Depending on the SSH port of the Backup account/Storage Box you use, you may need to use a specific format for the public SSH key. The following keys are supported: | SSH Port | Key Format | Algorithms | | --- | --- | --- | | 22 | RFC4716 | RSA, ECDSA | | 23 | Standard OpenSSH Format | RSA, ECDSA, ED25519 | If you want to use the services over both ports, then you must store the public SSH key in both formats (RFC4716 and OpenSSH format) in the `.ssh/authorized_keys` file. Please note that a new line should be at the end of the file. Each sub-account requires its own authorized_keys file in the sub-account's directory. ## ## Generating SSH keys You can use ssh-keygen to generate a new pair of SSH keys: | ```console server> ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: cb:3c:a0:39:69:39:ec:35:d5:66:f3:c5:92:99:2f:e1 root@server The key's randomart image is: +--[ RSA 2048]----+ | | | | | | | . = | | . S = * o | | . = = + + = | | X o = E . | | o + . . . | | . | +-----------------+ ``` | | --- | Warning: With the default settings, using ssh-keygen will overwrite an existing SSH key! As an alternative, with the parameter `-f`, you can specify a different file path. ## ## Upload Please activate the SSH service of your Storage Box within Robot. Afterwards you can upload your public key with the following command for both Storage Box ports: | ```text server> cat ~/.ssh/id_rsa.pub | ssh -p23 uXXXXX@uXXXXX.your-storagebox.de install-ssh-key uXXXXX@uXXXXX.your-storagebox.de's password: Key No. 1 (ssh-rsa user@host) was installed in RFC4716 format Key No. 1 (ssh-rsa user@host) was installed in OpenSSH format ``` | | --- | After this you can use the public SSH key to login without a password. ## ## Manual You can also upload your key manually. Therefor please use the following guides: ### ### Extended SSH Service on Port 23 (SFTP/Rsync/BorgBackup) Port 23 uses the one-line OpenSSH format of the public key. #### #### Upload with ssh-copy-id (OpenSSH 8.5+) You can use `ssh-copy-id` to upload the new key: | ```text ssh-copy-id -p 23 -s uXXXXX@uXXXXX.your-storagebox.de ``` | | --- | #### Upload without ssh-copy-id / Manually If you have an older OpenSSH client software, you can upload the public key also manual: | ```text ssh -p 23 uXXXXX@uXXXXX.your-storagebox.de mkdir .ssh scp -P 23 .ssh/id_rsa.pub uXXXXX@uXXXXX.your-storagebox.de:.ssh/authorized_keys ``` | | --- | ### ### SSH Service on Port 22 (SFTP) For the SSH service on port 22, you must convert your public key into the RFC4716 format and then upload it. #### #### Converting your key to RFC4716 format To convert the public SSH key into the correct format, enter the following command: `` | `ssh-keygen -e -f .ssh/id_rsa.pub > .ssh/id_rsa_rfc.pub` | | --- | ` ` The public SSH key should now look like the one below: | ```console server> cat .ssh/id_rsa_rfc.pub ---- BEGIN SSH2 PUBLIC KEY ---- Comment: "" AAAAB3NzaC1yc2EAAAABIwAAAQEAz+fh731CVfH3FPM0vK5hX7NT5HogdBEQ4ryGJIeVMv mCQJWwrFtdWh1pXMyXsYzXq1xbjILgCZGn+H0qUBKopJaa/Pzsw5U0UyRgiFhU2k0eiHUq pkiixTbHcLsCj3kjAv5i07wZJ/ot246hLQD1PtSQtcX7nHvhdhenOTGO+ccpM2KEdX1E64 eaTtO9Bf7X4OTXnRxS7tjYH9sls5DOunpvoIZLvbmcVw1+wMdJBXOAU6/tnkN5N3mYE4Hu JjnRtBAI9MS9Tt3DNAp1K/udUHA6hfYf08fxYs9uwsCM793b7FczmVvHEIwIKszG7Jwiwo Dqit4EExR8bNNCeD6D3Q== ---- END SSH2 PUBLIC KEY ---- ``` | | --- | #### #### Upload Now upload the created file: | ```text echo "mkdir .ssh" | sftp uXXXXX@uXXXXX.your-storagebox.de scp .ssh/id_rsa_rfc.pub uXXXXX@uXXXXX.your-storagebox.de:.ssh/authorized_keys ``` | | --- | ### ### Test Depending on which SSH key format you have uploaded, you should be able to log in without a password on port 22 and/or 23: | ```console sftp -P <22 or 23> @.your-storagebox.de Connected to .your-storagebox.de. sftp> quit ``` | | --- | **Related service:** [cloud storage space](https://www.hyyat.com/%d8%b5%d9%86%d8%af%d9%88%d9%82-%d8%a7%d9%84%d8%aa%d8%ae%d8%b2%d9%8a%d9%86/) from Hyyat Host, with technical support that replies within 24 hours. **Related guides** - [Create a snapshot of the storage box from the client area](https://www.hyyat.com/knowledgebase/%d8%a5%d9%86%d8%b4%d8%a7%d8%a1-%d9%84%d9%82%d8%b7%d8%a9-%d9%85%d9%86-%d8%b5%d9%86%d8%af%d9%88%d9%82-%d8%a7%d9%84%d8%aa%d8%ae%d8%b2%d9%8a%d9%86-%d9%85%d9%86-%d9%85%d9%86%d8%b7%d9%82%d9%87-%d8%a7%d9%84/) - [View storage box data from the client area](https://www.hyyat.com/knowledgebase/%d8%b9%d8%b1%d8%b6-%d8%a8%d9%8a%d8%a7%d9%86%d8%a7%d8%aa-%d8%b5%d9%86%d8%af%d9%88%d9%82-%d8%a7%d9%84%d8%aa%d8%ae%d8%b2%d9%8a%d9%86-%d9%85%d9%86-%d9%85%d9%86%d8%b7%d9%82%d9%87-%d8%a7%d9%84%d8%b9%d9%85/) - [Access with SFTP/SCP](https://www.hyyat.com/knowledgebase/%d8%a7%d9%84%d9%88%d8%b5%d9%88%d9%84-%d8%a8%d8%a7%d8%b3%d8%aa%d8%ae%d8%af%d8%a7%d9%85-sftp-scp/) - [login the storage box from the customer area](https://www.hyyat.com/knowledgebase/%d8%a7%d9%84%d8%af%d8%ae%d9%88%d9%84-%d8%b9%d9%84%d9%8a-%d8%b5%d9%86%d8%af%d9%88%d9%82-%d8%a7%d9%84%d8%aa%d8%ae%d8%b2%d9%8a%d9%86-%d9%85%d9%86-%d9%85%d9%86%d8%b7%d9%82%d9%87-%d8%a7%d9%84%d8%b9%d9%85/) **Need this service from Hyyat Host?**Our team handles it for you, with support replying to tickets within 24 hours at most.[Server Management](https://www.hyyat.com/en/server-management/)[dedicated server](https://www.hyyat.com/en/dedicated-server/)
