Fifteen is an M2 MBA and Sellotape is a 2019 iMac. Both running Sequoia.
Before Sequoia I was able to log in to either machine from the other. Now it fails:
Fifteen:~ mnewman$ ssh sellotape
ssh: connect to host sellotape port 22: Operation timed out
Unless I use local appended to the hostname:
Fifteen:~ mnewman$ ssh sellotape.local
Last login: Wed Oct 2 15:49:39 2024 from fe80::4d5:db02:81d6:74d5%en0
Sellotape:~ mnewman$
I don’t know enough about networking to understand why this works. Can anyone explain?
——– verbose logging below ——–
Fifteen:~ mnewman$ ssh -vv sellotape
