The more mature VTEP software implementations currently include: Linux with VXLAN kernel module Open VSwitch Let's start by looking at how Linux supports the Vxlan,open vSwitch approach, which is discussed later in this chapter.650) this.width=650; "Src=" http://7xo6kd.com1.z0.glb.clouddn.com/ Upload-ueditor-image-20161106-1478392973783000572.jpg "/>Implementation method: Linux Vxlan creates a UDP Socket, which is monitored by defau

In the previous section, we have configured and tested LBaaS, and today we focus on how Neutron uses Haproxy to achieve a balanced balance.Running IP netns on the control node, we found that Neutron created a new namespace qlbaas-xxx.The namespace corresponds to the pool "Web servers" we created. Its naming format is qlbaas-You can view its settings through IP a.The VIP 172.16.100.11 is already configured on the namespace interface. The corresponding

After completing step 4, a window appears. After about 8 minutes, the wep password will come out naturally. (In the cracking process, the ivs data packet is captured and can be decrypted between-in my experience.) 4. After ge

The VXLAN packet is routed based on the IP header of the outer layer, which takes the VTEP IP at both ends as the source and destination IP.In the next section we further understand the process of VXLAN encapsulation and forwarding packages through

interface qg-b8b32a88-03 of the router connection, a source NAT is made, and the packet's origin address is modified to router's interface address 10.10.10.2, so that the destination can send the reply packet back to router , and then forward back to the source-side instance.You can view SNAT's rules through the iptables command.When CIRROS-VM3 (172.16.101.3) pings 10.10.10.1, it is possible to verify router behavior by observing interface two SNAT ICMP packets by tcpdump respectively.vlan101 i

Preface Blockchain development is really fast this year. From the first unfamiliar concept, to now has started in various industries, a spark of great prairie fire. I wish I could have my own blockchain practice practiced hand O (∩_∩) o~. But a person, a computer, how to set up the blockchain environment ... It's not easy to say you love a block chain of fire. Don ' t worry! Small series have been addicted to blockchain and smart contracts can not extricate themselves. Now take your hands from

running on it, it is a storage node, and of course, other OpenStack services can be run on that node.Cinder-volume is a storage node hat, CINDER-API is a control node hat. In our environment, devstack-controller wear both hats at the same time, so it is both a control node and a storage node. Of course, we can also use a dedicated node to run Cinder-volume.This once again demonstrates the flexibility of OpenStack distributed architecture deployment: All services can be placed on a single physic

For OpenStack operations and administrators, in most cases, we don't need to look at the source code.Because OpenStack logs are detailed enough to help us analyze and locate the problem.But there are still some detail logs that are not documented and can be understood more clearly by looking at the source code if necessary.Even so, the log will provide us with clues to source code, and we don't need to find a needle in the haystack.This is what we'll see in the operational analysis that fo
