An in depth look at scanning with Nmap, a powerful network scanning tool.
Les 2 premiers caractères indiquent le type d'interface. Pour nous, le plus courant sera :
- en : Ethernet
- wl : Wireless Lan
Ensuite, le suffixe. Les plus souvent vus sont :
- oXXX : Les cartes intégrées (onboard)
- sXXX : Les cartes qui sont branchables à chaud (souvent dans le cadre VM VMWare) - fN permet pour une carte multifonction de différentier les ports
- pXXsYY : Les cartes connectées en PCI, avec la localisation matérielle du BUS et du SLOT (en Décimal) - fN permet pour une carte multifonction de différentier les ports
- pXXsYYuZ : Les cartes connectées en USB, avec la localisation matérielle du BUS et du SLOT (de la carte USB connectée en PCI, en décimal), et uZZ avec le numéro du périphérique USB - fN permet pour une carte multifonction de différentier les ports
Arweave makes information permanence sustainable.
Arweave is a new type of storage that backs data with sustainable and perpetual endowments, allowing users and developers to truly store data forever – for the very first time.
As a collectively owned hard drive that never forgets, Arweave allows us to remember and preserve valuable information, apps, and history indefinitely. By preserving history, it prevents others from rewriting it.
Netpoll is a high-performance non-blocking I/O networking framework, which focused on RPC scenarios, developed by ByteDance.
RPC is usually heavy on processing logic and therefore cannot handle I/O serially. But Go's standard library net is designed for blocking I/O APIs, so that the RPC framework can only follow the One Conn One Goroutine design. It will waste a lot of cost for context switching, due to a large number of goroutines under high concurrency. Besides, net.Conn has no API to check Alive, so it is difficult to make an efficient connection pool for RPC framework, because there may be a large number of failed connections in the pool.

My traceroute, originally named Matt's traceroute (MTR), is a computer program which combines the functions of the traceroute and ping programs in one network diagnostic tool.[2]
MTR probes routers on the route path by limiting the number of hops individual packets may traverse, and listening to responses of their expiry. It will regularly repeat this process, usually once per second, and keep track of the response times of the hops along the path.
