[MontelLUG] Samba e connessioni aleatorie

[Daneel Olivaw]

Salve lista!
Il nuovo server dati sta funzionando; io speravo bene, ma come al
solito a qualcuno non va che tutto fili liscio...

Il problema è questo: le segretarie si collegano agli
applicativi/files/cartelle nel server per lavorare, ma ogni pochi
minuti si ritrovano con un errore che fa pensare alla caduta della
connessione. Però se chiudono l'applicazione/cartella/quello_che_è e
riaprono, tutto rifunziona di nuovo.

Un po' di log (scusate la lunghezza '^_^); quello che segue è
l'estratto del log di samba per l'utente "silvia" sulla macchina
"pcsilvia", le è partito anche un file...

Ci capite qualcosa? Ci possono essere problemi su samba, o è il client
che dà i numeri? La cosa strana è che la collega al suo fianco riporta
le stesse cose, mentre un altro dice che a lui funziona tutto... Ah, i
client sono winxp

Oh, dimenticavo, la versione di samba:

isaac:/var/log/samba# dpkg -l | grep samba
ii  libcrypt-smbhash-perl    0.12-1                          generate
LM/NT hash of a password for samba
ii  samba                    3.0.24-6etch4                   a

Grassie e a presto :-)
