How can I use the ping command to obtain the best MTU?What is MTU? MTU is called Maximum Transmission Unit in English. MTU refers to the maximum data packet size (in bytes) that can be passed over a layer of communication protocols ). The maximum transmission unit parameter is usually related to the communication interface (network interface card, serial port, etc ). When can I change the MTU value? For general router devices, the best MTU value is usually the default value. Sometimes, changing

Intranet interaction and the other for isp interaction. the actual topology is as follows: the isp line is directly connected to the vswitch, instead of the vro. The vro is also connected to a port of the vswitch. Its function is only for nat, re-encapsulate the original address of the package and the destination address of the returned package (see the original post). If the Intranet host wants to send pa

The original Article is from BlackSun. It is translated in sleep hours. This is a very good article and I am very happy to share it with you! Warning: Do not use this to damage the cisco system or access the system illegally. This article is for the purpose of learning. It can only be used for legal actions and cannot damage any system. This article will show you step by step how to use the discovered defects to obtain illegal access. If you break into a cisco router or disrupt the system, hundr

time we can configure the router protocol, so that the intranet can reach the router.8, configure the IP address of the ISP router, and test whether the ROUTE0 can ping the IP address of the ISP 202.1.1.2; Also test whether the intranet host can ping the IP address of the ISP router.9, Intranet is not able to ping the router IP address of the

completed and the upper device connection. General Wireless Router WAN port can support ADSL virtual dial-up (PPPoE), dynamic IP (dynamicipaddress, such as Fttx+lan access, Dsl+lan access, etc.), static IP (staticipaddress, such as the Green Line access) and other broadband access mode. And the powerful wireless router WAN port can also support the special L2TP, PPTP, 802.1x+ dynamic IP, 802.1x+ static IP and other Internet access mode. to set up the WAN port, you need to enter the IP a

I want these lines connected to the Internet to be load-balanced and to provide business-transfer functionality when a single line fails. I don't know how to set this configuration. What does my Internet service provider need to do? How do I set up my router? Answer: Your Internet service provider does not need to do anything. To achieve load balancing, the first step is to create an access list that divides your network into two parts. Based on this access list, you can define half of the IP

This guide describes how a small company with fewer than 255 workstations on an existing windows-based network can connect the computer to the Internet by using the Microsoft Internet Security Acceleration (ISA) Firewall secure service. 1. Configure Network Connections ISA firewall requires a computer equipped with two network adapters. One of the adapters needs to be connected to the internal network. Connect another adapter to your Internet service provider (

to connect to the mobile phone. Now you can use/dev/input/ttyacm0 as a common Modem for communication and prepare for a dial-up connection. For example, "Call home" shows how to use the popular dialing program wvdial for dialing. ----Call home To use the wvdial dialing program to dial data through a mobile phone, perform the following steps. Step 1: add the modem to/etc/wvdial. confFirst, add your modem to wvdial. conf. After addition, other tools such as Red Hat Network Manager can be used to

capacity, using BAP/BACP/MLPPP and other protocols to automatically allocate B channel to adapt to large data volume business, such as downloading files, pictures and even real-time voice and video, The B channel is automatically freed when the peak of data volume is past. The process of allocating and releasing B channels is transparent to the user. Because the SVC connection always exists, the user does not have to redial every time it is received, and the

solution to the problem in RFC6749, but attached some related RFCs to solve these problems, in addition to the 2 problem points mentioned in this article, there are other places that can be optimized (such as service discovery: https:// tools.ietf.org/html/draft-ietf-oauth-discovery-06), from Post Response mode:http://openid.net/specs/ oauth-v2-form-post-response-mode-1_0.html), these points in the follow-up oidc of the article again to introduce it, interested can take a look at http://openid.

Charter (Charter) The primary purpose of service governance is to gain the benefits of service-oriented architecture by nurturing reusable, enterprise-class services. As a functionally cross organization, service governance ensures timely resolution of problems and conflicts caused by the necessary compromises that are made when defining shared requirements. In particular, service governance organization

project plan is not a big plan, but it is a collection of plans detailing how different contexts and activities are managed under different conditions. He is a duly reviewed document and wants to be approved by the top management. The project plan is a Project Guide that can be refined as the project details are continuously understood. Although the project plan can evolve, some elements of the project do refuse to change. For example, the scope of the project, the scope of the project is to co

connection method, you can directly jump ); the first thing to confirm is what your "Broadband Access Method" is like? Of course, the simplest way is to give a call to your ISP Internet Service Provider. You can also make a quick judgment by using the previous network connection method of the router you purchased. ADSL/VDSL PPPoE: A computer runs a third-party dialing software such as Enternet300 or a dialing program provided by WinXP. Fill in the ac

Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the internal address to enable Internet access through multiple ISPs. Environment Description

What is Internet Traditional and non-traditional Internet terminals, all of which are called host or end systems. The end system is connected by a communication link and a packet switch. When data is transmitted from one end system to another, the sender system segments the data and adds the first byte to each segment. The resulting information package is called packet ). A group switch receives a packet from an inbound communication link and forwards the packet from an outbound communication li

! How to crack it !!! I suspect that I have set it on my account. I can only dial at 2.5! I tried to use two PCs to access the Internet as long as I use Star dial-up speed, so I suspect that China Telecom has not bound my NIC address. By the way, I used the cat and switch shared by Alcatel! Another idea I had was to manually use the star speed dialing + the cat routing function of Alcatel in a PC = shared Internet access. I tried it, that is, the cat dialing is required for simple debug
