ssh directory not being created

Question

To generate the  ssh dir I use this command   ssh-keygen   taken from this tutorial  http   ebiquity umbc edu Tutorials Hadoop 05 20- 20Setup 20SSHD html  But the  ssh directory is not created so when I use cd    ssh I get this error    no such file or directory    Is there a step missing   Should the  ssh dir be created when I use the ssh-keygen command

I am assuming that you have enough permissions to create this directory.

To fix your problem, you can either ssh to some other location:

ssh [email protected]

and accept new key - it will create directory ~/.ssh and known_hosts underneath, or simply create it manually using

mkdir ~/.ssh
chmod 700 ~/.ssh

Note that chmod 700 is an important step!

After that, ssh-keygen should work without complaints.

Is there a step missing     Yes  You need to create the directory   mkdir   HOME   ssh   Additionally  SSH requires you to set the permissions so that only you  the owner  can access anything in    ssh     chmod 700    ssh      Should the  ssh dir be generated when I use the ssh-keygen command    No  This command generates an SSH key pair but will fail if it cannot write to the required directory     ssh-keygen Generating public private rsa key pair  Enter file in which to save the key   Users xxx  ssh id rsa    Users tmp does not exist Enter passphrase  empty for no passphrase    Enter same passphrase again   open  Users tmp does not exist failed  No such file or directory  Saving the key failed   Users tmp does not exist    Once you ve created your keys  you should also restrict who can read those key files to just yourself     chmod -R go-wrx    ssh

As a slight improvement over the other answers  you can do the mkdir and chmod as a single operation using mkdir s -m switch     mkdir -m 700   HOME   ssh   Usage  From a Linux system    mkdir --help Usage  mkdir  OPTION     DIRECTORY    Create the DIRECTORY ies   if they do not already exist   Mandatory arguments to long options are mandatory for short options too    -m  --mode MODE   set file mode  as in chmod   not a rwx - umask
