Ubuntu :: User Doesnt Have Write Permissions To Floppy?
Jan 7, 2010
so i have a limited user (my dad) on Jaunty who has no write access to his floppy disks. Nautilus gives a permission denied error, and i discovered that root owns the floppy drive, thus allowing his read-only. (that write tab on the floppy in on btw). However, when i login as a admin, nautilus says that user has write access. ??? I check the user's user privliges and everything exept "administer the system" is checked. I can copy files on it by logging in as root.

I have a computer with no floppy drive (x64 ubuntu lucid installed) I have a program (wine windows xp) that will only save data and export data from/to a floppy drive. I found information on setting up an emulated floppy drive. i.e.
sudo dd bs=512 count=2880 if=/dev/zero of=imagefile.img
sudo mkfs.msdos imagefile.img
sudo mount imagefile.img /media/floppy -o loop
I modified the winecfg to include under the drive section A: /media/floppy. Problem is I cannot write to the drive as a normal user. I have tried everything I know but only root can read write to the drive. Is there someway to set up this emulated floppy to allow me as a user to write and read contents.

I want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.

I have recently installed linux 'uberstudent'and find it doesnt recognise my floppy drive but more importantly I cant install my printer a samsung ML4500 laser. There are readme files (reproduced below) but I just dont know enough about the system to know what to do with them " does it mean anything to anyone ? I am a bit reluctant to experiment with terminal incase I mess up the entire system ! also could their be a connection between this and the floppy not working ?
1.AUTORUN will not run
2.clicking cdsetup.exe and selecting 'open with archive manager' results in : 'an error occured while loading the archive'
3.clicking cdsetup.exe and selecting 'open with wine windows programe loader' results in 'samsung printer setup window'etc, and it appears to load normally until 'PROGRAM ERROR 'DAC1.EXE encountered problems and has to be closed.
4. Inside the linux folder are three file's, copied and shown below
The first file is entitled :

I currently discovered a problem when using the floppy drive /dev/fd0: I can't use it. I can mount /dev/fd0 as normal, can create/write a file, but it is not written to the floppy disk. Instead of that the current program (eg vim) hangs (or is "uninterruptable") until I remove the floppy disk from the drive. Because of the removal I get several errors in /var/log/messages. What I'm doing:
== snip ==
mount /dev/fd0 /mnt
echo "TEST" > /mnt/test
sync [--> HANG until I remove the floppy disk]
[sync "completes"/terminates, insert floppy disk]
umount /mnt
== snap ==
(In this example I used echo instead of vim, because it behaves the same in this situation) The errors I get are as follows:

OS: Windows XP
Virtual Machine: Bochs-2.4.5
I want to learn some details about linux booting, so I begin writing a small boot program myself. Yesterday, I was writing a small boot program and planned to use it boot a Bochs virtual machine. The boot program is written in assembly language and compiled with nasm.I use bxiamge.exe in Bochs and create an floppy image called boot.img and configure the Bochs virtual host to boot from this floppy image. My question is how to write the compiled boot.bin program into the floppy image(boot.img)?

There are lots of tutorials and opinions on file permissions and web hosting.
So lets say I wanted to allow write permissions to the /var/www folder.
which would be best practice?
Chown -R user... allow a specific user to have write capabailities.
use gksudo nautilus (unsure what this does)
or open the folder to all parties.
If anyone has any opinions on file permissions in general or web hosting security then feel free to throw them at me.

I've looked everywhere but I can't find where to change the default box for incoming mail, or am I on the wrong track. It's a nuisance having to change folders and I can't configure wastebin to empty on exit.And I can't get kmail to import from evolution. Do I have to go to the evolution storage and do it manually, and if so, how do I do that?

Is there something weird about the FLOPPY DRIVE on F12? Nothing associated with it works & I can't get an icon for it. Also the FLOPPY FORMATTER no longer works. (mine is an internal drive)- I had some really miner quirks with it in 10 but it worked. I had some workaround launchers that I used until an upgrade semi-fixed it. (It would give a false error that it couldn't run but did. I just ignored it.)
I tried to edit FSTAB to cure a problem of my BACKUP drive showing up twice*** so while I was in there I added the stuff for the floppy & it still doesn't work. If I try to mount it manually, I get the error that /dev/fd0 doesn't exist.I tried to find some info on it & it SEEMS that there MAY be a bug but I'm not sure as the info is a bit confusing as to just what version & such they are talking about. And there was also the problem that all the stuff seemed to be OLD or not related to my problem.I why I quite hacking at my system, is that all my workaround launchers & the formatter say that there are GNOME things missing & they can't run. So I figure that there is something missing or screwy already & that I'd better ask BEFORE I make things worse or actually break something.With the fact that floppies are about gone, it's getting to be not that big of a deal but I still find myself having to use them for repair purposes (albeit, not as much) & it gets to be a bit of a pain to fire up M$ just to do something like this.
*** It appears that the one in FSTAB was the one I needed, so where would the OTHER one be so I can get rid of it? Or at least make it auto mount.

I am having a Promise TX4650 RAID controller & trying to create a driver floppy for installing the drivers. Also am using RHEL 5, I can create the driver floppy, but when I type "mount /dev/fd0 /media/floppy" I get error: "mount: mount point /media/floppy does not exist".Can I get the files in a format other than the ext2 floppy image, so that we do not need to use a floppy drive?There is a readme file inside the driver archive & you can use that as a reference.

From a Win 7 client, I can copy/create/delete any files on any share on the Ubuntu Samba server so long that is part of my nix file system which is all ext4.This box also has and NTFS partition on it primarily for storage. I can copy/create/delete anything on this partition form the same Win 7 client with the exception of Quickbook save files.I have scoured the web looking for anything close to this but have yet to find anything that looks similar. Not lloking for a direct answer but if there is anyone else that has issues copying specific types of files to a Samba NTFS partition.

I am running Karmic x64 on a HP laptop that has a cd/dvd burner. I have a r/w cd with files on it and I wish to add/remove files to it. After it mounts automatically on insertion, I unmount it and remount with:
sudo mount /dev/sr0 -t iso9660 -w /media/cdrom
(I tried assorted other hare-brained things also) but it always says that the filesystem is read only. Do I need to use a different device than sr0? Is it even possible under Ubuntu?

I'm pretty new to Linux but I know my way around. I've gotten Google Earth downloaded and am trying to install it. Everything is fine until I try to install it into /usr/local (or somewhere in there). The Google Earth Setup keeps telling me that I do not have write permissions on this directory. Question: How do I change the write permissions for this folder? Or should I install the program somewhere else? The last program I installed (xMind) installed into /usr/local.I am the only user (administrator

I have apache2 running on my computer. I want to change the permissions for /var/www/ so that I can edit the files without a problem. Right now I can use the gksudo command, but I'd like to be able to have all the files available when using an IDE like eclipse.
I've read in several places that
Code:
chmod 755 /var/www
will do, but if I'm not mistaken that would give read/write access to anyone. I'm not in a production environment, so I'm not too worried about security, but I'd like to give anyone else as less permissions as possible. Would this be possible?

Just finished downloading a game in .run format, i downloaded it to my Home>Downloads folder and ran these commands in terminal: (game is tremulous if it matters)
chmod +x tremulous.run
./tremulous.run
It started it up in the terminal and i began working my way through the installation process, and i tried to install it into my Home>Games folder. (Is it supposed to be home>games or your username>games?)
and it said PERMISSION DENIED. No write permission to Home/Games/
How do i give myself read and write permissions to my game folder?

I'm trying to set up sshfs on a desktop/fileserver so that I can mount its HDD's I use for storage on my laptops. My issue seems to be getting permission to write to the mounted drives. I just keep getting permission denied. here is what I think are some relevant tidbits.
mount point on server,
Code:
joe@joe-desktop:~$ ls -ld ~/sda2
drwxr-xr-x 2 root root 16384 1969-12-31 19:00 /home/joe/sda2
HDD I'm trying to mount
Code:
joe@joe-desktop:~$ ls -ld /dev/sda2
brwxrwxrwx 1 joe disk 8, 2 2010-10-17 15:22 /dev/sda2
Mount point on client
Code:
joe@joe-laptop:~$ ls -ld ~/sda2
drwxrwxrwx 2 joe joe 4096 2010-10-17 19:58 /home/joe/sda2
This is the command I'm trying to use to mount
Code:
sshfs joe@192.168.1.103:/home/joe/sda2 ~/sda2
I can chmod the mount on the server to 777 but as soon as I mount the HDD to the server all write permission just goes *poof* and its back to "drwxr-xr-x".Chown seems either, it just wont stick.

I have a file server running 10.04. I have a user that belongs to 2 groups (users is the primary and IT is the secondary). I have permissions set up so that this user and other users that belong to the IT groups can read/write files and others have no permissions whatsoever. I have also set the umask to 0007 so that any files created have the effective permissions. My concern is this: since my primary group is users, is it possible for me to create files with the owner group IT for only this specific folder?

I have a Natty headless server that I would like to set up shared directories and grant specific users write permissions. I use a Windows 2008 R2 machine with Active Directory for authentication and have created a group GroupWithWriteAccess which I want to have write access to the shared directory. I want all other users to have read only access. I have edited my smb.conf file with the following
Code:
[TV]
path = /media/share/Media/TV
writeable = yes
write list = primaryuser @GroupWithWriteAccess
create mode = 0660
directory mode = 0770
The machine is fully setup to work with Windows authentication and I can access shares from the ubuntu machine, it's just sharing local directories with the correct permissions that I can't work out. So far I can access the files from my other machine, but I do not have write access even though I am logged on as a user who is a member of GroupWithWriteAccess.
