I think the op meant you to use chmod and chown to make the exe setguid I will admit that i've not tried this yet. You make have to provide a small shell script wrapper like so.
#!/bin/bash mono path/to/myprog.exe And then do : $ su - $ chown root myscript $ chmod 700 myscript $ chmod u+s myscript $ exit $ ./myscript -- Sent from my Android phone with K-9 Mail.

I tried to create a small application for testing purposes: <code> using System; using System.IO; using System.Runtime.InteropServices; namespace AdminTest { class AdminTest { public static void Main(string[] args) { Console.WriteLine("Current uid/gid: {0}/{1}", getuid(), getgid()); int resultGid = setgid(0); if(resultGid != 0) Console.WriteLine("Errorcode gid: {0}", Marshal.GetLastWin32Error()); int resultUid = setuid(0); if(resultUid != 0) Console.WriteLine("Errorcode uid: {0}", Marshal.GetLastWin32Error()); Console.WriteLine("Aquire root rights {0}", result); } [DllImport ("libc", SetLastError=true)] public static extern int setgid(int gid); [DllImport ("libc", SetLastError=true)] public static extern int getgid(); [DllImport ("libc", SetLastError=true)] public static extern int setuid(int uid); [DllImport ("libc", SetLastError=true)] public static extern int getuid(); } } </code> After compiling and executing I only get: <code> Current uid/gid: 501/20 Errorcode gid: 1 Errorcode uid: 1 Aquire root rights -1/-1 Current uid/gid: 501/20 </code> I tried the same exe under (sudo su): <code> Current uid/gid: 0/0 Aquire root rights 0/0 Current uid/gid: 0/0 </code> I expected some kind of "Mono wants to access administrator privileges"-Popup of the keychain but nothing happened. I would still need to do some chown and chmod stuff (chown root.root, chmod +s) to allow the application accessing root privileges and therefore I still have the same problem. How do all those installers solve this problem?
