Compartilhamento Samba Webmin

[thiagoduarteoliveira]

Boa Tarde a Todos 

Gente tou com um problema talvez um pouco comum para iniciantes Linux e o seguinte:
Instalei o Ubuntu 11.04 normalmente para usa-lo como servidor depois instalei o Webmin sem nenhum erro apos instalar o Webmin instalei alguns modulos (Samba , Squid e servidor Apache) eu tou a 1 semana pesquisando só sobre o Samba e hoje foi que consegui finalmente fazer a pasta compartilhada finalmente funcionar, ai entao apaguei o compartilhamento apos funcionar e tentei refaze-lo (Para aprender) ja que não podia deixar rodando depois de catucar para tudo quanto é canto, minha duvida e a seguinte: agora apos fazer compartilhamento via Webmin ele aparece quando tento acessar de uma outra maquina mais ao tentar abrir a pasta ele diz que a maquina nao tem permissao para acessar eu queria dar acesso total aos usuarios sobre essa pasta.
Nao sei se e permitido colocar o arquivo de Configuração aqui, mais se for proibido e só avisar que tiro na mesma hora, pois estou querendo saber o que esta errado agora para nao conseguir acessar nada nesse compartilhamento.


# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field

# 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.

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

#### 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

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

# 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.

# Do something sensible when Samba crashes: mail the admin a backtrace


####### 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.

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


# 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.

# 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
# sending the correct chat script for the passwd program in Debian Sarge).

# 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'.

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

Experimenta passar teu arquivo de configuração pelo programa testparm, pra validar os comandos.

Sobre a configuração que vc postou, que eu saiba não tem problema nenhum, mas se vc puder tirar antes os comentários ajuda pra quem for ler. Uma dica é pegar a saída do próprio comando testparm, que já faz exatamente isso (tirar os comentários e mostrar todas as configurações ativas).

Boa noite thiagoduarteoliveira,

Tudo bem?

O seu arquivo está mexido e baseado no original. Mas como está fazendo uso do webmin, vc pode selecionar todo o conteúdo e copiar no lugar dele o conteúdo abaixo:

[global]
#   GERAL
#   workgroup = HARDWARE
   netbios name = HARDWARE
   server string = SAMBA PDC

#   GRUPO DE TRABALHO
   guest account = root
   password server = none
   local master = no
   guest ok = yes
   os level = 20
   domain master = no
   security = share

[arquivos]
   comment = arquivos directory
   path = /var/samba/arquivos
   writable = yes
#   valid users = +arquivos
#   invalid users = +admin
#   vfs object = recycle
#   recycle:repository = lixeira
#   recycle:keeptree = yes
   preferred master = no

Neste exmplo de smb.conf é voltado para funcionar como grupo de trabalho. e os campos de valid users ou invalid users poderá ser usado somente um de cada vez, ou seja, se for usar o valid users poderá colocar o ip que terá a permissão de uso do diretório e o que não terá acesso ao diretório deverá  conter EXCEPT e o endereço ip que não terá acesso ao diretório. veja que no compartilhamento arquivo ele existirá, mas se não criar o diretório onde está indicado no path não terá o diretório efetivamente funcionando, ok? o melhor jeito de se aprender é na mão, pois com o uso do webmin  direto não saberá com facilidade onde errou, portanto, faça um estudo paralelo no shell e não só no webmin, ok?

Um abraço.

Bicalho, eu sempre me bato contra o uso do "security=share". Esse modo de trabalho é inseguro, obsoleto, e principalmente, não funciona da maneira que as pessoas esperam.

[bfbicalho]

Zekkerj,

Então como posso melhorar ele?

Obrigado pelo alerta.

[zekkerj]

Não usando. Cadastrar os usuários e liberar o acesso conforme a necessidade.

[bfbicalho]

Ou seja, usar ele como PDC, certo?

[thiagoduarteoliveira]

Muito Obrigado gente, ao passar o arquivo pelo testparm ele deu uma limpada depois fui dentro do proprio editor do Webmin e colei o arquivo limpo ao acessar a pasta ele pediu o nome o usuario e a senha preenchendo como estava fazendo antes ele PaSSOU .
Mais uma vez gente muito obrigado pela ajuda pois estava batendo cabeça com esse compartilhamento a uma semana, estou so pensando agora no Squid rssss que vou ter que configurar tambem  mais isso, ja é outro livro.
Abraço a todos.

[bfbicalho]

Bom que resolveu. mas o mais importante e seguir com calma em relação ao squid, pois além dele tem que ter um firewall funcionando junto. uma vez instalado o squid o seu gerenciamento não é difícil, mas basta ter atenção.

Um abraço.

[zekkerj]

Ou seja, usar ele como PDC, certo?

Não necessariamente... Pra fazer do Samba um PDC precisa mais coisas do que só passá-lo pro modo "security=user".

[bfbicalho]

entendi, vou modificar para o user a segurança dele.

Obrigado.
