8 | Whenever a user tries to print a document, if he is over his print quota, |
---|
9 | then the job is refused. Depending on <application>PyKota</application>'s |
---|
10 | configuration, especially the <literal>mailto</literal> option, he and/or |
---|
11 | the administrator may eventually receive an email message which explains |
---|
12 | the situation and invites him to solve the problem before being allowed |
---|
13 | to print again. |
---|
14 | </para> |
---|
15 | |
---|
16 | <para> |
---|
17 | However this may not be sufficient, and you may want to warn users who |
---|
18 | have reached their print quota at |
---|
19 | regular intervals, like every day, for example from a <application>cron</application> job. |
---|
20 | </para> |
---|
21 | |
---|
22 | <para> |
---|
23 | This may be useful if the user has reached his print quota, and have received an email message telling him so, |
---|
24 | but then he doesn't print for some days and may forget to fix the problem, by buying more |
---|
25 | paper for example. |
---|
26 | </para> |
---|
27 | |
---|
28 | <para> |
---|
29 | The <command>warnpykota</command> command was written with this in mind. |
---|
30 | If you put this command in your <filename>crontab</filename>, launching it for example |
---|
31 | every day, then you'll be sure that all your users who are above their print quota |
---|
32 | will not forget it ! Of course they may delete the messages without having read them, |
---|
33 | but at least they won't be able to say that they didn't receive them ;-) |
---|
34 | </para> |
---|
35 | |
---|
36 | <para> |
---|
37 | When an user who is not a <application>PyKota</application> administrator launches this command, only him can receive a warning |
---|
38 | message. He can specify a printer name's filter to check his quota only |
---|
39 | on specific printers. If a normal user uses the <literal>--groups</literal> command line |
---|
40 | argument, then for each group he is a member of in the print quota database, each |
---|
41 | group member may receive a warning message. You can take care of this if this |
---|
42 | becomes annoying by forbidding normal users to launch the <command>warnpykota</command> |
---|
43 | command. |
---|
44 | </para> |
---|
45 | |
---|
46 | <para> |
---|
47 | <application>PyKota</application> administrators can pass additionnal user or group names |
---|
48 | (or wildcard filters) to only check the users or groups whose name matches. |
