One, NIS definition
NIS (Network Information Service, Network information Services), also known as the YP (yellow Pages) protocol, is an RPC (remote procedure Call) application service that provides directory services. Through it, you can share a centralized password file on the network, which greatly simplifies the client user's maintenance of account and password.
Second, the experimental environment
Four CentOS5.4 servers, respectively, are:

training, so its sample set consists of a vector pair of shapes such as: (input vector, ideal output vector). All of these vectors should be the actual "running" result of the system that the network is about to emulate. They can be collected from the actual operating system. Before starting the training, all weights should be initialized with a few different small random numbers. The "small random number" is used to ensure that the network does not enter saturation due to excessive weights, re
the distance between P and Q must be less than D. So for each point in the gap, in the merge step, only the points within the yp+d and yp-d need to be inspected. Step 1: Sort the points in s based on the Y-values and X-values of the points. Step 2: Find out the midline l divides s into SL and SR Step 3: Apply Step 2 recursion to the application to solve the nearest point pair problem of SL and SR, and make
server to obtain the files. In general, commonly used files are:/etc/passwd,/etc/shadow,/etc/groups,/etc/hosts,/etc/services,/etc/networks,/etc/rpc,/etc/protocols ,/etc/aliases and so on. A cluster of NIS server and NIS client that we call an NIS domain. In each NIS domain, time synchronization must be performed, which is typically achieved by using the NTP service.In fact, with the development of technology, in the centralized authentication service, LDAP has gradually replaced NIS as a more a
After dinner, take a look at the code for digestion. Recently, many dede holes have been discussed in the Php0day group, so I quickly got down and used editplus to search for several keywords and found some problems. (Editplus is also used to write code, which is small and convenient for many years)The two files with vulnerabilities are:Include/payment/alipay. phpInclude/payment/yeepay. phpVulnerabilities occur in the respond method. It is estimated that the two files are written by temporary wo
NIS(Network Information Service)
NIS is a network product that centrally controls several systems for database management. NIS simplifies the management of UNIX and Linux desktop users. The client can use it to manage files on the central server. Users of the desktop system do not need to create their own/etc/passwd. They simply use files maintained on the NIS server.
When a client logs on to an account, it does not have its own home directory on the client. You can use an automatic mount device
The 10-bit or 12-bit CMOS analog to digital converter (ADC) comprises of 10-channel analog inputs. It convertsThe analog input signal into 10-bit or 12-bit binary digital codes at a maximum conversion rate of 1 MSPs5 MHz A/D converter clock. A/D converter operates with On-Chip sample-and-hold function. ADC supports lowPower mode.Touch screen interface can control input pads (XP, XM, YP, and ym) to obtain x/y-position on the external touchScreen device

Ym_sen: adctsc [7], ym switch enabling, select ym output drive effective (Gnd) Here, so it is 1.
Yp_sen: adctsc [6], YP switch enabling. In this case, the YP output driver is invalid (ain5), so it is 1.
Xm_sen: adctsc [5], enabled by the XM switch. In this case, the XM output driver is invalid (hi-z), so it is 0.
Xp_sen: adctsc [4], enabling the XP switch. Here, the XP output driver is invalid (ain7), so
must be less than D. Therefore, for each point in the gap, in the merge step, you only need to check the points in YP + D and YP-D.
Step 1: sort the values of Y and X in S.
Step 2: locate the midline L and divide s into SL and SR
Step 3: Apply Step 2 recursively to solve the closest point of SL and SR, and make d = min (DL, Dr ).
Step 4: Convert l-D ~ The points in L + D are sorted by y values. For each po
