Cloud Storage is a flexible, scalable, and durable storage option for your virtual machine instances. You can read and write files to Cloud Storage buckets from almost anywhere, so you can use. I enabled ssh from the network section in the control panel and set the ssh password. My WD control panel is accessible from the IP 192.168.0.5 But when i login using the username admin or root, it says access denied. SSH access is meant only for debugging purposes Clever Cloud instances are to be seen as read-only resources. Any change made on an instance will not be persisted.You can use SSH access for quick tests, but if you want to persist changes, you need to commit them in your repository. Full Linux filesystem semantics: maintain users/groups, permissions, etc. Rsync: synchronise files and incremental updates directly into cloud storage. Sshfs: mount remote drives over SSH for simple local use. WebDAV: mount remote drives over HTTPS for simple local use. HTTP: serve files such as static web pages or downloads.

You can integrate rsync.net with your existing Linux/UNIX/OSX systems in minutes - possibly with no software installation required. You can pipeline output to us, run remote commands over SSH and manipulate your data with common unix primitives.

Spend enough time in an IT environment and you will likely come across the term SSH keys. If you've already come across this IT term, then you might find yourself wondering, what are SSH keys? SSH (Secure Shell) keys are an access credential that is used in the SSH protocol.

Read the rest of this post to learn more about what are SSH keys or consider watching webinar below to find out more about the SSH protocol and the basics of SSH authentication.

Before this post delves into an explanation on what are SSH keys, let's take a quick look at the SSH protocol.

The SSH Protocol

The first version of the SSH protocol was developed in the summer of 1995 by Tatu Ylonen. Tatu was a researcher at the University of Helsinki when a sniffing attack was discovered on the university network. A sniffing attack intercepts and logs the traffic that takes place on a network, and can provide attackers with usernames and passwords which can then be used to gain access to critical IT assets. Thousands of credentials were impacted, including those belonging to community partnerships. This sniffing attack motivated Tatu to figure out how to make networks more secure, and this ultimately led to the creation of the SSH protocol (SSH.com).

Today, the SSH protocol is widely used to login remotely from one system into another, and its strong encryption makes it ideal to carry out tasks such as issuing remote commands and remotely managing network infrastructure and other vital system components. To use the SSH protocol, a couple pieces of software need to be installed. The remote systems need to have a piece of software called an SSH daemon, and the system used to issue commands and manage the remote servers needs to have a piece of software called the SSH client. These pieces of software are necessary to create a proper communication channel using the SSH protocol (DigitalOcean).

Essentially, SSH keys are an authentication method used to gain access to this encrypted connection between systems.

What are SSH keys?

SSH keys come in many sizes, but a popular choice is RSA 2048-bit encryption, which is comparative to a 617 digit long password. On Windows systems, it is possible to generate your own SSH key pair by downloading and using an SSH client like PuTTY. On Mac® and Linux® systems, it is possible to generate an SSH key pair using a terminal window. Watch the video below to find out how to generate your own RSA key pair on Mac and Linux.

SSH keys always come in pairs, and each pair is made up of a private key and a public key. Who or what possesses these keys determines the type of SSH key pair. If the private key and the public key remain with the user, this set of SSH keys is referred to as user keys. If the private and public key are on a remote system, then this key pair is referred to as host keys. Another type of SSH key is a session key. When a large amount of data is being transmitted, session keys are used to encrypt this information.

Now let's take a closer look at how a private key and public key work. To keep things simple, we will focus on how user keys work.

How User Keys Work

In a user key set, the private key remains on the system being used to access the remote system and is used to decrypt information that is exchanged in the SSH protocol. Private keys should never be shared with anyone. A public key is used to encrypt information, can be shared, and is used by the user and the remote server. On the server end, the public key is saved in a file that contains a list of authorized public keys. On the user's side, the public SSH key is stored in an SSH key management software or in a file on their computer.

Using SSH Keys

First Steps

Before you can start using SSH keys, first you need to generate your own SSH key pair on the system you would like to use to access a remote system. This article and the video mentioned above are great resources that can guide you through on how to generate an SSH key pair. Once the key pair is generated, the next step is to put the public SSH key on the remote server. Depending on your setup, this can be done by entering a couple commands in the terminal window, using JumpCloud, or by manually placing the public SSH key on the remote server (DigitalOcean).

Behind the Scenes of SSH Key Authentication

After completing the steps mentioned above, use your terminal to enter in your ssh username and the IP address of the remote system in this format: ssh username@my_ip_address. This will initiate a connection to the remote system using the SSH protocol. The protocol and specified username will then tell the remote server which public key to use to authenticate you. Then the remote server will use that public key to encrypt a random challenge message that is sent back to the client. This challenge message is decrypted using the private key on your system. Once the message is decrypted, it is combined with a previously arranged session ID and then sent back to the server. If the message matches with what the server sent out, the client is authenticated, and you will gain access to the remote server. This process proves to the server that you have the corresponding private key to the public key it has on file.

However, the security that this authentication process provides can be undermined when SSH keys are not properly managed.

Managing SSH Keys

It is imperative that proper SSH key management is in place because they often grant access to mission-critical digital assets. Also, companies tend to have a lot of SSH keys. In fact, Fortune 500 companies will often have several millions of these. Despite the difficulty in trying to manually manage millions of SSH keys, having an SSH key management system in place is continuously overlooked. SSH.com did some digging and discovered a company that had 3 million SSH keys 'that granted access to live production servers. Of those, 90% were no longer used. Root access was granted by 10% of the keys, ' (SSH.com). An effective SSH key management system in place would have gone a long way in reducing this concerning security risk.

IT has a couple options to gain control over SSH keys in their environment. One of these includes using an SSH key management tool. However, this means having to manage one more platform in addition to managing an SSO provider, a directory service, and maybe a system management solution. A new solution has emerged that is providing IT with a second option: Directory-as-a-Service®.

Cloud IAM offers SSH Key Management

This cloud-based identity and access management (IAM) solution provides IT with one central place to manage SSH keys. Furthermore, IT can also centralize user authentication to Mac, Linux, and Windows systems, cloud servers, wired and WiFi networks, web-based and on-prem applications, and virtual and on-prem storage. With one central place to manage a user's authentication to all of their resources, it becomes a simple matter of a few clicks to deprovision users from all of their resources, including SSH key access to remote systems.

You need to add a SSH key to your Clever Cloud's account to deploy via Git.SSH keys are used to establish a secure connection between your computer and Clever Cloud. A user can have multiple SSH keys.

How to add your SSH key on Clever Cloud?

Cloud Ssh Client

I don't have any, I want to create an SSH key

1. In your Terminal, enter the following bash line:

   This command creates a new ssh key using the provided email, so that the owner of the key can be identified.

2. When prompted in wich file you want to save the key, just press entrer.If it says that the file already exists, enter n for no. Type ls, constat the presence of the file and jump to Add your SSH key on Clever Cloud.

3. When asked, enter a passphrase:

   Which should give you something like this:

I maybe have SSH keys, I want to check

GitHub account and SSH key on Clever Cloud

If your account is linked to GitHub, a panel with your GitHub SSH keys will appear in the 'SSH Keys' tab.You can add any key already present in your GitHub account by clicking on the import button next to it.

Find your SSH key

Cloud Storage Ssd

You may already have an SSH key and so do not need to generate a new one. To check if you have one, follow these steps:

Linux and Mac

1. Wether you use Mac or Linux, open your Terminal application.
2. Run cd ~/.ssh/ in your Terminal.
3. If the folder exists, run ls and check if a pair of key exists : id_ed25519 and id_ed25519.pub.Using id_rsa and id_rsa.pub is fine too. We are just advocating the use of ed25519.Smaller to copy and way stronger than 2048-bit RSA keys.If you can find them, you do not need to generate a new one, simply go to the following'Add your key on Clever Cloud' part!

Windows

1. If you don't have it, download Git for Windows and install it.
2. Run Git Bash (from the Start Menu or from the Explorer with the contextual menu (right click)).
3. Run cd ~/.ssh/ in your Terminal.
4. If the folder exists, run ls and check if a pair of key exists : id_ed25519 and id_ed25519.pub or id_rsa and id_rsa.pub. We would recommend using ed25519 keys. Smaller to copy and way stronger than 2048-bit RSA keys. If you can find them, you do not need to generate a new one, simply go to the following 'Add your key on Clever Cloud' part!

Specific SSH key for Clever Cloud

If you want to use a specific key for Clever Cloud, you can set it in your SSH config by adding this :

Add your SSH key on Clever Cloud

Public SSH Key

To declare your public SSH Key on Clever Cloud, in the left navigation bar, go in 'Profile' and in the 'SSH Keys' tab.

Add the key by entering a name and the public SSH key. The key is the entire contents of the **id_[ed25519/rsa].pub** file including the id_ed25519/ssh-rsa part and your email.

If you see 'access denied' or 'password:' when you push on Clever Cloud, your SSH Keys may be invalid or not available on Clever Cloud. Please check that you SSH Key is present and valid in your profile.

Private SSH Key

If you want to clone a repository from a private repository, you can add a Private SSH Key to an application by creating a folder clevercloud at the root of your application and creating the file clevercloud/ssh.json with the following content:

Of course you need to provide a valid path to a file that contains a valid key and that you will push on the Clever Cloud git remote.

Check your ssh configuration

To check if your ssh key is correctly configured, you can try to run:

The first time, you may have to type 'yes' to continue.

If you see

This error can occur when your SSH agent has not be configured to use your SSH key.

Most of the time, it is due to the presence of multiple SSH keys generated by 3rd party software, like GitHub for Mac.To fix this you will need to configure your SSH agent.

Configure your SSH agent

You can add those lines into your ~/.ssh/config file. It tells your SSH agent which key to pick for a given hostname.Please update your Clever Cloud SSH key path accordingly.
