I have a host that I have been accessing with vncviewer via its fqdn that had only an IPv4 A record. I just added a AAAA IPv6 record, and vncviewer via fqdn stopped working. But worked when I provided the IPv4 address instead. It LOOKS like vncviewer is trying the IPv6 address, eventhough all documentation indicates that it does not support IPv6. Definitely my server is only listening on the IPv4 interface. SSH has a nice -4 option to force using IPv4; there is no similar option for vncviewer. Does anyone have any idea on how to enforce IPv4 usage for IPv6-dead vncviewer? Yes, I DO want IPv6 on this server....
