Samba配置用户密码方法详解

阅读更多关于 Samba配置用户密码方法详解

Samba是一个开放源代码/自由软件套件，自1992年以来，它已为各种SMB / CIFS客户端（包括众多版本的Microsoft Windows操作系统）提供文件和打印服务。 Samba有三种后台：smbpasswd、tdbsam和ldapsam！smbpasswd较为常用！ 1. smbpasswd 略。。。（待验证补充） 2.tdbsam 该方式则是使用一个数据库文件来建立用户数据库。数据库文件叫passdb.tdb，默认在/etc/samba目录下。passdb.tdb 用户数据库可以使用smbpasswd –a来建立Samba用户，不过要建立的Samba用户必须先是系统用户。我们也可以使用pdbedit命令来建立Samba账户并由其pdbedit管理常用参数： pdbedit -a username：新建Samba账户。 pdbedit -r username：修改Samba账户。 pdbedit -x username：删除Samba账户。 pdbedit -L：列出Samba用户列表，读取passdb.tdb数据库文件。 pdbedit -Lv：列出Samba用户列表详细信息。 pdbedit -c “[D]” -u username：暂停该Samba用户账号。 pdbedit -c “[]” -u username：恢复该Samba用户账号。 3. ldapsam

Reasoning with Fuseki, TDB and named graphs?

阅读更多关于 Reasoning with Fuseki, TDB and named graphs?

问题 I'm serving a dataset containing 10-20 named graphs from a TDB dataset in Fuseki 2. I'd like to use a reasoner to do inference on my data. The behaviour I'd like to see is that triples inferred within each graph should appear within those graphs (although it would be fine if the triples appear in the default graph too). Is there a simple way of configuring this? I haven't found any configuration examples that match what I am trying to do. The configuration I've tried is very similar to the

问题 I am currently writing some code in Java, using Jena and TDB -- on a Windows 7. I want to be able to load a (large) .trig file into TDB Dataset so that querying is a bit faster. The code that I currently have is: Dataset dataset = TDBFactory.createDataset(directoryPath); Model tdb = dataset.getDefaultModel(); RDFDataMgr.read(tdb, inputFilePath); try { String theQuery = readFile(testQueryPath, Charset.defaultCharset()); Query query = QueryFactory.create(theQuery); QueryExecution qe =

How I can use Fuseki with Jena TDB

阅读更多关于 How I can use Fuseki with Jena TDB

问题 I have a question for you. I have a triplestore "Jena TDB" and I have read that I can set up a SPARQL endpoint for locally stored RDF data. In particular, I saw that in the literature together with Jena TDB is used Fuseki. I loaded my files rdf in Jena TDB in this way: public void store(){ String directory = "C:\\tdb"; String source = "C:\\file1.rdf"; String source1 = "C:\\file2.rdf"; Dataset dataset = openTDB(directory); Model tdb = loadModel(source, dataset); dataset.addNamedModel("File1",
