MAC and IP addresses tied to theft are no longer



In network management, IP address fraudulent usage is frequent, 涓嶄粎 normal use of the network impact, and because the address of the unauthorized use of authority is often high, thus causing a large number of users of economic loss and potential security hidden. What measures have the greatest possible to avoid such phenomena happen? In order to prevent IP address theft, you can assign the proxy server IP address, the IP address and network card address binding.

For dynamic allocation IP, do a DHCP server to bind the user network card MAC address and IP address, and then set according to different IP rights. For static IP, if using three switches, you can switch ports on each IP address so limited, if someone changes their IP address, then his network was unreasonable. We are now bound for the static IP address to explain an example.

View Network Card MAC Address

Click on "Start", select "Run" and then enter winipcfg command inside, which you can find out your network card address.

Record before the proxy server, allowing network administrators to a static IP address of your Internet records and the address of the computer's network card bundle. Specific command is:

ARP-s 192.168.0.4 00-EO-4C-6C-08-75

This will be your static IP address of the Internet (assuming that 192.168.0.4) and network card address (assuming a 00-EO-4C-6C-08-75) bound with a computer, even if your IP address stolen 192.168.0.4 can not access through a proxy server. One should note that this command only in the LAN Internet proxy server useful, but also a static IP address, like normal dial-up Modem is a dynamic IP address on does not work.

ARP function of each parameter Introduction

ARP 顨?s 顨?顨?d 顨?顨?a 顨?br />
-S - to the corresponding IP address and physical address of the bundle.

-D - delete the given IP address and physical address of the bundle.

-A - Arp protocol by querying the table to display the IP address and physical address corresponding to the situation.

As a network manager, if the MAC address and IP on the binding flexibility in the use of skilled, it will create a very safe environment conducive to security risks can be greatly reduced.

Taboo boss (below)



Although the right to a great boss, nor Lvyi act, but must first figure out what they should do, what to do taboo

Create antagonism

Some channels boss, believes a strange theory of management. They think: opposition factions within the company there, is conducive to his own mediator, this way, the opposition parties will rely on him to win the dominant position within the company, so he came to control the situation more conducive.

"No faction within the party, strange," he says, there factional differences within the company, this is also not surprising.

However, if the boss, "incited the masses to struggle," artificially create the internal opposition, it is unworthy. Such action, although the help owners improve the individual's authority, but the cost is: a lot of company resources will be wasted on "friction" on, just not worth it.

Another reason for opposition of faction, is thought by some employers employment. The blind boss to learn Western business practices cloning, the introduction of other people's "two-party system, cabinet system" to encourage the various factions within the company in turn form a cabinet, turns up the stage.

As everyone knows, "涓?湞澶╁瓙涓?湞鑷? and "new monarchs toward", in order to ensure the "New Deal" running smoothly, it is bound to be placed his trusted loyalists.

This time, the boss will be in a dilemma, if withholds the right personnel and how to show support for the new leadership, how to show their "Do Not Suspect?" However, when decentralization continues, often between rival factions would lead to personnel strife, and made both incompatible and ultimately fight was a lose-lose, and made the company debilitating.

Since the creation of internal opposition so harmful, how can this be prevented?

High-pressure policy, is clearly not a wise move, the "precious" and is the root of the problem.

How "and"?

The best way is to train up a new third-party power (or even more power), so that these new forces to act as mediator to resolve disputes.

However, these are just ways to remedy the fault, if we really want to solve this problem, they must follow the following principles: the various factions within the company can restrict each other, but never against each other.

Persecuted hero

The biggest taboo in boss damage, than persecuted hero.

Some bosses have a habit of people whenever men grow to a certain degree of time, we must strive to take the crowd out others.

Some employers, employers are courteous when, and once heroic name on, they began "burning bridges."

Why boss will "burning bridges"?

Reasons include the following: First, the main contributor to power high-shock and told the boss uneasy; second hero there own character weaknesses, so that the boss was intolerable; Third, some hero to be "packet out, day high and the emperor far away" so the boss was difficult to control.

Of course, there are more dark psychological boss. From the outset, they prepare secret: to a certain time, put the old people go to recruit a number of cheap new company, to save staff salary costs.

However, the persecuted hero of the consequences are serious.

First, the persecution of other cadres chilling meritorious will ask, have sought to protect themselves or even to prepare the brain drain;

Second, the persecution of heroic people would call a real deterrent, not coming to work; the villain is take the opportunity to stir up trouble and fish in troubled waters;

Third, the persecuted hero will increase the owner's suspicion, which is increasingly suspicious, and made the company feel insecure, and even deserted.

Therefore, the boss and hero, they should have the "broader picture" of psychology, we give way to each other step, road wider, we have the opportunity to develop.

Wronged good

The last taboo boss is a good man wronged.

As the saying goes: "a good man not good reporting." Why? Because good people often match for bad guys.

Why good match for bad guys?

This is because the good people of the brains used in the "General child" on; bad brains used in the "whole person" on. Ability to locate different professionals, have applauded the people how to fight bad guys off?!

Good not good report, of course, there are leaders fault not tell right from wrong; the other side, many of the "good guys" in the "personnel" was too rigid, too "Jieruchou" too idealistic, often leading to their passive reason.

So, let the good rewarded. On the one hand, they must constantly modify on the "good guys, bad guys" standard, personal likes and dislikes do not start to really selecting empowerment. Meanwhile, the "good guys" must have "good" self-cultivation, not demanding perfection of others, to be tolerant, to understand patience, know how to retreat, the leadership and colleagues to win the trust and respect. (Liang Bingru)

Prevent internal opposition, using high-handed policy, is clearly not a wise move, the "precious" and is the root of the problem.
