Hi Piotr, Can you clarify what you noticed is not resolvable - the 'engine' FQDN from host0? Thanks, Nadav. On Fri, Apr 28, 2017 at 4:15 PM, Piotr Kliczewski <pkliczew@redhat.com> wrote:
I started to investigate the issue [1] and it seems like there is an issue in Lago setup we use.
During handshake we have a step to verify whether client certificate was issued for a specific host (no such functionality in m2crytpo code base). It works fine when using either ip addresses or fqdns but in this particular setup we use mixed.
When added logging I see that in engine certificate we use 'engine' name which is not resolvable on the host side and the check fails. I posted a patch [2] which fixes IPv4 mapped addresses issue but we need to fix the setup issue.
Thanks, Piotr

Error snippet from VDSM log, this repeats on each connection attempt from Engine side:
<error>

</error>
This means that what we have in the certificate do not match the source address we get. I suspect that we issue the certificate for 192.168.201.3 but when we get ::ffff:192.168.201.3. The change was verified in the env when ipv4 is used. I pushed a revert [1] for now so we can work on fixing the issue.
