Linux@lemmy.mlbySandal6823@sh.itjust.works11 monthsWhy disable ssh login with root on a server if I only log in with keys, not password? On a server I have a public key auth only for root account. Is there any point of logging in with a different account? 7899104

SavvyWolf@pawb.socialEnglish11 monthsI don’t think that actually works; the attacker could just remove .bashrc and create a new file with the same name. 050%1
2ndSkin@sh.itjust.works11 monthsIf the .bashrc is immutable, the attacker can’t remove it. That’s how it works. 475%6
SavvyWolf@pawb.socialEnglish11 monthsThe home directory would need to be immutable, not bashrc. 050%2
2ndSkin@sh.itjust.works11 months? It’s .bashrc, not bashrc, and .bashrc is in the home directory. If .bashrc is immutable, it can’t be removed from home. 4
SavvyWolf@pawb.socialEnglish11 monthsIt’s the directory that needs to be writable to delete files, not the file itself. Although the immutable bit (if that’s what you’re talking about - I thought you meant unsetting the write bit) might change that, I’m not sure. 1
WheelchairArtist@lemmy.worldBanned11 monthsyou’re right. that’s something i wanted to look into. guess setfacl would do the trick? 167%2

“chattr +i” is what I use to make things immutable
