Tested by: mx60 VoIP Voice Gateway Bug: getting the administrator password to log on to control the entire gateway. Impact scope: no device test is available for users with MX and operators, haha MX60 introduction Figure 1 Brief Description: MX60 is a carrier-level Voice Gateway. The permission settings for managing users are divided into two levels: Administrato

A route consists of two basic actions: determining the optimal path and transmitting information groups through the network. The Network Transmission Group is relatively simple, and the determination of the path can be complicated. BGP is a protocol for Path Selection in today's networks. This document briefly describes the basic operations of BGP and describes its Protocol components.
BGP implements Inter-Domain Routing in TCP/IP networks. BGP is an external
Satellite communication has played an important role in the global communication field since its emergence in 1960s. With the emergence of the Internet tornado, the satellite Internet technology combined with the Internet has become a new hotspot in the development of satellite communication.
Satellite Internet technology has developed rapidly recently and has become an important part of Internet connection. In order to adapt to the transmission of Internet services, satellite communication also
For example, two NICs are configured under CentOS, one for daily Internet access, and the other for connecting to the Development Board, which is configured in different network segments. Originally, NetworkManger is used under CentOS, DHCP is used to configure the network, but you want to learn about network management. Therefore, this function is disabled and IP Address Allocation and configuration are performed manually. But today something went wrong. After I turned on my computer, I found t
There is a machine in the LAN. Only some of the machines in the same network segment can be pinged or the gateway cannot be pinged. This is a strange phenomenon. I tried to modify the IP address and restart the network service, cannot solve the problem.
Check whether the gateway blocks the MAC address of the machine. Therefore, modify the MAC address of the machine as follows:
Ifconfig eth0 down
Ifconfig

Modify the configuration file for the corresponding NIC IPVi/etc/sysconfig/network-scripts/ifcfg-eth0Modify the following contentDevice=eth0 #描述网卡对应的设备别名, for example, in Ifcfg-eth0 file it is eth0Bootproto=static #设置网卡获得ip地址的方式, the possible options are static,dhcp or BOOTP, corresponding to statically specified IP addresses, IP addresses obtained through the DHCP protocol, IP addresses obtained through the BOOTP protocolbroadcast=192.168.0.255 #对应的子网广播地址HWADDR=00:07:E9:05:E8:B4 #对应的网卡物理地址ip
Want to test the cache server to run 2G of traffic to see. Try to let your IP scheduler to the server on the original basis, add 20% weights, so the request will be more on the original base of more than 20% of the amount. Originally the whole machine is basically floating in 800m-900m. So you have to use another network card to run, do not want to bind. This time, because of the new regulation, it has been monitoring its performance.
It's obvious that the back is getting bigger and
determine whether the filter is to be executed. We can use this method to specify the effective range of the filter.
Run: The specific logic of the filter. In this function, we can implement the custom filtering logic to determine whether to intercept the current request, not to follow the route, or to do some processing after the request route returns the result.
Zuul defines four different filter types by default, overwriting an external HTTP request to the API
in the daily work and life, some friends will buy back the router generally have to change the default gateway, this is also for security reasons. Today we are working together to discuss the method of changing the default gateway 192.168.1.1 to 192.168.0.1.

502 Bad Gateway Causes
A server (not necessarily a Web server) is a gateway or proxy to meet customer requirements, such as a Web browser or our Checkupdown robot, to access the requested URL. This server received an invalid response from an upstream server to fulfill its requirements.
Meaning
This usually does not mean that the upstream server has been shut down (no response
With the continuous development of the network, the manufacturing industry is also out of the traditional business model, the network has become the core of enterprise operation. The manufacturing industry can use the network platform, not only can realize the enterprise internal information exchange and the sharing, but also may use the network power, the application in the production, thus greatly enhances the production efficiency. However, in the continuous expansion of the network architect
Recently wrote some articles about the gateway, said to be written, rather than copy, before the firewall, encryption machine, network gate, VPN security gateway and other related equipment, can say just heard, nothing in-depth understanding. This time, in order to write a cryptographic machine operating norms, and the network gate operating norms, it is a charge of the strength of the breast. Finally, it's
So far, we have introduced a lot of the content of Spring cloud, Ribbon, Hystrix, feign the knowledge that everyone is familiar with, we also mentioned in the previous micro-service is to split a large project into a number of small independent modules, And then through service management let these independent modules work together. So let's think about this. Two questions: 1. If there are many independent services in my micro-service that have to be serviced externally, how will the developer o
Generally, all hosts in the same CIDR block have the same default route with the gateway as the next hop. When the gateway fails, all hosts that use the gateway as the default route in this segment cannot communicate with the external network.

Introduction
1. About the SIP protocol
Currently, there are three basic communication protocols based on VOIP: H 323, SIP, and MGCP. The following describes the comparison between the H 323 protocol and the SIP protocol.
H.323 was proposed by ITU. It attempts to regard IP phones as well-known traditional phones, but the transmission mode is changed from circuit switching to group switching, just like analog transmission to digital transmission, and coaxial cable transmission to optical fiber tra
