RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Erinn Looney-Triggs 2014-08-09 20:01:50 UTC 
Description of problem:
When a system has more than one IP address as in the case of a dual stacked system, and when using an external CA, the initial ipa-server-install will go fine as it prompts you for the IP address to use. However, when attempting to finish the install using the ipa-server-install --external_cert_file=/path/to/signed_certificate --external_ca_file=/path/to/external_ca_certificate

the installer will fail with: 
The server hostname resolves to more than one address:
  IPv6 Address
  IPv4 Address
Please use --ip-address option to specify the address

However, the installer does not appear to respect the --ip-address option at this point as attempting to add that flag results in the exact same error again.


Version-Release number of selected component (if applicable):
ipa-server-3.3.3-28.el7.x86_64
Comment 2 Martin Kosek 2014-08-11 13:47:17 UTC 
Thanks for the bug report. It looks very related to Bug 1125415 which is now scheduled for next upstream release and which we would like to have in next RHEL minor version.

Until this is fixed, would you be able to have just IPv4 address on your IPA server? You should be able to install them. Would this work as a temporary workaround?
Comment 3 Erinn Looney-Triggs 2014-08-11 17:11:40 UTC 
Well I was able to work around the issue by using the --ip-address=<IPv6 address> on the initial run through, and then the second ip-server-install command went through.

I think this bug is related in spirit, but I think this is also a bug in the second run of ipa-server-install where in order to work around this it should accept the --ip-address flag, or the first run should set a variable somewhere that the second run can pick up.

Comment 4 Martin Kosek 2014-08-12 08:24:49 UTC 
Right. I will link this Bugzilla to upstream ticket
https://fedorahosted.org/freeipa/ticket/3575
which is being worked on right now to make sure this use case is covered as well.
Comment 6 Rob Crittenden 2014-08-18 13:23:42 UTC 
Note that this is more about ignoring options passed to the second installer run. The reason is that for some things it is too late to change things once the first run is done because we've already started installing some things. It may be that we can somehow mark some options as being able to override on the second run, but it is probably safer/better to simply not allow it.

This could be annoying though, as getting a CSR signed by an external CA can be hard enough and having to do it multiple times due to having to start over from scratch even more so.
Comment 7 Martin Kosek 2014-08-18 16:04:48 UTC 
David, please see advise above when implementing this one.

Comment 13 Scott Poore 2015-01-21 02:10:40 UTC 
Did this bug only affect IPv6 interfaces?

I've tried reproducing the issue on RHEL7.0 with ipa 3.3.3 on a VM.  I set up a second virtual network on the host and added a second interface to the guest.

[root@rhel7-3 RootCA]# ip addr

    inet6 fe80::5054:ff:feb4:bcec/64 scope link 
       valid_lft forever preferred_lft forever

[root@rhel7-3 RootCA]# netstat -rn

I don't see the specified error from the original description though.  The first time I tried, it installed IPA normally.  But, then I realized I had an /etc/hosts entry.  I uninstalled and reinstalled without that and got this:

[root@rhel7-3 RootCA]# ipa-server-install --setup-dns --forwarder=192.168.122.1     -r EXAMPLE.TEST -a Secret123 -p Secret123     --external_cert_file=/root/ipa.crt     --external_ca_file=/root/ipacacert.asc -U

So, my real questions:

1. Can I reproduce on KVM guest with two virtual networks?

2. Can I reproduce with IPv4 only or do I need to use IPv6 instead?

Thanks,
Scott
Comment 14 Martin Kosek 2015-01-21 11:41:20 UTC 
Jan, do you know?
Comment 15 Jan Cholasta 2015-01-21 11:44:17 UTC 
I have no idea. David?
Comment 16 David Kupka 2015-01-21 16:11:41 UTC 
To answer your questions:
1. You should be able. When I was working on this I used kernel module "dummy" to create virtual interface. 
2. Yes, multiple IPv4 addresses are enough.

Unfortunately I'm unable to reproduce the behaviour you described. Could you please provide all steps you've done? Or at least /var/log/ipaserver-install.log?
Comment 17 Scott Poore 2015-01-22 01:30:30 UTC 
FYI, I'd originally misread this bug as dual-homed...not dual stacked.  Not sure if that makes any difference with this bug or not but, if it requires specific IPv6 setup I may need more info to setup test.

* From virt-manager, I created a new NAT virtual network.
* Booted up a RHEL7.0 VM and added /etc/sysconfig/network-scripts/ifcfg-eth1 configured for new network.
* Note that my KVM host is RHEL6 running dnsmasq with the hostname in /etc/hosts for resolution.
* Checking network as is:

Comment 18 Scott Poore 2015-01-22 02:27:49 UTC 
David,

Thanks for looking into this.  I think you can skip it for now though.  I was able to reproduce this by adding an IPv6 entry for the hostname to /etc/hosts so dnsmasq picked that up too.

Then I get expected failure when trying to use --ip-address the second time through:

[root@rhel7-5 ~]# ipa-server-install --external_cert_file=/root/ipa.crt --external_ca_file=/root/ipacacert.asc --ip-address=192.168.122.75 -a Secret123 -p Secret123

The log file for this installation can be found in /var/log/ipaserver-install.log

This program will set up the IPA Server.

This includes:
  * Configure a stand-alone CA (dogtag) for certificate management
  * Configure the Network Time Daemon (ntpd)
  * Create and configure an instance of Directory Server
  * Create and configure a Kerberos Key Distribution Center (KDC)
  * Configure Apache (httpd)
  * Configure DNS (bind)

Warning: skipping DNS resolution of host rhel7-5.example.com
The server hostname resolves to more than one address:
  192.168.122.75
  fe80::5054:ff:fe64:26ab
Please use --ip-address option to specify the address


Thanks again,
Scott

Verified.

Version ::

ipa-server-4.1.0-16.el7.x86_64

Results ::

First I setup a RHEL7.1 KVM guest on a host with dnsmasq default setup on RHEL6.  The I added added the IPv6 address to /etc/hosts entry for the guest and did a kill -HUP on dnsmasq processes.

You'll notice the first round of ipa-server-install selects the IP address to use for install.

Restarting the web server
==============================================================================
Setup complete

Next steps:
	1. You must make sure these network ports are open:
		TCP Ports:
		  * 80, 443: HTTP/HTTPS
		  * 389, 636: LDAP/LDAPS
		  * 88, 464: kerberos
		  * 53: bind
		UDP Ports:
		  * 88, 464: kerberos
		  * 53: bind
		  * 123: ntp

	2. You can now obtain a kerberos ticket using the command: 'kinit admin'
	   This ticket will allow you to use the IPA tools (e.g., ipa user-add)
	   and the web user interface.

Be sure to back up the CA certificate stored in /root/cacert.p12
This file is required to create replicas. The password for this
file is the Directory Manager password
Comment 21 Scott Poore 2015-01-23 15:31:00 UTC 
David pointed out that I needed to test with a global IPv6 address and I do see a different output.


The first part of the ipa-server-install here shows the difference.  It includes both address when I use a global instead of link-level IPv6 address.

/usr/sbin/ipa-server-install --external-cert-file=/path/to/signed_certificate --external-cert-file=/path/to/external_ca_certificate


Now setup test external NSSDB CA:
