Titolo: Re: [SAMBA] Serve visibile ma non accedibile

 presenti su Samba.
Ma se la directory e' aperta a tutti non e' un problema se l'utente non e'
presente. Con FC2 avevo fatto uguale e il tutto funzionava tranquillamente.
Praticamente la directory deve essere una directory dove tutti possono
leggere e scrivere a piacere, non solo alcuni utenti!
Grazie Alan

presente.
Questo non è detto: puoi postare smb.conf?

Inoltre bisognerebbe controllare a livello di sistema come è messo
l'account che Samba utilizza come guest.


Non funziona, mi sai dire per caso che utente dovrei impostare come guest?
Io avevo impostato prima        guest user = nobody
La directory da me creata e' stata creata cosi' da root:
mkdir /samba
chmod 777 /samba



nobody è l'utente guest di default di samba, non occorre impostarlo
esplicitamente.
piuttosto bisogna controllare che esista come account di sistema
fai
# cat /etc/passwd | grep nobody
deve restituirti una riga con i dati di nobody
altrimenti devi creare tu un utente guest, e, se diverso da nobody,
devi aggiungerlo anche a smbpasswd e indicarlo esplicitamente in
smb.conf

Il risultato e' questo:
nobody:x:99:99:Nobody:/:/sbin/nologin
Pero' non capisco perche' non si possa nemmeno vedere nel browsing della
rete



testparm ti da esito positivo?
controlla che samba parta regolarmente
fai 
ps -aux | grep mbd
ci sono linee sia per smbd che per nmbd?
che dicono smbd.log e nmbd.log?

Che windows e'?
La macchina ha un nome netbios riconosciuto dal server samba?
Ha un qualche firewall attivo?

 Ha un qualche firewall attivo?
Nessun firewall nella rete interna, a meno che non sia attivo di default in
installazione della Fedora Core 3. E cmq le stesse configurazioni sono state
utilizzate con la Fedora Core 2 senza nessun problema.
Ciao

 utilizzate con la Fedora Core 2 senza nessun problema.
confermi che il firewall di windows sia inattivo oppure abbia settata

Se intendi quella porcata che attivi nelle proprieta' della connessione di

Ciao Alan

 sulla macchina windows.
L'ho fatto, ma i PC Windows lo vedono anche se non possono accedere alle
risorse condivise e il server samba non riesce a vedere le risorse windows
condivise dagli altri se non con il comando smbclient ed eventuamente se le
monto come directory.

ti dovrebbe mancare nella configurazione del firewall l'indicazione di eth0
come periferica fidata. prova a vedere.
altrimenti prova a disabilitare il firewall oppure apri le porte
