/etc/opiekeys permissions?
Good day. Playing with OPIE I've noticed that the /etc/opiekeys have mode 644. As I remember there was a vulnurability related to this permissions for S/Key. But at that times that file was named /etc/skeykeys and it was created with permissions 600, so FreeBSD was not vulnerable to the disctionary attack. But now it seems to be vulnurable again. Are there any programs that are run in non-root mode and they do want to use OPIE? If there is no such programs, why the permissions are so strange? -- rea ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Surely. Great idea! As long as there *is* an equivalent macro that exactly matches the expected behavior, this can work nicely. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

In the linux world, you would simply boot a live cd like knoppix, open a root shell in the live system and chroot into your installed system to get root access without a password.

So maybe if you're running at a higher kernel security level you might need to turn that off. Don't know how though, I never cripple my root access.

Re: How to reset root passwd FreeBSdD4.7
Boot with 1st CD, goto the Fixit Shell (will need 2nd CD). From there you have to manually mount the / filesystem and edit passwd (just clear out the passwd, root::). However, do an fsck on the device first (you may have to reboot afterwards) since if you have any fragmentation following an unclean shutdown, you will not be able to mount the device. -john On Thu, 14 Jul 2005, Vyacheslav Sotnikov wrote: > John Von Essen пишет: > > boot single user... > > > > mount -u / > > mount -a > > > > Then use vipw or passwd to clear out or change root password.
