See discussions here: > > https://bugzilla.redhat.com/show_bug.cgi?id=89216 > https://bugzilla.redhat.com/show_bug.cgi?id=136289 Note that saying that it has been like this for ever is not a valid point. We have had incident reports here on the university network where a novice end user both staff and students installed Fedora on their laptop/workstation and to no surprise were instantly exposed to brute force attacks without absolutely no idea about it heck those users did not even know what ssh is in the first place. There is no warning or option to disable sshd in Anaconda and the novice end user receives no notifications about someone trying to connect to ssh so he is absolutely clueless when that happens so even if he knows how to react when that occurs he still has no idea if/when it's happening. I think this only applies to install of the default dvd not the live cd/usb images And this is a valid concern.
