Have been using `ping` to test connectivity from our clients to the various IPA servers around the WAN before running an ldapsearch to pull some details about the client from the LDAP database. Several new VLAN's have now come online that do not permit ping traffic to be transmitted outside the VLAN, so clients on these LAN's think they can't see any of my IPA servers and then fail the domain join during the kickstart phase. Wondering if there's a consensus on how to check connectivity to IPA servers on the network? Something that I can use during the kickstart post-install phase.
Current effort is:
wget --timeout=1 --tries=1 --no-check-certificate https://ipaserver1.example.com and then test $? for result. But this only tests ports 80/443 - which authentication clients wont necessarily have access on. Can I reliably test the other FreeIPA ports? 389, 636,

389: ldapsearch -xLLL -h ipaserver1.example.com -p 389 -s base -b ""

636: LDAPTLS_REQCERT=never ldapsearch -xLLL -H ldaps://ipaserver1.example.com -s base -b ""

88, 464? These are the ports that clients have to be allowed access to the IPA servers.
