Hi Michael thanks for answer, from "fail2ban-regex --print-all-missed" i have the following output when i test ssh access (Jun 25 19:19:26 localhost sshd[3143]: Connection closed by 172.16.45.1 [preauth]) but there is no action from the firewall to block this ip address. I'm testing this on virtual machine with 172.x.x.x. ip. This virtual machine is on my laptop with 192.168.0.x ip using the VMware i have install the fial2ban on centos with 172.xxxx ip.user3523605– user35236052015-06-25 23:22:16 +00:00Commented Jun 25, 2015 at 23:22

Are there other lines that the filter.d/sshd.conf finds, maybe it's not finding enough lines to ban (6)? Is it able to find ipset command?Michael Grant– Michael Grant2015-06-26 01:28:45 +00:00Commented Jun 26, 2015 at 1:28

No, sorry, that's confusing. Look at your action that you stated above, you have "action = firewallcmd-ipset". This action uses the file named "action.d/firewallcmd-ipset.conf" (relative to your fail2ban conf directory). This conf file uses the ipset command to tweak the firewall. Is fail2ban able to execute the ipset command? Can you execute it from the command line? Is there anything in the fail2ban log file that might give a clue as to why it's not doing anything?Michael Grant– Michael Grant2015-06-28 20:19:56 +00:00Commented Jun 28, 2015 at 20:19

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
