I installed CentOS 7.4 (1708) Minimal on a fresh Raspberry Pi 3 without issues. But I am struggeling with SSH connections, although each time the network is reachable from the Raspberry:
- If a keyboard or a keyboard USB dongle is attached to the Raspberry at boot time SSH works perfectly fine
- If the keyboard dongle is never attached, no SSH connection can be established with a
Network error: Connection timed out
- If the keyboard dongle is attached after booting, the keyboard works, but the Raspberry can still not be connected to via SSH
I had a similar problem with a x86_64 server and could solve it allowing the BIOS to boot without a keyboard. But here the Raspberry boots correctly, but still does not allow any SHH connections.
Any suggestions what I could do?
