问题

we disabled smbv1 in our windows machine and now we can't connect using smb2

we are using commons-vfs2(2.0) and commons-vfs2-sandbox(2.0)

here is my code:

@Test

public void testConnection() throws FileSystemException {

String folder = "\\\\10.0.0.0\\smb";

folder = folder.replaceAll("\\\\", "/");

StringBuilder builder = new StringBuilder(128).append(Protocol.CIFS.getProtocolPrefix()).append(':')

.append(folder);

String fileURI = builder.toString();

System.out.println(fileURI);

FileSystemOptions fsOptions = null;

String password = "mAdmin";

String username = "myPassword";

String domain = "";

StaticUserAuthenticator auth = new StaticUserAuthenticator(domain, username, password);

fsOptions = new FileSystemOptions();

DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(fsOptions, auth);

FileSystemManager manager = VFS.getManager();

FileSystemManager fileSystemManager = manager;

FileObject fileObject = fileSystemManager.resolveFile(fileURI, fsOptions);

boolean result = fileObject.isReadable();

System.out.println(fileURI +" " + result);

}

this is how I disabled smb v1

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 0 -Force

How I enabled SMBV2

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB2 -Type DWORD -Value 1 -Force

in case we are enablying SMB1 it's working

Unfortunately commons-vfs2 does not support the SMBv2 protocol. The only open source implementation currently of an SMBv2 client is SMBJ. Using SMBJ you could connect as follows to your share:

SMBClient client = new SMBClient(SmbConfig.createDefaultConfig());

Connection c = client.connect("10.0.0.0");

Session s = c.authenticate(new AuthenticationContext("myAdmin", "myPassword", "");

DiskShare share = s.connectShare("smb");
