How do I connect to FTP using Filezilla?
I recently set up a one-click WordPres app. I need to update my .htaccess file but I can't seem to log in on Filezilla using my credentials.
You should be able to use your Linode's root credentials over port 22 to access FileZilla. If you're having trouble connecting, we have a more comprehensive Linode Community Questions post that I've linked to below that goes through some troubleshooting advice.
Did you set up an ftp server on your Linode? ftp is not set up by default on a Linode because it is (inherently) insecure.
Is (s)ftp open through your firewall?
