Knoppix V4 And /grub/boot/menu.lst Permission

[zillah]

When I use Knoppix V4 to edit file , I received this message :

You do not have enough permission to read file://mnt/hdb4/boot/grub/menu.lst

How can I get root previlidge to modify above file ?

[shanenin]

I would do it this way. Open up a terminal, then enter the su command. It will give you root privledges without having to enter a password. now start any editer from the command line. For simple text diting I like nano

nano -w menu.lst

[zillah]

nano -w menu.lst

It did not work :

root@0[knoppix]# nano -W  /mnt/hdb6/boot/grub/menu.lst
bash: nano: command not found
root@0[knoppix]# nano -w  /mnt/hdb6/boot/grub/menu.lst
bash: nano: command not found

[zillah]

Then I found option called "root shell",,,I opened that one and I typed in:

vim /mnt/hdb6/boot/grub/menu.lst,,,,,,,,,,,,,,,,,,,,,,,it did work,,,

nedit /mnt/hdb6/boot/grub/menu.lst,,,,,,,,,,,,,,,,,,,,,,,it did work as well.

you can just make your shell a root shell with the su command

su
vim /mnt/hdb6/boot/grub/menu.lst

I guess knoppix does not have the text editer "nano".

vi

vim is normally pointing to vi so its place in path is vi in debian.

vim /mnt/hdb6/boot/grub/menu.lst,,,,,,,,,,,,,,,,,,,,,,,it did work,,,

nedit /mnt/hdb6/boot/grub/menu.lst,,,,,,,,,,,,,,,,,,,,,,,it did work as well.

Today I realized I can only read the files above,,,I can not modify them,,,what should I do ?

are you root?

is the partition mounted read only?

if yes to the first but no to the second.. chmod +w <filewithpath>

[zillah]

1- are you root?

2- is the partition mounted read only?

3- if yes to the first but no to the second.. chmod +w <filewithpath>

1- Yes I am root ,,,what I did to act as root,,,I typed in: su ,,,,Am I right?

2- How can I check that ?do you mean ls -al ?

3- do you mean I have to change the permission for "chmod +w /mnt/hdb6/boot/grub/menu.lst" or what ever file ?

1. yes, I use su - as the - will give you root enviroment varables.

2. use the mount command

huskeyw usr # mount
/dev/hda3 on / type reiserfs (rw,noatime)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
/dev/hda4 on /home type reiserfs (rw,noatime)
/dev/sda1 on /mnt/maxtor1 type ext2 (rw,nosuid,nodev)
/dev/sda2 on /mnt/maxtor2 type ext3 (rw,nosuid,nodev)
/dev/sda3 on /mnt/maxtor3 type ext3 (rw,nosuid,nodev)
none on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw,devmode=0664,devgid=85)
//192.168.1.209/movies on /mnt/lincs type smbfs (0)

you can see the () behind he mount tell you if it is read readonly readwrite ect

3.yes

[zillah]

use the mount command

The output for this command was not helpful.

What I did:

1- mount /dev/hdb6 /mnt/hdb6

2- Right click on the hdb6 icon (my case).

3- Click on "Actions"

4- Change the read/write permissions to writeable.

Then I was able to modify the file.
