RE: repeated port 21 attempts

I'm getting port 21 connection attempts every 5 minutes from about
half a dozen of my network users. These attempts are repeating
regularly with one computer sending out 1500+ attempts a day. I have
not seen this before and I'm wondering if anyone else here has seen a
client behave this way before?
Sounds like FTP and SSH attacks that are opportunistically launched by
Romanian attackers to date, simple brute force and a few other hacking
exploits. It's a consistent issue we've seen globally for many months now.
