I try to practice to use ssh keygen to generate public key and private key
And then I type cd .ssh
And it said there is no directory.
Then I found that I do it wrong. I use superuser to generate the key
so it create the directory '/root/.ssh/'
Please help me to delete the .ssh directory in the root
Thank you.
You need to log in as the superuser and delete the folder, or just use the sudo command.
sudo su
rm -rf /root/.ssh
or
sudo rm -rf /root/.ssh
Unless you cannot log into your superaccount, then thats a different story.

I want to create an own git server. I started with a root user and here is the following I did:
mkdir /srv/git/project.git
useradd -r -d /srv/git git
passwd git
Now I have a new user git (can log in via su git from my root account).
I want to login via git#mywebsite.com without the use of a password. Right now, it will ask for a password every time.
For root, I have my SSH public key in .ssh/authorized_keys. The key should also work for git. Do I have to add another authorized_keys file for this git user? With my useradd command, I do not create a home directory where I could add it, so where should it go?
Thank you all for your help!
Run sudo tail -f /var/log/auth.log and attempt to login once more from a different console. You will see now the lag that should tell you why exactly the login was denied.
In my case there were wrong permissions for the home folder.
You did create a home directory, it just isn't sitting under /home.
/srv/git
Under that directory create a .ssh directory, fix the permissions:
mkdir /srv/git/.ssh
chmod 0700 /srv/git/.ssh
Create a new authorized_keys file with the public key in it, fix the permissions:
vim /srv/git/.ssh/authorized_keys # or method of your choice
chmod 0600 /srv/git/.ssh/authorized_keys
I am new to linux. I have a build.sh file which consists of a lot of mkdir commands and some rm commands. But as I have installed this new in my VB, each time I run the .sh file, it says "Permission Denied for creating directory" and fails.
So is there any way that I grant directory privileges to all users.
Can anyone help me with this
Add "sudo" in the beginning of the directory creation command i.e
sudo mkdir dir_name
The issue might be with the directory in which the mkdir command is being run.
Use the command ll or ls -l to check the directory permissions.
If your directory doesn't have write privilege for the current user, you can run
chmod -R u+w /path/to/directory
This might require you to use sudo if permission is denied.
If you want to enable it for all users, run
chmod -R ugo+w /path/to/directory
Alternatively, a quick fix would be to run the build.sh file as root
sudo /path/to/build.sh
However, this approach is not advised unless you always run it as root
I am new to linux and I am trying to clone a project into a folder that am currently in contained in opt/lampp/htdocs using the command git clone git#gitlab.com:whatever . but i am getting a permission denied error. What can i do to resolve this issue
update httpd.conf
sudo gedit /opt/lampp/etc/httpd.conf
Find
User nobody
Group nogroup
Replace nobody with your username
Change the ownership of htdocs
sudo chown -R username:username /opt/lampp/htdocs
Change the file permissions of htdocs folder
sudo chmod -R 775 /opt/lampp/htdocs/
Restart your machine
Clear your browser cache
You can also give the folder full permissions like this:
sudo chmod -R 777 /opt/lampp/htdocs/
or sudo chown -R $USER:$USER /opt/lampp/htdocs
I already have my username correctly wrote in user in the httpd.conf file, and still had the same problem. Finally, I found the solution changing the port number:
In the same file look for Local:8888 and change 8888 to 80
try to give full permission to your htdocs folder
sudo chmod 777 opt/lampp/htdocs
Then it will ask for password enter and go ahead. learn More Here :)
Permission denied is exactly what it says. You do not have permission to write to this folder. You can either git clone the repo as a root using sudo git clone (...) or change permissions to this folder. sudo chmod a+w <path> and then git clone it normally. You can also clone the repository to some other folder to which you already have permissions to write to.
I have an id_rsa and id_rsa.pub on my computer also tied into my BitBucket account.
As I understand I can use this public key anywhere I please (as long as my private matches).
The Problem: I cannot figure out how to get any server to accept the public key, do you see what I've done wrong?
$ cat id_rsa.pub >> authorized_keys
$ service ssh restart (I suppose this isn't needed)
$ git pull origin master
$ Permission denied(publickey)
What am I doing wrong? I've been stuck for days.
If you copied your root's authorized_keys you may have to do more than you are used to:
chmod 700 .ssh
sudo chmod 640 .ssh/authorized_keys
sudo chown $USER .ssh
sudo chown $USER .ssh/authorized_keys
Where $USER is your linux username.
Make sure the permissions on ~/.ssh are 700 i.e. only accessible by the owner, and the permissions on the public and private key files are not writable except by the owner.
Make sure the key files are in ~/.ssh !
Make sure the key is being used (try ssh'ing to the right user # the bitbucket server using ssh -v)
You need to copy the content of id_rsa.pub to the bitbucket avcount its in the settings page

Someone please advise how to set the directory to chown root:root and chmod 0600, so that everything in it was created or copy the same settings as configured directory? thank you
Your question is not that clear ... but I think that perhaps what you're looking for is recursive application to apply chown and chmod settings to all files in the directory. This can be done (in both cases) using the -R flag, for example:
chown -R root:root mydir/*
I think you are looking for chmod -R 0600 * and chown -R root:root *, but your question is not entirely clear.
I think you are looking for the -R (recursive) flag - you can use
chown -R root:root /your/directory/full/path
and
chmod -R 0600 /your/directory/full/path
If instead you're copying an existing directory and want to retain permissions you can use
cp -a /current/path /new/path
and the -a flag will keep ownership and permissions the same
I think I understand your question now: you're trying to set the default permissions and ownership for new files in the directory.
For ownership, if you add yourself to the group that owns the directory (root in this case), then new files you create will be owned by that group.
For permissions, you can set default permissions for new files using umask:
umask 077 # grant only user r/w permissions
or using setfacl: see this answer for more information.
