Basic ideasidea One (origin:master): From a Wikipedia category (such as: Aircraft carrier (key)) page, to find the title of the link to include all the goals of the key (aircraft carrier), add to the queue to be crawled. In this way, grab a page of the code and its pictures, but also get this page all the key-related other pages address, take a class breadth first traversal algorithm to complete this task.I
hardware address of a device so that there is always a slave (curr_active_slave) using the hardware address of bond, while guaranteeing that each bond The slave in has a unique hardware address. If the curr_active_slave fails, its hardware address will be taken over by the newly elected Curr_active_slave.in fact, the difference between mod=6 and mod=0: Mod=6, the first eth0 flow accounted for, and then accounted for Eth1,....ethx, and Mod=0, will find 2 mouth flow is very stable, the basic same

Recently, new companies mainly work on static pages and write planning. The other is to learn about the communityserver project. It has been a month since we added up. On Saturday, I went to shangdiqi Street, a company. After talking with others, I found that this template class has been in use for a long time. When I came back, I thought I should add a feature that the template class always needed. Is to support information carriers. That is to say, in the custom tag parsing function, we can ob
I. Problem Description
The existence of Network Address Translation and firewall (NAT/FW) blocks multiple multimedia communication protocols, including H.323, because the NAT device only translates the IP address/port of the message header, the message's IP header is inconsistent with the address/port information in the message's Net Load. As a result, the Message Receiver cannot correctly respond to the message, and the media channels of both parties cannot be properly established.
In H.323 mul
Install BGP router in CentOS
How to simply use Quagga to turn the CentOS system into an uncompromising OSPF router is introduced. Quagga is an open source routing software suite. In this tutorial, I will focus onHow to change a Linux system into a BGP router or use Quagga to demonstrate how to establish BGP peer-to-peer with other BGP routers.
Before we enter the details, some background knowledge about BGP is necessary. The Border Gateway Protocol (BGP) is the actual standard of the Inter-Domai

Begin by checking if this is already installed by executing the following command:Rpm-q bridge-utilsIf the package is not yet installed, install it using yum:Su-Yum install bridge-utilsWith this package installed it is time to look at the current network configuration. the easiest way to do this is to run the ifconfig command. the following shows output from running ifconfig on a system on which KVM is installed, but on which a network bridge has yet to be configured:Eth0
