There are many things worth learning about the configuration mode of a Cisco router. Here we mainly introduce the mode of user execution and privilege of a Cisco router. Ping is the most commonly used troubleshooting command. It consists of a group of ICMP response request packets. If the network runs normally, a group of response packets will be returned. ICMP m
As more and more users choose wireless networks to improve their mobility, the safety of wireless networks is also starting to get a lot of attention. It can be said that wireless is more difficult to protect than a wired network, because the number of fixed physical access points in a wired network is limited, and any point that a signal can achieve in a wireless network can be used.
At present, the major brand manufacturers in the wireless router

You should have heard of DOS attacks more or less. The general principle is that the host initiating the attack sends a large amount of information to the attacked host to be processed, until the affected host cannot process other normal access requests, if more than one source address of the host initiating the attack is DDOS (distributed denial of service attack ), if the hardware configuration of the affected host is good enough, we can stick to it
