SSH to live USB is not working after following steps in ArchWiki

Hello! I am having a problem getting ssh to work on my live Arch USB.

I followed the instructions in Install Arch Linux via SSH, and my live USB (connected to my Atomic Pi computer board, which does run on x86_64 architecture by the way ) --

• is booted

• is connected to the internet (as verified by ping)

• has passwd set for root

• has PermitRootLogin set to "Yes" in /etc/ssh/sshd_config

• and is actively running the sshd service (as verified by systemctl)

For some reason, when I try to access it from my other devices at it's local address with ssh root@10.0.0.X, it times out.

Any ideas what I can do to debug this?

Thank you!

Re: SSH to live USB is not working after following steps in ArchWiki

ping 10.0.0.X
nmap -p22 10.0.0.X
ssh -T root@10.0.0.X hostname

If the last command works, you can ssh, but not get an PTY. If you omit "hostname", you should™ get an interactive shell, but no prompt (the session is wating for input and if you enter "date" you should get the current date)

A recently very popular reason for a broken PTY situation has been colliding dhcpcd services (the global one and one or more on the specific NICs)

[*]is connected to the internet (as verified by ping)[/*]

You have console access to the device then? Post the output of `ss -tnlp` and then run `tcpdump -lnniany port 22` and try to connect over SSH.
