Re: How to stop logging ICMP_IN, UDP_IN, UDP_OUT blocked messages in kern.log?

@Sergio ># If a log line matches it will be ignored, otherwise it will be reported This means for me the log line is already appearing, but it will be ignored for processing (logscanner). It does not mean the the log line will not be logged due to matching with regular expression. Because the first ...

Re: How to stop logging ICMP_IN, UDP_IN, UDP_OUT blocked messages in kernel.log?

Hello, Since csf/lfd is very important for my server security, I would like with a monitoring script to ensure that csf and lfd are both running and operational. Is there a recommended way to do this ? I am running CentOS 7. I am thinking about: - either parsing the output of command "systemctl...

Re: csf autoupdate and From/To fields in email

csf autoupdate and From/To fields in email

Hello, I discover the csf autoupdate function (AUTO_UPDATES = "1" in csf.conf). But I have few questions : 1) The update is triggered daily with /etc/cron.d/csf_update. I only receive update report mail when there is an update, this is good. But how does this works? The cron daemon only se...

So my initial suggestion is still valid I believe. This alert would let me know if there is any FTP activity for a given IP for eac...

Alert for successful FTP login per day and per IP

Hello, Is this possible to receive an alert for a successful FTP login? The alert should be issued only once per day and per IP.
