I was able to test this in my lab. Deployed with kolla ansible. Currently running Ussuri If I add the dns driver to the ml2 config, I am now able to resolve network ports DNS through the dnsmasq inside my private network. (venv) laurentdumont@openstack-deployer:/etc/kolla$ openstack port show 046068ee-4b1a-47b5-bfdb-91af916de1ee -c dns_assignment +----------------+------------------------------------------------------------------------------------------+ | Field | Value | +----------------+------------------------------------------------------------------------------------------+ | dns_assignment | fqdn='test-dns.os.coldnorthadmin.com.', hostname='test-dns', ip_address='10.100.100.112' | +----------------+------------------------------------------------------------------------------------------+ In this case, the VM has one port and the port takes the name of the VM. # nslookup -type=A test-dns.os.coldnorthadmin.com 10.100.100.2 Server: 10.100.100.2 Address: 10.100.100.2:53 Name: test-dns.os.coldnorthadmin.com Address: 10.100.100.112

The first link https://specs.openstack.org/openstack/charm-specs/specs/pike/implemented/internal-dns.html - is for an Openstack deployed with Charm. The second doc is correct. The file at /etc/neutron/plugins/ml2/ml2_conf.ini should be changed on the controllers. But the exact location will depend on how Openstack was deployed.

I don't think this is possible. The *.ini files are usually only configured by the cloud operators.

The container can be accessed via the ip which belongs to the docker_gwbridge interface. I was able to find out the ip address of the container on the docker_gwbridge interface by running the ifconfig command in the container itself: $ docker exec ifconfig This way the container can be accessed from host machine for example by 172.18.0.2:5432, without having to publish port 5432. Trying to find out the ip address via docker inspect (or or ) in swarm services did not lead to the desired result, because the ip from the docker_gwbridge interface was not displayed there. And the "internal" ip (something like 10.0.4.6) was not available from host machine.

As mentioned in https://stackoverflow.com/a/70804292/15962190 - name: "create block in own file per host" blockinfile: path: "/dir/logs/{{ inventory_hostname }}.txt" create: true block: "some commands" ... name: "add more line in block (even if already executed on another host)" lineinfile: line: "{{ item }}" ... loop: "{{ more_commands_1 | default([]) + more_commands_2 | default([]) }}" name: "assemble all files in one" assemble: src: "/dir/logs/" dest: "/dir/logs/all_hosts.txt" ... I used those modules along with check_mode: false and delegate_to: localhost. Those are handlers (in a role). I notify them in each module that execute commands on a device. Would be glad to use a more clever solution if it exists.

Usually, issues with port spawning will require admin access/logs to troubleshoot fully. It's harder with DVR, but you might have to trace each port creation and see where the delay happens. In Openstack, events are transiting through rabbitmq to provide the end to end orchestration. If one part of the process takes time, the overall process will be delayed.

Based on a tip from the https://www.reddit.com/r/ipfs/comments/rfe48b/comment/hoheoko/?utm_source=share&utm_medium=web2x&context=3 who says Hi, you have to edit ipfs config file you need to change the Address field to "/ip4/0.0.0.0/tcp/5001" I was able to solve the issue. To do so, I ran ipfs config Addresses.API /ip4/0.0.0.0/tcp/5001 and then systemctl restart ipfs Now I get the expected result

Anything that hasicorp created. Vagrant Terraform Ansible All tools for automating deployment of VM's and packages running on top of the VM's. API-based and all major providers implement the API's, also for on premise there implementations from VMWare, Virtualbox etc. Like you said there's many new terms to learn before you can work with it but it's a good path to follow

The IP addresses that are in your kubernetes cluster are internal to the cluster. There is nothing that would get an IP Address outside of your k8s cluster, like a dhcp from your router/dhcp server. K8s creates virtual adapters depending on the CNI runtime that you have implemented and it also creates domains for the objects inside. Anything inside k8s goes out through forwarding via the NodePort service type, so unless your network team specify which IP it is and which subnet they are tracking, I would suggest that you send them a large tcpdump to go through.

You have to bind server's port to something else when running it's container, using the --publish or -p flag. Take a look at examples and documentation https://docs.docker.com/config/containers/container-networking/ .

You have two solutions:Convert to your machine to link door of all machines in your network.Add static routes only to machines that need access to the VPN.Common tasks:Choose one option or another, your team will have to do the link door, so you must activate the package forward.In addition, since the teams at the other end of the VPN do not know the direction of your home network, you must mask the packages with the IP that your team has there, so that the packages know the way back.To achieve these two goals you must:Activate the reing of packages on the machine provided by the VPN: sysctl net.ipv4.ip_forward=1.Mask the traffic that is directed to the VPN with the IP of your computer so that the packages can return to their origin: iptables -t nat -A POSTROUTING -o tap0 -j MASQUERADE.Each distribution has a specific way to make these permanent changes. For example, by modifying the file /etc/sysctl.conf you can make the activation of the package relay permanent.However, the configuration of the firewall does change dramatically from one distribution to another, especially if you use an additional management layer as https://firewalld.org/ .If you want to turn your equipment into a link doorActivate masking to get on the Internet masking all the outgoing traffic (or specifying the interface that connects you to the router): iptables -t nat -A POSTROUTING -j MASQUERADE.Change the link door of your equipment to make it the PC that connects with the VPN.If you want to add static routes to the teams that need VPNAdd routes to each VPN subnet manually, for example route add -net 10.12.0.0 netmask 255.255.252.0 gw 192.168.1.200.Each distribution has a different way to make the routes persist after a reboot. There is also equivalent with ip route add, but it requires turning the net mask to https://es.wikipedia.org/wiki/Classless_Inter-Domain_Routing .

Your configuration syntatically and logically (des from the host point of view) makes sense.You lose the Internet connection because you LAN There's no one with ip 192.168.200.1 that can serve you to go out to the outside IP world.Your LAN configuration is logically not correct.The ping command can help you diagnose what's going on.ping al GW `ping 192.168.200.1ping to some ip public of inet known globally as 1.1.1.1 or 9.9.9.9 ping 1.1.1.1Yeah. 1 There's no loss, you certify that you're talking to him. GW No problem.

Generally servers that have public IP addresses have restricted access by a Firewall.They normally open ports related to https or https (80,443). The port you are trying to use (5555) is not usually open on the server or on the Firewall. To be able to establish communication successfully, therefore, you should only create a rule in the Firewall that allows such connection. The firewall can be the inside of the server operating system or can be a team intended for this task.Greetings.

What you can do is wait for the video download through Javascript and then play.It can be done in several ways:In http://dinbror.dk/blog/how-to-preload-entire-html5-video-before-play-solved/ link I recommend solution 3 and 4If you decide to use XMLHttpRequest, you can wait for the download to and then use document.getElementById("myVideo").play(). You may be interested in this https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest to understand how XMLHttpRequest works and https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/loadend_event where the event triggered at the end of the requestIn case you decide to use fetch https://github.com/AnthumChris/fetch-progress-indicators/blob/master/fetch-basic/supported-browser.js example is very goodI hope it serves you

The problem you suffer is that machines in the internal network use an IP address (192.168.100.0/24) to which the Internet router is not able to arrive by unknown through which equipment can access that network.The traffic generated by your internal network crosses the firewall, it sends it to the Internet router, but when the Internet router tries to send a package back it is lost by not knowing how to send it (or filters it or tries to make it back to the Internet, as its default route).There are two ways to solve the problem:Teach the router how to reach the internal network via a static route or dynamic protocols such as RIP or OSPF.Make the firewall make NAT to represent with its own IP the internal network teams before the router.Static routeThe easiest solution is to add a static route to the router by telling you that to 192.168.100.0/24 must send the packages to the firewall IP, 192.168.26.148.This procedure changes with each router model, so I cannot make a detailed explanation of the steps needed to complete this solution.Double NATIn order for the firewall to represent your IP to your internal network use the following instruction in the firewall:iptables -t nat -A POSTROUTING -o enp0s8 -j MASQUERADE From now on all packages that come out by the interface enp0s8 (the one that communicates the firewall with the router) will use the IP of that interface (NAT), so for practical purposes the router sees all the traffic of the internal network coming from the firewall, to which he knows how to send the packages back (and this one, following their NAT tables, will know to return the package to the initial origin).

Hello @Lucas Aldazabal, Your case is like the one I suffered.What happened to me is that the events that create the Socket were not eliminated, that makes them accumulate and generates me lost memory (memory leak). It happened that the messages took a lot and the program was saturating more and more.The solution I got was to remove the event that creates socket when you receive a message. I show you some code so you can understand it:const getMessage = (data) => { console.log('Message: ', data); socket.removeListener('message', getMessage) } socket.on('message', getMessage); //............. socket.emit('message', 'Un, dos, tres, pollito ingles...') I hope this will help you find a solution.Greetings

I think you have to allow input into the 2 interfaces and allow forward at bridge:iptables -A INPUT -i eth0 -j ACCEPT iptables -A INPUT -i virbr0 -j ACCEPT iptables -A FORWARD -i virbr0 -j ACCEPT

Maybe you mean nmtui.It is a graphical console interface for NetworkManager.

can be a "permission" error on iOS and add the following: <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> <key>NSExceptionDomains</key> <dict> <key>*</key> <dict> <key>NSExceptionAllowsInsecureHTTPLoads</key> <true/> </dict> </dict> </dict>

You can save the login and log closure for each PC where you consult the DB and ask if someone log in but has not been closed then do not allow the start of the application. Something like a flag.
