Github Help Generate Ssh Key
When you clone your github repository you can select http and ssh url for github project. You can clone with HTTPS, SSH or Subversion. I think you should select ssh to work with ssh authentication. Check your cloned git project's config. There is a remore url that you can change to ssh url. This page describes how to create SSH keys. SSH keys can be used to establish a secure connection with Bitbucket Server for: when you are performing Git operations from your local machine; when another system or process needs access to repositories in Bitbucket Server (for example your build server).

Ssh Key Github
| Full Instructions here: https://forum.synology.com/enu/viewtopic.php?t=126166 |
| System: Synology DS1815+ running DSM 6 |
| Log into Synology web UI as an administrator user |
| Enable “User Home” |
| Control Panel / User / Advanced, scroll down to “User Home” |
| Check “Enable user home service”, select an appropriate Location (i.e. volume1) |
| Click “Apply” |
| Create user account(s) that should access Synology via SSH (or via rsync over SSH), using the Synology web UI as normal. |
| Enable SSH for the Synology server |
| Control Panel / Terminal & SNMP |
| Check “Enable SSH Service” |
| Click “Apply” |
| Log into Synology as admin user via SSH |
| Launch SSH application (putty, or other) |
| Specify IP address (or host name) of Synology |
| Provide admin username and password |
| Fix the permissions on all home directories |
| cd /volume1/homes |
| to change to the directory containing home directories |
| “volume1” was selected when you enabled “User Home” above |
| ls -al |
| to show all home directories |
| The important thing is that home directories for SSH users MUST be writable ONLY by the user. The web UI creates these wrong. For each home directory, change permissions: |
| sudo chmod 755 /volume1/homes/someuser |
| Changes permission to full (read/write/execute) for the user, but to read/execute only for the group and for everyone else |
| For each user that you want to grant SSH access to, edit their passwd entry to give them sh access |
| NOTE that the changes may here may be reverted upon reboot of the Synology. See https://andidittrich.de/2016/03/howto-r .. users.html |
| sudo vi /etc/passwd |
| move down to the user you want to modify, move to the end of the line |
| press “I” to go into insert mode |
| backspace over “/sbin/nologin” and replace with “/bin/sh” |
| when done editing, press “ESC”, then “qw” (quit, write file) |
| if you make a mistake and want to quit without saving, press “ESC”, then “q!” (quit, without saving changes) |
| For each user that you want to grant SSH access to, generate SSH keys |
| You could do this while logged in as admin, but you would need to manually mess with changing ownership and permissions of files you create here. It is better / easier to log in as each individual user to perform the following. |
| Re-launch your SSH application (putty, or other) to open a new session with the Synology |
| Log in as the user you want to set up |
| Create folder for SSH keys for the user and set permissions |
| mkdir ~/.ssh |
| creates a hidden .ssh directory to hold the keys |
| chmod 0700 ~/.ssh |
| sets proper permissions for the folder (full rights to user, no rights to anyone else) |
| touch ~/.ssh/authorized_keys |
| Creates a new empty file named authorized_keys. This will hold the public keys of remote users that are allowed to log in here as this Synology user. |
| chmod 0644 ~/.ssh/authorized_keys |
| Set permissions of the new authorized keys file. (read/write to current user, read-only to everyone else) |
| ssh-keygen |
| Generate public and private keys |
| Press “enter” to accept default file location (should be user’s .ssh folder) |
| Press “enter” twice to indicate NOT to create passphrase. (The passphrase would prevent the login from working when used by rsync.) |
| Will add files id_rsa (private key) and id_rsa.pub (public key) |
| These should automatically be created with the correct permission (read/write by user only, i.e. chmod 600). You shouldn’t need to make any changes. |
| Configure the Synology’s SSH service to allow login by key |
| Go to an SSH session (Either an administrator or an SSH user. You may still have one open.) |
| cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak |
| makes a backup copy of the config file, just in case something goes wrong |
| sudo vi /etc/ssh/sshd_config |
| Uncomment line that says: #PubkeyAuthentication yes |
| Uncomment the line that says: #AuthorizedKeyFiles .ssh/authorized_keys |
| Make sure that line is uncommented that says: ChallengeResponseAuthentication no |
| Optionally, if you want to disable password-based logins, add a line: PasswordAuthentication no |
| Save the file and exit the editor |
| Restart the Synology’s SSH service |
| sudo synoservicectl --restart sshd |
| Or use web admin: Control Panel / Terminal & SNMP; uncheck “Enable SSH service”; apply; check “Enable SSH service”; apply |
| If there is an error in the config file, the service may not restart. If this is the case: |
| Enable telnet (Control Panel / Terminal & SNMP / Terminal) |
| Log in to the Synology as an admin user via a Telnet application (telnet, putty, or other) |
| Copy the config backup file you made above, and restart the sshd service again. |
| sudo cp /etc/ssh/sshd_config.bak /etc/ssh/sshd_config |
| sudo synoservicectl --restart sshd |
| Create SSH keys for the remote user that will be logging into the Synology (i.e. the FreeNAS user) |
| On the remote / client system that will be logging into the Synology, log in as the user that will need to log into the Synology. |
| ssh-keygen |
| Generate keys as you did on the Synology in #8 above |
| The other steps (creating an .ssh folder, setting permissions, etc.) are already done by FreeNAS. When done though, the permissions on the remote folders and files should match what you did on the Synology. |
| The authorized_keys file not needed at this time (it is only needed on the server-side of the SSH login), but it doesn’t hurt to create the file for future use. |
| Copy the remote/client’s public key to the Synology. This can be done in a number of different ways, but the main thing you need to do is to get the contents of the remote user’s id_rsa.pub file into the Synology user’s authorized_keys file. The entire contents must be on a single line of the authorized_keys file. One way to do this: |
| ssh-copy-id -i ~/.ssh/id_rsa.pub synologyIP |
| Replace “synologyIP” with the actual IP address of your Synology |
| You will be prompted for the Synology username and password that you want the current local user to log into the Synology as. |
| From the remote/client SSH session, try logging into the Synology using the new key: |
| ssh synologyUser@synologyIP |
| Replace synologyUser with the actual Synology user you want to log in as, and replace synologyIP with the actual Synology IP address. |
| You should NOT be prompted for a password. |
| If the Synology username is the same as the remote/client username, synologyUser@ is optional. |
