 # Node Status API
-
-The Node Status API contains information about the network, its topology, and the routing scores of all nodes within it. It offers broadly similar information to the experimental [Habourmaster frontend](https://harbourmaster.nymtech.net/) but is stable where the Harbourmaster is subject to sudden changes as we modify and experiment with how we scrape and present data about the Mixnet infrastructure.
+The Node Status API serves information about individual `nym-nodes` in the Mixnet, such as which role they are operating in, statistics about them, services such as Network Requesters, as well as summaries of the state of the Mixnet.
 
 <Callout type="info">
-People building applications or dashboards which requires information about nodes, their uptime, and their delegations should use this instead of Habourmaster.
+We recommend that developers building applications such as explorers or analytics interfaces about the Mixnet run their own instance of the API, in order to promote a robust network of downstream services, and spread the load of API calls amongst as many endpoints as possible.
 </Callout>
-
-The code for this service can be found [in our monorepo](https://github.com/nymtech/nym/tree/develop/nym-node-status-api). In the future we will encourage developers to run their own instance of this API in order to distribute endpoints and query load.

+# NS API: Deployment Guide
+
+## Components
+The Node Status API is made up of 3 components:
+- `nym-node-status-api`
+- `nym-node-status-client`
+- `nym-node-status-agent`
+
+The API stores its data in a local SQLite database. It periodically gets most of its data from a [NymAPI](./nym-api) instance, and for instances also running with the Gateway Probe, uses the stored topology to conduct performance probe tests.
+
+## Gateway Probe
+You can run the `nym-node-status-api` alone, but if you want to run probes for `nym-node`s running as Gateways, you have to also run the `nym-node-status-agent` (which consumes the `nym-node-status-client` lib). The probe will run a set of tests per Gateway node, and return the sort of results seen [here](https://harbourmaster.nymtech.net/gateway/23A7CSaBSA2L67PWuFTPXUnYrCdyVcB7ATYsjUsfdftb).
+
+## UI
+The API exposes a [Swagger](https://swagger.io/docs/) documentation UI by default on port `8000` (see an example [here](https://mainnet-node-status-api.nymtech.cc/swagger/)).
+
+Currently we are not shipping a custom UI component for the Node Status API. The [Harbourmaster](https://harbourmaster.nymtech.net/) frontend consumes this API, amongst other things, but this is an internal repo we use to experiment with new APIs and data on, so it is not public yet.
+
+<Callout type="info">
+We invite developers to roll their own UI for their Node Status API instance.
+</Callout>
+
+## Docker Images
+We will ship Docker images for both the `agent` and `api` in the future. There are Docker images for both in root of each corresponding crate ([`agent`](https://github.com/nymtech/nym/blob/09ea406c02e9a3beebc062f525e4ea1b4222dcbb/nym-node-status-api/nym-node-status-agent/Dockerfile), [`api`](https://github.com/nymtech/nym/blob/develop/nym-node-status-api/nym-node-status-api/Dockerfile)) which are used internally, which could be a starting point for developers to dockerize their instance for the moment.
+
+## Build
+### Prerequisites
+- Rust
+- SQLite
+- Get an `ipinfo` key following instructions [here](https://github.com/ipinfo/rust?tab=readme-ov-file#getting-started).
+
+### Compilation
+```shell
+cargo build --release --package nym-node-status-api --package nym-node-status-agent --package nym-node-status-client
+```
+
+## Run
+Since the Node Status API depends on both flags and environmental variables, it might be easier to run the binary via a script like the one below - this this script essentially just `source`-s the defined `.env` file after exporting certain binary-specific variables, and then runs the binary. You can find the `.env` files [here](https://github.com/nymtech/nym/tree/master/envs).
+
+<Callout type="info">
+    All CLI flags are configurable as environmental variables and vice versa, so take the following scripts / setups as guides that you can change however best suits your setup. You can see all definitions [here](https://github.com/nymtech/nym/blob/develop/nym-node-status-api/nym-node-status-api/src/cli/mod.rs#L14).
+</Callout>
+
+```bash
+#!/bin/bash
+
+set -e
+
+export ENVIRONMENT=${ENVIRONMENT:-"mainnet"} # see nym/envs/ for all possible environments
+export NYM_API_CLIENT_TIMEOUT=60
+export NODE_STATUS_API_TESTRUN_REFRESH_INTERVAL=120
+export IPINFO_API_TOKEN=<YOUR_IPINFO_API_KEY>
+
+monorepo_root=<PATH/TO/NYM/>
+set -a
+source "${monorepo_root}/envs/${ENVIRONMENT}.env"
+echo ${monorepo_root}/envs/${ENVIRONMENT}.env
+set +a
+export RUST_LOG=${RUST_LOG:-debug} # debug is useful to check everything is working initially, but quite verbose
+
+echo "Verifying environment variables were properly sourced:"
+echo "RUST_LOG=${RUST_LOG}"
+echo "BECH32_PREFIX=${BECH32_PREFIX}"
+echo "NETWORK_NAME=${NETWORK_NAME}"
+
+<PATH/TO/>nym-node-status-api -- --ipinfo-api-token $IPINFO_API_TOKEN
+```
+
+### Functionality Without Gateway Probe
+Data will be restricted to information that doesn't involve Probe results; `routing` and `config` scores will be `0` and `last_probe` results `null`, as you can see in this snipped output of the `gateways` endpoint:

+
+If you have already run the API before, make sure to add the following to your script `--database-url "sqlite://node-status-api.sqlite?mode=rwc` so it will continue using the same DB.
+
+### Functionality with Gateway Probe
+If you want to enable Gateway node probes and have the NS API store that data, you need to periodically run the `nym-node-status-agent`, authenticated with your `nym-node-status-api` instance. Authentication is to make sure that only the `-agent` you are operating (or others you trust) are submitting data to your API instance.
+
+#### Compile Gateway Probe
+The `nym-node-status-agent` is a thin wrapper around the Gateway Probe binary which currently is in the NymVPN repo. `git checkout` to the most recent [release](https://github.com/nymtech/nym-vpn-client/releases), and compile the probe by following the [readme instructions](https://github.com/nymtech/nym-vpn-client/tree/develop/nym-vpn-core/crates/nym-gateway-probe). You will point the `-agent` at this binary when doing Probe testruns.
+
+#### Generate Keypair
+```shell
+<PATH/TO/>nym-node-status-agent generate-keypair --path <PATH/TO/KEY/FILE/TO/GENERATE>/<KEY_NAME>
+# e.g.
+# nym-node-status-agent generate-keypair --path ~/.ssh/ns-agent-key
+```
+
+You will then want to export the generated `public-key` so its accessible to the `nym-node-status-api` however you are setting your environmental variables, as `NODE_STATUS_API_AGENT_KEY_LIST`:
+
+```bash
+export NODE_STATUS_API_AGENT_KEY_LIST=<YOUR_KEY> # e.g. "H4z8kx5Kkf5JNQHfxaE1MwRndjDCD1C7HsVhHTFfBZ4J"
+```
+
+In this situation, you are probably only using one key. However, it is possible to set multiple keys as a comma seperated list, in case you wish to whitelist multiple `-agent`s to be able to submit to a single `-api` instance.
+
+#### Run the Node Status Agent
+```shell
+<PATH/TO/>nym-node-status-agent run-probe --server-address http://127.0.0.1 --server-port 8000 --ns-api-auth-key "<NS_AGENT_PRIVATE_KEY>" --probe-path <PATH/TO/> nym-gateway-probe
+```
+
+You will see a lot of output like so:

+### Operators Updates & Tools
+
+- New advanced [guide to virtualise a dedicated server](nodes/preliminary-steps/vps-setup/advanced), providing steps for experienced operators and aspiring sys-admins who seek for higher optimisation and better efficiency of their work orchestrating multiple nodes.
+- New Service Grant program is being implemented by operators setting up new ~150 Exit Gateways following the updated [specs for `nym-node`](nodes#minimum-requirements)
+
+### Features
+- [Feature/chain status api](https://github.com/nymtech/nym/pull/5539):
+this PR introduces `/v1/network/chain-status` endpoint on nym api to give basic information about the current block as seen by this API (with some caching) and updates `/health` endpoint to give stall information.
+
+- [Add SURBs soft threshold](https://github.com/nymtech/nym/pull/5535): the IPR should try to keep a buffer of available SURBs to reduce latency.
+
+- [Simplify IPR v8](https://github.com/nymtech/nym/pull/5532): purge stuff from IPR v8 to simplify; use protocol field in v8.
+
+- [Shared instance for DNS AsyncResolver](https://github.com/nymtech/nym/pull/5523):
+make the `HickoryDnsResolver` use a shared instance by default to limit fd use. Now the multiple `nym_http_api_client::Client`s that get built should take advantage of a shared connection pool for DNS lookups. If for some reason a client does need an independent AsyncResolver this can still be done with the added `thread_resolver`  function.
+
+- [cherry-pick 17d3ff2d775f61aee381d90a304ed416c08f33fc onto dorina](https://github.com/nymtech/nym/pull/5519)
+
+- [cherry-pick 6e5d0dac1b75413c5f09122b0d953f8ec6ef48df onto dorina](https://github.com/nymtech/nym/pull/5518)
+
+- [feat: add config option for maximum number of client connections](https://github.com/nymtech/nym/pull/5513)
+
+- [IPR request types v8](https://github.com/nymtech/nym/pull/5498): Bump IPR request/response types to v8
+
+- [Support static routes for HTTP requests](https://github.com/nymtech/nym/pull/5487)
+
+- [added missing import to doctest](https://github.com/nymtech/nym/pull/5480)
+
+- [adjusted TestSetup::new_complex to ensure bonded node's existence](https://github.com/nymtech/nym/pull/5478)
+
+- [Trigger contracts CI on main workspace Cargo changes](https://github.com/nymtech/nym/pull/5477): since the contracts workspace depends on the common code in the main workspace, and since the contracts are critical to not have regressions in, trigger contracts CI on any changes to the workspace Cargo.toml and lock files.
+
+- [Run cargo autoinherit](https://github.com/nymtech/nym/pull/5460): run `cargo autoinherit` to move a bunch of dependencies to the workspace level. `Cargo.lock` remains untouched.
+
+- [Disable debug in wasm and wallet workflows too](https://github.com/nymtech/nym/pull/5459)
+
+- [Fix clippy::precedence](https://github.com/nymtech/nym/pull/5457): fix clippy warnings for the Rust beta toolchain.
+
+- [Provide Interval context with node descriptor endpoints](https://github.com/nymtech/nym/pull/5456): add current interval context information to existing enpoints using `build_skimmed_nodes_response` under the hood. This allows clients checking for a refresh to send the `epoch_uid` as a query parameter when fetching updates so the server can tell it that there have been no changes, instead of sending duplicate data over and over. The changes in this PR should be backwards compatible and never interfere with existing clients. The additions to the `NodeParams` are optional, so there is no error if a client does not send them. Old clients will not send `epoch_uid` by accident so they cannot accidentally clear their set of known nodes. In the response the status field is optional so if it is missing (e.g. if a new client talks to an old server) the connection still works. For old clients speaking to new servers, the json parsing will simply ignore extra information not included in the objects json spec.
+
+<AccordionTemplate name={<TestingSteps/>}>
+
+ Made a request to the `/api/v1/unstable/nym-nodes/semi-skimmed` endpoint:
+ - without entering an epoch_id
+ - with entering the current epoch_id
+ - with entering an old epoch_id
+ - with entering a future epoch_id
+ All results returned the same data, as expected

+- [Feature/add gbp currency](https://github.com/nymtech/nym/pull/5453)
+
+- [Add helper to extract a list of sqlite files with journal files wal/shm](https://github.com/nymtech/nym/pull/5452)
+
+- [Add a middleware layer to the nym api allowing for data compression](https://github.com/nymtech/nym/pull/5451): after Testing in a minimal example, this does work as expected. Routes still default to plain encoding, however if a client indicates support for a compressed encoding using the `Accept-Encoding` header then the served response will be compressed with the appropriate `Content-Encoding` header. ([Proof-of-Concept](https://gist.github.com/jmwample/c15a983e804fc338fee3d1b037d216b0))
+
+<AccordionTemplate name={<TestingSteps/>}>
+ Sent requests with and without Accept-Encoding: gzip to observe response behaviour
+ Verified if responses included content-encoding: gzip when compression was requested
+ Checked response file output to confirm actual compression occurred
+</AccordionTemplate>
+
+- [Condense core API functionalities and enable gzip decompression for reqwest payloads](https://github.com/nymtech/nym/pull/5450): this PR is intended to take out variables from our usage of HTTP requests in the `nym-http-api-client`. To do this the PR: (1) adds the `ApiClientCore` trait with the minimal feature required to send a request, (2) turns all request sending into trait extension automatically implemented for any type that implements `ApiClientCore`. This has the benefit of consistent expected behavior for all clients using `nym-http-api-client`, including features added going forward. FOR EXAMPLE this pr adds a default header `"accept-encoding: gzip;q=1.0, *;q=0.5"` which indicates that compression is preferred whenever available. Other features to keep in mind here are things like configurable retries, domain fallbacks, etc. Note: the `Apiclient` interface could be simplified, but that would require refactoring our downstream usages of the API. For now this isn't necessary as `ApiClient` is implemented automatically so it costs nothing to have it this way. It just allows divergent usage in downstream crates.
+
+<AccordionTemplate name={<TestingSteps/>}>
+ Measured nym-api response times before and after updating the API client using curl
+ Checked if the client automatically decompressed Gzip responses
+</AccordionTemplate>
+
+- [Seedable clients](https://github.com/nymtech/nym/pull/5440): Adds `DerivationMaterial` and accompanying methods to builders. `DerivationMaterial` encapsulates parameters for deterministic key derivation using HKDF (SHA-512). Use the `derive_secret()` method to generate a 32-byte secret. To prepare for a new derivation, call the `next()` method which increments the index. **It is the caller's responsibility to track and persist the derivation index if keys need to be rederived.**
+
+<AccordionTemplate name="Example">
+
+ ```rust
+ let master_key = [0u8; 32]; // your secret master key
+ let salt = "unique-salt-value".to_string();
+ let material = DerivationMaterial::new(master_key, 0, salt.as_bytes());
+
+ // Derive a secret
+ let secret = material.derive_secret().expect("Failed to derive secret");
+
+ // Prepare for the next derivation
+ let next_material = material.next();
+ ```
+
+</AccordionTemplate>
+
+- [Remove all recv_with_delay and add shutdown condition to loops in client-core](https://github.com/nymtech/nym/pull/5435): inside client-core we want to prepare the ground for moving a behaviour close to what we have in the vpn client. Remove all the recv_with_delay since we want to just stop. Add shutdown condition to all select loops to guard against the shutdown listener being polled inside the select blocks. Remove unwraps when sending on unbounded channels in case the receiver exits before the sender. Move `TaskClient` to be a member field so make it easier to wrap log errors in a shutdown check. Update all fork names to use underscore consistently, since the task separator is hyphen
+
+<AccordionTemplate name={<TestingSteps/>}>
+ Validated that all binaries including `nym-node`, `nym-client`, `nym-network-requester`, and `nym-socks5-client` are behaving well without indicating the presence of any unexpected errors or crashes
+</AccordionTemplate>
+
+- [Disable the test for checking the remaining bandwidth in nym-node-status-api](https://github.com/nymtech/nym/pull/5425): this check fails almost every time on CI, possibly due to rate limiting? It's not good to disable the check, but it's blocking CI as it stands now. Given that we have the check above for locating the ip, we at least have a little coverage.
+
+- [Dz nym node stats](https://github.com/nymtech/nym/pull/5418): removed obsolete fields from stats (blacklisted mixnodes, blacklisted gateways, bonded mixnodes, bonded gateways). Introduced nym-node scraping, beside just mixnodes. `/mixnodes/stats` now returns data for nym-nodes as well, which results in much more accurate "packets mixed" stats.

     - Thus we calculate two additional auxiliary `Load` values, for memory usage and swap usage, i.e.: `used_memory / total_memory` and `used_swap / total_swap` respectively.
     - Then we check whether either of the `MemoryLoad` or `SwapLoad` is bigger than the current base `Load` of the machine we have determined, if so, it's increased by one tier / bucket. For example, say the current machine load is `Load::Low`, but the memory usage is at 90% (`Load::VeryHigh`). that would result in the reported `Load` being bumped up to `Load::Medium` instead. The same logic applies with swap load, **however, only if the total swap > 1GB**. this is to prevent weird edge cases where the machine has hardly any swap.
     - Finally, the `.total` `Load` uses the same "tier bumping" behaviour using the `.total` and `.network` loads, i.e. `if network > machine`, then `total = machine + 1`. for example if `machine` `Load` is `Load::Low`, but `network` `Load` is `Load::Medium`, then the `total` `Load` is set to `Load::Medium` instead.

+# Advanced Server Administration
+
+This page is for experienced operators and aspiring sys-admins who seek for higher optimisation and better efficiency of their work managing Nym infrastructure. The steps shared on this page cannot be simply copy-pasted, they ask you for more attention and consideration all the way from choosing server and OS to specs per VM allocation.

+
+## Virtualising a Dedicated Server
+
+Some operators or squads of operators orchestrate multiple Nym nodes. Among other benefits (which are out of scope of this page), these operators can decide to acquire one larger dedicated (or bare-metal) server with enough specs (CPU, RAM, storage, bandwidth and port speed) to meet [minimum requirements](../../../nodes#minimum-requirements) for multiple nodes run in parallel.
+
+This guide explains how to prepare your server in order to be able to host multiple nodes running on separated VMs.
+
+<Callout type="info">
+This guide is based on Ubuntu 22.04, in case you prefer another OS, you may have to do a bit of your own research to troubleshoot networking configuration and other parameters.
+</Callout>
+
+### Installing KVM on a Server with Ubuntu 22.04
+
+**KVM** stands for **Kernel-based Virtual Machine**. It is a virtualization technology for Linux that allows a user to run multiple virtual machines (VMs) on a single physical machine. KVM turns the Linux kernel into a hypervisor, enabling it to manage multiple virtualised systems.
+
+Follow the steps below to install KVM on Ubuntu 22.04 LTS.
+
+#### Prerequisites
+
+<Callout type="warning">
+Operators aiming to run Nym node as mixnet [Exit Gateway](../../../community-counsel/exit-gateway) or with wireguard enabled should familiarize themselves with the challenges possibly coming along `nym-node` operation, described in our [community counsel](../../../community-counsel) and follow up with [legal suggestions](../../../community-counsel/legal). Particularly important is to [introduce yourself](../../../community-counsel/legal#introduce-nym-node-to-your-provider) and your intentions to run a Nym node to your provider.
+
+This step is essential part of legal self defense because it may prevent your provider immediately shutting down your entire service (with all the VMs on it) when receiving first abuse report.
+
+Additionally, before purchasing a large server, **contact the provider and ask if the offered CPU supports Virtualization Technology (VT)**, without this feature you will not be able to proceed.
+</Callout>
+
+Start with obtaining a server with Ubuntu 22.04 LTS:
+- Make sure that your server meets [minimum requirements](../vps-setup#nym-node---dedicated-server) multiplied by number of `nym-node` instance you aim to run on it.
+- Most people rent a server from a provider and it comes with a pre-installed OS (in this guide we use Ubuntu 22.04). In case your choice is a bare-metal machine, you probably know what you are doing, there are some useful guides to install a new OS, like [this one on ostechnix.com](https://ostechnix.com/install-ubuntu-server/).
+
+Make sure thay your system actually supports hardware virtualisation:
+- Check out the methods documented in [this guide by ostechnix.com](https://ostechnix.com/how-to-find-if-a-cpu-supports-virtualization-technology-vt/).
+
+Order enough IPv4 and IPv6 (static and public) addresses to have one of each for each planned VM plus one extra for the main machine.
+
+
+When you have your OS installed, validated CPU virtualisation support and obtained IP addresses, you can start configuring your VMs, following the steps below.
+
+> Note that the commands below require root permission. You can either go through the setup as `root` or use `sudo` prefix with the commands used in the guide. You can switch to `root` shell by entering one of these commands `sudo su` or `sudo -i`.
+<Steps>
+
+##### 1. Install KVM
+
+- Install KVM and required components:
+```sh
+apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst
+```
+<br/>
+<AccordionTemplate name="Component breakdown">
+- `qemu-kvm`: Provides the core **KVM virtualization** support using QEMU.
+- `libvirt-daemon-system`: Manages virtual machines via the **libvirt daemon**.
+- `libvirt-clients` Provides command-line tools like `virsh` to manage VMs.
+- `bridge-utils`: Enables **network bridging**, allowing VMs to communicate over the network.
+- `virtinst`: Includes `virt-install` for **creating virtual machines** via CLI.
+</AccordionTemplate>
+
+- Start the `libvertd` service:
+```sh
+systemctl enable libvirtd
+systemctl start libvirtd
+```
+- Validate by checking status of `libvirt` service:
+```sh
+systemctl status libvirtd
+```
+<br/>
+<AccordionTemplate name="Console output">
+The command output should look similar to this one:

+
+- In case you don't configure KVM as `root`, add your current user to the `kvm` and `libvirt` groups to enable VM creation and management using the `virsh` command-line tool or the `virt-manager` GUI:
+```bash
+usermod -aG kvm $USER
+usermod -aG libvirt $USER
+```
+
+##### 2. Setup Bridge Networking with KVM
+
+A **bridged network** lets VMs share the host’s network interface, allowing direct IPv4/IPv6 access like a physical machine.
+
+By default, KVM sets up a **private virtual bridge**, enabling VM-to-VM communication within the host. It provides its own subnet, DHCP, and NAT for external access.
+
+Check the IP of KVM’s default virtual interfaces with:
+
+```bash
+ip a
+```
+<br/>
+<AccordionTemplate name="Console output">
+The command output should look similar to this one:
+```

+
+
+By default, KVM uses the `virbr0` network with `<IPv4_ADDRESS>.1/24`, assigning guest VMs IPs in the `<IPv4_ADDRESS>.0/24` range. The host OS is reachable at `<IPv4_ADDRESS>.1`, allowing SSH and file transfers (`scp`) between the host and guests.
+
+This setup works if you only access VMs from the host. However, remote systems on a different subnet (e.g., `<IPv4_ADDRESS_ALT>.0/24`) **cannot** reach the VMs.
+
+To enable external access, we need a *public bridge* that connects VMs to the host’s main network, using its DHCP. This ensures VMs get IPs in the same range as the host.
+
+Before configuring a public bridge, **disable Netfilter** on bridges for better performance and security, as it is enabled by default.
+
+- Create a file located at `/etc/sysctl.d/bridge.conf`:
+```bash
+nano /etc/sysctl.d/bridge.conf
+
+# in case of using custom editor, replace nano in the syntax
+```
+
+- Paste inside the following block, save and exit:
+```ini
+net.bridge.bridge-nf-call-ip6tables=0
+net.bridge.bridge-nf-call-iptables=0
+net.bridge.bridge-nf-call-arptables=0
+```
+
+- Create a file `/etc/udev/rules.d/99-bridge.rules`:
+```bash
+nano /etc/udev/rules.d/99-bridge.rules
+```
+
+- Paste this line, save and exit:
+```bash
+ACTION=="add", SUBSYSTEM=="module", KERNEL=="br_netfilter", RUN+="/sbin/sysctl -p /etc/sysctl.d/bridge.conf"
+```
+
+This disables Netfilter on bridges at startup. Save, exit, and reboot to apply changes.
+
+- Disable KVM’s default networking. Find the default network interface with:
+```bash
+ip link
+```

+The bridged interface `br0` now has the IP `<HOST>`, and `<INTERFACE>` shows `master br0`, indicating it is part of the bridge.
+</AccordionTemplate>
+
+Alternatively you can use `brctl` command to display the KVM bridge network status:
+```bash
+brctl show br0
+```
+
+##### 4. Add Bridge Network to KVM
+
+- Configure KVM to use the bridge by creating `host-bridge.xml`, open a text editor and pate the block below:
+```bash
+nano host-bridge.xml
+```
+
+```xml
+<network>
+  <name>host-bridge</name>
+  <forward mode="bridge"/>
+  <bridge name="br0"/>
+</network>
+```
+
+- Start the new bridge and set it as the default for VMs:
+```bash
+virsh net-define host-bridge.xml
+virsh net-start host-bridge
+virsh net-autostart host-bridge
+```
+
+- Verify that the KVM bridge is active:
+```bash
+virsh net-list --all
+```
+<AccordionTemplate name="Console output">
+```bash
+root@nym-exit:~# virsh net-list --all
+ Name          State    Autostart   Persistent
+------------------------------------------------
+ host-bridge   active   yes         yes
+```
+</AccordionTemplate>
+
+KVM bridge networking is successfully set up and active!
+
+Your KVM installation is now ready to deploy and manage VMs.
+
+</Steps>
+
+### Setting Up Virtual Machines
+
+After finishing the [installation of KVM](#installing-kvm-on-a-server-with-ubuntu-2204), we can move to the virtualisation configuration.
+
+> **The steps below will guide you through a setup of one VM, therefore you will have to repeat this process for each VM**. That also means that you have to be mindful of space and memory allocation.
+
+<Steps>
+##### 1. Install OS for VMs
+
+This is the OS on which the nodes themselves will run. You can chose any GNU/Linux of your preference.  For this guide we are going to be using Ubuntu 24.04 LTS (Noble Numbat) cloud image from [cloud-images.ubuntu.com](https://cloud-images.ubuntu.com/noble/current/).
+
+- Download Ubuntu Cloud image:
+```bash
+wget https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.img
+```
+- Copy the image to to `/var/lib/libvirt/images/` asigning to it a name your VM
+```bash
+cp noble-server-cloudimg-amd64.img /var/lib/libvirt/images/<VM_NAME>.img
+
+# for example:
+# cp noble-server-cloudimg-amd64.img /var/lib/libvirt/images/ubuntu-1.img
+```
+
+##### 2. Create and resize a virtual machine
+
+- Get `guestfs-tools` to be able to customize your login credentials:
+```bash
+apt install guestfs-tools
+```
+
+- Define login credentials:
+```bash
+virt-customize -a /var/lib/libvirt/images/<VM_NAME>.img --root-password password:<PASSWORD>
+# for example
+# virt-customize -a /var/lib/libvirt/images/ubuntu-1.img --root-password password:makesuretosaveyourpasswordslocallytoapasswordmanager
+```
+
+- Use `qemu-img` tool with a command `resize` to create a VM according your needs. You can see `qemu` [documentation page`](https://www.qemu.org/docs/master/tools/qemu-img.html) for more info on how to use it correctly.
+```bash
+qemu-img resize /var/lib/libvirt/images/<VM_NAME>.img +<SIZE_IN_GB>G
+# for example
+# qemu-img resize /var/lib/libvirt/images/ubuntu-1.img +100G
+```
+
+- Resize it from within it after `virt-install` command:
+```bash
+virt-install \
+--name <VM_NAME> \
+--ram=<SIZE_IN_MB> \
+--vcpus=<NUMBER_OF_VIRTUAL_CPUS> \
+--cpu host \
+--hvm \
+--disk bus=virtio,path=/var/lib/libvirt/images/<VM_NAME>.img \
+--network bridge=br0 \
+--graphics none \
+--console pty,target_type=serial \
+--osinfo <YOUR_CHOSEN_OS_NAME> \
+--import
+```
+
+- In our example we go with 4 GB RAM on the same machine as before:
+<br/>
+<AccordionTemplate name="Command example">
+```bash
+virt-install \
+--name ubuntu-1 \
+--ram=4096 \
+--vcpus=4 \
+--cpu host \
+--hvm \
+--disk bus=virtio,path=/var/lib/libvirt/images/ubuntu-1.img \
+--network bridge=br0 \
+--graphics none \
+--console pty,target_type=serial \
+--osinfo ubuntunoble \
+--import
+```
+</AccordionTemplate>
+
+- After loading you should see a login console, you can also initiate it by:
+```bash
+virsh console <VM_NAME>
+# for example
+# virsh console ubuntu-1
+```
+
+- Log in to your new VM using your credentials.
+
+##### 3. Validate your setup
+
+- Make sure the `root` disk has the expected space by running:
+```bash
+df -h
+```
+
+- If not, run:
+```bash
+growpart /dev/vda 1
+resize2fs /dev/vda1
+```
+
+##### 4. Configure networking for the VM
+
+As this guide is based on a newer Ubuntu, we use `netplan`, this may be different on different OS.
+
+- Open `/etc/netplan/01-network-config.yaml` in your favourite text editor:
+```bash
+nano /etc/netplan/01-network-config.yaml
+```
+
+- Insert this config, using your correct IP configuration, save and exit:
+```ini
+network:
+  version: 2
+  renderer: networkd
+  ethernets:
+    <INTERFACE>:
+      dhcp4: false
+      dhcp6: false  # Set to true if you want automatic IPv6 assignment
+      addresses:
+        - <IPv4_VM>/24  # Assign IPv4 address to the VM
+        - <IPv6_VM>/64  # Assign IPv6 address to the VM
+      routes:
+        - to: default
+          via: <IPv4_GATEWAY_HOST_SERVER>  # IPv4 gateway (host machine)
+        - to: default
+          via: <IPv6_GATEWAY_HOST_SERVER>  # IPv6 gateway (host machine)
+      nameservers:
+        addresses:
+          - 1.1.1.1  # Cloudflare IPv4 DNS
+          - 8.8.8.8  # Google IPv4 DNS
+          - 2606:4700:4700::1111  # Cloudflare IPv6 DNS
+          - 2001:4860:4860::8888  # Google IPv6 DNS
+```
+- Fix wide permissions on the config file:
+```bash
+chmod 600 /etc/netplan/01-network-config.yaml
+```
+
+- Check if the config has any errors:
+```bash
+netplan generate
+```
+
+- Apply the configuration:
+```bash
+netplan --debug  apply
+```
+
+- Verify by checking if IPv4 and IPv6 are assigned correctly and if they route:
+```bash
+ip -4 a
+ip -6 a
+```
+```bash
+ip -4 r
+ip -6 r
+```
+```bash
+# to ping through IPv6, use:
+ping6 nym.com
+```
+- You should be able to ping your new VM from a local machine:
+```bash
+ping <IPv4_VM>
+ping6 <IPv6_VM>
+```
+
+</Steps>
+
+Your VM should be working and fully routable. To be able to use it properly, we will create a direct SSH access to the VM.
+
+#### Configure VM SSH access
+
+<Steps>
+
+##### 1. Log in to your VM, update and upgrade your OS:
+- Log in to your server using as `root` or as a non-root user with `sudo` privileges
+```bash
+apt update; apt upgrade
+```
+
+##### 2. Generate new host SSH keys
+
+Since we used a `cloud-init` image without an SSH server, we need to generate SSH host keys for client authentication and server identity verification. All of them will be saved to this location: `/etc/ssh/<KEY>`.
+
+- Generate a new RSA host key:
+```bash
+ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
+```
+- Generate a new DSA host key:
+```bash
+ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
+```
+- Generate a new ECDSA host key:
+```bash
+ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key
+```
+- Finally, generate a new ED25519 host key:
+```bash
+ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key
+```
+##### 3. Restart the SSH service on the server
+- Run:
+```bash
+systemctl restart ssh.service
+```
+
+##### 4. Check if the SSH serice is active
+- Run:
+```bash
+systemctl status ssh.service
+```
+
+##### 5. Create file `~/.ssh/authorized_keys` and add you public key:
+- Create `.ssh` directory:
+```bash
+mkdir ~/.ssh
+```
+
+- Open with your favourite text editor:
+```bash
+nano ~/.ssh/authorized_keys
+```
+- Paste your SSH public key, save and exit
+
+- In case of non-root, setup a correct ownership and permissions:
+```bash
+chmod 600 ~/.ssh/authorized_keys
+chmod 700 ~/.ssh
+chown : ~/.ssh
+```
+
+##### 5. Test by connecting via SSH
+
+- Now you should be able to connect to the VM directly from your local terminal
+```bash
+ssh root@<IPv4> -i ~/.ssh/your_ssh_key
+```
+</Steps>
+
+Now your VM is almost ready for `nym-node` [setup](../../nym-node/setup). Before you proceed, ssh in and [configure all prerequisities](../vps-setup#vps-configuration) needed for `nym-node` installation and operation.

+# Nym Node Status API
+The Node Status API serves information about individual `nym-nodes` in the Mixnet, such as which role they are operating in, statistics about them, services such as Network Requesters, as well as summaries of the state of the Mixnet.
+
+We recommend that developers building applications such as explorers or analytics interfaces about the Mixnet run their own instance of the API, in order to promote a robust network of downstream services, and spread the load of API calls amongst as many endpoints as possible.
+
+You can find build and operation instructions in the [docs](https://nym.com/docs/apis/ns-api).
