ransomware etc
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..?

wanna cry ransomware patch for samba-4.5.5
...really, i got 1 crypto attempt since Friday.
All others are blocked.
If you use postfix als mail relay. Read ; http://www.postfix.org/POSTSCREEN_README.html
If you setup postscreen like this this stops about 95% of all problems.
Add this part.

Again, questions ask.
### Before-220 tests (postscreen / DNSBL)
postscreen_greet_banner = $myhostname, checking blacklists, please wait.
postscreen_greet_wait = 3s
postscreen_greet_ttl = 2d

In the early days I of course was free with my email and used it everwhere.
Fast forward to 2012, some 15 years later.
woof..the amount of spam sent to me has always just kept getting worse
and worse.
On my centos 5 server I just used sendmail with spamassassin and it
