I've noticed some time ago that most of my Linux devices have two IP addresses in my local network, on a single wlan interface (192.168.1.127 and 192.168.1.128 in this screenshot)
Both of them work - I can ping those addresses from another device in a local network.
Why is that so? Why two addresses for one network interface? And how?
Lessons learned so far from this round of instance shenanigans...
The storage on Oracle Cloud Free Tier (on x64 instances) is pretty terrible.
Hetzner has really great inbound network speed, but horrid outbound. I tested both in Helsinki and Hillsboro. When I sent files to my instances, it would be mega fast. When I tried to download files from my instances it would be 200-300Kbps. I have symmetric 1Gbps fiber, downloading a Debian ISO from debian.org ran at megabytes per second speeds.
Digital Ocean is expensive compared to the above two, but it's fast, real fast.
We have a device that runs embedded linux and we manage wifi connectivity via the wpa_supplicant application. We have clients that are wanting to connect them to a Cisco IPSK network.
It’s been a long time since I did networking, and IPSK + radius is something I only vaguely know about.
But I can’t find anyone talking about the two in the same article.
As far as I can tell from Cisco’s docs, it’s just a normal PSK connection on the client side. All the magic for IPSK seems to be on the Cisco controller side, letting networks set individual or group passwords for PSK connections based on MAC address.
But that’s all an educated guess after reading the below page.
