The symptom is that ypinit simply hangs and does nothing. The reason is that ypxfr tries to contact portmap on the 4.11 machine via IPv6, but on 4.11 portmap only listens on IPv4. A workaround is to delete all AAAA entries from /etc/hosts and stop the name server, such that the rpc call uses only an IPv4 address. >How-To-Repeat: run ypinit -s ... on a FreeBSD6 machine against a FreeBSD4 yp server. >Fix: rpc should cycle through all available host addresses if it cannot reach a host via a specific address (similar to what telnet does). >Release-Note: >Audit-Trail: >Unformatted:
