A while back, I was setting up a SFTP account for a developer and I used: Internal SFTP Settings
I don't know which file I put that in. How can I find it? Is there a way to search all my files in my server?
You need to put it in /etc/ssh/sshd_config (at least on CentOs, Debian and Ubuntu) Then restart the SSH server through /etc/init.d/sshd restart
