Kimai
Fail2Ban per gli accessi
Un plugin compatibile con Fail2Ban che registra i tentativi di autenticazione falliti
Kevin Papst
A Kimai plugin, which logs an error message for every failed login attempt to a dedicated logfile.
This logfile can be analyzed by fail2ban to block access and prevent authentication attacks.
Fail2Ban configurations
You should know how to use and configure fail2ban, we cannot help with that part!
Having said that, here are some possible rules for your fail2ban configuration.
First the Kimai specific filter:
#/etc/fail2ban/filter.d/kimai2.conf
[Definition]
failregex = fail2ban.ERROR: <HOST> \[.*\] \[.*\]$
And the additional jail.local for Kimai:
#/etc/fail2ban/jail.local
[kimai2]
enabled = true
filter = kimai2
logpath = /var/www/kimai2/var/log/fail2ban.log
port = http,https
bantime = 600
banaction = iptables-multiport
maxretry = 3
Now touch the file to make sure it exists:
touch /var/www/kimai2/var/log/fail2ban.log

Installazione
Copia file
Extract the ZIP file and upload the included directory and all files to your Kimai installation to the new directory:
var/plugins/Fail2BanBundle/The file structure needs to look like this afterwards:
var/plugins/
├── Fail2BanBundle
│ ├── Fail2BanBundle.php
| └ ... more files and directories follow here ...Cancella cache
After uploading the files, Kimai needs to know about the new plugin. It will be found once the cache was re-built. Call these commands from the Kimai directory:
How to reload Kimai cache
bin/console kimai:reload --env=prod
It is not advised, but in case the above command fails you could try:
rm -r var/cache/prod/*
You might have to set file permissions afterwards:
Adjust file permission
You have to allow PHP (your webserver process) to write to var/ and it subdirectories.
Here is an example for Debian/Ubuntu, to be executed inside the Kimai directory:
chown -R :www-data .
chmod -R g+r .
chmod -R g+rw var/
You might not need these commands in a shared-hosting environment.
And you probably need to prefix them with sudo and/or the group might be called different from www-data.
Aggiornamenti
Updating the plugin works exactly like the installation:
- Delete the directory
var/plugins/Fail2BanBundle/ -
Execute all installation steps again:
- Copia file
- Cancella cache
