SFTP Email notification on login
I've not been having any luck at all finding the answer to this, so thought I'd ask here: is there any way to get my servers to send an email when someone logs in through SFTP? I was able to get that to work with SSH using a simple bit of script in /etc/profile, but I can't find anything on Google about doing that with SFTP at all.
The OpenSSH version on my server is 5.2p1 running on FreeBSD 8.0. Any way to get the server to execute any command on SFTP login will be enough for me to get this set up.
Any help is very much appreciated.
