Ubuntu 12.04 – Configurando Samba (3.6.3)


Olá,

Hoje decidi formar meu servidor de casa e quando "terminei" de configurar o samba eu tive alguns problemas.

Quando eu estava tentando conectar ao meu Ubuntu 12.04 server, eu recebia a seguinte mensagem: "Failed to Retrieve Share List from Server"

Para resolver eu adicionei dentro do arquivo de configuração /etc/samba/smb.conf na seção [globals] o seguinte:

name resolve order = bcast host

Eu fiz isso no meu computador também. (Mas não tenho certeza se isso é necessário, eu acredito que não). Reiniciei o servidor e esta funcionando.

Dentro do meus arquivos de logs /var/log/samba/log.XXXX eu estava recebendo diversas mensagens de smb_panic:

[2013/03/07 22:13:43.607536, 0] lib/util.c:1122(smb_panic) smb_panic(): calling panic action [/usr/share/samba/panic-action 1928]

(Novamente, eu não tenho certeza que essa mensagem esta exclusivamente relacionada com esse problema e acredito que não, mas não custa nada deixar claro que eu também tinha ela.)

Outra mensagem que eu estava vendo quando utilizava smbclient -L SERVER era:

NT_STATUS_PIPE_BROKEN

Se você deseja ver todo o meu smb.conf continue lendo!

O meu arquivo de configurações é uma pasta Compartilhados que é somente leitura mas que qualquer um pode acessar (guest) e a outra é Writable, onde todos podem escrever. (guest) Ou seja, minha configuração não utiliza de autenticação para os meus compartilhamentos.

Se eu lembrar de mais algum detalhe eu aviso vocês.

Thanks,
Matheus

PS: Eu acredito que este não seja um problema exclusivo do Ubuntu 12.04 ou 12.10 mas sim alguma modificação do Samba

Just some small changes from default file, but to solve this problem took me sometime.

#======================= Global Settings =======================

[global]

guest account = nobody
## Browsing/Identification ###

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

# 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
; wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
dns proxy = no

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

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# 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 ####

# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d

####### 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 = user

# You may wish to use password encryption. See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.
encrypt passwords = true

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.
passdb backend = tdbsam

obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan < for
# sending the correct chat script for the passwd program in Debian Sarge).
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
# 'passwd program'. The default is 'no'.
pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
map to guest = bad user

########## Domains ###########

# Is this machine able to authenticate users. Both PDC and BDC
# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no
#
; domain logons = yes
#
# The following setting only takes effect if 'domain logons' is set
# It specifies the location of the user's profile directory
# from the client point of view)
# The following required a [profiles] share to be setup on the
# samba server (see below)
; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
# logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
; logon drive = H:
# logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the
# SAMR RPC pipe.
# The following assumes a "machines" group exists on the system
; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.
; add group script = /usr/sbin/addgroup --force-badname %g

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
# load printers = yes

# lpr(ng) printing. You may wish to override the location of the
# printcap file
; printing = bsd
; printcap name = /etc/printcap

# CUPS printing. See also the cupsaddsmb(8) manpage in the
# cupsys-client package.
; printing = cups
; printcap name = cups

############ Misc ############

# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting

; message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s; rm %s' &

# Domain Master specifies Samba to be the Domain Master Browser. If this

# must set this to 'no'; otherwise, the default behavior is recommended.

# for something else.)
; idmap uid = 10000-20000
; idmap gid = 10000-20000

# The following was the default behaviour in sarge,
