Drop specified IP n seconds remotely, auto-undrop it when timeout.
It's a IDS-receiver and written in C. Sometimes I want to drop remote IP xx seconds, and Undrop it when timeout; Sometimes my sniffer-server find a hack-action and I want to tell another server/server-group "Drop xxx.xxx.xxx.xxx IP xx seconds". So I written this program -- dynipdrop("dynipdrop" daemon and "ipdrop_local" to send a drop-msg from localhost, and "ipdrop_udp" to send a drop-msg to another server(installed the dynipdrop daemon). And I think: "Maybe I can make a client to drop the ssh-scan, like DenyHost(http://denyhost.sf.net)", so I write the "sshdprotector". dynipdrop run on linux and need iptables, I use "portsentry(http://sourceforge.net/projects/sentrytools/" + "sshdprotect" + "dynipdrop" to protect my servers, and hope this software make some help to you.
IoT Device, Gateway, Server platform
Bi-directional Wireless Sensor Line Protocol(Bi-WSLP) is a sensor network communication protocol based on a line topology, which is common in outdoor monitoring cases for IoT(Internet of Things). Bi-WSLP runs fast and provides a response rapidly, yet it takes a small code size occupies small memory. Bi-WSLP can be easily ported to various hardware platforms because it is coded in C, which is the most popular programming language for embedded systems. In addition, Bi-WSLP allows transmission of large-size data such as still images as well as common sensor data such as temperature and humidity. Bi-WSLP can be modified to conform to the IEEE 802.15.4 standard. Bi-WSLP supports bidirectional data transmission, so it allows a user not only to control the operation of sensor nodes immediately, but also to receive responses to the user almost in real-time.
