Borgmatic mit Hetzner Storagebox Irgendwie hab ich mein gesamtes Mail Archiv beim Anpassen eines Volumes gelöscht 🙈 Also schnell ins Backup geschaut und … naja das war leider korrupt 😱 Kein Backup kein Mitleid, die Mails waren weg. Daher hab ich mal wieder von Vorne begonnen und mein Backup System neuaufgesetzt. Diesmal mit Borgmatic und der vorhanden Hetzner Storagebox. Hetzner Storagebox Die Storagebox BX1 von Hetzner mit 1TB Speicherplatz reicht für mich für 3,81€ im Monat vollkommen aus und ist preislich top: https://www....

I recently started to add some security features to my asterisk server. One was adding a fail2ban jail. Because I have asterisk running inside of docker, I mounted my log folder and changed fail2ban (installed on my docker host itself) to use the message file (in my case: /opt/asterisk/log/messages) . Start by editing /etc/fail2ban/jail.d/asterisk.conf: [asterisk] enabled = true filter = asterisk action = %(banaction)s[name=%(__name__)s-tcp, port="%(port)s", protocol="tcp", chain="%(chain)s", actname=%(banaction)s-tcp] %(banaction)s[name=%(__name__)s-udp, port="%(port)s", protocol="udp", chain="%(chain)s", actname=%(banaction)s-udp] banaction = iptables-multiport logpath = /opt/asterisk/log/messages maxretry = 5 findtime = 3h bantime = 1d Fail2ban needs a specific timestamp format and to prevent asterisk from creating GBs of logs I changed it to only log notice and error messages in the /etc/asterisk/logger....
