restricted pc shutdown

Both Vista and Windows XP let you take control of preventing a user not to shutdown the machine by editing the group policy. For example if your friend is using your computer and you went somewhere ( and you have still some unsaved document left) and he shutdowns the pc without saving them…you loose a good amount of data. ( Trust me I have lost one whole blog post and project code at same time ). This is what you can doRestrict PC Shutdown* Type gpedit.msc in run dialog box [ WIN KEY + R ]* This will open Group Policy Editor. Now there are two things in it, Computer Configuration and User Configuration* Click on User Configuration > Administrative Templates > Start Menu and Task Bar* Now look for “remove and prevent access to shutdown command”* Double Click and Enable it.* Exit the group policy editor.This setting removes the Shut Down option from the Start menu and disables the Shut Down button on the Windows Security dialog box, which appears when you press CTRL+ALT+DEL. This setting prevents users from using the Windows user interface to shut down the system.Now if you try to shutdown by clicking on start , the shutdown button must have disappeared. Moreover check the task manager and you will find all shutdown,restart and others disabled except switch user.

some tricks

This is a complimation of computer tricks, mainly security and privacy related.

Getting Ip’s:–

To see the ip all computers you are connected to (web servers, people attempting to **** into your computer).Go to dos (start>run>type command) and run the netstat command. Type netstat /? for details.

Type netstat -r at the command prompt to see the ip of all computers you are connected to

In MSN (and other programs) when you are chatting to someone everything you type goes through the MSN servers first (they act as a proxy) so you see their ip rather than who you are chatting to. You can get round this by sending them a file as MSN doesn’t send file through its proxy.When you type the netstat -r (or -a for a different view) the ip’s are under the foreign address table. The ports are seperated by a : . Different programs use different ports, so you can work out which ip’s are from which program.

Connecting to other computers and what ports are:–

Servers send information. Clients retrieve. Simple.Windows comes with a built in program to connect to other computers called telnet.To start Windows telnet Start menu> Run> type Telnet. Click connect> remote systemPorts are doors into computers. Hosts are computer names(ip number or a name that is translated into the ip automatically)Different programs open different ports, but they always open the same ports so other computers know which port to connect to. You can get a port list listing all the different ports, but a basic one is:11 :- Sends info on the computer21 :- FTP (File transfer program)23 :- Telnet (Login to the computers command line)25 :- Smtp (Sends mail)80 :- Http (Web pages

)There are thousands of different programs using different ports. You can get programs called portscanners which check a computer for all ports up to a certain number, looking for ways in. You can portscan a computer looking for ways-in.Anyway, back to telnet.Type www.yahoo.com as the host and port as 80 the click connect.If nothing happens, you’re in. Wow. You are connected to Yahoo’s server.You can now type http commands (you are connected to an http server, so it supports http commands). Ie. on an ftp server you can type open and it will do something. On an http server it will just wonder what the hell you are on about.Type get / http/1.0 then press enter twice to get the file on the server at / (try /index.html) etc.)

Making undeletable, unreadable folders

Tested on Windows 95/98By holding down alt, then typing numbers on the number pad (right of the keyboard) you can create special characters. If you hold down alt, then press 1, then let go, you got the ascii character 1. You try some randomn numbers. This goes all the way up to 255. Open a dos prompt, and type md (alt+1+9+4)someword. md is the dos command to make a directoy, now try and open the directory in Windows, you can’t. To open it, type ren (alt+1+9+4)someword someword (ren is the dos command to rename)

Proxies

Proxies are computers that you connect through, hiding your computer. Most aren’t anonymous, they give away your ip. Some are. Good anonymous proxies: mail.uraltelecom.ru:8080 and 194.247.87.4:8080.Different programs require different ways of using proxies. To do it in internet explorer 5 go to tools, internet options, connections, settings. In the above proxies they are in the format host:port

Password files

If you lock yourself out of Windows stuff, all passwords are stored in files called *.pwl in C:windows.In Unix, passwords are normally stored at etc/passwd. This can be viewed using the cat command (prints a file to screen): cat etc/passwd. Make sure you’re passwords are shadowed (not actually in etc/passwd). Also make sure they aren’t in a file called shadow, especically not in a file called etc/shadow.Unix passwords are encrypted far better than Windows one’s (to be fair, Windows 95 isn’t designed for users), but can still be cracked through a program called jon.
