Should I static if I'm not using nat on pix 6.2?
I have pix 6.2 and not nat address translation, I use everything I have nat from the East:
NAT (inside) - 0 200 access list
NAT (inside) 0 0.0.0.0 0.0.0.0 0 0
NAT (dmz:2) 0 0.0.0.0 0.0.0.0 0 0
and then I have the configured static next:
static (inside, outside) LotusSrv LotusSrv netmask 255.255.255.255 0 0
static (inside, outside) 81-mail mail-81 netmask 255.255.255.255 0 0
static (inside, outside) Bookstore Bookstore netmask 255.255.255.255 0 0
static (inside, dmz:2) 204.142.81.0 204.142.81.0 netmask 255.255.255.0 0 0
static (dmz:2, outside) Venus Venus netmask 255.255.255.255 0 0
and much more... but not for guests...
Lie, I have no overall control.
I just want to know what are these static commands, I can delete them and how to decide who hosts that I have to configure static?
Statix expose ip addresses of interfaces of high security to low security ints. Once created, you can then use pipes or access lists to allow access of ints low to high s ints. Then Yes, you need to keep all those who, if they provide services to the outside world.

Should we include the NIC do not use during P2V?
There are 2 NIC cards in a physical machine, but only one is used.
During P2V, should we include both of them and remove one not in use on a virtual machine? It is because we can choose the bad NIC card if we just choose a NIC card during the P2V process.
Your opinion is requested.
Hello
When you perform a P2V conversion, try to remove all the devices that you do not use from the server. This is also your chance to allocate hardware resources such as CPU or memory more or less, or adjust the allocated disk space.
When the conversion is completed, you will need to reconfigure the network settings, so it is not really important which NIC you remove server.
Best wishes / Saludos

Why not use the static methods - example
Hello world
I would like to continue the below thread about "why not use static methods.
Why not use the static methods
with the concrete example.
In my small application, I need to be able to send keystrokes. (java.awt.Robot class is used for this)
I created the following class for these "operations" with static methods:
You think it's a good solution? How could it be improved? I saw something Singleton vs somewhere of static methods. Wouldn't be better to use Singleton?public class KeyboardInput { private static Robot r; static { try { r = new Robot(); } catch (AWTException e) { throw new RuntimeException(e + "Robot couldn't be initialized."); } } public static void wait(int millis){ r.delay(millis); } public static void copy() { r.keyPress(KeyEvent.VK_CONTROL); r.keyPress(KeyEvent.VK_C); r.keyRelease(KeyEvent.VK_C); r.keyRelease(KeyEvent.VK_CONTROL); } public static void altTab() { r.keyPress(KeyEvent.VK_ALT); r.keyPress(KeyEvent.VK_TAB); r.keyRelease(KeyEvent.VK_TAB); r.keyRelease(KeyEvent.VK_ALT); } // more methods like paste(), tab(), shiftTab(), rightArrow() }
Thanks for your comments in advance.

Perhaps you could say also why do you say that it would be preferable to use singleton? What is behind it? Thank you!In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. If a singleton should be sufficient.
But who doesn't answer why he expected prefer a singleton instead of a bunch of static methods. Functionally, the two are almost identical. In both cases, there is that a single 'thing' to call methods - either a single instance of the class or the class itself.
To answer the question, the main reason to use a Singleton on a class of static methods is the same reason readers much of not static vs static decisions: polymorphism.
If you use a Singleton (and and interface), you can do something like this:
KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();
And then everything calling public methods of KBI has to know that there an implementor of this interface, without worrying about what concrete class is, and you can replace some implementation is appropriate in a given context. If you do not need to do, then the approach of the static method is probably enough.
There are other reasons that may suggest a Singleton - serialization, persistence, use as a JavaBean pop to mind - but they are less frequent and less convincing in my experience.
And finally, if this thing keeps updated a State between method calls, even if you can manage it with static member variables, it is more in line with the OO paradigm to make them non-static fields of an instance of this class.

should I turn the printer off when you are not using it?
you just buy new printer - HP envy 5530 - need to know if I need put it off when you are not using it or if it passes in mode "sleep"? other printers I had went to sleep mode however cannot locate this answer in the FAQ - like entry - thanks ~ ) husband
Welcome to the mgchandler forums,
I saw your post on want to know if you should be powered down the printer or if it won't fall in the mode 'sleep'. My best advice would be to turn off the printer by the power button if it will not be used for a period of time, for example during the night. Regards the mode "standby", the printer goes into standby after 5, 10 or 15 minutes of inactivity.
- To change the settings for sleep mode, go to the front screen of the printer and press settings (wrench)
- Contact preferences
- Press the arrow down and on Standby Mode when you see
- You can now change the time of mode 5 to 10 to 15 minutes before
User - Guide Page 93 + 94 for Info Sleep Mode
I hope I helped answer your question!
Have a great Tuesday

If I buy Creative Cloud subscription should I used products only in connection or without an internet connection, I will not use this app?
Hi alperb33255764,
You can use what you want, there is no such limitation. However when you go to cloud service based like loading or sync files to your cloud storage, you need an active Internet connection.
I recommend you see this KB doc for more information on creative cloud: https://helpx.adobe.com/creative-cloud/kb/creative-cloud-connection-faq.html
Kind regards
