I think this "ypmaster -m" error happens from revision 1.15 of ypwhich.c
struct ypmaplist is defined in <rpcsvc/yp.h> and <rpcsvc/yp_prot.h>
and they are incompatible.
<<yp.h>>
struct ypmaplist {
mapname map;
struct ypmaplist *next;
};
<<yp_prot.h>>
struct ypmaplist {
char ypml_name[YPMAXMAP + 1];
struct ypmaplist *ypml_next;
};
struct ypmaplist of yp_prot.h is used in ypwhich.c,
while yp_maplist function returns struct ypmaplist of yp.h.
I could find this with gdb ypwhich.
<<revision 1.14>>
