ssh2 | SSH2 client and server modules | Runtime Evironment library

The origin of the ssh2 package is PECL but it's repackaged by most distribution of PHP e.g. Ubuntu, Arch Linux, MS-Windows.There's only some very, VERY edge cases where it makes sense to install directly from PECL.

You're not going to make any headway until you have a running SFTP server (any mainstream Linux distro will suffice, SFTP is installed automatically with ssh).

It might share three letters with the protocol you are currently using but SFTP is very different from FTP. However it should be possible (for example) to create functions with one-to-one mappings to what you are currently using, however as the FTP functions are part of the core PHP distribution, you'll need to use different names.

You can use a promise to communicate back the final result:

This is most likely due to incorrect content of the KnownHosts file. Therefore, make sure that the KnownHosts file is correct with the content of id_rsa.pub(public file), if it is incorrect, you will need to add it after Host name or IP address. Such as;

HOSTNAME ssh-rsa AAAAB3NzaC1yc...

I've made a lot of tests and found the problem: by default, to connect to the target hosts, Ansible uses the smart connection plugin. In my case, the smart plugin leads to the use of the native OpenSSH.

Forcing manually the use of the paramiko connection plugin solves the problem, everything is OK (paramiko is a Python implementation of OpenSSH). Just need to add the instruction connection: paramiko at the needed level:

Your script probably shouldn't start ssh-agent; it should make use of an ssh-agent that's already running. That way, the user is responsible for starting a single agent that can be used by multiple invocations of the script.

The simplest thing you can do, though, is simply add either

Judging by the log, you have problems installing a transitive dependency ssh2, it uses an assembly from sources for a specific platform and this requires a package node-gyp that is not installed on your system, try installing it first

Because the SFTP code is all async, your function is probably returning before the .then() has run and your execution environment is ending before the it gets to upload the file. You should make your helloWorld function async and await and return a response before returning:

You have a private key in rarely used ssh.com format. Paramiko does not support it. You have to convert it to the OpenSSH format.

You can use ssh-keygen like this:

I think it is easy to fix

you just don't have permission to modify the file on your server with your current user.

add the user as the directory owner:
