Ssh PreferredAuthentications

When you're connecting to a remote server via SSH, your SSH client will try different authentication methods before settling for a usable method, with password normally being the final option. This is defined by the PreferredAuthentications that could be set in the SSH client configuration file The SSH protocol has numerous authentication methods. The password and keyboard-interactive are two of them. The password authentication is a simple request for a single password. There's no specific prompt sent by the server $ ssh -o PreferredAuthentications=password,keyboard-interactive my-host root@my-host's password: Password: Permission denied (gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive). UPDATE (2018-04-09): Das folgende ist aus dem SSH: TDG-Buch ersichtlich, das in der Antwort von Jouell erwähnt wird . keyboard-interactiveDie Benutzerauthentifizierung dient hauptsächlich dazu, die. Das SSH-Protokoll verfügt über zahlreiche Authentifizierungsmethoden. Das Passwort und Keyboard-Interactive sind zwei davon. Die Kennwortauthentifizierung ist eine einfache Anforderung eines einzelnen Kennworts. Es wird keine spezielle Aufforderung vom Server gesendet

The ssh client uses the PreferredAuthentications option in the ssh config file to determine this. From man ssh_config (see it online here): PreferredAuthentications Specifies the order in which the client should try protocol 2 authentication methods. This allows a client to prefer one method (e.g. keyboard-interactive) over another method (e.g. password). The default is: gssapi-with-mic,hostbased,publickey, keyboard-interactive,passwor PreferredAuthentications. Specifies the order in which the client should try protocol 2 authentication methods. Protocol. Specifies the protocol versions in order of preference. The possible values are '1' and '2'. Multiple versions must be comma-separated. Use of protocol version 1 is NOT RECOMMENDED for security reasons ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no [email protected] If you don't have password authentication enabled, you can change that by clicking on the server in your BitLaunch control panel, selecting Access, and entering a password ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no example.com You need to make sure that the client isn't configured to disallow password authentication. Shar

When you use SSH keys to authenticate to the GitLab remote server, you don't need to supply your username and password each time. Prerequisites. To use SSH to communicate with GitLab, you need: The OpenSSH client, which comes pre-installed on GNU/Linux, macOS, and Windows 10 1 Answer1. If you override ssh_args in ansible.cfg to -o PreferredAuthentications=publickey is added to the ssh command line but this doesn't replace -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey PreferredAuthentications=password - The methods available for authentication are like GSSAPI-based authentication, host-based authentication, public key authentication, challenge response authentication, and password authentication Here, PreferredAuthentications=password make ssh to use password as the authentication method. The methods available for authentication are: GSSAPI-based authentication, host-based authentication, public key authentication, challenge-response authentication, and password authentication

Hier ein Auszug von Optionen, welche die Public Key Authentication beeinflussen können: AuthorizedKeysFile; PreferredAuthentications; PubkeyAuthenticatio

PreferredAuthentications specifies the order of methods to try. The default generally has five to six options listed with Kerberos first, keys in the middle, and password last. If I know I need to be prompted for a password, such as when copying a new public key to a host, I use -o PreferredAuthentications=password $ ssh -o PreferredAuthentications=none localhost Permission denied (publickey). If password is not present in supported methods in brackets above, that means ssh server does not support password based authentication. Edit PasswordAuthentication value in sshd_config. Open /etc/ssh/sshd_config using sudo $ sudo vi /etc/ssh/sshd_config Change PasswordAuthentication value to yes. PreferredAuthentications password. You can set the IdentityFile parameter for other servers you are connecting to in the ~/.ssh/config so you'll both connect to them more quickly and avoid the risk of too many failed authentication attempts.

  2. Specifies that ssh(1) should only use the configured authentication identity and certificate files (either the default files, or those explicitly configured in the ssh_config files or passed on the ssh(1) command-line), even if ssh-agent(1) or a PKCS11Provider or SecurityKeyProvider offers more identities
  3. It is perfectly valid for an SSH server to REQUIRE that the client provide a publickey AND a password, or more commonly, that the client provide a publickey AND a 2-factor OTP via keyboard-interactive. Consider the sshd_config configuration: AuthenticationMethods publickey,password. And ssh_config: PreferredAuthentications=publickey,passwor
  4. ssh_args = -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey,keyboard-interactive -o ControlMaster=auto -o ControlPersist=60s``` I spent a whole day stuggling to get this to work. Thanks to the comment from @mgresko I now can run my playbooks. I also have an ssh + duo setup
  5. ssh [email protected] 'chmod 400 ~/.ssh/authorized_keys' Using the SSH key to log in. Now that you have installed the key on the server, it's time to log in. If you have the key in the default location, you simply need to log in as usual: ssh [email protected] On the other hand, if you have the private key in a custom location, you should set the path with the -i switch: ssh-i ~/my-key.
  6. It will contact the target server over ssh several times for a single task and possibly for every items in that task. Meanwhile, unless you moved away from the default settings, ansible should re-use the same master ssh session avoiding most of the ssh handshake traffic after the first connection is done. - Zeitounator Jun 4 at 16:0

  1. scp copies files between hosts on a network. It uses ssh (1) for data transfer, and uses the same authentication and provides the same security as a session. The scp protocol requires execution of the remote user's shell to perform glob (3) pattern matching. scp will ask for passwords or passphrases if they are needed for authentication
  2. Optimizing SSH PreferredAuthentications. Another thing that has effect on speed is the Authentication methods SSH will try to use while connecting. If you use only public keys for ssh connection with the desired hosts, you could add the following additional option PreferredAuthentications=publickey to your ssh_args (ansible.cfg -> [ssh_connection]) Now your config line should look like.
  3. The options are as follows: -4 Forces ssh to use IPv4 addresses only. -6 Forces ssh to use IPv6 addresses only. -A Enables forwarding of connections from an authentication agent such as ssh-agent (1). This can also be specified on a per-host basis in a configuration file. Agent forwarding should be enabled with caution

SSH-Verbindungen recyceln. In aktuellen SSH-Versionen (ab 4.0) gibt es die Möglichkeit, SSH-Verbindungen wiederzubenutzen: Hat man bereits eine Shell auf einem entfernten Rechner offen und will dann z.B. scp benutzen, um etwas dorthin zu kopieren, wird die gleiche Verbindung benutzt. Dadurch muss man sich nicht noch einmal an dem anderen Rechner authentifizieren, was einiges an Zeit spart eval $(ssh-agent -s) ssh-add <directory to private SSH key> Save these settings in the ~/.ssh/config file. For example: # GitLab.com Host gitlab. com PreferredAuthentications publickey IdentityFile ~/. ssh / gitlab_com_rsa # Private GitLab instance Host gitlab. company. com PreferredAuthentications publickey IdentityFile ~/. ssh / example_com_rs Host git.example.com Preferredauthentications publickey IdentityFile ~/.ssh/example_com_id_rsa Host * AddKeysToAgent yes UseKeychain yes IdentityFile ~/.ssh/id_rsa. The host is the system you need access to. It could be a git server or some other resource. Wildcards work here so if you need to access all resources on s particular domain, you would handle that here. There are a lot of things.

Scenario-1: Use separate expect script. Scenario-2: Use expect inside bash script. Scenario-3: Perform scp with password using expect. Method 2: Use sshpass to provide password with SSH 10 sftp command examples. So, basically FTP can be used in limited cases or on the networks that you trust. Over the period of time SCP and SSH addresses this security ambiguity and added an encrypted secure layer while transferring data between remote computers.. SFTP (Secure File Transfer Protocol) runs over SSH protocol on standard port 22 by default to establish a secure connection However, this may not be the case in some environments. The workaround would be to modify /etc/ansible/hosts and add an entry like this: ansible_user=<user>. where <user> is the user that exists in the target host and for the one you exchanged ssh keys for. After that you should be able to connect and get this output: $ ansible -m.

The full path to that folder would be /home/customer/.ssh. Find a file named config in it, or create a new file with that name if it does not exist.

Before you can push your changes to a GitLab server you need a secure communication channel for sharing information. The SSH protocol provides this security and allows you to authenticate to the GitLab remote server without supplying. Try > #ssh -o PreferredAuthentications=password > and paste the output PreferredAuthentications doesn't seem to be a correct option. Nor does it show up in /etc/ssh/ssh_config or /etc/ssh/sshd_config. Perhaps this is because I used the empty string when creating keys? b Syntax. sftp performs all operations over an encrypted ssh session. It uses many of the features of ssh, such as public key authentication and data compression..

This enables forwarding keys loaded into ssh-agent to remote SSH connections. Check which keys are loaded currently using ssh-add -l, and add any additional required keys using ssh-add ~/.ssh/key-here Ansible where do PreferredAuthentications SSH settings come from?Helpful?

It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication..
