>Release: FreeBSD 3.0-971022-SNAP i386
>Environment:
FreeBSD NIS slave server
>Description:
If ypxfr is invoked with non-terminal standard input, it assumes that
it is invoked via remote yppush. This is generally not the case
because yppush can also be invoked from cron or some other background
process which has no terminal device associated with standard input.
This false assumption causes ypxfr to attempt a boguc RPC callback
connection and dump out an error through syslog.
>How-To-Repeat:
Issue "ypxfr -h <master_server> passwd > /dev/null" and examine
/var/log/messages.
>Fix:
Apply the following patch to the ypxfr_main.c (revision 1.10)
