Java有很多开源的项目，用java求连接FTP、数据库、SVN之类的其实都很方便。既然可以很easy的求连接，那么是不是可以简单的改下弄给爆破呢？于是默默的新建了一个名叫“@z7y”的项目......本文只提供方法不提供具体工具实现！

Java连接SSH：

package org.javaweb.util;
import java.io.IOException;
import ch.ethz.ssh2.Connection;
public class Ssh {
	public static boolean login(String host,int port,String user,String password){
		boolean l = false;
		try {
			Connection conn = new Connection(host, port);
			conn.connect();
			l = conn.authenticateWithPassword(user, password);
			conn.close();
		} catch (IOException e) {
			System.out.println(e.toString());
		}
		return l;
	}
}

Java连接Svn:

package org.javaweb.util;
import org.tmatesoft.svn.core.SVNException;
import org.tmatesoft.svn.core.SVNURL;
import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager;
import org.tmatesoft.svn.core.io.SVNRepository;
import org.tmatesoft.svn.core.io.SVNRepositoryFactory;
import org.tmatesoft.svn.core.wc.SVNWCUtil;
public class Svn {
    @SuppressWarnings("deprecation")
	public static boolean login(String url,String user,String pass){
        SVNRepository repository = null;
        try {
            repository = SVNRepositoryFactory.create(SVNURL.parseURIDecoded(url));
            ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(user,pass);
            repository.setAuthenticationManager(authManager);
            repository.testConnection();
            return true;
        } catch (SVNException e) {
            System.out.println(e.toString());
        }
        return false;
    }
}

Java连接SMTP（mail）：

package org.javaweb.util;
import java.util.Properties;
import javax.mail.Session;
import javax.mail.Transport;
public class Mail {
	public static boolean login(String host, int port, String user, String password) {
		try {
			Properties props = new Properties();
			props.setProperty("mail.smtp.auth", "true");
			props.setProperty("mail.transport.protocol", "smtp");
			Session session = Session.getInstance(props);
			Transport transport = session.getTransport();
			transport.connect(host, port, user,password);
			transport.close();
			return true;
		} catch (Exception e) {
			System.out.println(e.toString());
			return false;
		}
	}
}

Java连接FTP:

package org.javaweb.util;
import org.apache.commons.net.ftp.FTPClient;
public class Ftp {
	public static boolean login(String host, int port, String user,String password) {
		boolean f = false;
        try {
			FTPClient ftpClient = new FTPClient();
            ftpClient.setConnectTimeout(3000);
			ftpClient.connect(host);
			ftpClient.setDefaultPort(port);
            f = ftpClient.login(user,password);
            if(ftpClient!=null){
                ftpClient.logout();
                ftpClient.disconnect();
            }
		} catch (Exception e) {
            System.out.println(e.toString());
        }
		return f;
	}
}

Java连接数据库（Mysql只是示例，改下驱动的url和包驱动可以连接任何数据库）：

package org.javaweb.util;
import java.sql.DriverManager;
public class Database {
	public static boolean login(String driver,String url,String user,String password){
		try {
			Class.forName(driver);
            return DriverManager.getConnection(url, user, password)!=null;
		} catch (Exception e) {
            System.out.println(e.toString());
        }
		return false;
	}
}

Java连接LDAP:

package org.javaweb.util;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
public class Ldap {
    private static DirContext ctx;
    public static boolean login(String host,int port,String root,String user,String password) {
        Hashtable<String,Object> env = new Hashtable<String, Object>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://"+host+":"+port+"/" + root);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, "cn="+user );
        env.put(Context.SECURITY_CREDENTIALS, password);
        try {
            ctx = new InitialDirContext(env);
            ctx.close();
            return true;
        }catch (Exception e) {
            System.out.println(e.toString());
        }
        return false;
    }
}

测试代码：

package org.javaweb.util;
public class Test {
	public static void main(String[] args) {
        System.out.println(Ssh.login("ahack.net",22,"p2j.cn","111111"));
        System.out.println(Ftp.login("p2j.cn",21,"p2j.cn","111111"));
        System.out.println(Mail.login("smtp.163.com",25,"p2j@163.com","111111"));
		System.out.println(Database.login("com.mysql.jdbc.Driver", "jdbc:mysql://localhost/", "root", "111111"));
        System.out.println(Svn.login("svn://p2j.cn","svn","111111"));
    }
}

还有很多有意思的东西都可以试试，比如rdp、radmin、git等，Tomcat也可以爆破，之前发过了这里就不发了吧。
