Accounts in Advanced SSH Server settings. The security context can be configured either in the virtual account settings entry, or in a virtual group as a default for virtual users.To use EFS with virtual accounts, you must configure their security context to be a Windows local or domain account which you control. You must know the password for this account. For the virtual accounts to access EFS-encrypted files, you must configure the password for the Windows account that provides the security context in the SSH Server's password cache. This is done using the Manage password cache interface in the SSH Server Control Panel.If you ever use administrative privileges to reset the password for this Windows account (i.e. not a graceful password change), EFS-encrypted files will be lost.Do not use EFS with virtual accounts that use the default security context provided by the SSH Server. This is the BvSsh_VirtualUsers account if you installed a default (unnamed) SSH Server instance, or the equivalent BvSsh_... account if you installed a named instance.Windows EFS encryption keys are linked to the Windows account password. The password for the BvSsh_VirtualUsers account is reset by the SSH Server when it starts, or if the password expires. The SSH Server does not persist this password. It is only stored in memory. When the SSH Server stops, EFS-encrypted files which were encrypted under BvSsh_VirtualUsers will become unrecoverable.We suggest whole-disk encryption, e.g. using Windows BitLocker, as a stronger alternative to EFS. It is less fragile and provides greater protection.Q220. What is the difference between SCP and SFTP?SCP and SFTP are different file transfer protocols. SFTP, despite its name, has no relation to FTP. It is a remote file access protocol which provides rich and fine-grained functionality for managing, accessing, and modifying files on an SSH server. SCP is an adaptation of the Unix utility 'rcp' to run over an SSH session, and provides simplistic file transfer operations only.

Present if you have instantiated your host instances from images (AMIs, snapshots, etc.) that contain existing host keys. When a host is cloned, the host key (typically stored in /etc/ssh/ssh_host__key) will also be cloned. As each cloned host will have the same host key, an SSH client cannot verify that it is connecting to the intended host. The script that deploys SingleStore will interpret a duplicate host key as an attempt to deploy to the same host twice, and the deployment will fail. The following steps demonstrate a potential remedy for the duplicate hosts message. Please note these steps may slightly differ depending on your Linux distribution and configuration. sudo rootls -al /etc/ssh/rm /etc/ssh/your-ssh-host-keys>ssh-keygen -f /etc/ssh/ssh-host-key-filename> -N '' -t rsa1ssh-keygen -f /etc/ssh/ssh-host-rsa-key-filename> -N '' -t rsassh-keygen -f /etc/ssh/ssh-host-dsa-key-filename> -N '' -t dsa For more information about SSH host keys, including the equivalent steps for Ubuntu-based systems, refer to Avoid Duplicating SSH Host Keys. As of SingleStore Toolbox 1.5.3, sdb-deploy setup-cluster supports an --allow-duplicate-host-fingerprints option that can be used to ignore duplicate SSH host keys. Network Configuration Depending on the host and its function in deployment, some or all of the following port settings should be enabled on hosts in your cluster. These routing and firewall settings must be configured to: Allow database clients (e.g. your application) to connect to the SingleStore aggregators Allow all nodes in the cluster to talk to each other over the SingleStore protocol (3306) Allow you to connect to management and monitoring tools Protocol Default Port.

To be unaffected by the above limitations.Configuring and RunningQ075. When I try to run the SSH Server or Client installer, nothing happens. How do I start it?Depending on your Windows version, security settings, and how the installer was downloaded, you may need to take an extra step to start it. On Windows Server 2016, right-click the installer executable in Windows Explorer, click Properties, and see if you need to check Unblock on the General tab.Q090. The SSH Server or Client installer warns me that the "installation directory is insecure". Why is it insecure, and what can I do about it?This can happen if you created a custom parent directory such as D:\Programs into which you are installing Bitvise software, but you have not taken care to configure Windows filesystem permissions on that directory.Bitvise software generally runs with high privileges. The SSH Server runs as Local System or equivalent, and the SSH Client can be run by administrators.This means that any other user on the system who is able to rename a Bitvise software installation directory, or to rename or modify files it contains, can use this limited access to give themselves complete administrative access to the system.Recent versions of our software will warn about this situation, and will do so even if the system does not currently have any non-administrative users. If the filesystem permissions are not fixed, a problem can still arise if non-administrative accounts are added later.To fix this problem, you must set up Windows filesystem permissions on the parent directory into which you are installing Bitvise software. For example, if you are installing under D:\Programs, you must ensure that only administrators have the right to rename or modify files and subdirectories under this location.This is achieved by configuring permissions using Windows File Explorer. If you are unfamiliar with Windows permissions, we suggest installing into a standard location such as C:\Program Files or C:\Program Files (x86). Filesystem permissions on these directories are configured properly by default by Windows.Q100.

This can beeliminated by creating a trust relationship between the local and remoteuser accounts. This is not appropriate in all situations, because itessentially makes the accounts equivalent from a security perspective. Anymalicious activity on one account can spread to other systems via thetrust, so take caution and fully understand the implications of settingup trust relationships. To begin setting this up, you need to createan SSH key pair, which consists of public and private key files namedid_rsa and id_rsa.pub, respectively.The public key is copied to the remote system and placed in the$HOME/.ssh/authorized_keys file. Some systems may use the filenameauthorized_keys2 in addition to or instead of authorized_keys.This allows any user in possession of the private key to authenticatewithout a password. We create the key pair using the commandssh-keygen.The files are placed in the proper locations automatically on thelocal system in the $HOME/.ssh directory. Because we already have my remotehome directory mounted, appending the public key to the authorized_keysfile is extra easy. Below are all the steps required (assuming youcreated the equivalent of the randombox_home directory and mounted it):$ cd $HOME$ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/matt/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/matt/.ssh/id_rsa.Your public key has been saved in /home/matt/.ssh/id_rsa.pub.The key fingerprint is:fa:e7:7c:e1:cb:7b:66:8b:67:07:05:99:7f:05:b9:4a matt@myworkstation$ mkdir randombox_home/.ssh$ chmod 700 randombox_home/.ssh$ cat .ssh/id_rsa.pub >> randombox_home/.ssh/authorized_keys$ chmod 600 randombox_home/.ssh/authorized_keysIn the above example,

In mind, exiting from SQLcl or SQL Developer does not close the SSH tunnel. To do this, you’ll need to kill the process as described above.Creating an SSH Tunnel in SQL DeveloperIf you skipped “Creating an SSH Tunnel Command Line above” you may wish to read it just to get an understanding of what is happening. SQL Developer does essentially the same thing as the command line above, but it gives you a user interface to put in all the bits of information. The key is to put the info in the right spots. Rich’s white paper has lots of pictures of each of these steps. I’ll capture the minimum here.1. Run SQL Developer2. Click View > SSH3. At the lower left, right click on SSH Hosts, then choose New SSH HostThis will create an SSH Tunnel definition equivalent to the command line in the previous section.You can then create a database connection with connection type SSH.When you connect to the database you will be prompted for either the key file pass phrase or the SSH user’s password. This will open the SSH tunnel. Alternatively, you can open the SSH tunnel by right clicking on the local port forward under SSH Hosts.Once the tunnel is up and running, it is accessible to anything running on your laptop. Hence, you are able to use SQLcl through the SSH tunnel established within SQL Developer, much as you could use SQL Developer through the SSH command line tunnel.Keep in mind, disconnecting from the database in SQL Developer does not close the SSH tunnel. To do this, you’ll need to right click on the local port forward connection (under SSH Hosts) and disconnect, or exit SQL Developer.Questions on creating an SSH tunnel? Comment below or Contact Us..

Additional resources p11-kit(8), opensc.conf(5), pcscd(8), ssh(1), and ssh-keygen(1) man pages on your system 1.5. Making OpenSSH more secure You can tweak the system to increase security when using OpenSSH. Note that changes in the /etc/ssh/sshd_config OpenSSH server configuration file require reloading the sshd daemon to take effect: # systemctl reload sshd The majority of security hardening configuration changes reduce compatibility with clients that do not support up-to-date algorithms or cipher suites. Disabling insecure connection protocols To make SSH truly effective, prevent the use of insecure connection protocols that are replaced by the OpenSSH suite. Otherwise, a user’s password might be protected using SSH for one session only to be captured later when logging in using Telnet. Disabling password-based authentication Disabling passwords for authentication and allowing only key pairs reduces the attack surface. See the Setting key-based authentication as the only method on an OpenSSH server section for more information. Stronger key types Although the ssh-keygen command generates a pair of RSA keys by default, you can instruct it to generate Elliptic Curve Digital Signature Algorithm (ECDSA) or Edwards-Curve 25519 (Ed25519) keys by using the -t option. The ECDSA offers better performance than RSA at the equivalent symmetric key strength. It also generates shorter keys. The Ed25519 public-key algorithm is an implementation of twisted Edwards curves that is more secure and also faster than RSA, DSA, and ECDSA. OpenSSH creates RSA, ECDSA, and Ed25519 server host keys automatically if they are missing. To configure the host key creation in RHEL, use the [email protected] instantiated service. For example, to disable the automatic creation of the RSA key type: # systemctl mask [email protected]# rm -f /etc/ssh/ssh_host_rsa_key*# systemctl restart sshd In images with the cloud-init method enabled, the ssh-keygen units are automatically disabled. This is because the ssh-keygen template service can interfere with the cloud-init

To be unaffected by the above limitations.Configuring and RunningQ075. When I try to run the SSH Server or Client installer, nothing happens. How do I start it?Depending on your Windows version, security settings, and how the installer was downloaded, you may need to take an extra step to start it. On Windows Server 2016, right-click the installer executable in Windows Explorer, click Properties, and see if you need to check Unblock on the General tab.Q090. The SSH Server or Client installer warns me that the "installation directory is insecure". Why is it insecure, and what can I do about it?This can happen if you created a custom parent directory such as D:\Programs into which you are installing Bitvise software, but you have not taken care to configure Windows filesystem permissions on that directory.Bitvise software generally runs with high privileges. The SSH Server runs as Local System or equivalent, and the SSH Client can be run by administrators.This means that any other user on the system who is able to rename a Bitvise software installation directory, or to rename or modify files it contains, can use this limited access to give themselves complete administrative access to the system.Recent versions of our software will warn about this situation, and will do so even if the system does not currently have any non-administrative users. If the filesystem permissions are not fixed, a problem can still arise if non-administrative accounts are added later.To fix this problem, you must set up Windows filesystem permissions on the parent directory into which you are installing Bitvise software. For example, if you are installing under D:\Programs, you must ensure that only administrators have the right to rename or modify files and subdirectories under this location.This is achieved by configuring permissions using Windows File Explorer. If you are unfamiliar with Windows permissions, we suggest installing into a standard location such as C:\Program Files or C:\Program Files (x86). Filesystem permissions on these directories are configured properly by default by Windows.Q100. After I install Bitvise SSH Server, what do I need to configure before I can start using it?For a basic,

This can beeliminated by creating a trust relationship between the local and remoteuser accounts. This is not appropriate in all situations, because itessentially makes the accounts equivalent from a security perspective. Anymalicious activity on one account can spread to other systems via thetrust, so take caution and fully understand the implications of settingup trust relationships. To begin setting this up, you need to createan SSH key pair, which consists of public and private key files namedid_rsa and id_rsa.pub, respectively.The public key is copied to the remote system and placed in the$HOME/.ssh/authorized_keys file. Some systems may use the filenameauthorized_keys2 in addition to or instead of authorized_keys.This allows any user in possession of the private key to authenticatewithout a password. We create the key pair using the commandssh-keygen.The files are placed in the proper locations automatically on thelocal system in the $HOME/.ssh directory. Because we already have my remotehome directory mounted, appending the public key to the authorized_keysfile is extra easy. Below are all the steps required (assuming youcreated the equivalent of the randombox_home directory and mounted it):$ cd $HOME$ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/matt/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/matt/.ssh/id_rsa.Your public key has been saved in /home/matt/.ssh/id_rsa.pub.The key fingerprint is:fa:e7:7c:e1:cb:7b:66:8b:67:07:05:99:7f:05:b9:4a matt@myworkstation$ mkdir randombox_home/.ssh$ chmod 700 randombox_home/.ssh$ cat .ssh/id_rsa.pub >> randombox_home/.ssh/authorized_keys$ chmod 600 randombox_home/.ssh/authorized_keysIn the above example,
