Demand analysis A joint-stock financial service organization, whose core business is to operate the bank card information exchange Network, the supporting disaster backup system must be aimed at the system's potential interruption risk (disaster), provide the prevention mechanism, and ensure the continuous operation ability of the system. For a serious disaster that cannot be resisted, a system recovery me

The first contact with OpenStack, this piece is more headache, different documents, settings will vary, and can work, in the end which is correct? I'm afraid it's hard to come to a conclusion, here is a summary, the day sent to the mailing list for advice.The following settings, the final result, is that there is a network card into bridge, I understand bridge, is a switch, the virtual machine on the above

); By default, the traffic chart is displayed on the left side of the statistical data. The # chart is spelled out and displayed based on real-time traffic changes. Problem: when the network card traffic exceeds the transmission rate of the network card, the values on the right will not change to a fixed number. I thi

Do you know the 802.11n wireless network card? Do you know how to use a 802.11n wireless card to achieve higher performance? Don't worry, let's take a minute to explain. Quickly through the following understand it, will certainly let you have a different understanding of 802.11n wireless card. The descriptions in the

Differences between MAC address and IP address The MAC address is used to define the location of the network device. In the OSI model, the third layer of the network layer is responsible for the IP address, and the second layer of data link is responsible for MAC addresses. Therefore, the IP address of a computer can be changed dynamically, and the MAC address is fixed (without changing the NIC). What doe

When many users configure the sniff and command of the VPN virtual network card of the lingke router, they need to monitor the traffic of the virtual network card, but do not know how to set it, next I will introduce the VPN configuration of the lingke router. I. Through software, sniff can be performed on the virtual

Linux The kernel has been tested for a long time in terms of performance, especially 2.6/3.x kernel. However, in the case of high IO, especially the network, the processing of interrupts can become a problem. We have found this problem on a high-performance system with one or more saturated 1Gbps NICs, and recently there are many small packets concurrently (about 10000packets/second ) overload on the virtual machine also found this problem. The reaso

If the system has multiple network cards, you only want to configure a single network card. and make it effective without affecting the server's normal operation, as shown below1. Restart all network cards and load network card co

BrieflyAfter installing the CentOS operating system, found no network at boot, and finally found that the system does not activate the network card when booting-because only in the active state of the network card to connect to networks,

Under Windows, we can see 360 or QQ Security defender's "safety ball", which shows the real-time speed situation. So how to get the real-time speed of network card in Linux? In fact, the principle is very simple, read the network card needs to obtain the speed of a certain period of time in the DT traffic changes DL, t

Under the KVM can generate two types of network cards, RTL8139 and E1000, in fact, should be the underlying generation of different chips of the network card, and not with the host network card is what model is what model, wherein the default is 100 Gigabit

match-target rule, therefore, to implement bidirectional Nat, you must configure two rules.2. Compile a netfilter hook Writing a netfilter hook module is not difficult. I have written several articles by myself. However, the netfilter framework intercepts data packets in the protocol stack processing path for checking-matching/action, it checks each data packet that passes through the Protocol Stack. That is to say, each data packet must be filtered by the hook function. When there are too many
