ipa-replica-conncheck - Check a replica-master network connection before installation


ipa-replica-conncheck [OPTION]...


When an IPA replica is being installed a network connection between a replica machine and a replicated IPA master machine has to be prepared for master-replica communication. In case of a flawed connection the installation may fail with inconvenient error messages. A common connection problem is a misconfigured firewall with closed required port on a replica or master machine.

The connection is checked by running a set of tests from both master and replica machines. The program is incorporated to ipa-replica-install(1) but can be also run separately.



This set of options is used when the connection check is run on a prepared IPA replica machine.

Remote master machine address
Automatically log in to master machine and execute the master machine part of the connection check. The following options for replica part are only evaluated when this option is set
The Kerberos realm name for the IPA server
KDC server address. Defaults to MASTER
Authorized Kerberos principal to use to log in to master machine. Defaults to admin
Password for given principal. The password will be prompted interactively when this option is missing


This set of options is used when the connection check is run on a master machine against a running ipa-replica-conncheck(1) on a replica machine.

Remote replica machine address


Include in a check also a set of dogtag connection requirements. Only needed when the master was installed with Dogtag 9 or lower.
The hostname of this server (FQDN). By default the result of getfqdn() call from Python's socket module is used.
Print debugging information
Output only errors


Run a replica machine connection check against a remote master If the connection to the remote master machine is successful the program will switch to listening mode and prompt for running the master machine part. The second part check the connection from master to replica.
Run a master machine connection check part. This is either run automatically by replica part of the connection check program (when -a option is set) or manually by the user. A running ipa-replica-conncheck(1) in a listening mode must be already running on a replica machine.
Run a replica-master connection check. In case of a success switch to listening mode, automatically log to in a realm EXAMPLE.COM with a password password and run the second part of the connection check.


0 if the connection check was successful

1 if an error occurred
