Freeipa Generate New Host Key
How do I create a host key file to use with my applications as I can not use system defined /etc/ssh/ssh_host_rsa_key for non-root account under Linux / Unix / Apple OS X / *BSD operating systems?
You need to use a command called ssh-keygen. This command generates, manages and converts authentication keys for ssh. It can create RSA keys for use by SSH protocol version 1 and RSA or DSA keys for use by SSH protocol version 2. he type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will generate an RSA key for use in SSH protocol 2 connections. The -f option specifies the filename of the key file.
Here's my situation: I'm setting up a test harness that will, from a central client, launch a number of virtual machine instances and then execute commands on them via ssh.The virtual machines will have previously unused hostnames and IP addresses, so they won't be in the /.ssh/knownhosts file on the central client. The problem I'm having is that the first ssh command run against a new. The following example demonstrates creating a service principal and keytab on a client host for the HTTP service. In this example, the client host is ipaclient.example.com and the FreeIPA server is ipaserver.example.com: # kinit admin # ipa host-add ipaclient.example.com # ipa service-add HTTP/ipaclient.example.com@EXAMPLE.COM # ipa-getkeytab -s ipaserver.example.com -p.

Why create a new host key files?
You may need a new key file: Generate rsa private key online.
- Your system is compromised.
- Your keys are stolen.
- You forgotten the passphrase.
- Your application need a new host key.
- You can not read the default system key files stored in /etc/ssh/ directory but your non-root application needs key.
- You got an error message which read as “Could not load host key: /etc/ssh/ssh_host_key*”.
ssh-keygen Syntax
The syntax is:
Example
Create a host key file in your $HOME/.ssh/myapp as follows. First, create a directory to store your host key file, enter:$ mkdir -p $HOME/.ssh/myapp
To create a host RSAv2 key file, run:$ ssh-keygen -t rsa -f $HOME/.ssh/myapp/rsa_key_file
Sample outputs:
Type the following commands to verify the keys:$ ls -l $HOME/.ssh/myapp/
Sample outputs:
You can now use keys with your app:$ mycool-app -key $HOME/.ssh/myapp/rsa_key_file -d
ADVERTISEMENTS
- Add, modify and delete an IPA host using IPA API
| Parameter | Choices/Defaults | Comments |
|---|---|---|
| description - | ||
| force |
| Force host name even if not in DNS. |
| fqdn - / required | Can not be changed as it is the unique identifier. | |
| ip_address | Add the host to DNS with this IP address. | |
| ipa_host string | Default: | IP or hostname of IPA server. If the value is not specified in the task, the value of environment variable IPA_HOST will be used instead.If both the environment variable IPA_HOST and the value are not specified in the task, then DNS will be used to try to discover the FreeIPA server.The relevant entry needed in FreeIPA is the 'ipa-ca' entry. If neither the DNS entry, nor the environment IPA_HOST, nor the value are available in the task, then the default value will be used.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_pass string / required | If the value is not specified in the task, the value of environment variable IPA_PASS will be used instead.Note that if the 'urllib_gssapi' library is available, it is possible to use GSSAPI to authenticate to FreeIPA. If the environment variable KRB5CCNAME is available, the module will use this kerberos credentials cache to authenticate to the FreeIPA server.If the environment variable KRB5_CLIENT_KTNAME is available, and KRB5CCNAME is not; the module will use this kerberos keytab to authenticate.If GSSAPI is not available, the usage of 'ipa_pass' is required. Environment variable fallback mechanism is added in Ansible 2.5. | |
| ipa_port integer | Default: | Port of FreeIPA / IPA server. If the value is not specified in the task, the value of environment variable IPA_PORT will be used instead.If both the environment variable IPA_PORT and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_prot string |
| Protocol used by IPA server. If the value is not specified in the task, the value of environment variable IPA_PROT will be used instead.If both the environment variable IPA_PROT and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| ipa_timeout integer | Default: 10 | Specifies idle timeout (in seconds) for the connection. For bulk operations, you may want to increase this in order to avoid timeout from IPA server. If the value is not specified in the task, the value of environment variable IPA_TIMEOUT will be used instead.If both the environment variable IPA_TIMEOUT and the value are not specified in the task, then default value is set. |
| ipa_user string | Default: | Administrative account used on IPA server. If the value is not specified in the task, the value of environment variable IPA_USER will be used instead.If both the environment variable IPA_USER and the value are not specified in the task, then default value is set.Environment variable fallback mechanism is added in Ansible 2.5. |
| mac_address - | If option is omitted MAC addresses will not be checked or changed. If an empty list is passed all assigned MAC addresses will be removed. MAC addresses that are already assigned but not passed will be removed. | |
| ns_hardware_platform | Host hardware platform (e.g. 'Lenovo T61') | |
| ns_host_location | Host location (e.g. 'Lab 2') | |
| ns_os_version | Host operating system and version (e.g. 'Fedora 9') | |
| random_password added in 2.5 |
| Generate a random password to be used in bulk enrollment |
| state - |
| State to ensure |
| update_dns boolean |
| If set 'True' with state as 'absent', then removes DNS records of the host managed by FreeIPA DNS.This option has no effect for states other than 'absent'. |
| user_certificate - | If option is omitted certificates will not be checked or changed. If an empty list is passed all assigned certificates will be removed. Certificates already assigned but not passed will be removed. | |
| validate_certs |
| If set to no, the SSL certificates will not be validated.This should only set to no used on personally controlled sites using self-signed certificates. |
Common return values are documented here, the following are the fields unique to this module:
| Key | Returned | Description |
|---|---|---|
| host dictionary | always | |
| host_diff | if check mode and a difference is found | List of options that differ and would be changed |
