SFTP failing – due to using an outdated authentication algorithm or protocol?

Thanks, looking forward to try it out. I found the tar archive output being pretty good workaround as well.

I have a similar issue with a server that has a very old ssh/sftp server. It seems that Publii has changed something in the sftp protocol/library between version 0.35.3 and 0.39.1. In the older version the sftp connection works, in the newer it doesn’t. The “Test connection” gives the following Error message:

Error! Application was able to connect with your server but was unable to store files. Please check file permissions on your server.

Using scp e.g. from Mobaxterm, the connection works fine. Looking at the sshd logs on the server it says:

fatal: no kex alg

It seems that Publii 0.39.1 is more restrictive in the KexAlgorithms allowed. It should allow older kex algorithms like “diffie-hellman-group-exchange-sha1”.  Could you check what has been changed and if this can be reverted? Thanks.

I did a comparison with the plain sftp package alone.

The client is the same MacOS, same account and same ssh key.

Server is the same OpenBSD, same account.

The sample program with the package alone authenticates fine and is able to access the server.

Publii attempting the same fails as described above.

Could there be something in the configuration object Publii hands out to the library that forces it to use an incompatible algorithm ssh-rsa instead of ssh2 RSA. ?

npm install ssh2-sftp-client

let Client = require(‘ssh2-sftp-client’);

const fs = require(‘fs’);

let sftp = new Client();

sftp.connect({

<span class=”Apple-converted-space”>  </span>host: ‘kb.example.com’,

<span class=”Apple-converted-space”>  </span>port: ’22’,

<span class=”Apple-converted-space”>    </span>username: ‘kb’,

<span class=”Apple-converted-space”>  </span>privateKey: fs.readFileSync(‘/Users/kb/.ssh/id_rsa’)

}).then(() => {

<span class=”Apple-converted-space”>  </span>return sftp.list(‘/var/www/htdocs/kb.example.com’);

}).then(data => {

<span class=”Apple-converted-space”>  </span>console.log(data, ‘the data info’);

}).catch(err => {

<span class=”Apple-converted-space”>  </span>console.log(err, ‘catch error’);

});

node sftp.js
