Sometimes I get in the bundler console an error like this: So far, I could get this script in react-native retrieve the time in ms for the first IPs if they are responsing. Im trying to ping all LAN hosts on my network to find out which one is alive, to later find a raspberry pi which hosts a web service and the idea os to use my app with the raspberry web service. I know that if I connect the IP address of my router/modem I can see the connected devices as names, and their IP addresses, so I should be able to find this information somehow, I feel. Is there a way I can find which of my devices are currently connected to my internet network? Actually, All I really need is the number of devices. Also, neighbourhood uses functions that don't work in windows, like os.geteuid(), so I don't think it is compatible with windows. works() give the same error except that it says "'networks' doesn't exist". My python IDE suggests that these modules should exist with this structure. "module 'lanscan' has no attribute 'lanscan'" With lanscan I tried () and get the error message I tried using the modules neighbourhood and lanscan, but I can't get them to work on my machine. There aren't multiple people streaming on this network, so I know that isn't the problem, but if it is a devices problem, that might be on me to upgrade my internet. I would like to log, at the same time, how many devices are connected, just to make sure that the problem isn't that the internet only sucks once a certain number of devices are connected. I am performing a speed test every minute, and logging it to a text file. This is part of a bigger project to prove to my ISP that my internet sucks. Turns out it was a cockpit error, but the email clearly addressed my problem and contained everything I needed to use LanScan correctly.I'm trying to write a script to check how many devices are connected to the internet. OK, so I probably won't always get the level of support every time, but I was happy. On a Sunday, I got a response in 6 minutes. Though I had a problem, so I emailed the developer (accessed through the app's Help menu). Recently, I upgraded to Catalina and tried to do a scan on a machine with multiple interfaces. This has made it so simple to find IP addresses for devices I cannot quickly get to or which don't have a way to view it. It's been fantastic to take a quick inventory of the machines on my lans.Įventually, I had a need for the additional information so I ponied up the six dollars for the pro version (buy in-app, not the separate version). I picked up a copy a few years ago and used LanScan in the "free" mode. Great utility if you have more than a few machines or lans to support Advanced LAN Scanner is a nice, free Windows software, that is part of the category Networking. → The free trial only obfuscate results, but display them all : if a column is blank or empty, buying a Pro In-App feature won't make any new result appear. Scan your network and get information about ports and PCs. → Some hostnames, comments, TCP ports or IPv6 addresses might be obfuscated in free trial Restrictions in free trial version compared to Pro In-App Purchase: → Go in Help → In-App purchases for more details → Like IPv4, some features in free trial and full unobfuscation through an In-App Purchase → Displays Link-Local (private) and Global (public) IPv6 addresses. → No limitation on the number of devices found ! → Hostname resolution: DNS, mDNS (Apple devices) and SMB (Windows devices) → Discover the SMB domain if any configured → Display the IP address, MAC address, hostname (4 max) and vendor associated → Scan public IP network ranges with Ping / SMB / mDNS packets → Scan your local network with ARP packets → Scan the IP range you like, from 1 IP to the whole IPv4 address space! → Auto-detection of configured interfaces: Airport, Ethernet, Virtual interfaces. LanScan is a simple and efficient IPv4 & IPv6 network scanner that discovers all active devices on any subnet: the local one, or any public subnet that you configure. ![]()
