DPS5315 USB Interface under Linux

I have a DPS5315 from ELV which I bought as a kit together with the optional USB module. However, I had problems using the USB module under Linux. Although the module is based on a CP2102, for which drivers are already available in the kernel, the module did not create a device file, e.g. /dev/ttyUSB0.

Blazing Fast Block Many IPs With Fail2Ban and IP Sets

I am a big fan of the software Fail2Ban to ban hackers, script-kiddies and spambots from my server. If you don’t know the software, it works like this on a SSH server: Fail2Ban monitors the log file of the SSH server, someone tries to log in and enters the wrong password. If Fail2Ban registers this, it evaluates as “Fail”. If someone creates e.g. 4 Fails in a row, an iptables rule is automatically created which blocks the access of the attacker’s IP to port 22 (SSH) for a certain time (temporary ban).
