ipset

not talk about Nf-hipac, and similar to the above also ipset,ipset is encapsulated into a match and iptables linkage? Iptables is not bad, wrong in people simply should not directly expand each simple function into a set of Match/target consortium, the final form of disgusting code! Is that right?All right! I admit that the above yy are all right! But look at Nftables, can it play like this and play more?!

For the OpenStack security group, take the form of a question-and-answer record as follows1. Is it loaded on a compute node or a network node?is loaded in the compute node.2. Is it implemented using the iptable rule?The M version of neutron implements a Openvswitch-based firewall for streaming tablesPreviously common is implemented with iptables, typically creating neutron-openvswi-xxx chains3. Iptables implemented firewall method, the added rules are accept, the rest of the packages are drop?Ye

It is too troublesome to use different IP addresses to access the Internet in the lab and dormitory. I wrote two BAT files to modify them. @ Echo offecho set 422ip address set ADDR = 10.214.25.81set mask = 255.255.255.0set gway = 255.dns1 = 10.0.21echo 255.echo IP = % ADDR % echo mask = % mask % echo gateway = % gway % echo DNS = % dns1 % netsh interface IP Set address "Local Connection" static ADDR = % ADDR % mask = % mask % gateway = % gway % 1 netsh interface IP Set DNS "Local Connection" st

Each time I access the Internet from another location, I have to reset the IP address, which is quite time-consuming. So I wrote a batch of requests for automatic setting.Save the following code as the **. bat file in notepad, and change the IP address, gateway, DNS, and nic name to your own one. Run the command as an administrator.(1) set the dynamic IP address and obtain it automatically.@ ECHO OFFEcho ip address modification ToolECHO is setting to automatically obtain the IP address.

Reposted on: Qian Xiaozhi IP address Quick Switch The mobility of the current notebook is enhanced. We need to connect to the network in multiple environments and manually set the IP address, gateway, and other information each time without the vro automatically assigned, it is very cumbersome. In practice, the netsh command is used to quickly switch IP addresses. A. Basic usage 1. Create a New notepad and write the following information: Int IPSet

, such as the IP address, can be defined like a bash script. The lack of the rule operation plane of iptables is indeed a serious injury, but it cannot be killed by a stick. We know that ipset is one of the efforts to make up for this deficiency, the definition of the matching IP Set is handed over to the ipset program. We expect to see a lot of sets, such as protoset, portset, stateset... in this regard, w
