Caused by this: RCS file: /home/ncvs/src/sbin/ping/ping.c,v ... ---------------------------- revision 1.41 date: 1998/08/26 18:51:37; author: des; state: Exp; lines: +1 -13 Remove -c restrictions from previous commit. ---------------------------- revision 1.40 date: 1998/08/26 01:58:39; author: dillon; state: Exp; lines: +38 -11 (well tested at BEST): -i option can now take FP values (e.g. -i 0.1), extremely useful for networking testing. Other options secured from user-level D.O.S. attacks. -f, -s now root-only. -i wait times < 1.0 root-only. -c count limited to 100 and defaults to 16 when ping run by non-root user. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
