Bonjour à tous,
Je débute avec fail2ban et j'aimerais traiter la ligne de log suivante :
```bash
{
"reqId":"nkUHMTIR238pHO8fZ4E3",
"level":2,
"time":"January 29, 2018 21:25:30",
"remoteAddr":"192.168.1.1",
"user":"--",
"app":"core",
"method":"POST",
"url":"\/login?user=arthur575",
"message":"Login failed: 'arthur575' (Remote IP: '192.168.1.1')",
"userAgent":"Mozilla\/5.0 (X11; Linux x86_64; rv:52.0) Gecko\/20100101 Firefox\/52.0",
"version":"12.0.5.3"
}
```
Ainsi, je me suis documenté et voici ce que j'en ressors pour le fichier /etc/fail2ban/filter.d/nextcloud.conf
**Est-il nécessaire de mettre le caractère '\'** au niveau de la ligne ci-dessous "message":"Login failed: '.*' \(Remote IP: '<host>'\)" ?
```bash
[Definition] 
failregex = {
"reqId":".*",
"level":2,
"time":".*",
"remoteAddr":".*",
"user":".*",
"app":"core",
"method":".*",
"url":".*",
"message":"Login failed: '.*' \(Remote IP: '<host>'\)",
"userAgent":".*",
"version":".*"
}
```
Merci par avance.
Bonne journée.
