quality, progress control, project management and various models (iterative waterfall ...). Therefore, we need to redefine hash_function and hash_compare so that they can return a value! The idea behind it is that after the hash key and hash compare results are fixed, if the client IP address is changed at this time, there is still no error, it indicates that the hash search process has nothing to do with the source IP address and port of the receive

certificate as follows: Ll keys/ We can see that three files, ilanni. csr, ilanni. crt, and ilanni. key, have been generated. Here, we use the ilanni. crt and ilanni. key Files. In this way, the Client certificate is created. 4. Configure the Server After all the certificates are created, we now start to configure the Server. Server configuration file, which can be copied from the openvpn built-in template. As follows: Cp/usr/share/doc/

country in which KEY_COUNTRY is defined. The province in which KEY_PROVINCE is defined. The city in which KEY_CITY is defined. The organization in which the KEY_ORG definition is located. KEY_EMAIL defines the email address. The Unit in which KEY_OU is defined. KEY_NAME defines the name of the openvpn server. The above is all the content of The vars configuration file. We can also use the default configuration for the vars configuration file.

multiple verification methods and many powerful functions. OpenVPN operates on layer 2nd or layer 3rd of the OSI model and uses SSL/TLS protocol for network transmission. Supports various customer authentication methods, such as certificates, smart cards, and user name and password certificates. In addition, there is a powerful ACL function that limits the customer's information exchange. OpenVPN can run

I. openvpn introduction openvpn is an SSL-based vpn. it uses the industrial standard SSL/TLS protocol to implement the Layer 2 and Layer 3 secure data link VPN. it has the following advantages: 1. based on the SSL protocol, security, and using a single TCP or UDP port can achieve 2. using two-way authentication...

{node ID, the IP/port} ing table shows the VPN processing node to which the data is sent. 5. to use BIO instead of the network to implement TLS between nodes, you must understand that the SSL handshake has nothing to do with the network elements, just as the OpenVPN implements, you can use the BIO/Realiable layer to implement TLS negotiation between two memory buffers. In this way, a tunnel can be establis
