How do I see does anyone when connecting to a Linux server with winscp?what folders go, what the file transfer?how to monitor access of this program on different servers???Because when I give command :vi /var/log/secure ,appear just that : Aug 23 09:17:47 dsf sshd[11790]: Accepted password for xxx from x.y.z.t port 1274 ssh2
Aug 23 09:17:47 dsf sshd[11790]: pam_unix(sshd:session): session opened for user xxxx by (uid=0)
Aug 23 09:17:47 dsf sshd[11792]: subsystem request for sftp

You should seek advice with your SSH server provider.
