Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

For each NFS mount, disable suid programs and device access. List the current NFS mounts: lsnfsmnt -l | /usr/bin/egrep -v "^Name" | /usr/bin/grep -v "nosuid" | while read remote server mntpnt rest; do chnfsmnt -d ${remote} -f ${mntpnt} -h ${server} -y -z done lsnfsmnt -l | /usr/bin/egrep -v "^Name" | /usr/bin/grep -v "nodev" | while read remote server mntpnt rest; do chnfsmnt -d ${remote} -f ${mntpnt} -h ${server} -y -z done NOTE: The NFS mount needs is re-mounted automatically by chnfsmnt. NOTE: The second loop might not do anything as both loops set both nosuid (-y) and nodev (-z)
