banisher's Issues

[Tuto] Création d'un service (Debian / Ubuntu)

Petit tuto sur la création d'un service :

nano /etc/systemd/system/banisher.service

[Unit]
Description=Banisher Service

[Service]
Type=simple
Restart=always
RestartSec=1
User=root
ExecStart=/home/banisher/banisher

[Install]
WantedBy=multi-user.target

Pour le démarrer :
systemctl start banisher

Pour le lancer au boot :
systemctl enable banisher

Please update binary to latest

Binary seems to be out of date with latest code source.

Could you create a new binary release?

Récupération IP et hostname ?

Hello,
Je voudrais savoir si c’était possible de récupérer le hostname dans la ligne que catch banisher dans les logs par exemple pour pure-ftpd.
Je m'explique :
Dans les logs messages, parfois pure-ftpd ne récupère pas l'ip mais le hostname de la machine qui se connecte par exemple :

May 14 18:26:56 zeee pure-ftpd: (?@37.122.179.131) [WARNING] Authentication failed for user [root]
May 15 08:51:20 zeee pure-ftpd: (?@39.43.14.232) [WARNING] Authentication failed for user [Admin]
May 15 17:15:18 zeee pure-ftpd: (?@torseedslu) [WARNING] Authentication failed for user [anonymous]
May 17 07:23:25 zeee pure-ftpd: (?@wsip-64-207-236-98.tu.ok.cox.net) [WARNING] Authentication failed for user [www-data]

Je voudrais rajouter la règle suivantes :

  - name: pure-ftpd
    match: pure-ftpd:.*Authentication failed*
    IPpos: 0

Est-ce possible que cela fonctionne ou pas du tout ? ou il faut faire une modification sur banishier ?

Merci 👍

Ban ne fonctionne pas ?

Hello,
Je viens de voir que dans banisher les IPs ban essaient de se connecter quand même par exemple:

Je vois biens l'ip bannie dans iptables -L mais à la fin d'iptables et non au début IPTABLES -A à la place de -I

Je fais iptables -I INPUT -s 137.74.42.235 -j DROP . Plus de connexion de l'ip

Je fais le test avec la 2ème IP : 104.131.57.64

Plus de connexion avec l'ip 104.131.57.64 ensuite.

Je ne sais pas si c'est bien la root cause mais possible de faire la modification ?

Merci.

Feature request.

Hi! Thanks for this awesome package!

I have a couple of feature requests.

ability to unban an IP based on rule name (similar to fail2ban feature)
a way of running a pre/post script on ban. (for example, to send HTTP POST notification)

Again, thanks.
