Of course, there are many times when you need to add routes. Operating system version centos-6.4 64bit One: Use the route command to add 1, the route command added by using the route, the machine restarts or the network card restarts after the route

About switch and router configurations it's impossible to use hardware when it comes to teaching. No condition today brings everyone is I do a small experiment. You can have the next Huawei ma5200g Simulator to experiment Specific orders and explanations I've written it all up. Hope and I like the dishes of friends and I do together! First, we've collected some basic commands for the switches.Usually commands:PCA login:root, using root userpassword:linux; password is Linux# shutdown-h now; sh

Set all IP addresses as shown2. Configure routing for different Machin

I. Use the route command in linux to addIf you use the route entry added by the route command, the route becomes invalid after the machine is restarted or the NIC is restarted.

CentOS 6.7 Add all methods for permanent static routes When using a dual-nic and two gateways at the same time, you need to add a static route. Of course there are still many times that you need to add routes. Operating system version centos-6.4 64bit I. Use the route command to add 1. Use the route command to add a route. After the machine restarts or the NIC restarts, the route will become invalid. Method: // Route entry to the host # Route add-host 192.168.1.11 dev eth0 # Route add-host 1

Tomcat log cutting and Regular deletion In the Tomcat software environment, if we allow unlimited growth of log files, the disk will be full one day (nonsense ). Especially when log files grow rapidly, it is necessary to cut and delete log files by log. The following describes how to cut log files.

=/sbin/init ipaddr = 10.0.14.143 netmask = 255.255.255.252 gw = 10.0.12.1 Of course, you can write a program for string analysis. This is the most conservative and stupid method... You need to write string Analysis on your own. It is better to solve the problem in the simplest way. Use sed in the script to implement the following: #!/bin/baship=`sed -n 's/ /\n/gp' /proc/cmdline | sed -n '/ipaddr/p' | sed -n 's/ipaddr=//gp'`netmask=`sed -n 's/ /\n/gp

creation: The malloc (sizeof (zval) that creates a variable and allocates space is not feasible in php. Should be used MAKE_STD_ZVAL (pzv ),It optimizes the space allocation and automatically initializes the refCount (indicating the number of times this variable is referenced) and is_ref (whether it is mandatory) attributes. Note that its input is a pointer. ALLOC_INIT_ZVAL ()You can also perform initialization. The difference is that zval * is set to NULL. There are many forms for setting dif
