I am trying to secure the /tmp and /var/tmp directories by doing the following... cd / dd if=/dev/zero of=tmpfile bs=1024 count=1048576 mkfs.ext3 -j /tmpfile mount -o loop,noexec,nosuid,rw /var/tmpfile /tmp chmod 1777 /tmp echo “/var/tmpfile /tmp ext3 loop,rw,noexec,nosuid,nodev 0 0? >> /etc/fstab rm -rf /var/tmp/ ln -s /tmp/ /var/tmp However, when using mount, I get the following error... mount: Could not find any loop device. Maybe this kernel does not know about the loop device? (If so, recompile or `modprobe loop'.) Why is this?
