There was an order that I couldn t understand. Who can say. Thank you.

shutdown is a system shutdown command.

The computer shuts down after two hours.

shutdown –s –t 7200

If you want to shut down the computer at a specified time, the system needs to enable the scheduled task service, and the command is as follows:

For example, if you want to shut down at 22:00, you can stop at 22:00

time is the command to view the system time

c:\documents and settings\administrator>time

Then enter the time in the new time, date is the command to view the system date:

c:\documents and settings\administrator>date

Current Date: Friday, 2007-10-12.

Enter a new date: (YYYYYYYYYYYYYYYYYYYYYYYYY

If you want to automatically change the date when you turn on the phone, it is troublesome. Your battery can't record the time correctly, but you can still do it by executing the following command:

time: minutes: seconds: milliseconds.

date

Self saved as a batch file. In fact, it still feels very troublesome, because the current time still has to be obtained manually, and it is better to use Microsoft's time synchronization directly.

Finally, it is highly recommended to replace the battery, otherwise the BIOS will not be saved.

Countdown, by the second.

shutdown usage and parameters.

Usage: shutdown [-i |.] l | s | r | a] [f] [m \\computername] [t xx] [c "comment"] [d up:xx:yy]

l Log out (cannot be used with option -m).

r Shut down and restart this computer.

m computername remote computer shutdown reboot put-t xx sets the shutdown timeout to xx seconds.

c "comment"Close comments (127 characters maximum.)

f Force running applications to close without warning.

p is a planned closure**.

f: Forcibly close the application.

m Computer Name: Controls the remote computer.

i: Displays the graphical user interface, but must be the first option for shutdown.

l: Log out of the current user.

r: Shut down and restart.

c "The content of the message": Enter the message content in the shutdown dialog box (no more than 127 characters).

%1 is the representative parameter, this command is to load the system dll file in a loop, this is the batch command, generally run under the command line, that is, cmd

Execute on every dll file in %windir% system32:

s file.

Your computer is fine, these IP addresses are dynamically assigned, you use this address on the Internet this time, and use another address next time, and when you check the IP, the address in the database is the previous one, it is not in a hurry to update, and there is no need to update, because this kind of address changes too fast, there is no point in updating, only a fixed IP will be the correct address, of course, only the public security department has a special technology to find the real address, this technology is generally not civilian, some masters can also do it.

First of all, the answer upstairs is wrong.

These IPs are the IP addresses of all the routers that your machine has passed through to this IP, that is, how many hops have passed.

So your network is fine.

What can't you understand?

Some common options for netstat.

netstat –s

This option displays statistics for each protocol separately. If our application (e.g. a web browser) is slow or cannot display data such as web pages, then we can use this option to see what information is displayed. We need to look carefully at the rows of the statistics to find the keywords that are going wrong and determine what the problem is.

netstat –e

This option is used to display statistics about Ethernet. It lists items such as the total number of bytes of datagrams transmitted, the number of errors, the number of deletions, the number of datagrams, and the number of broadcasts. These statistics include both the number of datagrams sent and the number of datagrams received.

This option can be used to count some basic network traffic).

netstat –r

This option can display information about the route table, similar to the information you see later when using the route print command. In addition to displaying valid routes, it also displays the connections that are currently valid.

netstat –a

This option displays a list of all valid connections, including established connections, as well as those that are listening for connection requests.

netstat –n

Displays all valid connections that have been established.

It should be the hash code of the key.

Then perform bitwise and operation with the maximum integer, divide the result by numpartitions to get a remainder, and then return the int.

This means that the hash value is computed with the max value and then the remainder is followed by the passed parameters.

The number of partitions should be returned. It shouldn't be sorted.

& is a bit operator, compare is a bit! Then divide the thing in parentheses by numpartitions for the remainder.

It feels like it's used to allocate processors and the like.,According to the hashcode and the total number to allocate this, who should handle it.,But I don't know what the bit operation is for.,The result of bit-and-bit is itself.。

The first is to delete the default route.

The second is to add a static route from the default route - CIDR block.

That's what it means.

1. Delete the default route.

2. Add a default route, point to.
