OK, this is what I get upon the following change:
printf("yppasswdd- debug:%s<=>%s\n",mastername,myname);
if (strncmp(mastername, (char *)&myname, sizeof(myname))) {
yp_error("this host is not an NIS master server -- aborting");
exit(1);
}
toots#
rpc.yppasswdd
yppasswdd- debug:toots<=>toots.physik.rwth-aachen.de
rpc.yppasswdd: this host is not an NIS master server -- aborting
toots#
toots# hostname
toots.physik.rwth-aachen.de
So myname is the fully qualified name while mastername is just the .
short name.
