL may be different. When in doubt, ask your |
| | 90 | <glossaryterm>System Administrator</glossaryterm> for the correct value. |
