BeitragVerfasst am: 07. Sep 2002 18:14   Titel: CUPS nochmal ganz von vorne...

Hallo ihr alle - nicht nur max (DANKE nochmal für deine Mühe!!),

nachdem ich erfolglos versucht habe, meine CUPS-Drucker vernünftig zum Laufen zu bringen bzw. mit "kups" verwaltet laufen zu lassen, habe ich gerade nochmal ganz von vorne angefangen: CUPS deinstalliert und wieder installiert.

Die gute Nachricht: prinzipiell läuft das Ganze, ich kann drucken und auch die Drucker verwalten. Ich habe ein bisschen "kups" im Verdacht, Teil meiner bisherigen Probleme gewesen zu sein, deswegen nutze ich jetzt das CUPS-Web-Interface - ist auch gut. Allerdings besteht jetzt wieder das Problem, weswegen das ganze Übel hier erst richtig angefangen hat: man kann nur als "root" etwas ändern, z. B. Druckaufträge löschen. Das soll bei mir aber jeder Benutzer können. Max hatte mir gesagt, ich müsste in der cupsd.conf die Zeile "SystemGroup sys" durch "SystemGroup users" ersetzen. Das habe ich jetzt getan, es hat aber nicht geholfen.

Weiß hier irgendwer weiter?

So, ich bin wieder da.
Der Eintrag
SystemGroup users
erlaubt allen Benutzern die Mitglied der Gruppe sind die Drucker zu administrieren. Glaub mir!
Teste es folgendermaßen:
- Starte über Browser das Webinterface (http://localhost:631) als normaler Benutzer.
- Versuche einen Drucker zu stoppen
- Als UserId/Passwort gib die des normalen Benutzers ein -> wird nicht funktionieren (nur wennst root+Passwort eingibst funktioniert es).
- Schließe den Browser
- Stoppe cupsd
- Ändere in cupsd.conf "SystemGroup sys" auf "SystemGroup users"
- Starte cupsd
- So, starte nun das Webinerface neu und versuche als normaler Benutzer den Drucker zu stoppen/starten => wird funktionieren!

Ich hoffe das war es jetzt!

Vielleicht bist Du nur verwirrt dass eine Abfrage für UserId + Passwort kommt. Dort musst Du dann die UserId und das Passwort des "normalen" Benutzers eingaben (sofern "Systemgroup users" definiert ist). Die Abfrage UserId/Passwort kommt immer, was aber nicht heisst dass Du nur root dort eingeben kannst.

>Ich hoffe das war es jetzt!<

Ähm... ich fürchte nicht... Ich würde Dir auch WIRKLICH gerne glauben (und dich damit gleichzeitig von meinen nervigen Fragen befreien), aber leider funktioniert die Sache nunmal nicht. Zumindest nicht heute, d. h. nachdem ich CUPS wieder neu installiert habe. Gestern war das anders, WENN da etwas funktionierte, dann bei allen Benutzern.
Aber mit dem neu installierten CUPS...
Ich habe genau das gemacht, was du gesagt hast, und ich habe natürlich auch versucht, meinen normalen Benutzernamen+Kennwort einzugeben, aber dann kommt immer die Meldung "leider war der Authentifizierungsversuch nicht erfolgreich". Nur wenn ich "root"+Kennwort eingebe, klappt's.
Ich frage mich, ob vielleicht bei dem De- und Neuinstallieren irgendwas mit der config-Datei durcheinander gekommen ist, so dass CUPS z. B. eine andere config benutzt als die, in der ich da rumändere. Da gibt es nämlich nicht nur "cupsd.conf", sondern auch noch "cupsd.conf.O" und "cupsd.conf.rpmsave". Außerdem sieht auch die normale cupsd.conf ganz anders aus als vor der Neuinstallation, da sind jetzt zwischen den eigentlichen Skriptzeilen immer noch jede Menge Erklärungen. Vielleicht ist es am einfachsten, wenn ich dir alle drei Dateien schicke (auch wenn das bedeutet, dass da jetzt gleich wieder so'ne Riesenlatte kommt):

# BrowseAddress
#
# Specifies a broadcast address to be used. By
# default browsing information is broadcast to all active interfaces.
#
# Note: HP-UX 10.20 and earlier do not properly handle broadcast unless

# ImplicitClasses
#
# Whether or not to use implicit classes.
#
# Printer classes can be specified explicitly in the classes.conf
# file, implicitly based upon the printers available on the LAN, or
# both.
#
# When ImplicitClasses is On, printers on the LAN with the same name

# queue.
#
# Enabled by default.
#
#ImplicitClasses Off

# ImplicitAnyClasses
#
# Whether or not to create AnyPrinter implicit
# classes.
#
# When ImplicitAnyClasses is On and a local queue of the same name
# exists, e.g. "printer", "printer@server1", "printer@server1", then
# an implicit class called "Anyprinter" is created instead.
#
# When ImplicitAnyClasses is Off, implicit classes are not created
# when there is a local queue of the same name.
#
# Disabled by default.
#
#ImplicitAnyCLasses Off

# HideImplicitMembers
#
# Whether or not to show the members of an
# implicit class.
#
# When HideImplicitMembers is On, any remote printers that are

# ImplicitClasses
#
# Whether or not to use implicit classes.
#
# Printer classes can be specified explicitly in the classes.conf
# file, implicitly based upon the printers available on the LAN, or
# both.
#
# When ImplicitClasses is On, printers on the LAN with the same name
# (e.g. Acme-LaserPrint-1000) will be put into a class with the same

# queue.
#
# Enabled by default.
#
#ImplicitClasses Off

ImplicitClasses On

# ImplicitAnyClasses
#
# Whether or not to create AnyPrinter implicit
# classes.
#
# When ImplicitAnyClasses is On and a local queue of the same name
# exists, e.g. "printer", "printer@server1", "printer@server1", then
# an implicit class called "Anyprinter" is created instead.
#
# When ImplicitAnyClasses is Off, implicit classes are not created
# when there is a local queue of the same name.
#
# Disabled by default.
#
#ImplicitAnyCLasses Off

ImplicitAnyClasses Off

# HideImplicitMembers
#
# Whether or not to show the members of an
# implicit class.
#
# When HideImplicitMembers is On, any remote printers that are
# part of an implicit class are hidden from the user, who will
# then only see a single queue even though many queues will be
# supporting the implicit class.
#
# Enabled by default.
#
#HideImplicitMembers On

HideImplicitMembers Yes

# BrowseShortNames
#
# Whether or not to use "short" names for remote printers

Hmm, und das "root"-Problem ist anscheinend auch nicht ganz das einzige:

Ich wollte gerade als "root" die Konfiguration eines Druckers ändern. Beim Klicken auf "Conifgure printer" kamen auch die Konfigurationseinstellungen, aber wenn ich dann auf "Continue" geklickt habe, kam

"Beim Laden von http://localhost:631/admin ist folgender Fehler aufgetreten:


Unknown Authorization method!"

Also langsam glaube ich, dieses blöde CUPS will einfach nicht für mich drucken!!

Ich habe nun Deine cupsd.conf (die 1., die beiden anderen sind nur Backups) bei mir in Verwendung und nur den Parameter "SystemGrups users" konfiguriert und es funktioniert (Webinterface - Printers - Modify Printers, Start/Stop, Cancel Jobs,...).
Nach Änderungen an der cupsd.conf stoppst und startest den cupsd schon neu!?

Was Du noch testen solltest (zugegeben, ist ein schwacher Versuch!): Schau mal in der Datei /etc/group nach, ob bei der Gruppe users Deine Benutzer eingetragen sind. Sollte so aussehen (Beispiel: 2 Benutzer namens max und mimi existieren):
users:x:100:max,mimi
Wenn nicht, dann trage sie dort ein (mit Komma getrennt). Deine Benutzer natürlich und max und mimi!
Restart cupsd und dann testen.


Sonst fällt mir im Moment auch nicht mehr viel ein wieso es bei Dir nicht funktionert. Aber eines probiere schon noch:
Lege eine neue Gruppe an (z.B. "prtadmin") und trage den normalen Benutzer als Mitglied dieser Gruppe ein. In der cupsd.conf verwende dann "SystemGroup prtadmin".

BeitragVerfasst am: 08. Sep 2002 10:07   Titel: Re: CUPS nochmal ganz von vorne...

Tja, dann sind wir wohl mit unserem Latein am Ende...

Ja, ich habe cupsd immer brav gestoppt und neu gestartet, ja, ich hatte schon nachgesehen, ob auch tatsächlich alle Benutzer in der Gruppe "users" sind, und ja, ich war sogar selbst (!) schon auf die Idee gekommen, eine neue Gruppe anzulegen und bei "SystemGroup" einzutragen. Wie Du in meiner config sehen kannst, heißt die bei mir "printer".

Also wenn Dir jetzt wirklich nichts mehr einfällt (was mich nicht wundern würde, schließlich hast Du mich schon eine GANZE MENGE ausprobieren lassen): Trotzdem nochmal DANKE!! Du hast Dir echt wahnsinnig Mühe mit mir gegeben!
Und ein bisschen weiter als am Anfang bin ich jetzt ja auch: die Drucker laufen, immerhin kann ich als "root" das meiste machen (z. B. Drucker starten/anhalten, Druckaufträge löschen...) - und außerdem habe ich ein bisschen mehr Einblick in mein System bekommen und festgestellt, dass es hier echt nette Leute gibt, die viele Stunden ihrer kostbaren Zeit opfern, um einem Computerdeppen wie mir zu helfen

Hmm, man soll ja den Tag nicht vor dem Abend loben, deshalb werde ich jetzt nicht in Jubel ausbrechen, aber:

Ich glaub', ich hab's!!

Und zwar hab' ich jetzt nochmal in Ruhe die ganze cupsd.conf samt Erklärungen durchgesehen und den Eintrag "AuthClass System" in "AuthClass User" geändert. Außerdem habe ich gesehen, dass in der Datei client.conf nicht nur ein Eintrag "Encryption" war, sondern gleich vier, und zwar jeder mit einem anderen Parameter. Das sah dann ungefähr so aus:

Encryption Always
Encryption Never
Encryption Required
Encryption IfRequested

Das schien mir doch ziemlich unsinnig, deshalb habe ich alle Einträge außer "Encryption IfRequested" gelöscht.

Tja, und ich weiß nicht, an welcher Maßnahme es nun liegt, aber es sieht so aus, als würde jetzt alles so funktionieren, wie ich mir das vorstelle! Sogar nach einem Neustart des Rechners!
Sollten die Probleme damit wirklich gelöst sein, muss ich sagen: Nochmal EXTRA DANKE, Max!! Diesmal nochmal besonders für den "Einblick in mein System".

Aber ich wollte doch eigentlich nicht in Jubel ausbrechen, sonst bestraft mich CUPS bestimmt sofort.
