[Freeipa-users] Original master lost, cannot create additional CA clones

Wed Mar 22 14:21:35 UTC 2017

Hi David,
   These two servers and in separate datacenters, and my networking team closed port 80 at the perimeter on me. If I run with the conncheck, the replica install will fail because of this:

----------------------------------------------------------------------------------------------------
[root at ipasrv001 ~]# ipa-replica-install --no-ntp --setup-ca replica-info-ipasrv001.itec.suny.edu.gpg 
Directory Manager (existing master) password: 

Run connection check to master
Check connection from replica to remote master 'ipasrv201.itec.suny.edu':
   Directory Service: Unsecure port (389): OK
   Directory Service: Secure port (636): OK
   Kerberos KDC: TCP (88): OK
   Kerberos Kpasswd: TCP (464): OK
   HTTP Server: Unsecure port (80): FAILED
   HTTP Server: Secure port (443): OK
   PKI-CA: Directory Service port (7389): OK
Port check failed! Inaccessible port(s): 80 (TCP)
Connection check failed!
Please fix your network settings according to error messages above.
If the check results are not valid it can be skipped with --skip-conncheck parameter.
----------------------------------------------------------------------------------------------------

I have manually verified the ipasrv201 can reach ipasrv001 via ports 389, 636, 88, 464, 443, and 7389 tcp.
There is another replica, ipasrv003, in the same datacenter as ipasrv001. These two servers can communicate over port 80/tcp, and I have tried preparing the replica info from ipasrv003 without success. (Same failure with ca-setup.) I have also tried disabling the local firewall an ipasrv001 in case the install was attempting to access a port listening on the external interface (as opposed to loopback). At this point, I believe the network is inconsequential to the problem.

Thank you for the input,
Paul Brennan

While those original issues have since been resolved, I am having difficulty replacing the system. I can create a new replica, but I cannot use the '--setup-ca' option, nor can I run 'ipa-ca-install'. I have been working on this for quite some time, and seem to be going in circles. Any help would be greatly appreciated.

Hello Paul,
is there a reason you run ipa-replica-install with --skip-conncheck option?
Does it fail with the same error when you run with connection check?
There might be some closed ports on ipasrv201's firewall that cause this fail
and connection check would discover this. But it's just my wild guess.
