So glad cat-X crossover cables died out. Hard to believe interfaces some years ago didn't support switching pairs.
That and stateless ipv6 autoconfig makes it actually possible to quickly and directly transfer anything, as opposed to having to find a USB Flash big enough, then find out there's a >=4GiB file there, then do a backup, format it to something both computers understand, then copy everything twice.
No need for anything special either, 1 liner and python and you have an HTTP server.
@zem They're not wrong, its really really convenient. Unbelievably so.
You're kind of meant to do extra configuration in a datacenter (like making sure the IPMI port is plugged in so as to not hijack the main connection), so yeah. I know someone who doesn't use netboot, or any kind of automation, not even DHCP, and installed and configured each server manually, in a not so small datacenter.
@lynne it is not about the extra work, it is simply that you likely forget the deactivation step especially if you deliberately bring up an interface without ip it should stay that way!
Userland knows best if the user wants to bring up an interface with v4 or v6 address or as bridge and can enable autoconf as needed, without regular users noticing. there is no need to have that enabled by default in the kernel and therefore it is a risk in my opinion.
