Description Robbie Harwood 2019-01-04 19:30:02 UTC

Hi!  I imagine this has something to do with DNS, but really can't tell what's wrong:

[root@7-3 ~]# hostname
7-3.example.com
[root@7-3 ~]# ipa-client-install -N
7-3 is not a fully-qualified hostname
The ipa-client-install command failed. See /var/log/ipaclient-install.log for more information

Comment 2 Robbie Harwood 2019-01-04 19:37:12 UTC

It seems it was related to DNS somehow.  Adding `192.168.122.110	7-3.example.com 7-3` to /etc/hosts caused the installation to succeed.

So at the very least that error message needs updated.

Comment 3 Rob Crittenden 2019-01-04 20:41:09 UTC

The python call socket.getfqdn() is returning only 7.3 as evidenced by the log message:

2019-01-04T19:27:32Z DEBUG Starting IPA discovery with domain=None, servers=None, hostname=7-3

Comment 4 Alexander Bokovoy 2019-01-29 14:42:57 UTC

https://tools.ietf.org/html/rfc1123#page-13 claims that a hostname starting with a digit is allowed so it might be a bug in our code.

Comment 5 Alexander Bokovoy 2019-01-29 14:45:59 UTC

Christian, could you please check if socket.getfqdn() or glibc has a restriction against RFC1123 section 2.1?

Comment 6 Christian Heimes 2019-01-31 10:44:02 UTC

I'm unable to reproduce the issue on a RHEL 7.6 machine.

I have created an IPA master with DNS and a client with hostname "7-6.ipa.test". The DNS server on master manages the "ipa.test." zone as well as the reverse zone for the client's IP address. The client uses the master's DNS server in /etc/resolv.conf. I haven't added any additional entries to /etc/hosts. socket.getfqdn() returns the correct hostname "7-6.ipa.test". ipa-client-install succeeds with the hostname, too.

Comment 8 Florence Blanc-Renaud 2019-02-15 17:17:33 UTC

Hi Robbie,

could you check the config for hosts: in /etc/nsswitch.conf, /etc/hostname, the output of hostname, hostnamectl, and dig +short -x <IP addr>? The hostname is probably defined as a short name somewhere.
