For the github configuration, I have completed the steps of
1.) creating new SSH keys
2.) entering my id_rsa.pub key and thus adding the key
But during the testing stage of testing, after I entered
user$ ssh -T git#github.com
A new window (outside the terminal) opens up asking : Enter your password for "id_rsa". Where can I find this password. FYI, I am using a Mac OS 10.5.8
Even after I entered:
user$ ssh -vT git#github.com
The same new window opens up asking for the "id_rsa" password.
Please help.
While creating your ssh key in step 1), make sure to enter no passphrase for it. Otherwise the setup will be more complicated as you need to use something like ssh-agent to enter the password automatically for you.

I'm using Gitkraken and it keeps forgetting my SSH Key passphrase after every restart of the app. I've tried ssh-add with the Gitkraken CLI/Terminal, but I haven't been able to figure out how to make Gitkraken remember the SSH Key passphrase in between restarts. Can somebody educate me how to do this?
I fixed this by using the local SSH agent on Mac (Ventura OS):
SSG Agent parameter location in Gitkraken
And prior to that I had to load automatically my passphrase in my .zshrc (not sure if it's mandatory to make it work with Gitkraken):
ssh-add --apple-use-keychain ~/.ssh/id_rsa
I need help on how to link my ssh key to ssh agent.
On generating the key which was saved at (mykeys) which i can view, the codes belows where generated in the bash terminal window.
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/user/.ssh/id_rsa): mykeys
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in mykeys
Your public key has been saved in mykeys.pub
The key fingerprint is:
SHA256:/DEK8rKIlb+j1aEVWL3jYG5I0dcuYk4DoKuxrHiGOws user#OshimiriAtata1
The error I keep getting for all my trials is:
No such file or directory
I have followed the instructions I get on various YouTube videos I am watching currently, but cannot figure out what the issue is.
I have tried the following:
ssh-add \~/.ssh/id_1895
ssh-add ..ssh/id_1895`your text`
ssh-add .ssh\\id_1895
ssh-add \~/.ssh/id_rsa`your text`
ssh-add \~/.Henry/.Data-set/.ssh_mykeys
All to no avail.
Please can you help me?
Following "Generating a new SSH key and adding it to the ssh-agent", the command would be:
sh-add C:\path\to\mykeys
And you would need a ~/.ssh/config file with
Host gh
Hostname github.com
User git
IdentityFile C:\path\to\mykeys
Test if this works with: ssh -Tv gh, you should see a welcome message similar to:
Hi *****!
You've successfully authenticated, but GitHub does not provide shell access.
You can use the URL with commands like:
git clone gh:myGitHubUser/myRepository
I ran into this same problem, it kept putting the file on my desktop. I discovered this when I went to search on the bottom left of my Windows machine and typed in the name of my file, in your case "mykeys".
Literally followed the same exact steps you did and it still put it on my desktop.
I am using vscode to connect to a remote host. I use Remote-SSH (ms-vscode-remote.remote-ssh) extension to do so. Every time I want to connect to the remote host, I need to enter the password.
Is there a way to save the ssh password to vscode?
To setup password-less authentication for ssh on Visual Studio Code, perform the following steps.
These examples assume the following (replace with your actual details)
Host: myhost
Local User: localuser
Remote User: remoteuser
Remote User Home Dir: remoteuserhome
SSH Port: 22
I'm using a Mac so Windows will be a bit different but the basics are the same
Tell VS Code and your machine in general how you will be connecting to myhost
Edit:
/Users/<localuser>/.ssh/config
Add:
Host <myhost>
HostName <myhost>
User <remoteuser>
Port 22
PreferredAuthentications publickey
IdentityFile "/Users/<localuser>/.ssh/<myhost>_rsa"
Next generate a public and a private key with something like OpenSSL
ssh-keygen -q -b 2048 -P "" -f /Users/<localuser>/.ssh/keys/<myhost>_rsa -t rsa
This should make two files:
<myhost>_rsa (private key)
<myhost>_rsa.pub (public key)
The private key (<myhost>_rsa) can stay in the local .ssh folder
The public key (<myhost>_rsa.pub) needs to be copied to the server (<myhost>)
I did it with FTP but you can do it however you wish but it needs to end up in a similar directory on the server.
ON THE SERVER
There is a file on the server which has a list of public keys inside it.
<remoteuserhome>/.ssh/authorized_keys
If it exists already, you need to add the contents of <myhost>_rsa.pub to the end of the file.
If it does not exist you can use the <myhost>_rsa.pub and rename it to authorized_keys with permissions of 600.
If everything goes according to plan you should now be able to go into terminal and type
ssh <remoteuser>#<myhost>
and you should be in without a password. The same will now apply in Visual Studio Code.
Let's answer the OP's question first:
How to 'save ssh password'?
Since there is no such thing as "ssh password", the answer to "how to save the remote user password" is:
This is not supported by VSCode.
VSCode proposes to setup an SSH Agent in order to cache the passphrase (in case you are using an encrypted key)
But if the public key was not properly registered to the remote account ~/.ssh/authorized_key, SSH daemon will default to the remote user credentials (username/password).
It is called PasswordAuthentication, often the remote user password.
And caching that password is not supported for SSH sessions.
It is only supported by a Git credential helper, when using HTTPS URLs.
(it defers to the OS underlying credential manager)
But I don't know of a remote user password cache when SSH is used.
As Chagai Friedlander comments, the answer to the original question is therefore:
No, but you can use SSH keys and that is better.
Speaking of SSH keys:
"ssh password": Assuming you are referring to a ssh passphrase, meaning you have created an encrypted private key, then "saving the ssh password" would mean caching that passphrase in order to avoid entering it every time you want to access the remote host.
Check first if you can setup the ssh-agent, in order to cache the passphrase protecting your private key.
See "VSCode: Setting up the SSH Agent"
This assumes you are using an SSH key, as described in "VSCode: Connect to a remote host", and you are not using directly the remote user password.
Using an SSH key means its public key would have been registered to the remote account ~/.ssh/authorized_keys file.
This section is the workaround the OP ended up accepting: registering the public key on the remote user account, and caching the local private key passphrase worked.
For those trying to connect through Vscode Remote SSH Extension steps provided at https://code.visualstudio.com/docs/remote/troubleshooting#_ssh-tips)
For Windows(Host) --> Linux(Remote)
Create an SSH .pub key in your windows ssh-keygen -t rsa -b 4096
Copy the contents of the .pub key (default path C:\Users\username/.ssh/id_rsa.pub)
SSH into Remote machine and append the contents of the pub key in authorized keys echo "pub-key" >> ~/.ssh/authorized_keys
I followed the guide from https://help.github.com/articles/generating-ssh-keys/ to generate a ssh key used to connect to github from my server.
The problem is if I close the shell and login the server again, I have to repeat below steps to reconnect to github, otherwise the accessing will be denied:
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
How can I setup a permanent connection with github?
Since you are logging on to the command-line (presumably using SSH) all applications that you run, including ssh-agent, stop when you log out.
In my opinion your best bet is to have your CentOS machine start ssh-agent for you each time you log in, then manually use ssh-add to add your key. This can be done by modifying your shell's login script. If you are using bash, this file is called ~/.bash_profile. If you are using another shell, refer to its documentation and choose an appropriate file.
Edit one of these files and add eval "$(ssh-agent -s)" at the end.
Now, each time you log in ssh-agent should automatically start, and you can optionally run ssh-add (since you are using a file that ssh-add looks for by default you don't need to pass the file to the command) to add your key, then do Git stuff.
It sounds like you want to automate the adding of the key as well. This isn't something that I would choose to do since I like adding keys to be explicit, but because you don't have a passphrase on your SSH key you should be able to add ssh-add to the same file we modified above (after we start the agent, of course) and have your key added automatically.

I did the following and it worked:-
Step1:- .bash_profile
Step2:- enter image description here
Step3:-source .bash_profile
Step4:- enter image description here
Here is my setup:
Jenkins is running on my linux machine as 'jenkins' user.
I have generated a ssh key-pair as described in Linux - Setup Git, for the 'jenkins' user.
When I sudo su jenkins and try ssh -vT git#github.com, I am always asked my passphrase, but I am always eventually authenicated. (the verbose option shows which key is used, among others).
I could clone my repo from GitHub using jenkins:
Thusly:
jenkins#alpm:~/jobs/test git/workspace$ git pull
Enter passphrase for key '/var/lib/jenkins/.ssh/id*_rsa':
Already up-to-date.
Up to this point I have followed the instructions to the letter. The problem is that the Jenkins job fails with the following error:
status code 128:
stdout:
stderr: Permission denied (publickey).
fatal: The remote end hung up unexpectedly
This is same error as I get when I typo the passphrase (but of course, Jenkins does not ask me for the passphrase). The following pages:
GitHub - SSH Issues
Using SSH Agent Forwarding
indicate to me that ssh-agent could help remember the passphrase, which it does when I am using my own user, but not the jenkins id. Note that while running as my normal user yields:
echo "$SSH_AUTH_SOCK"
/tmp/keyring-nQlwf9/ssh
While running the same command as my 'jenkins' yields nothing (not even permission denied)
My understanding of the problem is that the passphrase is not remembered.
Do you have any idea?
Shall I start a ssh-agent or key ring manager for the jenkins user? How?
Or is ssh forwarding suitable when forwarding to the same machine?
Any brighter idea?
ps: I never sudo gitted, I always used jenkins or my user account (as mentioned in this SO post - Ubuntu/GitHub SSH Key Issue)
Since nobody wrote the answer from the comments for several months, I will quickly do so.
There are 2 possible problems/solutions:
id_rsa created with wrong user
Create id_rsa as the jenkins user (see hudson cannot fetch from git repository)
Leave passphrase empty
To summarise what must be done on the Jenkins server:
# 1. Create the folder containing the SSH keys if necessary
if [ ! -e ~jenkins/.ssh ]; then mkdir ~jenkins/.ssh; fi
cd ~jenkins/.ssh/
# 2. Create the SSH pair of keys
# The comment will help to identify the SSH key on target systems
ssh-keygen -C "jenkins" -f ~jenkins/.ssh/id_rsa -P ""
# 3. Assign the proper access rights
chown -R jenkins ~jenkins/.ssh/
chmod 700 ~jenkins/.ssh
chmod 600 ~jenkins/.ssh/*
Remember:
Please keep the default "id_rsa" name when generating the keys, as other such as "id_rsa_jenkins" won't work, even if correctly set up.
Do not use a passphrase for your key
Check that the public key (id_rsa.pub) has been uploaded on the git server (GitHub, Bitbucket, etc). Once done, test your SSH key by running: ssh -vvv git#github.com (change address according to your git server)
I got around this problem by simply leaving the passphrase empty when creating the keys.
I would add that if you created the keys by hand, they might still be owned by you and not readable by jenkins, try:
sudo chown jenkins -R /var/lib/jenkins/.ssh/*
To check are the following:
if the right public key (id_rsa.pub) is uploaded to the git-server.
jenkins user will access to github -> to CHECK if the right private key (id_rsa) is copied to /var/lib/jenkins/.ssh/
if the known_hosts file is created inside ~/.ssh folder. Try ssh -vvv git#github.com to see debug logs. If thing goes well, github.com will be added to known_hosts.
if the permission of id_rsa is set to 755 (chmod 755 id_rsa)
After all checks -> try ssh -vvv git#github.com
Dont try to do config in jenkins until ssh works!
If you are running jenkins as a service in windows, you need to verify the user running the service. If you created the keys using the user "MACHINENAME\user", change the service so the user running it can match
For Mac users, the issue can be solved by removing the existing keys and creating new Private and Public Keys by following these steps:
1.Remove all Public and Private keys located at /Users/Username/.ssh
2.Remove all the credentials saved under the Credentials tab in Jenkins.
3.Remove the existing Public SSH keys defined in the Github Repository Settings.
4.Create new SSH keys (private and public: id_rsa and id_rsa.pub) by following the steps from https://confluence.atlassian.com/bitbucketserver/creating-ssh-keys-776639788.html#CreatingSSHkeys-CreatinganSSHkeyonLinux&MacOSX
5.Set the newly created public SSH key (id_rsa.pub) in Github or an equivalent Repository Settings.
6.In Jenkins,create new credentials by adding the private SSH key(id_rsa) for your Github username.
7.The Error should be removed now.
keys need to generated from jenkins user.
sudo su jenkins
ssh-keygen
once the key is generated, it should be added as ssh key in bitbucket or github.
