Command & file logging for sftp/scp/ssh

[the.root]

So I'm trying to increase the logging on my servers so I can tell what some people are doing (and breaking).

I basically want to log all sftp file transfers (basic information on it). All scp file transfers (basic information as well). And ALL ssh commands that was sent without opening a tty (IE they arent passed to .sh_history).

I figured out the sftp by adding the -l INFO line to :
Subsystem sftp /usr/local/libexec/sftp-server -l INFO

I think I've found a few options for ssh - i'm not sure yet, I still want to look into. What I'm really stumped on is the scp logging. It doesn't log with the sftp and I cant seem to find a way to get log information on files transferred using the scp app on the server side. I would be really surprised if openssh didn't have the scp & ssh cmd logging built into it somehow. This has to be a pretty common requirement of sysadmins, especially ones who have to conform to PCI specs (another main reason why i need to do this).

If anyone has any suggestions on how to go about doing this, please let me know!!

Thanks!
