Hello! It's again about my project :(
http://cboard.cprogramming.com/showt...threadid=44636
Now what I need to know that which C/C++ functions are restricted for the server ???
I mean if someone send any C/C++ code via submit-o-matic or email.....how can I check that is he writting some thing dangerous for the server???
Can you tell me the function or Macro names and the way to save the server ???
Can you tell me how to protect server from :
http://www.cs.cf.ac.uk/Dave/C/node20...00000000000000
These types of codes ???
Why not just make sure the program runs as a user with an access level that is too low to do anything harmful?
As this is a contest system he/she must have access with the header files........but I have to restrict that he can't do any herm to the server (with functions or Macros) :( But I am not sure if I restrict the clients user level access then can he do his normal programming?Quote:

Or is there any other way by editing the header files......
Where can I get the list of dangerous functions ???
What I mean is, create a user account that only has access to the directory in which the program resides, etc. You should be able to use security permissions to block dangerous code -- the OS simply would forbid the dangerous activity.
Like Cat said, use an account system, where upon installation (or first use) you let the admin choose a master password, that is all powerful, and also let them choose restricted account password(s) for Joe User.
Oh! My submit page is like this :

Do you say that I'll save all the submitted code on a folder (Linux) and restric the user access levels.........and then he/she won't be able to access systems with his/her C/C++ codes?
