How to revoke authorized remote access to my computer system?


I gave a friend remote access to my computer for times when my computer was not working correctly and then they could jump on my computer, from their own computer miles away, and see what was wrong. I imagine that there is a file in my file system that allows this.

If I wanted to revoke that permission to come on my computer, with no permission needed, as is the case now, how would I do that?

The software used to create this was typical of the kind a computer company would use when you call them with a problem about your computer; you tell them a code, created by the software, that they need to gain access, etc, and they remotely connect.

Thanks.

Hi, On my system and others that program is called Teamviewer.

https://www.teamviewer.com/en-us/trust-center/security/

scroll down to "TeamViewer Ports"

Personally I would just uninstall the program, but you can switch off teamviewer service...

It may be different on your system (?) but on mine it is as easy as typing (as root)...
Code:
service teamviewer stop
I hope this helps you.

ps, to make teamviewer not start again at boot time, try...
[code]
chkconfig 12345 teamviewer off
[\code]

And we are left to guess which of the historically huge number of remote access programs are involved in your case?
I can think of 1000 ways, depending upon exactly WHAT you did to GRANT access. You really need to help us narrow this down by providing better information.

Thanks. I'm using ubuntu 18.04 and I think teamviewer is correct (2 years ago). But "teamviewer.service" not found. I typed "sudo service teamviewer stop". Is there a particular directory where this file, if it exists, might be found? With the 'code' command - doesn't seem like that would work in a shell - must go into a file.

ubuntu 18.04 was not available 2 years ago. Did you reinstall your host? Did you really use teamviewer (or something else)?

hi, I haven't used ubuntu. So, I'm googling for tips...

Will your system use
Code:
systemctl enable teamviewer
type "systemctl --help" to find out how to configure it.

Remmina is another popular rdp. remote desktop program

location is... /etc/systemd/system/

OP seems to be wanting the opposite:
Code:
systemctl stop teamviewer
systemctl disable teamviewer
systemctl mask teamviewer
should prevent Teamviewer from functioning.
Code:
sudo apt purge teamviewer
should also work, if indeed it was Teamviewer that enabled the access.
