By the way, I’d like to ban these tards scanning my server with fail2ban or something but apparently the only thing we can find about fail2ban and proxmox is about protecting the webgui port. Nothing for apache or to ban all the guys scanning ports (dunno if that would be very useful though).

The problem:fail2ban just not banning. Does nothing at all. My jail.local document:fail2ban-client statusIn the mean time in my auth.sign: |

What do you notice in fail2ban.record? Do you see this IP there? How numerous ranges sshd Present lt;IPgt; for the same IP? Make sure you take note, that it will banned only after 6 (maxretry ) attempt within 10 mins (findtime ) time screen. |

Now there's no any Found lt;IPgt; orBan lt;IPgt; messages. Furthermore,/var/record/fail2ssh.record is usually vacant. |

May this issue been caused because of /etc/ssh (rather of/etc/sshd ) on my machine? |

Nope. What do you find if you execute this: Tested with current 0.9.x version: Lines: 1 outlines, 0 disregarded, 1 matched, 0 missed. And this: |

Hmm. Unusual. No more ideas, except pyinotify backend does not function on your device (attempted 'polling'?). Can you puts fail2bar into DEBUG setting? Or if will not work, just start within DEBUG level (set it fall short2ban.conf and restart). And provide an excerpt of /var/log/fail2ban.record after some failure in auth.journal. Put on't forget to switch back if you are usually prepared. |

Here's the logs of fail2bar.record after log degree DEBUG has been established: Also, nothing was written to fail2ban.log since I established it's log degree to DEBUG. And I'm still getting spammed with bruteforce: |

Simply attempted to prohibit myself on my machine previously connected to VPN and getting into wrong password 6 instances and here's what I've obtained in my auth.sign :After getting into wrong security password 6 occasions in a line host dropped the connection, but after that I reconnected and nevertheless was capable to enter password. Hope right now there's some helpfull information that could assist you to discover out what's the concern. |
commentedDec 5, 2017
I'meters keeping with my think - something wrong with pyinotify. Tried 'polling'? Usually try once again with HEAVYDEBUG. BTW your version is certainly a little bit obsolete. Can you attempt some newer edition (gt;= 0.9.7, 0.10 or actually 0.11)? |

@JamesJGoodwin hi ! I have got the extremely same problem, but in my case, I have got a jail/rule watching an Apache HTTP Server accesslog, trying to determine users hitting difficult the internet web servers. It stopped working abruptly, no errors, no footprints in the wood logs. I even enabled the DEBUG setting but nothing at all seems. |

I has been about to open a fresh issue, but as this is usually equivalent to the one I'meters getting, I will adhere to up this. |

I've simply installed v0.10.2 dev1 from fail2ban.org and seems like I do properly and everything will be working just good, but there's simply no any bruteforce running presently on my server so I can't properly say if fail2bar functioning or not really. I'll be in touch.
What will be it? What are I intended to perform to enable it? @scampuza hi! It seems like not really fail2ban concern, but merchant's OS problem. Because previous my machine was organised in Russia with OpenVZ virtualization and fail2ban worked just fine presently there, but after that I relocated to OVH machine which has KVM virtualization and it's not really functioning on this type of device. Maybe there's simply some kind of Operating-system limitations, idk. |

'polling' will be another file-related backend fail2bar can use.
For illustration established it in prison.regional: |

Just tried to ban myself by getting into wrong password and still nothing occurs. fail2ban.log also is clear. None Found out orBar . I believe I should get in touch with my hoster'h support in this situation. |
mentionedDec 5, 2017
Well, I put on't think so. If fail2ban cannot bar (because of some cause like lacking kernel functions, etc.) you'll definitely obtain an error in fail2ban.sign. At minimum you'll observe an sshd Ban lt;IPgt; just before.Your situation - no failure will end up being regarded. This appears like the filter (backend):
Therefore I supposed that this is pyinotify-issue (probably the modified-event just does not achieve us). So either try out polling or make use of HEAVYDEBUG loglevel and discover what fail2bar.log said if log-file get actualized. |

Properly, enabling HEAVYDEBUG is usually caused extremely huge journal document(now it's dimension can be 332MM and it't still expanding). Is usually it normal behaviour? |
commentedDec 5, 2017
Yes. But do you find there something like Functioning on series. lt;IPgt; ? resp. something else that indicators pyinotify functions. |
commentedDec 5, 2017
After a several mins under HEAVYDEBUG sign file grew to become unreadable because of it's i9000 dimension(1,2GB). So I got to cease fail2ban, clear wood logs and then start it for a several seconds. Right now what I've obtained: Overall lines: 62018 Functioning on line equalled 2611 rangesGet a closer look on fail2ban.record |
left a commentDec 5, 2017
Arghhh. You path is incorrect: you observes /var/record/fail2ban.log rather of/var/journal/auth.record .BTW. Therefore also a great 'recursion' in heavydebug setting. :) |

Damn, shame on me. I'm so sorry I required so very much time from you. Now it's working, much thanks! |

Happy it works, thus I'michael shutting the issue. |

@sebres I'm having specifically the same concern as @JamesJGoodwin but with the difference that on Arc the file /var/log/auth.journal doesn'testosterone levels can be found everything is usually managed bysystemd andjournalctl exhibits efforts of brute push ssh assaults but fail2ban doesn't ban anything I'd attempting to ban myself but nothing.Issuing the following instructions: Any ideas on what adjustments should I make? |
commentedMay 31, 2018
I've seen the exact same problem on one of my machines. Removing the fail2ban.sqlite3 data source and restarting fixed the issue. |
commentedJun 1, 2018
@kirk86 I may be just incorrect config. You should fixed your backend forsshd prison tosystemd . File-backends (like pyinotify, polling as properly as auto) do montoring of the log-files just (not systemd-journals).And for check out it via fail2ban-regex you can make use of: |

@distler you're also right deleting persistent database does help during debugging. @sebres wrong config was furthermore an issue as well. I have got a questions though, will fail2ban need iptables.provider to be enabled and operating in order to work? |
left a commentJun 1, 2018
This is certainly system- resp. distribution-depended, age. g. debian's i9000 don't have got iptables.support (but nevertheless possess iptables subsystem). Some submission have various firewall techniques, and we've different activities to run with, y.h. firewalld, pf, iptables, nftables, etc. Which firewall you'll use can be your selection. And there can be also the issue what precisely is backed by your kernel. |

@sebres thanks a lot for the answer.
I presume that no matter what distro, the kernel support is pretty significantly the same across distros since the kernel is certainly one point that will be ubiquitous? |
left a commentJun 4, 2018
I find that I have to remove it, regularly; otherwise fail2ban just stops banning (just as you describe). Haven't been recently able to pin number down the source of the crime, even though. |
