In this example, we will configure DSA common key authentication for SSH2 on two machines (Machine A and Machine B. After the configuration is complete, we can log on to Machine B through SSH2 from Machine A without entering the password. we can also configure it as without passphrase (remember: This method is not recommended ). DSA public key authentication only applies to one host and one user, not to the entire system. this article assumes that you

need to install libnl. If an error occurs, install the following. Configure hostapd The hostapd configuration file is in/etc/hostapd. conf.Check my hostapd. conf.

environment and in public places. Another way is to keep the key unchanged, which makes the user vulnerable to attacks. Due to interoperability problems, academic environments and public places have never been able to use proprietary security mechanisms. The most powerful wireless encryption technology "WPA2" WPA2 is an IEEE 802.11i standard authentication form verified by the WiFi alliance.

Wireless routers offer three types of wireless security: WPA-PSK/WPA2-PSK, WPA/WPA2, and WEP. Security settings are different under different security types. 1. Wpa-psk/wpa2-psk WPA-PSK/WPA2-PSK security type is actually a simplified version of WPA/WPA2, which is based on

First, a Google Wiki for the interpretation of SSH key, the corresponding connection is: Https://wiki.archlinux.org/index.php/SSH_keys_ (%e7%ae%80%e4%bd%93%e4%b8%ad%e6 %96%87), here say a digression, Google is really better than hundred * degrees!!!SSH key pair allows you to easily log in to the SSH server without entering a password. Because you do not have to send your password to the network, the SSH key pair is considered to be a more secure way. Plus the use of

The completed window is as follows:which Reference Key comment: is a comment that does not affect the validity of the key, but can be used as a reference for distinguishing between other keys;Key passphrase and Confirm passphrase: used to protect the pri

minutes using today's notebook, and the original intention of WPA is to solve the WEP deficiency. To read the data being transmitted, Tews finds a dictionary-free attack method to crack the temporary Key Integrity Protocol (TKIP ). The cracking of WPA encryption will have a huge impact on users and vendors. WPA is currently one of the most common encryption standards, and there is also a more reliable standard WPA2 (it uses the Advanced Encryption St

places have been unable to use WEP. The disadvantage of WEP is that its encryption key is a static key and not a dynamic key. This means that in order to update the key, IT personnel must personally access each machine, which is not possible in an academic environment or public place. Another option is to keep the key unchanged, which makes the user vulnerable to attack. Due to interoperability issues, the academic environment and public places have been unable to use proprietary security mecha

Understanding mainstream wireless encryption methodsFirst, let's take a look at the mainstream wireless encryption methods, that is, the WEP, WPA, and WPA2 encryption methods that often appear in the security settings of wireless routers. WEP (Wired Equivalent Privacy, Equivalent Wired confidentiality ). According to the name, WEP seems to be a secure encryption protocol for wired networks, but this is not the case. The WEP standard was created in the

. The procedure is as follows: Enter 192.168.0.1 in the browser to configure the wireless router (take the D-Link Wireless Router as an example). In the last step, set the wireless network password in "set wireless communication online. The 802.11 standard defines a security protocol called Wired Equivalent Privacy WEP (Wired Equivalent Privacy). WEP can encrypt wireless data packets so that attackers cannot easily read these data packets. Two types of encryption are provided: 64-bit and 128-bit
