I tested all patches (3.6, 18, 19), but I think some work still needs to
1) What about adding /sbin/ip package to Requires in spec? I thought
there was an agreement to do it.
2) When I run `ipa-server-install --ip-address=$ADDR`, and $ADDR is
invalid address (e.g. $ADDR==foo), loopback address (e.g.
$ADDR==127.0.0.1) or just another that the local address (e.g.
$ADDR==188.8.131.52) the installer always fails with "the hostname

I think we may want a different error message in those 3 cases - it
should be easy to do it now, with the improved IP handling.
It looks like the print statements from verify_ip_address doesn't
actually print anything to the user. Will look onto that.
3) When I pass netmask to ipa-server-install --ip-address=$ADDR, the
installation always fails with the above message. Even though I took the
addr+netmask from "/sbin/ip address" output.
Works for me. Please make sure you've added your hostname to /etc/hosts.
I think I had. But I will recheck when you send a fix.
4) I miss IP address checks in --ip-address and --forwarder parameters
of ipa-dns-install script. I can pass invalid or local addresses to
these parameters. This breaks Bind configuration.
--ip-address is checked, but --forwarder is not. Will fix that.
Ok, I will recheck both of them when you do.
5) I think we may want to check also for local address in
#ipa host-add $HOST --ip-address=127.0.0.1
6) I couldn't add IP address with netmask in host module:
# ipa host-add $HOST --ip-address=10.16.78.102/22
ipa: ERROR: invalid 'ip_address': invalid IP address
The patches are for the installer, as are the tickets they fix, so these
issues are out of scope. A new ticket should be opened for them.
You touched this parameter in your patches, that's why I tested it. I
created a new ticket for it:
Ticket 1234, yey :-)
7) Why is the _ParsedIPAddress named with a leading underscore? It's not
really an internal use since it is returned by new IP handling functions
and used in other modules.
_ParsedIPAddress is not for public use. The fact that object of this
class is returned by parse_ip_address doesn't really matter - this is
Python, not C++ or Java.
Hm, snappy... And I was wondering why my /usr/bin/java doesn't want to
run FreeIPA, now I know - it's because its Python.
Patch updated. Requires patch 18.1
