Unable to bind IPv6 address when NFS service startsIn the Test of NFS, suddenly there has never been a mistake, fault information as follows, for this purpose to describe the process of troubleshooting, for peer reference:Info:[[Email protected] ~]# Service NFS StartStarting NFS services: [OK]Starting NFS quotas: [OK]Starting NFS mountd:rpc.mountd:svc_tli_create:could not open connection for UDP6Rpc.mountd:svc_tli_create:could not open connection for
Now the network is very tight, and more users are joining the network, which leads to the lack of addresses. But there is already a solution, that is, the IPv6 protocol. However, most users still use IPv4, which leads to the IPv4 to IPv6 transition technology that we will discuss today.
IPv4 to IPv6 transition technology
Because of the size of the Internet and th
With the gradual evolution of the network, the surge in the number of users puts pressure on the network. The first problem to be solved is the shortage of Address resources. Now we have proposed the deployment of the IPv6 network environment, but the excessive problem is still the key to our solution. Now let's take a look at this issue.
To cope with this crisis, IPv6 technology is widely regarded as the m
This article is written to students in VPS, even if your VPS provider does not support IPV6, you can make your site IPv6 ready. If you have a lot of readers in the Education network, do this is very worthwhile, because the education Network has no international connection, but there are free IPv6. If your VPS service provider supports

1. 认识IPv6地址
IPv4地址是类似 A.B.C.D 的格式,它是32位,用\".\"分成四段,用10进制表示;而IPv6地址类似X:X:X:X:X:X:X:X的格式,它是128位的,用\":\"分成8段,用16进制表示;可见,IPv6地址空间相对于IPv4地址有了极大的扩充。
RFC2373 中详细定义了IPv6地址,按照定义,一个完整的IPv6地址的表示法:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

IPv6 has quietly come to our side. Windows 7 has started to support IPv6, but Windows 7 has not yet understood it, now, when I add an IPv6 package, the user will be confused. Next we will introduce how to configure IPv6 in Windows 7.
I. Initial problems:
Some schools update their internal network addresses to
IPv6 technology application in China is receiving more and more attention. Grasping IPv6 will drive China's information industry to take off. The powerful application prospect of IPv6 technology has brought tremendous changes to China's Internet Industry, benefits consumers to provide better and more affordable network services, and helps operators explore new bu
IPV6 and loopback address are short for Internet Protocol Version 6. Internet Protocol is translated into Internet Protocol ". IPv6 is the next-generation IP protocol designed by IETF (Internet Engineering Task Force) to replace the current version of IP protocol (IPv4. Currently, the version of the IP protocol is 4 (IPv4 for short), and its next version is IPv6.
ISP and Web companies have been setting up World IPv6 Launch Day for one year. Akamai reported that IPv6 traffic on the IPv6 content transmission platform has increased by 250%, the number of requests sent every day reaches 10 billion. Although this traffic is still far behind IPv4, it continues to grow. At the same time, the misunderstanding of
The current network IP resources cannot last long. Many experts predict that IPv4 addresses will be exhausted in the near future. To cope with this crisis, we generally think that the most effective solution is to apply IPv6 technology to the Internet. What new feelings can this IPv network environment give us?
Protocol conversion is required to enable multicast communication between an IPv4 host and an IPv6
In order to expand the network, we use the IPv6 protocol. As an improvement of the previous version protocol, the address type in the traditional sense is no longer applicable, now let's analyze the types of IPv6 addresses and basic knowledge about text representation.
The leading position in the address defines the specific IPv6 address type. A variable-length f
The research and construction of the next-generation Internet is gradually becoming one of the hot topics in the information technology field. The Network Security of the Next Generation Internet is an important area in the research of the Next Generation Internet. This article first introduces the basic features of the IPv6 protocol and the embedded security mechanism, and then analyzes and compares the similarities and differences of security issues
In the previous article, we have made a basic introduction to the IPv6 protocol stack design of wireless sensor networks. Then, based on the above content, let's take a closer look at the design of the Embedded IPv6 protocol stack. First, let's look at the idea of the Embedded IPv6 protocol stack.

IPv6: Why do I have to make up for IPv4 errors!
In the past ten years, IPv6 has been expected to develop a lot, but in fact this kind of good thing has not come, leading to a result, that is, most people do not know some knowledge about IPv6: What is it? How to use it? Why does it exist?
What does IPv4 do wrong?
We have been using IPv4 since the RFC791 standard
"IPv6 configured Commands"
IPv6 Install/Installation IPv6, limited to XP system use
IPv6 unicast-routing/Enable IPv6 forwarding, configuring on the router
Show IPv6 router/view IPv6
IPV6 is an innovation for IPv4, although most IPV6 routing protocols need to be redesigned or developed, IPV6 routing protocols have only a small change in relative IPv4. At present, various common unicast routing protocols (IGP, EGP) and multicast protocols have been supported by IPV6.

The transition from IPv4 to IPv6 is the trend of the times. However, due to the success and widespread use of IPv4, many researchers are actively exploring the technology of transition from IPv4 to IPv6. The existing technologies can be divided into three types: Dual-stack, translation, and tunnel. They can be divided into core network, enterprise network, and host at the network level.

Many of our friends downloaded the Linux operating system. With the network upgrading, we also need to configure IPv6 in our own system. Now, we will share with you the Linux IPv6 Configuration experience and hope that you can learn this configuration method.
Take RedHat9.0 as an example. The default kernel version of the system is 2.4.20-8, and the IPv6 module h
The driving force of technological development is the constant demand of people. With the increasing use of the Internet, the current network protocol version is no longer able to meet the needs of the times. Inevitably, we will launch a new generation of IPv6 network protocols that are more complete and have diverse functions. The inevitable elimination of IPv4 indicates that the development of the network will usher in its first innovation.
IPv6 standards are more conducive to carrying out a variety of services than IPv4 in terms of address space, security, and mobility. Therefore, IPv6 has the advantage of carrying out services from a certain perspective. From the perspective of business development, due to the limitations of IPv4, there is a certain problem in carrying out IPv4-based end-to-end services. Taking the development of P2P as an e
