Windows 10 acessando compartilhamento do Samba 4 no Debian 11 [RESOLVIDO]

Tenho um sistema em Java com o DB PostgreSQL 12 que acessa dado arquivo.xml de um diretório com vários outros para montar determinado formulário de manipulação de uma tabela específica do DB.
O sistema funciona perfeito no Debian 11, Ubuntu 18 dentre outros. Tudo com o compartilhamento funcional com Samba 4.
No Windows 10, que também acessa compartilhamento Samba, a mesma operação só acessa sempre o último arquivo do diretório.
Testei várias configurações e o problema persiste.
Alguém tem alguma ideia de como resolver o problema? Agradeço antecipadamente.

4. Problema do protocolo quanto à vinculação ao sistema de arquivos do Windows 10

Enviado em 18/09/2021 - 11:46h

Fiz várias e infrutíferas tentativas. No Windows habilitei nas suas configurações o protocolo SMB, e nada.
Testei com outras máquinas e funcionou perfeitamente com Debian, Ubuntu e iOS. Somente no Windows 10 não funciona. Não testei com outros windows porque não os tenho mais.
Repetindo o problema:
1. Tenho um sistema no Linux que possui um diretório /forms com vários arquivos .xml que servem para montar uma tela de forma automática. No Linux e iOS funciona bem, mas no Windows 10, dos vários arquivos existentes, ele somente acessa o último. É como ser o sistema não reconhecesse a lista de diretórios (No windows ele lista os arquivos perfeitamente no Gerenciador de arquivos e no prompt);
2. Já mudei a versão do Java desde a 12 até agora na 16 e o problema persiste, somente no Windows 10.
3. Tenho também um diretório /sqls on existem vários arquivos .xml com comandos sql específicos. Apresenta também o mesmo problema, somente no acesso de chamada pega somente o último arquivo. Exemplo fonte Java:
...
String w_arquivo = fileGetFill("type=mid&file=1");
...
public static String fileGetFull(String w_options){
String w = "";
String w_dir = lib.config.DIR_FORMS; // Diretório dos arquivos .xml dos FORMS.
String w_type= lib.sql.sql_field(w_options,"type").trim().toLowerCase();
if (w_type.equals("") || w_type.equals("form")) w_type="mid";
if (w_type.equals("sql")) w_dir = lib.config.DIR_SQLS; // Diretório dos arquivos .xml dos SQLS.
String w_file= lib.sql.sql_field(w_options,"file").trim().replace("./",""); // Normalização
File dirList = new File(w_dir);
File listFile[] = dirList.listFiles();
try {
for (int w_i=0; w_i < listFile.length; w_i++ ) {
//******************************************************************
w = ""+listFile[w_i].toString().replace("./","");
//******************************************************************
if ( w.contains(w_file)) { // Sai ao encontrar o arquivo solicitado.
break;
}
}
}
} catch (Exception e){
w = "";
lib.util.erro("Error. File="+w_file+". "+e.getMessage());
}
return w;
}
...
Há alguma coisa a mais que possa tentar?

Essas configurações abaixo estão no [homes].
Este homes é o compartilhamento para o Windows?

# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.

create mask = 0700

# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.

directory mask = 0700


O [satis] é o compartilhamento do sistema que as máquinas Windows conseguem acessar somente o último arquivo?

Tente criar de teste um compartilhamento somente para máquinas Windows de acordo com o exemplo abaixo alterando/acrescentando no Global:

[global]
workgroup = SAME_WORKGROUP_AS_CONFIGURED_IN_WINDOWS
server string = Samba Server %v
netbios name = HOST_NAME_OF_YOUR_LINUX_MACHINE_ON_NETWORK
security = user
map to guest = bad user
dns proxy = no

[yourshare]
path = /PATH/TO/YOURSHARE
valid users = YOUR_WINDOWS_USER_NAME
browsable = yes
writeable = yes
guest ok = no
read only = no
directory mask = 0775
create mask = 0775

Verifique também se não é o firewall ou o Selinux (se tiver).
E verifique as permissões das pastas e arquivos, pois as permissões do samba são diferentes das permissões do sistema e elas devem bater umas com as outras.

6. Problema resolvido

Prezado colega, primeiramente obrigado pela valorosa contribuição. Finalmente consegui resolver o problema que, após várias tentativas inerentes ao uso do sistema de arquivos e configuração do Samba, persistindo o problema, resolvi ir por outros caminhos e resolvi da seguinte forma:
1. Usei 2 computadores, um com Windows 10 e outro com Linux Debian 11;
2. Acessei o programa em Java em ambos usando o Netbeans 12.5;
3. Coloquei um "trace" em locais específicos do programa e avaliei nas duas plataformas. Resultado no fonte em Java 16_0_2:
...
String w_file= lib.sql.sql_field(w_options,"file"); // Aparece algo em torno de /teste/teste,xml em Linux e Windows 10;
String w_fs = System.getProperty("file.separator"); // Pega o separador de arquivos usado pelo sistema operacional.
File dirList = new File("/teste"); // Lista diretório /teste padrão.
File listFile[] = dirList.listFiles(); // Acessa os arquivos do diretório /teste com comandos implícitos da linguagem,
// Os arquivos aparecem como "/teste/teste.xml" no Linux e Windows 10.
w = listFile[w_i].toString(); // No Linux o separador de arquivos aparece como "/" e no Windows 10 como "\".
// Normalizei então o separador de arquivos, visto que no Linux (/) funciona e no Windows 10 não (\):
...
for (int w_i=0; w_i < listFile.length; w_i++ ) {
w = w.replace(w_fs, "/"); // Padronizei tudo como "/".
if (w.contains(w_file)){
System.out.println("File "+w_file+" - w = "+w+" > " );
if ( lib.files.isFile(w,"") ) {
// System.out.println(" Found File "+w_i+" "+" "+w_ud+": "+w_file+" - "+w);
break;
}
}
}
...
Ou seja agora os arquivos são comparados com "/teste/teste.xml" e "/teste.xml" sempre, fazendo com que a função funcionasse, e não "/teste/teste.xml" e "\teste.xml", onde "\teste.xml" jamais estaria contido em "/teste/teste.xml", fazendo com que a função ocasionasse problema.
Em Resumo:
1. Sistema de arquivos Samba 4 funcionando perfeitamente no Debian 10;
2. Acesso aos compartilhamentos do Samba pelo Windows 10 funcionando perfeitamente;
3. Java apresenta esse detalhe que só foi percebido com o "trace" e uma simples alteração no separador de arquivos resolveu.
4. Sistema funcionando perfeitamente em todas as plataformas testadas.

Obrigado pela ajuda. Deixo aqui minha experiência para prováveis futuros problemas semelhantes.

Por isso ele só acessava o último arquivo, ele não conseguia "subir" no caminho porque não reconhecia o separador.
