Owncloud and Fail2ban

I have owncloud in apache behind nginx. I try to ban bad guys by Fail2ban in nginx server.
All is ok, log comes from owncloud, with real IP, and is reading by fail2ban.
But all is missed all the time… I try many regex but with no results.

The line of log
Feb 27 21:01:19 OWNCLOUD1 ownCloud[30242]: {core} Login failed: ’’ (Remote IP: ‘xx.xx.xx.xx’)

I try a lot, The last
’.’ Login failed: ’.’ (Remote IP: ’<HOST>) ’.*’

It’s not my first fail2ban, but…
Thanks a lot for your response.

Hi @globo

probably you should use something like the following:

failregex = ^.*Login failed.*Remote IP:.<HOST>..*$

Hi theMiddle, thanks for your quick response
But always trouble after I have changed owncloud.conf in filter.d,

Running tests

Use failregex filter file : owncloud, basedir: /etc/fail2ban
Use log file : /var/log/clients/
Use encoding : UTF-8


Failregex: 0 total

Ignoreregex: 0 total

Date template hits:
|- [# of hits] date format
| [341] (?:DAY )?MON Day 24hour:Minute:Second(?:.Microseconds)?(?: Year)?

Lines: 341 lines, 0 ignored, 0 matched, 341 missed [processed in 0.02 sec]

but i verify in the log file,
Mar 1 08:42:23 OWNCLOUD1 ownCloud[34887]: {core} Login failed: ‘essai’ (Remote IP: '’)

Ok I find the correct regex
failregex = .: {core} Login failed: ’.’ (Remote IP: ’<HOST>’)
