But what is the username@host at the beginning for? That command won't work.

Code:

$ username@machine_name 'ls dirname'
bash: username@machine_name: command not found
$

apache is the file group. apache needs write permissions to the folder to mkdir inside it. so you change the group to apache, and give apache write-access.


In terminal. You only need to do it once. You don't need an alternative to ssh. You need to give ssh the things it needs to work without a password. It'd also help to run ssh in the first place.

You did get ssh working without a password, yes? If not, you're going to have to do so, because there's no way for a user to interactively type in a password over CGI.
