If I want to be a hotel network administrator

The hotel network administrator is mainly responsible for the maintenance, antivirus and software installation of all computers in the hotel, and cooperates with and assists the software suppliers used in the hotel. Close the network use of some office workers according to the instructions of superiors, be good at using office software, and make convenient functional reports according to the needs of hotel reports.

And the use of the internet (for guests) to assist the public security department in management (each city has different requirements). Because the guest's computer IP is different, adjust the IP to let the guest use the hotel network normally. . . "

1, the production of network cable is the basis of network management, and it is also one of the basic abilities necessary for a network administrator. There are two ways to make the network cable: a) Crosshair method: one end is connected with white orange, orange, white green, blue, white blue, green, white brown and brown; The other end is connected with white green, green, white orange, blue, white blue, orange, white brown and brown; B) Direct connection method: the two connections are: white orange, orange, white green, blue, white blue, green, white brown and brown. "In the production process, the center line must be straightened, and the copper wire and copper sheet should be completely contacted to avoid the failure of individual lamps and the waste of crystal heads during testing.

2. Set up * * * shared Ethernet. If the computers in the network are only connected through switches, the computers in the network must all belong to the same network segment in order to communicate with each other. If you want to access the WAN, you must go through a route.

3. Use the route print command to view the static routing table of this machine. Route add can add routes, and route delete can delete routes. When using tracert command to trace the route, if you encounter a firewall when accessing the external network, you will not be able to trace the route to obtain information; At this point, if you want to interrupt the path, you can use "CTRL+C" to terminate the trace.

There are many parameters behind the 4.Ping command, which can be used to test whether the network is normal. The default number of bytes for Ping to send a response request to the server is 32 bytes. For example, the server's IP is 10.22.70. 1, and each time it sends 1056 bytes, it needs to send 1000 response requests. We can use ping10.22.70.1–n1000–l1056. The parameter after -n indicates the number of times the response is sent, and the parameter after -l indicates the number of bytes sent each time. Similarly, the TTL parameter returned by the Ping command also contains a lot of information: we can judge what operating system is installed on the computer according to the TTL value. If TTL is less than or equal to 64, it means the current UNIX operating system, and 128 means the WINDOWS operating system. We can calculate the number of hops the network passes according to TTL value. Example: TTL=60 →60, so n=6, 2n =64, 64-60=4, that is to say, the hop count of network routing is 4.

5. You can use the net use \ \ IP address \ IPC $123456/user: tian command to create a new user and use.

Dir \\ IP address of the other party \ C$ You can view the directory of the other party's C drive. If you want to map the other party's C disk to the local K disk, you can use this command: net use K: \\ IP address of the other party \ C$. Therefore, the computer must set a complicated password, and must turn off * * * to enjoy resources, otherwise the computer is prone to Trojan virus.

6. VLAN setting of the switch. Because the same switch is set with VLAN, computers with different VLAN ports cannot ping each other. Only in the same VLAN port can they ping each other. Two switches are cascaded. If they are set in the same VLAN port, they can be pinged. Otherwise, they can only be pinged by setting routes.

As a network administrator, we should pay attention to the understanding and learning of network software and hardware in order to deal with and solve faults. The development of information technology is changing with each passing day and developing at a high speed. As a network administrator, we should practice more, accumulate experience in practice, constantly learn new knowledge, and strive to do better network management.
