Experiment Name: PPP PAP (CHAP) authenticationExperimental Purpose: Mastering the process and configuration of PPP PAP (CHAP) authenticationBackground description: You are the company's network administrator, the company in order to meet the growing business needs, the application of a dedicated line access, your customerThe client router authenticates with the ISP when it negotiates the link, configures th

: single two-way authentication: www.2cto.com 2.2, CHAP authentication: CHAP: Challenge Handshake Authentication Protocol, full name: challenge Handshake Authentication Protocol. CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified

Speaking of ppp, we will always involve CHAP. For the content of these two parts, we will discuss them in detail today. Here we will mainly explain the content about CHAP. Related Concepts and applications are also involved in PPP authentication configuration. For more information, see the following section. 1 PPP Overview Point-to-Point Protocol (PPP) is the data link layer Protocol for Point-to-Point line

Error message:You cannot use the question Handshake Authentication Protocol (CHAP) for identity authentication. There is no reversible encryption password for this user. To ensure that reversible encryption is enabled, you can check the domain password policy or password settings on your account. Solution: I had that policy set and it was not fixing my issue. The reason why it wasn' t fixing my issue, once you have this policy set you have Reset the

PPPThere are two authentication methods. One is PAP authentication. one disadvantage of PAP authentication is that the information is transmitted in plaintext when the user identity is verified, in this way, it is likely that a third party will steal the authentication information during the verification process, so the security is poor. One isCHAPAuthentication, the biggest advantage of this authentication is encrypted authentication during the authentication process, so most of the network use

word for each chunk of memory that vec_new () returns, and then to put the number of elements in that word. This is usually called a cookie. However, the Sun compiler maintains a " Union array, place the pointer and the size. It also maintains the destructor address in this array.The cookie policy has a generally worrying topic, which is that if a bad pointer is handed over to Delete_vec (), the cookie taken out is naturally illegal. An illegal number of elements and a bad starting address, Cau

still maintained because it does not know whether the Raccon pointer points to a true Raccon object or to a derived class object:Simple bitwise copy may suffice, may not be enough with Raccon *ptr; Raccon little_critter = *ptr;When an initialization operation exists and maintains the state of "bitwise copy Semantics", if the compiler can guarantee that object has the correct and equal initialization, should it suppress the call of copy constructor so that its resulting program code is optimized

Tasklet_schedule () function or tasklet_hi_schedule () function, Accordi NgTo the require of the tasklet. The functions is very similar, each of the them performs the followingActions1. Checks the tasklet_state_sched flag; If it is set, returns (the Tasklet have already been scheduled).2. Invokes Local_irq_save to save the state of the IF flag and to disable local interrupts.3. Adds the Tasklet descriptor at the beginning of the list pointed to by the tasklet_vec[n] or tasklet_hi_vec[n], where
