 Posted: Mon May 08, 2006 5:41 am Post subject: Question on mountin FAT32 |
 |
|
Hi,
I have two questions.
1> /dev/hda5 on my hard disk is formatted with W95 FAT 32. Here is how my /etc/fstab looks
/dev/hda5 /mnt/Data vfat users,owner,rw,umask=022,noatime 0 0
Problem is the FAT 32 Filesystem is getting mounted with root permissions and only root can do both read and write. I want all users to have both read and write permissions. Currently users only has read permissions.
Here is how I created the user :
useradd -m -G audio,users,cdrom,games,portage,usb,plugdev,wheel -s /bin/bash sbiswas
passwd sbiswas
2> Second question : I cannot do either reboot or halt from user sbiswas. It says "permission denied". How can I allow sbiswas to issue these commands.
Thanks
Shiladitya |

1:
options are uid=userid and/or gid=groupid in fstab
2:
you can emerge app-admin/sudo and set an alias for init (or reboot, shutdown and so on) |

/dev/sda5 /mnt/xpg vfat auto,rw,users,gid=666,dmask=0007,fmask=007 0 0
First of all create a group for users who may access the vfat drive.
The live above is from my fstab for my vfat drive. Substitute the appropriate group id for users who are allowed to access the vfat drive.

Again create a group for users who can shut down the machine. Add yourself to that group. Change the group for /sbin/halt to the new group created, and give the users of the group execute permission.
Hope that helps.  |

Moved from Installing Gentoo to Other Things Gentoo.
Not an installation problem, so moved here.

|
|
Here's an extract from my /etc/fstab.
| Code: |
/dev/sda1 /mnt/win_c ntfs user 0 0
/dev/sda5 /mnt/win_i vfat user 0 0
/dev/sda6 /mnt/win_j ntfs user 0 0
|
As a normal user I'm unable to read from any of those disks. As root, there don't seem to be any problems.
What am I doing wrong.

Right. Do this as root
#groupadd -g 666 windrives
#nano /etc/group
Add yourself (user account) to the list of users in the newly created group.
Then, change the fstab entries to
| Quote: |
/dev/sda1 /mnt/win_c ntfs ro,users,gid=666,dmask=0007,fmask=007 0 0
/dev/sda5 /mnt/win_i vfat rw,users,gid=666,dmask=0007,fmask=007 0 0
/dev/sda6 /mnt/win_j ntfs ro,users,gid=666,dmask=0007,fmask=007 0 0
|
Then log out.
Log in as the user you added to the new group.
Then as user mount /mnt/win_c or /mnt/win_i or /mnt/win_j
Access the files from the respective locations. |

| It's been a while since i've had a windows install on my PC, but i think i used 'users,umask=000' as my fstab options and it allowed everyone to read and write to the partition. This wasn't a security issue for me because i'm the only one who uses the PC. |

Thanks. That solved it.
On the same topic:
| Code: |
//Scv003/y /mnt/scv003/y smbfs user,umask=000,password="" 0 0
|
How can I make this filesystem read-write to a normal user. Root can both read and write, but a normal user can only read.

Check the permissions on /mnt/scv003/y when the samba share is mounted. They may need to be changed using chmod. Permissions on the PC where the share is located could be an issue too... I've never been very good with samba  |

One little correction.
Change fmask and dmask on the ntfs entries in fstab to 227 and 0227 respectively, so that you don't give anyone permission to write on those even by accident. |
