linux file locks

[Nightmare-Rex]

so ok i dont know BEST way to explain this. but in linux mint 7 (very old version) i can boot up to nearly any computer. and delete, modify any file without having to go thugh the horur wait of giving "permissions" on windows, or able to delete a bad virus that cant be deleted when widnows is running. boot linux mint 7, fidn the offending file edit or destroy it.

 

NOW however with like lkinux mint (and all linux) mint ubuntu eta above liek mint 8 or 9 there is a LOCK on the files and says "don't have permission" tyo do that, and read need "root access" to be able to do ANYTHIGN to the file (s) but the onyl way  to get "root access" is to INSTALL the lunux! but i DONT WANT TO INSTALL i want to use the temp linux to modify or delete offending riles, or delete a windows.old without waiting triple time for wondows to giv e"permission" to delete it. HOW CAN I REMOVE the dang lock on a newer linux and be able to easily do it as if i woulddo in linux mint 7?

 

hope i explained it good enugh to show exactly WAHT i  am talkign about.

Have you tried using sudo rm filename in the command line? That should delete things if you were a root user. However if you are just using temp linux why can't you just keep using mint 7?

The live linux instal doesn’t let you use root? It should… try Su root? 

[Nightmare-Rex]

i mean i coudl keep using mint 7 but eventualy will HAVE to update since less BIOS and more UFEI. and yea i tried doing sudo su    when i find my newer linux i will try the sudo rm but reads omewhere that haden tworked, why do they have to make it difficult? idiots brickign their computers?

yes i tried it and no dice.

Try disabling Windows Fast Startup and see if solves your permission issue. When enabled and detected, the Linux NTFS implementation will "lock" the drive for safety reasons, requiring root access to modify it.

no its nothing in windows that has to do with it, sinced i tested linux 7 on a computer the SAME computer with linux 12 and 13 i think? but 7 works and 12 has locks so it IS somehting IN LINUX not windows.

[Nightmare-Rex]

im still intrtested learnign more about linux and hhow to remove the lock and why this happens in newer versions but not older versions (bump) if peaople here don't know much about linux anywhere to point me to to learn more?

if this is referencing the windows systems you talk about, I think it would be related to BitLocker on windows preventing access.

if this is referencing Linux systems you talk about I think that would be because Mint 7 doesnt have the ability to de-crypt encrypted hard drives/ partitions of the newer linux.

 

if it is the system that is to new it could be related to the secure boot or tpm module in bios/uefi. (may need these settings turned off, while you work on the system)

 

however linux mint 20 - 20.3 should be able to help with some of those issues.

https://wiki.archlinux.org/title/NTFS-3G#Metadata_kept_in_Windows_cache,_refused_to_mount

 

 

It's possible in older version they were forcing the mount as "rw", https://blog.arvixe.com/how-to-force-mount-unclean-shutdowned-windows-ntfs-or-fat32-drive-in-linux/

Which has since been deprecated, https://linux.die.net/man/8/ntfs-3g

force
This option is obsolete. It has been superseded by the recover and norecover options.

recover
    Recover and try to mount a partition which was not unmounted properly by Windows. The Windows logfile is cleared, which may cause inconsistencies. Currently this is the default option. 

norecover
    Do not try to mount a partition which was not unmounted properly by Windows. 

or there wasn't a check in place, but as of now it is part of the ntfs-3g driver implementation as it should be.

 

For Permissions

https://linux.die.net/man/8/ntfs-3g

Access Handling and Security

By default, files and directories are owned by the effective user and group of the mounting process, and everybody has full read, write, execution and directory browsing permissions

 

https://wiki.archlinux.org/title/NTFS-3G#Default_settings

Default settings

if the parent folder that it is mounted upon has the proper user or group permissions (e.g. /run/media/<username>/), then that user or group will be able to read and write on that partition(s).

so saying it just cant be done? why was that done? why dose linux have to "respect" windows file ownership and make wait hours for that crap to prcess isntead just being able to quickly delete shouldent we have a choice so can delete viruse, or hell evne if did want to delete our windows we should be allowed to :/.

 

but yea cannot write or delete files that were made in windows on new linux but can on new linux, i also am still learnign all that linux jargon since maily use it for deltign viruses eta.

Nightmare-Rex, this actually does not sound to me like it has anything to do with the OS's per-say, but moreso with the permission bit set on the filesystem (whatever that filesystem is) or the manner it was mounted.

I think you need to get off the live distro and do it for real if you are unable to obtain root. As people have mentioned it should be as simple as using sudo. Most live distro's are not intended for daily use.

Try the distro name or blank as a password for sudo. Also be careful.. the root user can kill your box so there may be a good reason you can't edit what you are trying to edit. Linux and Unix won't stop root from deleting the box. Windows files on NTFS may be mounted as read-only also because it's a foreign filesystem, it can be mounted read-write but again, know what you are doing.. Live distro's sometimes do that to prevent new inexperienced users from causing accidents on the OS that is installed on the system. Nobody wants to read: "I tried the live CD and now windows won't boot" so it mounts it read only.

To remount it you'll need sudo working.
 

# Use lsblk and the mount command to find the device and mount point. ro means read only.
lsblk
mount | grep -i NTFS

# Once you know the device path and mount point remount read write with.
sudo mount -o remount,rw /device/path /mount/point

To prevent data loss.

 it can still be manually mounted in Linux with "rw".

• Find the disk and partition
  • fdisk -l

• Remove the Windows Metadata that is used for Fast Boot

• • ntfsfix /dev/PART_TO_MOUNT

• Make sure you have a directory to mount it in that you have full permissions on.

• • mkdir /mnt/windows

  • chown $USER:$USER -R /mnt/windows

• Mount the partition

• • mount /dev/PART_TO_MOUNT /mnt/windows

alrigh tsorry for beign such a noob with linux, but i mean its allready mounted when access it? so hav eto unmount it since its like just -R mount and have to switch it to -RW? i need to possibly buy antoehr stick, its a pain need one under 8GB for bootign certain computers but meany 8GB same price as a 32GB.

 

and wahts the widnows metadata? is that the secuity permissiosn thing? i read spooem thign about iwndows 10 and 11 put soemthiogn on fiesl to show where it was made what computer and when eta, (dotn really liek the idea of that) so if change computer it will edit this wired unseen data? dose windows 8.1 and windows 7 do the same thing?

[10leej]

Linux Mint and Ubuntu hard disable root login by default so you need to use sudo

 

sudo su

now to set permissions you use chmod (a=all,plus ReadWrite)

chmod a+rw -R filename

You might be dealing with two separate things.

The filesystem is mounted read only: In this case, not even root can change permission until it's remounted RW.
The files are marked RO by the OS: in this case root (sudo) can change the permission.

I don't think anyone really knows so this is why you are getting different advice here from different ppl.

i KNOW its not that the files can tb emodified as linux mint 7 and BELOW lets me, its above 8 that gives me problems. i tried what was sied eailer and it ask me for a password so still cant get root on live 8+ LM (trying v20 atm)

allright so i have to do it before boot or something?since when try sudo su on the LIVE "cd" it ask for password. so i assume theres some sort of default password for LM 8+m jus tupdated the mint to latest now 20.4 doing that i still cannot delete or modify files on hardrive thugh evne thugh this time diddent ask for password.

[C2dan88]

Linux mint has no password for root account.

Typing sudo su should change the terminal prompt to this without asking for password

root@mint:/home/mint#

Indicating your now running the commands as root user

 

To ensure the windows drive is being mounted with read/write permissions. Mount the windows drive and then open terminal and run findmnt command.

This will list all mounted volumes. Find your windows drive in the list.

• fstype column should be listed as ntfs or fuseblk
• options column should list rw as a mount option.

With these options you should be be able to create/modify/delete files on the windows drive without any permission issue.

 

What files in particular are you trying to delete? Most windows system files (such as windows.old) can be deleted using Windows disk clean-up when run as administrator

The username for the live session is mint. If asked for a password press Enter.

The NTFS driver was moved "in-kernel" at some point, and the funky bits merged with ntfsprogs.

The biggest shift in the paradigm between 2.6 and modern linux is live-distro devs treating users like idiots and not giving them root access by default, because reasons.

There was also a shift from ntfs-3g to ntfs3 drivers between 5.14 and 5.15; ntfs3 is a fully fledged filesystem driver with NTFS POSIX ACL's which will may/may not help you.

 

Anyway, there are only 2 things you need to do

• Make yourself root (with 'sudo su' or 'sudo <command>' or just plain 'su')
• Issue this command 'mount -a -o remount,rw'

If you can learn to do this in a non-gui console, along with the linux way to navigate files/file systems (cd, rm,  mv, nano/vi, tab completion, \ to escape spaces etc), it'll speed up your process a lot, and give you access to a much wider range of "Live OS's" to choose from like these.
