UNIX for Dummies Questions & Answers

After much reflecting I decided that I don't want to have a remote managemente in my computer and I digited in Terminal from the Administrator Account:
chmod ug-s /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent
But the answer is: NOT PERMITTED Why? Is it not strange?! terminal should allow the administrator to disable setuid or setgid, or not?...

Please post:

Code:

# Which user am I?
id
# Permissions of the file (or non-file?)
ls -lad  /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent
# Permissions of the parent directory
ls -lad  /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS

To my mind if you don't want to run a service, don't start it on your computer.

In earlier posts we learnt that the O/P has been reading about "hardening" on an unspecified computer running MACOS X from a US Government website.

I was that one! My mouse moves by itself, I have to do something. Then Corona told me I have to be careful and understand what I am doing. So I found the right file. I didn't put that service in my computer, it is a Mac Book Pro you buy it so. thank you for your answer!

How can I tell thank you? Is it enough to say 'thank you' or do you need a procedure?

Just click the "Thanks" icon at the bottom of the post if wish to thank a poster for a post. It is not necessary to write an additional post.
You can also use the "Thanks" icon to acknowledge that you have read a post because this lets the poster know that you saw the post.

I believe that you are the first poster on this site to attend to security on the Mac Book Pro. Imho It is an excellent computer with a stable unix O/S but a tendency to overheat and burn your data due to styling giving way to cooling.
Don't forget to buy a backup device (or the online service from Apple) and make sure that you have a rock solid backup.

Hmm If you are messing with system permissions a decent backup is so important.

@Vera
We are enjoying your posts and their analytical content. Imho You have a great future in unix Systems Administration.

You are definitely right! I will back up my files. I just found out what a wonderful world is hiding behind the daily, normal use of a computer. I love these commands on Terminal. I have not jet begun with the security program, at first I will buy a hard drive and make the back up. I will tell you about the progress, how my Mac will react to all these changes and so on. After I disabled Bonjour through sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist I noticed an unusual overheating and some strange movement in the 'console'. Therefore I am planing to re-enable it and instead to disable Disable Setuid and Setgid.
