ssh - a treat for your GitHub

ssh commands

ssh creation

1. ssh key should be in /home/.ssh folder
2. to generate ssh key-

ssh-keygen

• the command will ask you the name of the file, you can enter it. Let say, you named it "secure-shell" and follow the next instructions:

1. It will create two files in the same folder one is a public key file with extension .pub file and the other one is a private file. In our case, it will create "secure-shell.pub" and "secure-shell"

2. It needs your attention,

secure-shell - never share this with anybody
secure-shell.pub -to be share with a remote server that you want to excess

• When you have multiple private keys then you have to add a specific key to your main identity.

eval $(ssh-agent)
ssh-add ~/.ssh/secure-shell

difference ssh-add /.ssh/secure-shell V/S ssh -i /.ssh/secure-shell ?

add will set the identity of your system for a current pointed ssh key for every commit, whether -i will set temp identity pass key(ssh key) in case you have different ssh keys added to the different remote workspaces.

GitHub access

1. write the following command to view the ssh-key (we will use secure-shell i.e. our key name). Please access the directory where your ssh key present.> cat .ssh/secure-shell.pub
2. The above command lists a key, copy it!!
3. Goto git account, setting > SSH and GPG keys > New ssh key and paste here
4. that it
5. Remember, you need to generate two ssh keys to access two different git accounts. Each git account will require a unique ssh key to be added. It is a good practice.

Remote access

1. On your local machine > cat .ssh/secure-shell.pub
2. The above command lists a key, copy it!!
3. go to the remote machine and write following command > sudo vi .ssh/authorized_key
4. Press i button to write
5. paste your key here and press ESC button
6. Write :wq

NOTE - how to know which ssh is currently added

ssh-add -l

It's pretty simple, right !!
