Write a network scanner with SMB brute force

I want an app named "Scanner Plus", which will do 3 things on the wifi network that the cellphone is connected to: 1. Ping all the subnet range 2. For all responding computer, perform a well known ports scan according to the list here: [login to view URL] 3. If the computer has an open SMB port, try to login without credentials. If it doesn't work, read a files called [login to view URL] and [login to view URL] which will contains usernames and passwords each in a new line. Try each user with all passwords until you it's OK or the list is over. 4. If the app managed to login to the SMB share, do a full directory listing with a depth of 3 (no more than 3 subfolders for each folder found on the root share) 5. Report all findings to pastebin and store the link to pastebin in the app according to GPS location and wifi SSID (access point name) Note that the app should give a clear indication what it's doing, at least which server it's scanning at the moment. And also a general progress bar to show how it progresses through the stages. Source code should have comments at least for each function! SMB related functions should be documented for each line with comments. Administrative: Each step should be performed within 3-4 days, 50% payment will be done in at the end of stage 3 (provided that the app indeed managed to login to an open share and a protected share with the given credentials) and rest at the end of the project. If you fail to deliver each stage on time without approval, you will not be eligble for payment, this is very important to me. YOU MUST UPLOAD THE SOURCE CODE FOR EACH STEP WHEN IT'S COMPLETE, otherwise it will not be accepted. Open source libraries only please, I don't want to pay for external libraries.
