Python uses the Python-nmap module for port scanners

Port scanning on an online server can be useful to verify your firewall rules and avoid unwanted services. You can also know what services you have opened on your machine, do not have to wait for the clouds to burst out to know, someone hacked into the intranet for several months. Haha, the real thing, the server was passed Zabbix Black in, opened a socket5 process, free access. Anyway, this thing is very useful, in the spirit of dedication, put the code out and learn together.

The function is very simple, scan the server, generate the scan result in HTML format, send the message to the scan result. Format to do a bit of processing, define the port whitelist, normal port display green, abnormal port display red. Kind of an alarm. Full port scanning of the server is a time-consuming thing, with 60,000 + ports per port, and also depending on the network connectivity of the scanning machine to the target machine. Can not be affected by this snail speed, the development of the first version of the single-threaded version, and realized a multi-process version, really cool a lot. The whole person is all right ...

mytools.py This is the definition of a library of functions, the use of a function, the sendemail of the e-mail function, of course, the current scene can be defined in a file, but it is a good habit to split the program by module. Haha, I'm a little pythonic.

nmscan.py implementation of the port scanning program, single-threaded version, the code is a bit long, cautious into

mutinmscan.py port scan of the multi-process version, compared to single-threaded version of the largest one change is the implementation of the Nmscan function, single-threaded to pass a list of servers, inside the function loop the list, read the scan results, generate report messages. The function of version Mutinmscan is to accept an IP address, which uses the pool of the Mutiprocess library and uses its map function to iterate through the list of server IPs. Multi-threading, a section more than five knots strong ...

Scan results: Mosaic block The progress of human civilization, especially in the appreciation of the island action film, but, pro, I can not give our server to you to see, you understand!
