[Freeipa-devel] [PATCH] 239 Tolerate UDP port failures in conncheck

[Martin Kosek]

UDP port checks in ipa-replica-conncheck are too strict. The entire
conncheck fails when UDP ports cannot be verified as open. However,
UDP protocol is unrealiable by its nature and the port can also not
be checked if there is an application already bound to it. This can
happen for example when ipa-replica-conncheck is run as a part of
ipa-ca-install and the replica services are thus already running.

This patch changes the behavior of UDP port checks. The conncheck
script now rather reports a warning that UDP port cannot be verified
but does not fail the entire test.
