Script that crawls the network and maps out all the hosts. Also shows whether or not you have root access. Can easily be tweaked to show more metadata. It’s depth-first recursive because I was too stupid to figure out breadth-first iterative. Current iteration requires 3.9GB RAM to execute; I’ll try to improve that.

Code

/** @param {NS} ns **/export async function main(ns) {
 let home = new Object();
 let nodeMap = new Map();
 home.name - [home.name]  = ns.getHostname();
 home.parent = null;
 home.adjacents = ns.scan(home.name); - [] 
 nodeMap.set(home.name - [home.name] , home);
 discover(ns, home, nodeMap);
 printMap(ns, home, nodeMap, "");
}

/** @param {NS} ns **/function discover(ns, node, nodeMap) {
 node.adjacents.forEach(nodeName => {
 if (nodeMap.has(nodeName)) {
 return;
 }
 let newNode = new Object();
 newNode.name - [newNode.name]  = nodeName;
 newNode.parent = node;
 newNode.adjacents = ns.scan(newNode.name); - [] 
 nodeMap.set(newNode.name - [newNode.name] , newNode);
 discover(ns, newNode, nodeMap);
 });
}

/** @param {NS} ns **/function printMap(ns, node, nodeMap, indent) {
 ns.tprintf(indent + "%s%s", node.name - [node.name] , ns.hasRootAccess(node.name) - []  ? "(Y)" : "(N)");
 nodeMap.delete(node.name); - [] 
 indent = adjustIndent(indent, node, nodeMap);
 printIndent(ns, indent, node);
 
 node.adjacents.forEach(adjacentName => {
 if (nodeMap.has(adjacentName)) {
 printMap(ns, nodeMap.get(adjacentName), nodeMap, indent);
 }
 });
}

/** @param {NS} ns **/function printIndent(ns, indent, node) {
 if (node.adjacents.length > 1) {
 ns.tprintf(indent + "|");
 }
}

function adjustIndent(indent, node, nodeMap) {
 for (let i = 0; i < node.name.length - [name.length]  - 1; i++) {
 if (i === 0 && hasMoreSiblings(node, nodeMap)) {
 indent += "|";
 } else {
 indent += " ";
 }
 }
 return indent;
}

function hasMoreSiblings(node, nodeMap) {
 let result = false;
 if (node.parent === null) {
 return result;
 }
 node
 .parent
 .adjacents
 .forEach(adjacent => {
 if (nodeMap.has(adjacent)) {
 result = true;
 }
 });
 return result;
}
