Zabbix Automatic Discovery (Discovery) Feature usage
With the monitoring host increasing, sometimes need to add a number of machines, especially the children's shoes just with Zabbix need to add all the company's servers to Zabbix, if using traditional methods to add devices, groups, projects, images ... the result should be the result of vomiting.
In view of this problem we can make good use of a Discovery (Discovery) module of the Zabbix great God

Apache Configure virtual host three ways, Apache virtual host
One, IP-based
1. Assume that the server has an IP address of 192.168.1.10, use Ifconfig to bind 3 IPs on the same network interface eth0:[Root@localhost root]# ifconfig eth0:1 192.168.1.11
[Root@localhost root]# ifconfig eth0:2 192.168.1.12
[Root@localhost root]# ifconfig eth0:3 192.168.1.13

In Linux, how does one modify the host name? in Linux, how does one modify the host name?
Step 1:Host name after modificationStep 2:Modify the hostname in/etc/sysconfig/networkStep 3:Modify the/etc/hosts file
Example:
The current host name of my machine is pc. to change it to target_pc:
1: Use the hostname command

Modify login host information in linux and host modification in linux
It usually manages more than 130 Linux physical hosts, so it is difficult to deploy applications to find out the IP information of each host!
Therefore, you must plan at the beginning of deployment:

ObjectiveWhen attempting to use SOCAT to establish server-side interface forwarding, it is found that the principle of virtual machine access network is not very understanding, and then the Internet to find information to understand how it is, and thus have this summary blog. Socat can establish a full-duplex communication channel between the server ports, which can be used for port data forwarding, which is said to be one of the three Linux/unix system artifacts.Virtual machine Virtual Network
A. Overview This article describes how to transfer files between a Linux host and a Windows host. Because sometimes, some files in a Linux host may be used in a Windows environment. For example, in the Linux host grabbed some pictures, want to upload them to the Windows host
The recent use of C # for network development requires processing of ISO8583 messages, since some of these fields are numeric, thus involving byte-order conversions when transmitting.Byte order refers to the order in memory of data that takes up more than one byte of memory, usually in two byte order, depending on where they are located we are called the host node Order and the network byte order respectively.Usually we think the network byte order is
