Re: [Samba] Samba and ufw




Rowland,

OK. Should I delete these lines?

diff yours mine
63d62
yours# -A ufw-after-logging-output -m limit --limit 3/min --limit-burst 10
-j LOG --log-prefix "[UFW ALLOW] "
 85,87d83
yours# -A ufw-before-logging-forward -m conntrack --ctstate NEW -m limit
--limit 3/min --limit-burst 10 -j LOG --log-prefix "[UFW AUDIT] "
yours# -A ufw-before-logging-input -m conntrack --ctstate NEW -m limit
--limit 3/min --limit-burst 10 -j LOG --log-prefix "[UFW AUDIT] "
yours# -A ufw-before-logging-output -m conntrack --ctstate NEW -m limit
--limit 3/min --limit-burst 10 -j LOG --log-prefix "[UFW AUDIT] "
 92c88
----------------------------------------------------------------------------

Edit these lines to be the same as yours

yours# -A ufw-logging-deny -m conntrack --ctstate INVALID -m limit --limit
3/min --limit-burst 10 -j LOG --log-prefix "[UFW AUDIT INVALID] "
mine# -A ufw-logging-deny -m conntrack --ctstate INVALID -m limit --limit

You have a few lines I don't have, I have a line that you do not have, but
it is very similar to one of yours and I am allow access to Samba from
anywhere, but you are limiting it to '192.168.x.x'

Are the numbers between the lines part of the line above? How do I make the
changes?

Thanks for your patience. We will resolve this issue yet.

Regards,
Marty

Running 'diff' against your rules and mine produces this:
