hello,i did sudo su.. then i changed the perm of hda1 --> chmod a-x , a-r, a-w. i checkd using ls -l and the perms where changed.. i tried to mound the hd using mount /mnt/hda1 and it sill mounted and i was able to read and write, although i have set the perm for all users including root.. i loged out of root to dsl@box and still i was able to do the same thing.. is this a bug or im doing somthing wrong here ?? thanks Posted by mikshaw on Mar. 18 2005,04:59
What was the exact command you used?Typically chmod is done only to files, not to drives. If you did "chmod <mode> /dev/hda1" you are changing only the device file. If you do "chmod <mode> /mnt/hda1" it changes only the mount point. If you want to make a drive read-only, try editing /etc/fstab....add "ro" to the options of hda1 Also, permissions do not apply to root. Posted by Bilal on Mar. 18 2005,06:21
ok .. i cant change the fstab file , as it is part of a read only file system , even if i use the toram option.so how can i do that using the command line. thanks Posted by mikshaw on Mar. 18 2005,13:24
It depends on the filesystem on hda1. For fat32 it would be something like this:sudo mount -t vfat -r /dev/hda1 /mnt/hda1 < http://www.die.net/doc/linux/man/man8/mount.8.html > |
