After creating an ssh-keygen on windows, I cannot access my RPis from Manjaro

I’m creating a pi-cluster using 3 Raspberry Pis, after successfully accessing them with ssh on windows, I get an error message with manjaro: ssh: connect to host port 22: Connection refused.

I have tried turning on sshd with systemctl and allowing ssh with ufw and even the specific ip adresses.
My guess is because I have already created a fingerprint or keygen in windows, I cannot access it on linux, it can also be a firewall issue

If you connect from another machine (Manjaro vs Windows) you need to either copy over your ssh key from the windows machine to the Manjaro machine, or create a separate key-pair from the Manjaro machine.

Do you use putty on windows ?
Have you copied the keys to manjaro ?
Did you convert the putty-keys to ssh-keys ?

I have zero experience with cluster computing but this message indicates your ssh daemon is not running.

Although I do not fully understand what all he has done in the OP I tend to agree. What I have seen in the past if keys are involved you would see something like this:

ssh remoteuser@remotehost
    Permission denied (publickey).

If one tries to ssh and login as root you would get

ssh: connect to host port 22: Connection refused

Thanks for the replies, I’ll try the first two comments. Also, my ssh daemon is running:

     Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled; vendor pres>
     Active: active (running) since Thu 2021-10-07 04:21:52 AEDT; 8h left
   Main PID: 782 (sshd)

             └─782 "sshd: /usr/bin/sshd -D [listener] 0 of 10-100 startups"

I’m also not sure why my issue was moved into the “ARM Technical Assistance” section. I’m accessing my Pis through ssh on an x86 desktop

I thought it was a Arm issue. I can move it back?

What’s done is done, it’s fine

How do I do that? I used ssh on PowerShell

10

You have any ideas how to do so?
My solution is just to delete the keygens on windows

putty uses its own form of keys. But it is possible to convert them to open-ssh-format

Or you could use putty under manjaro (AUR)
