Re: Can an update of Raspbian enable SSH ?

I fear I don't understand it, I'm simply wondering if I could have got a malware or attacker that changed these interfaces to enabled or if it's just a glitch caused by rc_gui and the fact that I required sudo users to enter a password.

Re: Can an update of Raspbian enable SSH ?

Yes. rc_gui calls 'sudo' and expects not to be prompted for a password. To update it to make it expect to be prompted for a password in order to resolve the problem. I'm just trying to figure out if the fact that the Raspberry Configuration tool in the Raspbian GUI - is displaying that interfaces o...

Re: Can an update of Raspbian enable SSH ?

Could it be the fact that I required all users to enter a password for sudo ? Yes. rc_gui calls 'sudo' and expects not to be prompted for a password. Ah ! Thanks for that important detail. So if I understand correctly, the rc_gui got "broken" when I changed my sudoers.d file to require all sudo use...

Re: Can an update of Raspbian enable SSH ?

But then it's strange, how come the whole services panel of the Raspberry Configuration tool in the GUI have all services on "enable" when they were all on "disable" a while back. I didn't activate them and I doubt I got hacked since SSH was never activated by me, it's got fail2ban on it, and the fi...

As a side, you should mention 'autoclean' as it will be mentioned to the user while updating at some point.
Is it best to use autoclean or clean if one cleans up after every update because of a small SD card ?

Hi there, sorry for reviving this old post but it seemed more relevant than create a new one since it's in the continuation.

Re: How do you update your Raspbian ?

If I "mistakenly" used "upgrade" instead of "dist-upgrade" to make the first update of my Pi after a fresh install of Raspbian, is that a liability that could cause problems down the line ? Thanks !

Thanks it's pretty interesting !
If I don't use SSH and it's deactivated, no need for Fail2Ban right ? Fail2Ban only focuses on SSH right ?
How can I ensure FTP is also disabled, I can't check it's status with raspi-config.

Re: Configured UFW but still can't browse internet or apt-ge

Does the default Chromium on Raspbian uses ports 80 for HTTP and 443 for HTTPS or different ports ? I still don't understand why even with an allow rule on outgoing traffic for ports 80 and 443, I can't browse the net.
