![]() If a host is not set up correctly, the system will display an error message with the instructions to setup the host.Īlternatively, you can also verify that the SE hosts have been setup as a part of the SSH user configuration. This verification can be done as a part of adding a server in the Linux cloud by clicking ? icon. You can verify if the host has been setup with the SSH credentials correctly from the NSX Advanced Load Balancer Controller. By default, this will create a 3072 bit RSA key pair. To do this, we can use a special utility called ssh-keygen, which is included with the standard OpenSSH suite of tools. PubKeyAuthentication based login is already set up.įinished configuration Verifying if SE Hosts are Setup The first step to configure SSH key authentication to your server is to generate an SSH key pair on your local computer. Updating the authorized keys under /etc/ssh/authorized_keys_newuser The output of the script is piped to sudo bash. This command invokes an API to download a script that has the public key credentials of the user associated with the cloud and the necessary steps to set up the user in this host. To prepare a host where SEs are launched, login to the host as a user that has sudo privileges and run the following command: curl -ks | sudo bash ![]() The Name field is the user name that Controller will try to log into the Linux server with, hence provide the real user name. Create the SSH key pair Using the ssh-keygen tool, lets now create a new key pair for scanman to use. Select Generate SSH Key Value Pair radio button and click Generate SSH Key Pair.Ĭlick Save option. Create the a user and the directory to hold the users key Create a new user, for this example we will call that user scanman useradd scanman mkdir /home/scanman/.ssh 2. The following are the steps to create new SSH user: A unique account is not required for each SE host (The account serves a similar purpose to the well-known secret in a routing protocol topology). If there are more than one account, you can use the same account for all the SE hosts. If any SSH users have already been added to the Controller, they will be listed here. ![]() Navigate to Administration > Settings, and click SSH Key Settings. You can copy the user’s public key so it can be pasted into a command line on each of the SE hosts. Use this section even if the SSH user has already been added. You can create an SSH account on the Controller, or an existing account can be used by adding its user name and importing its keys. On the Controller, add the SSH user and the user’s public-private key pair. Adding SSH User to the NSX Advanced Load Balancer Controller The SSH user and key are used by the Controller to log onto the SE host, transfer the Docker container for the SE onto the host, and start the SE within the Docker container. While installing NSX Advanced Load Balancer for a Linux server cloud, part of the deployment process for a new SE is to add an SSH user to the Controller, then add the same user and its public key to the SE host. A part of this process takes place on the Controller while the other part takes place on each SE hosts. But scp is very useful when you want to just toss a file and not do the whole SFTP process manually from the command line.This section describes how to set up SSH on the Controller and each SE host so that the Controller can log onto the SEs in a Linux server cloud. Now if the remote server does not allow SSH and only SFTP, then SFTP is the way to go. But you could also specify a path like /this/path/right/here in the local to remote example: scp cool_stuff.txt the remote to local example right here: scp /this/path/right/here just indicates the immediate directory path such as the one you are in right at the moment you run the command or the immediate path that the remote user on the destination server has. And if you are doing this with multiple files, just use a wildcard ( *) like you would for a normal cp command.Īlso, the. That command would copy the remote file cool_stuff.txt to whatever local directory you are in. So if the file was cool_stuff.txt and your username on the remote sever is sanjeev and the destination sever is, the command would be: scp cool_stuff.txt the source could also be remote so you could do this to do the opposite of the above example: scp. Of course replace the bracketed, and to match your local settings. ![]() Use scp (secure copy) like this: scp server]. ![]()
