Perl: storing results of pattern matching in an array

What's the output of the following script?

-------------------------------------------

#!/usr/bin/perl -w 

  $text = "abc_defg_hij_klm.";


  @a =($text =~ m/[a-z]+[_|\\.]/g);
  print "array A, size: ",  @a+0,  ", elements: ";
  print join (" ", @a);
  print "\\n";

  @b =($text =~ m/([a-z]+)[_|\\.]/g);
  print "array B, size: ",  @b+0,  ", elements: ";
  print join (" ", @b);
  print "\\n";


  @c =($text =~ m/([a-z]+)([_|\\.])/g);
  print "array C, size: ",  @c+0,  ", elements: ";
  print join (" ", @c);
  print "\\n";

------------------------------------------- 

The output is as follows:

--------------------------------
array A, size: 4, elements: abc_ defg_ hij_ klm.
array B, size: 4, elements: abc defg hij klm
array C, size: 8, elements: abc _ defg _ hij _ klm .

--------------------------------

What's difference of the three patterns?

The first one:  m/[a-z]+[_|\\.]/g -- no curves in this pattern, and the results matching the whole pattern are saved in the result array.

The second one: m/([a-z]+)[_|\\.]/g -- a pair of curves embrace the part of "[a-z]+", and the results matching this part are saved in the result array.

The third one: m/([a-z]+)([_|\\.])/g -- two pair of curves embrace the two parts of the pattern respectively, and the results matching the two parts are all saved in the result array in the order of ($1, $2, $1, $2, ...).

See. Do you learn the rule?

Run HCTS 5.0 on guests of OVM

HCTS 5.0 supports virtual machines. You can install two guests OS on a single OVM server, install HCTS 5.0 on the guests as TM and SUT respecitvely, and start the test between guests. This execution doesn't require any physical network connection between the two guests.

To perform it, follow these steps:

[1] Install OVM on a machine. This machine is OVM server.
    NOTE: Suppose the IP of the OVM server is 10.13.21.59,

[2] Install the first guest OS
    NOTE: Suppose the first guest OS to be installed is S10U9
[2.1] On OVM server

[2.1.1]  Download the guest OS installation ISO file on the OVM server.

       # mkdir /OVS/s10u9_iso
       and download the solarisdvd.iso file under /OVS/s10u9_iso

[2.1.2] # mkdir /OVS/running_pool/s10u9
      # cd /OVS/running_pool/s10u9
      # dd if=/dev/zero of=`pwd`/disk.img bs=1024K seek=20480 count=1

[2.1.3] # virt-install
      Would you like a fully virtualized guest? (yes or no) yes
      What is the name of your virtual machine? s10u9
      How much RAM should be allocated (in megabyts)? 2048
      What would you like to use as the disk (path)? /OVS/running_pool/s10u9/disk.img
      Would you like to enable graphics support? (yes or no) yes
      What would you like to use for the virtual CD image? /OVS/s10u9_iso/solarisdvd.iso

      Alternatively, the command could be as follows:
      # virt-install --hvm --vnc --name s10u9 --ram 2048 \\
        --file /OVS/running_pool/s10u9/disk.img \\
        --cdrom /OVS/s10u9_iso/solarisdvd.iso



[2.2] Turn to a remote machine (referenced as Working Desktop below)    

    # vncviewer 10.13.21.59:5900
    A GUI is openned, and you can continue with the S10U9 (guest OS) installation.


[2.3] On OVM server

[2.3.1]  # cd /
       # xm create -c s10u9

[2.3.2]\* (This step is for Solaris 10 only)
       # virsh attach-interface s10u9 bridge xenbr0

[2.4] On Working Desktop
    # vncviewer 10.13.21.59:5900
    Open vnc viewer window.

    # dladm show-link
    Check whehter the xnf0 interface has been added successfully.

    # ifconfig xnf0 plumb
    # ifconfig xnf0 dhcp or # ifconfig xnf0 <IP_address>/24 up
    (This <IP_address> ought to be in the same network segment as the OVM server's IP)


[3] Install the second guest OS
    NOTE: Suppose the second guest OS to be installed is OSOL_142

    Repeat [2.1] - [2.4] replacing 's10u9_iso' with 'osol_142_iso',
                         replacing 's10u9' with 'osol_142',
                         replacing 'solarisdvd.iso' with 'osol-dev-142-X86.iso'

    NOTE: (1) [2.3.2] could be ignored, since the xnf0 will be added to OpenSolaris automatically.
          (2) The port number in [2.2] and [2.4] would be changed to 5901, since 5900 has been occupied with the first one.


[4] Install HCTS 5.0 on the two guest OS

[5] Start HCTS 5.0 on guests, and set one as TM and another as SUT.

    The TM is set as Manual Network Configuration.
    The Manual Network Configuration option of SUT is enabled.
    A config file named as /opt/SUNWhcts/etc/sut_manual_ip.conf is generated manually. Its format is as follows:
    interface_name local_IP_address(SUT) remote_IP_address(TM)
    e.g.:
    xnf0 10.13.21.103 10.13.21.104

    Startup the system certification.

Display the tooltip of a JPanel node of a JTree

If you need a JTree composing of nodes each of that consists of icon, text and check box, which Java Swing component will you choose to adopt? JPanel will be the answer. 

Following is a example of such a JTree:

=====================

import java.awt.\*; 
import java.awt.event.\*; 
import java.util.EventObject; 
import javax.swing.\*; 
import javax.swing.tree.\*; 

public class PanelNodeTip { 
    private JScrollPane getContent() { 
        Icon icon = UIManager.getIcon("Tree.closedIcon"); 
        DefaultMutableTreeNode root = 
            new DefaultMutableTreeNode( 
                     new PanelNode("Root", false, icon, "Root Tip")); 
        root.add(new DefaultMutableTreeNode( 
                     new PanelNode("Node 1", false, icon, "Node 1 Tip"))); 
        root.add(new DefaultMutableTreeNode( 
                     new PanelNode("Node 2", true, icon, "Node 2 Tip")));

        JTree tree = new JTree(new DefaultTreeModel(root));

        tree.setEditable(true); 
        tree.setCellRenderer(new PanelNodeRenderer()); 
        tree.setCellEditor(new PanelNodeEditor()); 
        return new JScrollPane(tree); 
    } 

    public static void main(String[] args) { 
        JFrame f = new JFrame(); 
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        f.getContentPane().add(new PanelNodeTip().getContent()); 
        f.setSize(360,300); 
        f.setLocation(200,200); 
        f.setVisible(true); 
    } 


class PanelNode { 
    String name; 
    boolean value; 
    Icon icon; 
    String tip;

    public PanelNode(String s, boolean b, Icon icon, String t) { 
        name = s; 
        value = b; 
        icon = icon; 
    tip = t;
    } 

    public String toString() { 
        return "PanelNode[value: " + value + ", name:" + name + 
               "icon: closedIcon, " + tip + "]"; 
    } 

    public String getTip() {
    return tip;
    }


class PanelNodeRenderer implements TreeCellRenderer { 
    JCheckBox checkBox; 
    JLabel label; 
    JPanel panel; 

    public PanelNodeRenderer() { 
        checkBox = new JCheckBox(); 
        checkBox.setBackground(UIManager.getColor("Tree.background")); 
        checkBox.setBorder(null); 
        label = new JLabel(); 
        label.setFont(UIManager.getFont("Tree.font")); 
        panel = new JPanel(); 
        panel.setOpaque(false); 
        panel.add(checkBox); 
        panel.add(label); 
    } 

    public Component getTreeCellRendererComponent(JTree tree, 
                                                  Object value, 
                                                  boolean selected, 
                                                  boolean expanded, 
                                                  boolean leaf, 
                                                  int row, 
                                                  boolean hasFocus) { 
        DefaultMutableTreeNode node = (DefaultMutableTreeNode)value; 
        PanelNode panelNode = (PanelNode)node.getUserObject(); 
        checkBox.setSelected(panelNode.value); 
        label.setIcon(panelNode.icon); 
        label.setText(panelNode.name);

    label.setToolTipText("ToolTip Test for " + panelNode.getTip());
    tree.setToolTipText("ToolTip Test for " + panelNode.getTip());
        return panel; 
    } 


class PanelNodeEditor extends AbstractCellEditor 
                      implements TreeCellEditor, ActionListener { 
    JCheckBox checkBox; 
    JLabel label;     
    PanelNode panelNode; 
    JComponent editedComponent; 
    JPanel panel; 

    public PanelNodeEditor() { 
        checkBox = new JCheckBox(); 
        checkBox.addActionListener(this); 
        checkBox.setBackground(UIManager.getColor("Tree.background")); 
        checkBox.setBorder(null); 
        label = new JLabel(); 
        label.setFont(UIManager.getFont("Tree.font")); 
        panel = new JPanel(); 
        panel.setOpaque(false); 
        panel.add(checkBox); 
        panel.add(label); 
    } 

    public Component getTreeCellEditorComponent(JTree tree, 
                                                Object value, 
                                                boolean isSelected, 
                                                boolean expanded, 
                                                boolean leaf, 
                                                int row) { 
        DefaultMutableTreeNode node = (DefaultMutableTreeNode)value; 
        panelNode = (PanelNode)node.getUserObject(); 
        checkBox.setSelected(panelNode.value); 
        label.setIcon(panelNode.icon);         
        return panel; 
    } 

    public Object getCellEditorValue() { 
        if(editedComponent == label) 
            panelNode.name = label.getText(); 
        else 
            panelNode.value = checkBox.isSelected(); 
        return panelNode; 
    } 

    public boolean isCellEditable(EventObject anEvent) { 
        if (anEvent instanceof MouseEvent) { 
            return ((MouseEvent)anEvent).getClickCount() >= 1; 
        } 
        return true; 
    } 

    public void actionPerformed(ActionEvent e) { 
        editedComponent = (JComponent)e.getSource(); 
        super.stopCellEditing(); 
    } 
}   

=====================

Compile and execute the program of PanelNodeTip.java with JDK 1.5, you will found that there is no tooltip even if you put the mouse on any of the JTree nodes. What's wrong with it? I did add the lines of

label.setToolTipText("ToolTip Test for " + panelNode.getTip());
    tree.setToolTipText("ToolTip Test for " + panelNode.getTip());

If you execute the program with JDK/JRE 1.6, the tooltips display normally. However they doggedly disappear with JDK/JRE 1.5.

Is it a problem of JDK/JRE 1.5? Maybe. But I need the tooltips. What should I do?

The solution is simple. You just need to replace the line of

JTree tree = new JTree(new DefaultTreeModel(root));

with the following paragraph:

JTree tree = new JTree(new DefaultTreeModel(root)) {
        public String getToolTipText(MouseEvent ev) {
                if (ev == null) {
                      return null;
                }
                TreePath path = this.getPathForLocation(ev.getX(), ev.getY());
                if (path != null) {
                    DefaultMutableTreeNode node =
                        (DefaultMutableTreeNode) path.getLastPathComponent();
                    return ((PanelNode) node.getUserObject()).getTip();
                }
                return null;
           }
    };

    ToolTipManager.sharedInstance().registerComponent(tree);  

Now you can see the tooltips no matter with JVM 1.5 or 1.6.

Do you find what the text in the tooltip is displayed exactly? It is the panelNode.getTip() instead of "ToolTip Test for " + panelNode.getTip(). The lines of label.setToolTipText(...) and tree.setToolTipText(...) could be removed simply.

Request an Object Signing certificate from SunPKI Store with an Aladdin eToken Pro on Windows OS

Request an Object Signing certificate from SunPKI Store with an Aladdin eToken Pro on Windows OS


Hardware Security Module(HSM): Aladdin eToken Pro 72K
Software environment: Windows XP SP2 + eToken PKI Client 5.1 + JDK 1.6

Part 1: select Aladdin eToken Pro as the HSM device

An Object Signing certificate request can only be approved if the request was submitted using an HSM device. A HSM device is a specialized hardware cryptographic component that is used to generate and protect the private keys during any operations that involve that key.

For object signing, especially for signing objects in the form of JAR files (using jarsigner), the cryptographic hardware devices of choice are:
(i) Sun Crypto Accelerator 6000 PCIe Adapter (SCA 6000), and
(ii) SafeNet/Aladdin eToken (USB connected cryptographic device).

Considering the first one is too expensive (about $1300), we choose the Aladdin eToken Pro 72K (about $60).

Part 2: Prepare the Aladdin eToken Pro

2.1 Install Aladdin eToken PKI Client which could be downloaded from Aladdin web site or just require it from your Aladdin agent.

2.2 Plug the eToken into the USB slot of the system and select the "Initialization" function of the PKI Client to initialize the eToken.

2.3 Input a personal password (referred as <pin> as below) for the eToken.

Part 3: Request an Object Signing Certificate from SunPKI Store

3.1 Create (in current dir) file 'eToken-pkcs11.cfg' with the two lines

name = eToken
library = c:\\WINDOWS\\system32\\eTPKCS11.dll

3.2 Generate the key pair with following command

keytool -genkey -alias <alias> -validity 365 -keyalg RSA -keysize 2048 -sigalg SHA1withRSA -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin>


What is your first and last name?
Unknown: <your object name & version> (e.g. Sun Device Detection Tool)
What is the name of your organizational unit?
Unknown: <whatever> (e.g. Sun Microsystems Inc System)
What is the name of your organization?
Unknown: Sun Microsystems Inc (e.g. Sun Microsystems Inc)
What is the name of your City or Locality?
Unknown: <whatever> (e.g. Menlo Park)
What is the name of your State or Province?
Unknown: <whatever> (e.g. California)
What is the two-letter country code for this unit?
Unknown: US
Is CN=..., OU=..., O="Sun Microsystems Inc", L=..., ST=..., C=US correct?
no: yes

NOTE:

[1] Make sure JDK 1.6 is installed.
[2]
In Special Publication SP 800-57 Part 1 [SP800-57], NIST recommends using at least 2048-bit public keys for securing information beyond 2010 (and 3072-bit keys for securing information beyond 2030). So we use the '-keysize 2048' to generate the key pair.

[3]
The country code must be "US". Otherwise the next step would fail.

[4]
The generated key pair could be checked with following command:

keytool -list -v -alias <alias> -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin>


3.3 Generate the CSR with following command

keytool -certreq -alias <alias> -file ./certreq.csr -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin>

3.4 Submit CSR

Reference to https://wikis.sun.com/display/SunPKIstore/Corp+Object+Signing

3.5 Receive the certificate

You would receive an email from pkiadm@sun.com containing the certificate chain. The email will contain the certificates in two forms, ASCII/Base64 encoded and a binary PKCS7 attachment. You should import the ASCII/Base64 encoded form (not the PKCS7) because the import of the PKCS7 chain may not work due to bug 6731685 (fixed in JDK 7, but not earlier releases).

The ASCII/Base64 encoded form is a paragraph ascii characters embraced with
-----BEGIN CERTIFICATE-----
and
-----END CERTIFICATE-----

Copy the ASCII/Base64 encoded form certificate (those ascii characters including the two lines of -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----) and paste them into a single text file to save as 'cert.ascii'.

3.6 Import the certificate with following command

keytool -importcert -v -trustcacerts -file cert.ascii -alias <alias> -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin>

3.7 Verify the installed certificate chain with following command

keytool -list -v -alias <alias> -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin>

3.8 Signed jar files with following command

jarsigner -verbose -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg ./eToken-pkcs11.cfg -storepass <pin> <a jarfile name> <alias>

NOTE:

In step 2, 3, 6, 7 and 8, the eToken must be pluged in.

Rescue openSUSE grub

NOTE: The solution has tested on openSUSE 1.2 and openSUSE 11.1.

I installed openSUSE 11.1 and Windows 7 on a single hard disk. When the Windows 7 was out of gear, I rescued the Windows 7. The Windows OS works. However, the openSUSE grub was overwritten. I rescued the grub by following steps:

[1] Reboot the system with OpenSUSE 11.1 installation disc.

[2] Select 'Rescue System' and login with root.

[3] Enter grub interface by executing 'grub' in command line.

[4] INPUT: grub> find /boot/grub/stage1

    OUTPUT: (hd0, 4)

    INPUT: grub> root (hd0, 4)

           grub> setup (hd0)

    OUTPUT displays that it succeed.

[5] Reboot system. The grub is rescued.

Is the cacerts file in diablo-JRE 1.6 incorrect?

The size of cacerts file of diablo-JRE 1.6 (JRE on FreeBSD OS) is only 32Bytes. Compare with
the 63KB cacerts file of SUN Solaris JRE 1.6, the diablo cacerts is
almost an empty file. 

When I run an java application which transports date with HttpClient
with the diablo-JRE 1.6, the transportation fails. After I replaced the
diablo cacerts with a cacerts file from Sun Solaris JRE 1.6, the
application transports data successfully. 

Is it the diablo cacerts incorrect?

BTW: I sent emails to freebsd java alias to ask this question. But I receive no reply.

配置FreeBSD图形界面

freebsd 7.1及之前的版本,在安装了Xorg,并执行 Xorg -configure 后,会在/root 目录下自动创建xorg.conf.new   
运行#Xorg -config xorg.conf.new 测试新生成的xorg.conf.new配置文件。

如果看到一个黑灰的格子和一个X形的鼠标指针,那么配置就是成功的。如果要退出测试,只要同时键入Ctrl+Alt+Backspace。如果鼠标工作不正常,则需要先配置它。

将配置文件拷贝到公共目录中 #cp xorg.conf.new /etc/X11/xorg.conf

执行#startx,测试X11。如果看到一个黑灰的格子和一个X形的鼠标指针,那么Xorg就配置成功了,同时键入Ctrl+Alt+Backspace退出。


freebsd 7.2中的Xorg已升级,和以前不太一样,官方中文手册还没有更新,请参照英文手册
网址:http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html

以下为不同之处:

先要在 /etc/rc.conf 文件中加入:

hald_enable="YES"
dbus_enable="YES"

然后重新启动

进入root,运行 Xorg -configure 生成 xorg.conf.new 文件
运行 Xorg -config xorg.conf.new -retro 进行测试
注意加上 -retro,就会出现灰格子和X形鼠标,Ctrl+Alt+Backspace 退出

接下来是调整 xorg.conf.new 配置文件并作测试。用文本编辑器如 emacs(1) 或 ee(1) 打开这个文件。要做的第一件事是为当前系统的显示器设置刷新率。 这些值包括垂直和水平的同步频率。把它们加到 xorg.conf.new 的 "Monitor" 小节中:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync    30-107
        VertRefresh  48-120
EndSection

  在配置文件中也有可能没有 HorizSync 和 VertRefresh。 如果是这样的话, 就只能手动添加, 并在 HorizSync 和 VertRefresh 后面设置合适的数值了。 在上面的例子中, 给出了相应的显示器的参数。

  X 能够使用显示器所支持的 DPMS (能源之星) 功能。 xset(1) 程序可以控制超时时间, 并强制待机、挂起或关机。 如果希望启用显示器的 DPMS 功能,则需要把下面的设置添加到 monitor 节中:

        Option       "DPMS"

  关闭 xorg.conf.new 之前还应该选择默认的分辨率和色深。这是在 "Screen" 小节中定义的:

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth 24
        SubSection "Display"
                Viewport  0 0
                Depth     24
                Modes     "1024x768"
        EndSubSection
EndSection

  DefaultDepth 关键字描述了要运行的默认色深。 这可以通过 Xorg(1) 的 -depth 命令行开关来替代配置文件中的设置。 Modes 关键字描述了给定颜色深度下屏幕的分辨率。 需要说明的是,目标系统的图形硬件只支持由 VESA 定义的标准模式。 前面的例子中, 默认色深是使用 24位色。在采用这个色深时, 允许的分辨率是 1024x768。

  最后就是将配置文件存盘, 并使用前面介绍的测试模式测试一下。

    注意: 在发现并解决问题的过程中, 包含了与 X11 服务器相关的各个设备的信息的 X11 日志文件会为您发现和排除问题有所帮助。 Xorg 日志的文件名是 /var/log/Xorg.0.log 这样的格式。 实际的日志文件名可能是 Xorg.0.log 到 Xorg.8.log 等等。

  如果一切准备妥当, 就可以把配置文件放到公共的目录中了。 您可以在 Xorg(1) 里面找到具体位置。 这个位置通常是 /etc/X11/xorg.conf 或 /usr/local/etc/X11/xorg.conf。


完成相应配置,如刷新率、分辨率,测试完成之后,运行 #cp xorg.conf.new /etc/X11/xorg.conf即可


完成安装GNOME后,运行 #ee .xinitrc   (没有这个文件也这样做)
在这里输入 exec gnome-session
保存退出 (这里就是加gnome的 自动启动,也可直接用命令完成: #echo "exec gnome-session " > ~/.xinitrc )
然后 #startx就可以进入你的X-gonme了(如果你想开机就用图形方式进入X,你可以在/etc/rc.conf中添加 gdm_enable="YES")
好了,看到了X就先行了,下面配置安装其它软件呢什么的呢。ctrl+alt+backspace退回终端。
执行startx


另外,完成安装KDE4之后,运行#ee .xinitrc ,加入 exec /usr/local/kde4/bin/startkde
保存退出,运行startx即可进入KDE。注意startkde 所在目录和KDE3中不同

A new release of Sun Device Detection Tool -- support any platform and provide reports for OpenSolaris 2008.11

Sun Device Detection Tool 2.2 was released a few days ago. Besides the Solaris 10, OpenSolaris, Windows, Linux 2.6 and Mac X OS it supported before, Sun Device Detection Tool 2.2 can also run on FreeBSD 6 system. Now we can say that it runs on any platforms.

The new release provides driver db for the latest OpenSolaris and Solaris 10 OS . It could help you to decide whether OpenSolaris 2008.11 or Solaris 10 10/08 can run on your hardware.

The tool also enable you to submit your system configuration information to Sun for HCL auditing purpose (for Solaris 10 and OpenSolaris users only) or data mining.

Login OpenSolaris 2008.05 as \*root\* user

When you install the OpenSolaris 2008.05, there is page prompting you to input the root password along with creating a normal user. If you define a normal user at that time, you will find that you are not allowed to login the system with root user. 

What should you do? Re-install the system? It is a solution. But there is a much easier one as follows:

Revise the following line in the file of /etc/user_attr

----------------------

root::::type=role;auths=solaris.\*,solaris.grant;profiles=All;lock_after_retries=no;min_label=admin_low;clearance=admin_high 

----------------------

to

----------------------

root::::auths=solaris.\*,solaris.grant;profiles=All;lock_after_retries=no;min_label=admin_low;clearance=admin_high

----------------------

And then reboot the system. You can login as root again.

The tool is a Java application, and builds a JNI binding for each of the following interfaces to collect device information on mutiple platforms:

OS
Interface
Solution 
Solaris OS
libdevinfo
Looking up PCI nodes in prom tree and reading device data from the nodes
Windows OS
Win32 API
