Make sure that your /sys link and the links under /usr/include correctly point to the sources that were used to compile the kernel, then do a cd /usr/src/sbin/arp; make clean depend && make all; ./obj/arp -a and see if that helps. > Not in my version...

I've tried it: But what they can't do is change the ownership or mode. Programs which attempt to use ptys should perform perform the following sequence of actions before using them: - open master - chmod - chown - revoke slave - open slave It would be slightly cleaner if we supported an frevoke() call like AIX does, but that would be rather difficult. (frevoke() under AIX maps to vgoneall_except_this_one() in BSD...) -GAWollman -- Garrett A.
