![]() The usual values are ‘1’ and ‘2’, multiple versions must be comma-separated. Protocol – this option defines the protocol versions ssh should support in order of preference.Use the port number configured in the remote host’s sshd config file. Port – sets the port number to connect on the remote host, the default is 22.User – specifies the user to log in as.HostName – defines the real host name to log into, alternatively, you can use a numeric IP addresses, it is also permitted (both on the command line and in HostName specifications).Open the config file with your favorite editor:Ī detailed explanation of the above ssh configuration options. Remember to use options and values (host aliases, port numbers, usernames and so on) applicable to your server environment. Once you have understood how the ssh client config file works, you can create it as follows. How To Use User Specific SSH Configuration File But it can not override any values of options that where already used in the previous section(s). Here, it applies all the options in this section to the host connection. It proceeds to the last section, Host *, which matches all hosts.then moves to the next host section, Host host2 and finds that the name provided on the command line doesn’t match, so no options are used from here.match the host alias host1 in the config file and applies the options set under the definition header, Host host1.The above ssh command will does the following things: If you execute a ssh command to remotely access host1 like so: Still considering the format above, this is how ssh reads the config file. ![]() The header definition Host * (where * is a pattern – wildcard that matches zero or more characters) will match zero or more hosts.For an option such as ssh_option2=value1 value2, the value value1 is considered first, then value2.The configuration options such as ssh_option1=value1, ssh_option2=value1 value2 apply to a matched host and should be indented for well organized formatting.host1, host2 are simply host aliases to use on the command line, they are not the actual hostnames of the remote hosts.Host host1 – is a header definition for host1, this is where a host specification starts and it ends with the next header definition, Host host2 making a section.The conventional format of ~/.ssh/config is as follows, and all empty lines as well as lines starting with ‘#’ are considered as comments: The above file contains sections defined by hosts specifications, and a section is only applied to hosts that match one of the patterns set in the specification. This file is usually not created by default, so you need to create it with the read/write permissions for only the user. How To Create User Specific SSH Configuration File ![]() The chmod command above implies that only the user can have read, write and execute permissions on the directory as required by ssh settings. Note: In case the directory ~/.ssh does not exist on your desktop system, create it with the following permissions. This is the file we will create and use.īy default, users are authenticated in ssh using passwords, however, you can setup ssh passwordless login using ssh keygen in 5 simple steps.
