scanmem is a debugging utility designed to isolate the address of an arbitrary variable in an executing process. scanmem simply needs to be told the pid of the process and the value of the variable at several different times. After several scans of the process, scanmem isolates the position of the variable and allows you to modify its value.
NetworkTools has 2 components: A protocol analyzer which plays a TCP client or server or pipeline, which sits between a client and server and shows how they communicate. A port scanner can scan a range of IP addresses and ports. See screenshots.
