For switch0 and switch2, if it is a layer 3 switch, it needs to write a route, and if it is a layer 2 switch, it needs to write a gateway. Static NAT address Translation object network waiwanghost 192.168.1.2nat
The experimental results show that there are two authentication methods in PPP: pap and chap, which can be used alone or in combination. And one-way authentication can be carried out as well as two-way authentication. Pap authenticates by verifying that the remote user name and password match, while chap is
After we have added the hardware, we can view the specific Nic serial number in the configuration file / etc/udev/rules.d/70-persistent-net.rules. The rest of the Nic configuration steps remain unchanged. Please refer to the following: network mode: bridge mode, NAT
Configuring OSPF to introduce external routing networking of autonomous system requires that all switches run OSPF, and the whole autonomous system is divided into three areas. Where Switch An and Switch B act as ABR to forward routes between areas.
Experimental purpose: 1. DMZ publishes Web server, Client2 can access Server3, use command show conn detail to view Conn table, view routing table of ASA and AR [R1], configure ACL to prohibit Client3 from accessing Sev
Solution: remove the comments from # PasswordAuthentication no and change NO to YES / / kali. By default, yes modifies PermitRootLogin without-password to P
Background and questions when looking at the information compiled by others, I see the following code: package com.sitech.test;/** * automatic boxing and unpacking jdk1.6 * @ author liaowp * / public cl
Transistors are used in a small amount in our digital and analog circuits, and multiple transistors are also used on our pioneer board. In the part of the LED lamp on our board, there is the use of this transistor. Q16 in the LED circuit in figure 3-5 is a PNP.
Java deserialization-the principle that the transformedMap class can execute malicious code 0x00 code Map map=new HashMap (); map.put ("key", "value")
[TOC] introduction: static routing is the first entry protocol in the network foundation. We need to find out the context and understand the content of the routing network segment: 1. The working principle of router 2. The formation of routing table 3. Static and default routes (focus) 4. Encapsulation process of packets forwarded by routers 5
Personal understanding, time relationship, the writing is relatively messy, please forgive me. Topology: R2 is ASBR. On R1, we can see that the FA of LSA5 class sent by R2 is not zero. Key configuration for a unicast address: [R1] dis cur#sysname R1#router id
If there is no practice, there is no right to speak. Judging from my experience as a veteran IT driver for many years, the poor Wi-Fi experience is inseparable from the following three aspects. [remote association diagram] first of all, there are a large number of "remote associations" in wireless office networks. Generally speaking, when the user equipment chooses AP
The blackmail virus WannaCry (Eternal Blue) has swept the world and 90 countries have been hit. The domestic education network is the hardest hit. However, at a time when computers with relatively old versions of Windows are generally encountered, many computers install li
There are many adjustment algorithms in the operation, some of which are practical for homework adjustment, some are practical for process adjustment, and some are both practical. Several commonly used dispensing algorithms are introduced below. First come, first serve (FCFS) dispensing algorithm FCFS dispensing algorithm is the most complex
After the computer has just installed the system, we usually make a GHOST image backup and put it on another disk. We use winPE to make it, and take the virtual machine as the experimental object. We add a new disk E disk to the virtual machine in advance to put the prepared winP
NAT (network address translation) network address translation. The function of NAT technology: to convert illegal private network addresses into legitimate public network addresses. Advantages of NAT technology: saving public legal addresses, dealing with address overlap, enhancing flexibility, security

1. Provide MA5650 MA5626 firmware upgrade version 312 and configure 8 × × replacement service. As long as the hardware is supported, the working rate is guaranteed to be 1000Mbit/s and login password cracking recovery factory service. Oblique optical port old version of MA562X, can do 1-23 port isolation
Recently, I am working on SEP upgrade, so I would like to post a summary to share with you. The first step: the client patches the root certificate, distributes and deploys it with group policy or other methods (this patch is 436kb), and some problems that have been found in the test (2 were found when the test upgraded 10 hosts
NULL stands for unknown, uncertain value, so any value (including null value) and null value comparison is unknowable. In the on clause, where clause, Merge or case when clause, the result of any value and null comparison is fals.
