chmod 740 on "/" -- root ?????
I am in need of help asap. I am completly new to Linux. Here is my problem. I logged in as root , I did this line:
chmod -R 740 /
It was literally changing the permissions for all file and directories, keep in mind I was using filezilla for this. After it went through them all I was disconnected from the server. It says "server unexpectedly closed network connection" when trying to log into the server via filezilla.
My goal was to limit access to all config files for I will be creating users and dictating user account. The users access a SFTP server for sensitive docs.
What did this command do that doesnt allow me to connect to the server?
Was there maybe a service that will need restarted? if so what can I do to restart it?
If anyone can help that would be greatly appreciated?
