I'll set up SSH key authentication to that server. Let me first check if there's already an SSH key on this machine.

An SSH key already exists. Let me copy it to the remote server using `ssh-copy-id`.

Key installed. Let me verify passwordless login works:

Done. SSH key authentication is set up and working. You can now connect to `148.251.51.153` without a password: ``` ssh root@148.251.51.153 ```

can 148 conn to other servers ex hansen.danmarcrm.com?

Let me check if 148.251.51.153 has an SSH key and can connect to hansen.danmarcrm.com.

No SSH key exists on 148. Let me generate one and test connectivity to hansen.danmarcrm.com.

Key generated. Now let me check what hansen.danmarcrm.com resolves to and try to copy the key there.

Connection timed out — 148.251.51.153 **cannot reach** hansen.danmarcrm.com (5.161.122.178) on port 22. This could be: 1. **Firewall on hansen** blocking incoming SSH from 148.251.51.153's IP 2. **Network/routing issue** between the two servers 3. **SSH listening on a different port** on hansen Want me to check if this server (the one we're on now) can reach hansen, or check if there's a firewall rule that needs updating?

I allowed the ip in firewall, should work

Let me test again.

Firewall is open now — connection goes through but the key isn't authorized yet. Let me install 148's key on hansen.

Can't SSH to hansen from here either with password. Let me check if this machine already has access to hansen.

This server can't connect to hansen either. It looks like hansen has password auth disabled (only accepts keys). Do you have another way to access hansen (e.g. a control panel, or another server that already has key access) so I can add 148's public key to its `~/.ssh/authorized_keys`?

yes

Great, here's 148's public key — add it to `~/.ssh/authorized_keys` on hansen: ``` ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHVosXCEZyG5jEs4QDUoA71nh+MepIhf7yKRW7MABcR5 root@Ubuntu-2204-jammy-amd64-base ``` Let me know once it's added and I'll test the connection.

done

Working. 148.251.51.153 can now connect to hansen.danmarcrm.com (hostname: slpx2) without a password.

from the local comp can't connect by ssh root@148.251.51.153

Let me check what's going on with SSH on 148.

Only this server's key is there. What's your local machine's public SSH key? You can find it by running this on your local computer: ``` cat ~/.ssh/id_ed25519.pub ``` or ``` cat ~/.ssh/id_rsa.pub ``` Paste it here and I'll add it to 148's authorized_keys.

ssh-rsa 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 dan@Dans-MacBook-Air.local

Done. Try connecting from your Mac now: ``` ssh root@148.251.51.153 ```
