            AWS - Private VPC Multiuser access to specific servers
            Asked 2021-Jun-08 at 05:19

            I need some suggestions for best practicality, security and maintainability

            The scenario is:

            • We have a private VPC with some servers,
            • We have users that can access server A and A only
            • Some users can access A, and B.
            • Other only B and so on.

            They need to access to theses servers from home and office.

            The current idea is having a multiuser OpenVPN server with IPTables blocking access to the servers that the user can't access

            Is there another option using AWS tools (VPCs,Security Groups, ACLs, Load Balancers, or others)?

            Or other solutions better than this one?

            Draw of current arch:

            • One boundary server that does the bridge from the open world to the Private VPC (With OpenVpn and IPTables)
            • 5 servers inside the private VPC
            • 10 Users with different levels of access

            Thanks

            Use AWS IAM to manage user access and permissions.

            For your scenario, you can create 3 groups: Server A, Server B, Server AB.

            Then attach IAM policy to each group. The policies will restrict access to specific EC2 only.

            How do I debug slow `ansible` (and `ansible-plabook`)?
            Asked 2021-Jun-05 at 10:54

            I'm facing a huge slow while managing a specific remote host with a specific role.

            I have tracked down the source of the slowness and found that for a very specific variable (defined for that specific host and used by that specific role), ansible and ansible-playbook takes up to 30 seconds to build it while for other variables it takes few seconds only.

            I have activated verbose mode and checked log file but nothing unusual except that ansible is completely silent (no logs are added) for a very long time for the problematic variable.

            My questions:

            • is there a way to debug ansible to get the root cause of the issue I'm facing?
            • anybody can suggest an explanation of this behavior?

            Here is the outcome of printing the problematic variable iptables and another normal variable ifcfg:

            With the help of @Zeitounator, I have solved the issue.

            The iptables variable is a dictionary with several levels and I have two more variables nets and ifcfg that are also dictionaries with several levels.

            Many values of iptables are set with values from ifcfg that are set using values from nets.

            I have managed to set values in iptables using values from nets directly and now the evaluation of iptables is as fast as the other variables.

            Raspi4 WIFI-Access-Point Full-Tunnel directly into Wireguard
            Asked 2021-May-31 at 14:56

            I run a working Wireguard server with 2 Wireguard Gateways for Site-to-Site VPN and a couple of Mobile Devices with a Full Tunnel that are used occasionally. One of my Site Gateways is a RaspberryPi4 that I want to provide a WIFI-Access-Point that directly tunnels to the Wireguard Server. This RaspberryPi has working access to all connected subnets via the main Server, so Wireguard is setup properly.

            I want to use my Raspi4 to roam the world and provide me a WIFI-Access-Point while any device that connects to it is directly routed into Wireguard and emerges to the web only from there. I used the standard gateway setup provided and my WIFI device can access the web but doesn't tunnel through Wireguard (yet).

            I can't really find where I can configure where the access point is bound to, dnsmasq, apdconf or a simply iptables rule?

            Example IPs

            Server: 10.0.7.1, local network 192.168.0.1/24

            Raspi4: 10.0.7.5, local network 192.168.6.5/24, WIFI 192.168.7.5/24

            First I changed the Wireguard-tunnel on the RP4 to be a full tunnel, it was previously a split-tunnel, only routing the IPs of the other local LANs into the wg0 interface.

            Kubernetes Helm Elasticstack CrashLoopBackOff with JavaErrors in Log
            Asked 2021-May-28 at 12:29

            I'm trying to deploy the ELK stack to my developing kubernetes cluster. It seems that I do everything as described in the tutorials, however, the pods keep failing with Java errors (see below). I will describe the whole process from installing the cluster until the error happens.

            ANSWER

            Answered 2021-May-26 at 05:06

            For the ELK stack to work you need all three PersistentVolumeClaim's to be bound as I recall. Instead of creating 1 30 GB of PV create 3 of the same size with the claims and then re-install. Other nodes have unmet dependincies.

            Also please do not handle the volumes by hand. There are guidelines to deploy dynamic volums. Use OpenEBS for example. That way you wont need to worry about the pvc's. After giving the pv's if anything happens write again with your cluster installation process.

            I was wrong obviously, in this particular problem, filesystems and cgroups take role and the main problem of this is an old problem. From 5.2.1 to 8.0.0. Reinstall the chart by pulling the chart. Edit values file and definitely change the container version. It should be fine or create another error log stack.

            Posting this as community wiki, please feel free and provide more details and findings about this topic.

            The only one place where we can find information about comma separated list of ports and port ranges is minikube documentation:

            Increasing the NodePort range

            By default, minikube only exposes ports 30000-32767. If this does not work for >you, you can adjust the range by using:

            minikube start --extra-config=apiserver.service-node-port-range=1-65535

            This flag also accepts a comma separated list of ports and port ranges.

            On the other hand from the k8s documentation:

            --service-node-port-range Default: 30000-32767

            I have tested this with k8s v 1.20 and comma separated list of ports also doesn't work for me. Kube-apiserver accept two approaches:

            set parses a string of the form "value", "min-max", or "min+offset", inclusive at both ends

            Standard network interfaces have a piece of hardware behind them (a network card).

            Tuntap don't:

            https://www.kernel.org/doc/Documentation/networking/tuntap.txt

            tl;dr: packets sent to a tuntap interface are handed over to a user-space program for processing. This program takes on the role of the network card in some way (example: openvpn). Unless there is a program taking packets out of the device and doing something meaningful with them, they will vanish into the void (like a network card with a disconnected cable).
