Richiesta di password per montare condivisione di windows

[Elena2]

Ciao, ho 2 computer con uno windows xp home e l' altro con ubuntu 8.10. Ho messo delle cartelle e la stampante di windows in condivisione perchè linux le veda. Quando mi collego alla rete e navigo all' interno delle cartelle spesso e volentieri non me le vuole montare perchè mi chiede utente e password, ma windows non ha un utente con password. La cosa strana è che se riprovo a voler aprire quella stessa cartella dopo mezz' ora, non mi chiede più niente e mi fa fere le normalissime operazione di copia e incolla file e altro.
C'è un motivo particolare del perchè si comporti così?

Grazie

secondo il mio modesto parere potrebbero essere tante le cause...
però per prima cosa:
hai usato samba o qualche altro programma per configurare la condivisione windows-linux?
se è sì hai inserito nel file di configurazione di samba nome utente e password di ubuntu?

t chiedo questo perchè anche io nei primi periodi avevi di questi problemi dovuti alla mancata o scorretta configurazione di samba..

[Elena2]

Ciao, prima di tutto grazie per la risposta.
Si ho usato samba, ma nel file smb.conf non ho messo le righe utente e password di ubuntu.
Mi sapresti dire in quale sezione dovrei metterle e con quale sintassi?

Grazie in anticipo.

Posta "smb.conf".

[p3t3r]

più chiaro di questi 2 link non saprei essere
configurare samba per avere info specifiche su cm configurarlo, ma sopratutto quest'ultimo condividere file con windows dove, in particolare guardando nella sezione "creazione utente samba" ho risolto i miei problemi.
Questo è l'aiuto che ti posso dare
Seguendo questa wiki della documentazione della comunità si dovrebbe riuscire a fare tutto (o quasi)

[Elena2]

ok grazie provo e vi farò sapere

C'è un'altra cosa da capire, Windows è lentissimo nel riconoscere le reti, a me quello scherzo lo fa senza Samba sia tra pc Win che su sistemi misti lin/Win.
All'inizio Win ti chiede account e password perché non ti riconosce, probabilmente ha la card ethernet in riposo e deve attivarla o comunque il driver che si occupa del protocollo è in standby.
Appena fai la richiesta Win attiva il driver, attiva la card e attende una risposta, l'handshake tra le due card, quella del chiamante e quella di chi risponde, la prima cosa che fa è chiedere chi sei, perché non ti riconosce, poi il sistema lo fa per te.
Sia chiaro io provavo come te a mettere account e password, avevo anche configurato le cartelle condivise con account e password ma nulla, il sistema mi chiedeva comunque i dati più volte e solo dopo un po' mi dava l'accesso.
Il sistema migliore è quello di creare un domino all'interno della rete e lavorare su quello.

Ah Win usa NetBios per parlare tra macchine un protocollo che usava mio nonno il consiglio è di disabilitarlo.

Ho provato ad aggiungere un utente nel server di samba in linux come spiega la guida Condividere i file ubuntu windows.

Ho messo lo stesso utente che uso per entrare in linux con il seguente comando:

sudo smbpasswd -a elena (che sarei io) poi inserisco la password che sarebbe la stessa che uso con il comando sudo, ma quando vado a navigare nella rete e cercare ad aprire una cartella condivisa in windows mi appare la finestra di login e mi chiede utente e password, ho inserito quello appena creato ma il risultato è uguale.
Premetto che il computer che condivide i file ha il sistema operativo windows xp home, e non posso settare permessi per utenti o cartelle, o almeno non ho trovato il modo di farlo nemmeno negli strumenti di amministrazione.

Questo è il mio file smb.conf:

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = MSHOME

# server string is the equivalent of the NT Description field
server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both

# This will prevent nmbd to search for NetBIOS names through DNS.

# What naming service and in what order should we use to resolve host names
# to IP addresses

#### Networking ####

# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes



#### Debugging/Accounting ####

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account

# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for

passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

andandolo semplicemente a confrontare con il mio smb.conf ho trovato due possibili cause:
1:

####### Authentication #######
# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
security = share

dv al posto di share metti user

2:

#======================= Share Definitions =======================
# Un-comment the following (and tweak the other settings below to suit)
# to enable the default home directory shares. This will share each
# user's home directory as \\server\username
; [homes]
; comment = Home Directories
; browseable = no

dv al posto di no metti yes

prova così.

Ciao prima la security era impostato su user e mi dava lo stesso problema, poi per la seconda cosa, cioè il browseable è nella sezione della home directory e io però ho problemi sul fatto che mi chiede la password per vedere i file che condivide windows e non che condivide linux. Credo che il problema sia dato dal fatto che il windows che uso è xp home e non mi permette di impostare alcun permesso agli eventuali utenti, infatti quando nel pc c' era win 2000 e avevo messo i permessi per guest e everyone non avevo problemi.
Grazie lo stesso
