Hi.
I have a problem and I cant find error in my code. My circleci I don't want to make a connection with my vps.Its error message:

#!/bin/bash -eo pipefail

ssh -T root:51.91.252.150 < bin/deploy/pre_deploy.sh

ssh: Could not resolve hostname :*********: Name or service not known

Exited with code exit status 255

CircleCI received exit code 255

This looks very similar to this issue: Getting an error when trying to deploy using SCP

Please perform the troubleshooting steps discussed there, and double check your firewall rules.

Thank you for help.I read all article. But I have turn off my firewall.And I don`t know where I have problem.

One immedaite problem that I see is this:

This is not a valid syntax for SSH. It should be root@ not root:

I change my code to connect with vps form :

root:51.91.252.150

on

root@51.91.252.150

And I have new message error :

The authenticity of host '************* (*************)' can't be established.

ECDSA key fingerprint is SHA256:Vz0ar5G9YVgwWmG8FXCBAVoCSZAwKUoIcjkqi5oSNkk.

Are you sure you want to continue connecting (yes/no)?

Too long with no output (exceeded 10m0s): context deadline exceeded

Are you sure you want to continue connecting

This means that the remote host does not appear in known_hosts. To fix this, you can SSH into your CircleCI instance (see the docs), install the private key, do a manual SSH operation, say “yes” to the question, and get a connection to your remote host. Then disconnect immediately, and your known_hosts should have a new line.

Copy this line back to your dev machine, and then commit it to your repo. Then in your CircleCI config you can append it your known_hosts file, to prevent the question coming up again.

Update

There is an alternative approach, which appears to be what you have tried:

ssh-keyscan -H 51.91.252.150 >> ~/.ssh/know_hosts

You have a typo in your target file - this should be known_hosts. I personally prefer my approach, since I believe it guards against DNS poisoning, but it is going to be easier in your case to fix what you have.
