Introduction 简介

pstrap(Port Scanner Trap) listens on specific ports (trap ports, e.g., pretend to be a SSH server on tcp port 22) and deny all access from those IPs who connect these ports. It is a simple way to prevent port scanning. Only work with iptables.

pstrap(Port Scanner Trap)侦听特定的端口（陷阱端口，例如监听22 tcp 端口来伪装成SSH服务），并且会阻止连接这些端口的IP到本机的所有连接。这是一个阻止端口扫描的简单方法。 需要和iptables配合使用。

Configuration 配置

# /etc/pstrap/pstrap.ini
[DEFAULT]
trap_ports = 22,3389    # trap ports
db_file = /etc/pstrap/pstrapped.ini # file stores trapped IPs
log_file = /var/log/pstrap.log  # log file
trapped_duration = 10080    # minutes that a IP is trapped, after which the rule is deleted. set to zero to disable this function.
