Network administrators need to know many things. First of all, you have to love, like and accumulate a little, but don't be impatient. You can't eat a steamed bun in one bite. You should be proficient in one or two knowledge and like everything, but the main thing must be learned, and the main thing must be mastered, that is, you must rely on your constant efforts and accumulation. If you can learn more knowledge, learn it first! Then learn more about what you like best, work for two or three years, then make a decision according to the situation, and then strive for an industry that can best develop your favorite!
The key to being a qualified network manager is to be a real person. Although it is said that "being a man is the most important.
Be the webmaster of Internet cafes:
1, doing network management, mainly maintaining the integrated wiring and network planning of servers, terminals, clients and networks. Maybe at first I felt a lot of workload, annoyed and stressed, giving others the feeling of impetuousness. After a period of work practice and life thinking, we can feel that the main problem is that they have not learned to adjust themselves and their interests in life, so the problems in natural work will be solved and they will understand life.
2. To be a qualified network administrator, it is most necessary to master reasonable network planning, dynamic management, static monitoring, remote debugging and maintenance, including network topology, transmission steps of network protocols, network traffic control, QOs, configuration and rational use of various protocols.
The network administrator is a technical post, so technology must be the first. As for what technology is the most important, it depends on the needs of each unit. Simply put, you just need to contact and exchange visits. Complex networks may be the business of several or even more people, so there will be division of labor and cooperation, and the direction of maintenance and research will be different. Generally, there is no network management in small and medium-sized units, because there are few computers, so there is no need to set up special posts. Ask someone outside if you have any questions. More than 20 units may need to set up special network management or part-time network management. The network management of such units needs all aspects of IT knowledge, and the wider the scope, the better.
Second, the skills that enterprise network management needs to master. To be a network administrator, you need to know almost everything, not necessarily be proficient. Of course, you should also have your own strengths.
1. The system is the most basic requirement. 1998 to 2003, you should be able to play linux from unix, but not all (this system is very difficult).
2. Be able to maintain computer hardware and printers (from needle printers to inkjet printers to laser printers). If you can't do this part well, you may be busy for half a day
3. The configuration and management of mail services and clients mainly include Exchange, IMAIL, Qmail, Sendmail, etc. Nowadays, enterprises have their own emails, and their status cannot be ignored.
4. For windows/*nix system, you should know the common service configurations, and the most basic ones are of course DHCP (DHCPD), DNS (BIND) and IIS (Apache).
FTP (Wuftpd/VSFTPD), AD (Samba), WINS, etc. If you don't understand these, make up quickly. Otherwise, don't go.
5. The database should at least understand SQL.
SERVER and MYSQL, if you can learn ORACLE/SYBASE/DB2/INFORMIX, the salary will definitely be high 10% (hehe, it's a bit exaggerated. If these are all cities, why not become a DBA? ).
6. Simple setup and management of switches and routers is necessary, otherwise you can only go to small enterprises (mainly Cisco, Huawei 3COM, Nortel, and of course you should be familiar with the low-end equipment of TP-Link and D-Link).
7. Be familiar with integrated wiring technology (at least 568A/568B) and know a little about optical fiber technology. If you are applying for a factory, optical fibers are often pulled between factories.
8. Know how to plan the network and improve the stability (most important), security and utilization of the network as much as possible.
9. You can write scripts. Whether you use windows or *nix, scripts will often make your work more efficient (languages such as assembly /C are better).
10. Know how to back up and restore data quickly and safely.
1 1. Be familiar with anti-virus technologies such as proxy firewall, or you won't know what happened when your network is completely down.
12.WLAN technology should be mastered as soon as possible, which is the trend, and some networks of many enterprises are integrated into it.
13. Familiar with access network technology, at least know what ADSL, ISDN, FTTX, FR and DDN are all about.
14. Of course, some companies require you to know ASP, PHOTOSHOP, DW, etc. When recruiting administrators. They are mainly for the daily maintenance of the website.
15. Have a clear understanding of the whole network model and architecture, at least know the layers, protocols, interfaces, services, etc. If you can read through the three volumes of TCP/IP protocol, then you can start working.
16. Have a clear understanding of ERP system.
17. The most important and decisive thing is to learn to endure. If you can't bear it, make a great plan. This sentence is very suitable for network management.
Ha ha. Having said that, do you think it is not easy to be a network administrator? Of course, don't think that network management is so easy to do. You only know how to install the system, get rid of the PC, and be an Internet cafe administrator at most (it's hard to say whether you are qualified or not, depending on whether you are familiar with the game, there may be a lot of problems when using diskless). A real network administrator must have profound knowledge, rich experience and keen insight.
