Hi, Short Version Yesterday, while I was trying to fix a time machine backup problem when I screwed up. (this sums it up, doesn't it ?) More seriously, I executed chflags -R nouchg and chmod -RN on my / directory. Fortunately, I saw at some point (after 8 min.) that it was the wrong command. I canceled it. Repairing permissions did not find anything wrong (so no repairs done). My system is working fine, but now, I can no longer ssh my website. I investigated a potential permission problem on my .ssh folder and files without managing to fix this most unfortunate issue. Please, can anyone tell me what are the permissions of your .ssh file and folders, and of your ssh command ? To do this, please open the terminal and execute the following command: ls -le /Users/$(whoami)/.ssh and please, paste the result in this topic. Then, execute ls -le $(which ssh) and please, paste the result in this topic. Thank you very much for your help. Detailed version I did run the following commands: sudo su- chflags -R nouchg chmod -RN on the directory "/ /Users/me/......". Some of you may have noticed the extra "/" followed by a space. Which means that the command was first executed on / and then on the folder I requested.
