I. Working principle: A. After the specified VLAN is enabled for DHCP snooping, the ports are divided into trusted interfaces and untrusted interfaces, the default VLAN all interfaces become untrusted interfaces, and the trusted interfaces need to be set manually. B. For the untrusted interface, you can only receive DHCP request messages and do not send DHCP request messages to this interface. C. For the untrusted interface, the DHCP response messages that are entered from the interface are a

TCP/IP test preparation: A simple timer-boost implementation, tcpboost The TCP/IP experiment needs to view the results at the specified time. For the convenience of the experiment, a timer is made. The usage is as follows: Enter timer in the command line.Enter a number and time the corresponding number of seconds.After the m number is input, the corresponding min

Because the friend said the port is not connected, deliberately tried the ping test with PHP, the result is quite satisfactory. The code and the run diagram are as follows: (if there is a great God to improve the better) $host = ' www.php100.com '; $port = ' 80 '; $num = 3; Ping times Get time function Mt_f () { List ($usec, $sec) = Explode ("", Microtime ()); Return ((float) $usec + (float) $sec); Microseconds plus seconds } function Pi

Linux redundant IP configuration, which has been tested on the AS4 system-Linux Enterprise Application-Linux server application information. The following is a detailed description. On the Solaris platform, dual-nic redundancy, we all know that you can use the IPNM (mutipath) mechanism to implement redundant IP addresses (floating IP addresses) for NICs. For Linu
