My nightly logwatch report had a never before seen section last night, "barracuda spam firewall". I have not problem with the emails it noted as being rejected. But I've always thought of "barracuda" as a commercial product. I have neither configured nor enabled any barracuda software and "yum list '*barrac*'" comes up empty. What is this? Jon -- Jon

Hi all, Just out of curiosity: is there anything we can do, on the samba side, to counter the recent ransomware attacks? (or limit the damage done) I'm thinking like: limit the number of files per second a client (workstation) is allowed to edit, or some other smart tricks..? It would be nice if samba could be an extra layer of defense. Something perhaps a vfs module could help with..?
