• Is it possible to mount a TrueCrypt volume to a NTFS mount point?

  - by Anthony

  The question is simple really. Under Linux etc.. you can mount TrueCrypt volumes, files or partitions, to any mount point of your choosing whereas in Windows the interface only shows drive letters. I'm wondering if I can mount the volume, a partition in this case, un-encrypted to a NTFS mount point, or folder, instead of using drive letters. The reason I ask is I am running out of letters :(. I'm using Server 2008 with the latest TrueCrypt install. Note: I know how to mount a volume directly to an NTFS folder mount point but doing so, and navigating to the mount point, prompts a notice saying the volume is not formatted - to be expected as the volume is not un-encrypted at this stage.

• Mount drive on remote machine

  - by NikolaiDante

  My current set up is: I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted. Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine. Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy Both machines are Ubuntu 12.04

• How to mount nexus 7 file system to view files from command line

  - by knotech

  Just got a Nexus 7, switched MTP on and plugged it in. It pops right up in nautilus, is titled Nexus 7, and lets me browse all of the files. However, on the command line, it's simply listed as /media/usbdrive and when I try to list the files, nothing comes up. Do I have to manually mount it in order to navigate the files from the command line? And why is it that nautilus recognizes it, and has access immediately, but I can't get at it from the command line?

• Unable to mount 1TB USB external HDD - Error

  - by superbDeveloper

  Hi, I'm getting an error when I plug in my 1TB USB external HDD, the wierd thing about this is that it was working fine before and I've been using it for about a couple of months now. yesterday I compressed one of the folders which had about 120GB of data but the compression failed after an hour and I decided to unmount the drive and shut everything down. Today when I tried to plug in the drive I got the following error: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so output of cat /proc/partitions below muzikayise@muzikayise-supercom:~$ sudo fdisk -l /dev/sdc Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x39dcba64 Device Boot Start End Blocks Id System please will someone kindly assist with this? thanks in advance,

• Cant mount cryptswap1 ?

  - by Jordan March

  From the reading I've done, it seems it's having issues mounting the encrypted files. The guys here: could not mount /dev/mapper/cryptswap1 Seem to be suggesting how to fix it, but I am new to Linux and have NO idea how to do any of that. Can anyone walk me through how to edit that file? Or should I just reinstal? Is there a way to reinstall and keep my programs? I do have separate partitions for boot root home and swap Running Acer Aspire 5750 Intel Core i3 4gb ram Ubuntu 12.10 64bit

• file copy error from system to cifs mount

  - by dwpriest

  When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy locally and between the mount and system via SSH just fine. Any ideas? Thank you

• Can't mount external hard drive

  - by tezza

  i have a problem accessing the data on my external hard drive. I recently did a fresh install but mistakenly left my external hard drive plugged in. When I tried to access the data on the external HDD, it says "no files" but recognizes that there is 290 GiB of data on it. The HDD is 350GB big. I checked the drive with Disk Utility and it showed that the hard drive had a bootable flag. So, in the edit partition, I unchecked this bootablity. Now it won't mount in Ubuntu and now my XP can't recognize it at all, whereas I could access the data on the XP machine before. In disk utility, it doesn't give me the option to check the bootable box in again and I can't access the data on XP either. Any ideas on how to fix it?

• mount remotely mybook live network drive

  - by bob

  I have a mybook live western digital 1TB hard disk connected to fritzbox 7270 router in office. When I am in the office, I can mount this drive to ubuntu since I have added to the etc/fstab file: //192.168.178.30/user /home/user/DISK cifs auto,iocharset=utf8,user=user%password 0 0 Is there a similar, easy & safe way, to do the same when I am out of the office using the static IP of the fritzbox router? I have already added tcp port forwarding in the router for ports 8080 (to 80 of the disk) and 8443 (to 443 of the disk). Thank you in advance

• Cannot mount USB disks due to "not authorized" error

  - by shadovv

  I have Ubuntu 12.04 (.2?) installed. I don't plan to need GUI after setup so I modified the grub to start in console. However, whenever I want to start up GUI I need to type startx. Simple/basic stuff. However I seem to be hitting a snag: I am having trouble mounting/accessing USB flash drives in the GUI I started in the console. "Unable to mount location - not authorized". Seemed like it should be an easy fix, but can't figure out how I'm overlooking it. Can someone help me out?

• Ubuntu Server 13.10 can't mount hard drive that is on my router

  - by Keytachi626

  So I am working currently with my Ubuntu server which I have it on my laptop at the moment so I can test out how to work with the server OS. I have it up and running with samba, openSSH, webmin, and plexmedia server. My problem is that I can't seem to get the server to get to the router hard drive. I have a TP-link wdr3500. The format of the hard drive is a FAT32. What I've tried: install cifs. sudo vi /etc/fstab Type out \\ \tplinklogin.net\volume1 \mnt\media cifs guest 0 0 I have also tried out \\\192.168.0.1\volume1 \mnt\media cifs guest 0 0 But then when I go to terminal and do sudo mount -a, I usually get a error saying wrong fs type, bad option, bad superblock on //ipaddress/dns/volume1 , missing codepage or helper program, or other error. But in dmesg it will say unable to determine destination address. So am I doing something wrong here? I can't install the hard drive on to my laptop since my family is constantly using it to transfer data back and forth on it and they get mad at me if I just take it away.

• Auto-mount filesystems on boot fails (12.10)

  - by Joshua Pruitt

  I have a Compaq HP 8200 slim desktop running 12.10 with encrypted partitions (set up with the text-based installer). Everything's working fine, except... When I boot the computer, my /boot and /boot/efi directories refuse to mount automatically. I'm dropped to the root console, where I must enter 'mountall -v', and everything then continues on just fine. This was happening under 12.04. I've recently upgraded to 12.10, and the problem persists. Except now, in addition to /boot and /boot/efi not mounting, roughly 50% of the time /var will not be auto-mounted as well (and again, 'mountall -v' fixes allows me to boot and move on). I'm puzzled about this one. Running 'fsck' doesn't seem to do anything (the filesystems aren't damaged anyway). What can I try to solve this issue? Here's my /etc/fstab: http://paste.ubuntu.com/1338508/ Thanks in advance!!! Addendum: I have tried changing the entries in fstab from UUIDs to the actual devices, to no avail.

• How to mount private network shares on login?

  - by bainorama

  I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?

• DVD wont mount Ubuntu 12.04

  - by CyborgGold

  I can't seem to be able to mount my optical drive. I have tried numerous solutions from this site with no results. I am not able to see the device inside the file browser either. There is a DVD in the drive. I am running 12.04 on an HP g60-235dx portable. I have a link below to the specs. I will also list what I have tried (that I can find back right now.) I know the drive is functioning, because just before Windows 7 crashed and my MBR went fubar I was watching movies just fine. I am fairly new to linux, so don't assume I know anything. Ok, so here is what I have tried: sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list sudo apt-get --quiet update sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring sudo apt-get --quiet update sudo apt-get install libdvdcss2 dmesg | grep sr0 (no output) apt-get install libdvdnav4 (already installed, and up to date) sudo /usr/share/doc/libdvdread4/install-css.sh ls -l /dev/cdrom /dev/cdrw /dev/dvd /dev/dvdrw /dev/scd0 /dev/sr0 ls: cannot access /dev/scd0: No such file or directory lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrom -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrw -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvd -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvdrw -> sr0 brw-rw----+ 1 root cdrom 11, 0 Sep 10 03:51 /dev/sr0 wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'TSSTcorp' 'CDDVDW TS-L633M' ------------------------------------------------------------------------- sudo lshw optical *-cdrom description: DVD-RAM writer product: CDDVDW TS-L633M vendor: TSSTcorp physical id: 1 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0200 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc sudo lshw | grep cdrom *-cdrom logical name: /dev/cdrom Spec sheet for portable: http://www.cnet.com/laptops/hp-g60-235dx/4507-3121_7-33496192.html If you need any more information than all of that... please let me know.

In the beginning opening and mounting the raid took less than 10 seconds, now (for a few weeks) mounting alone takes 1:30 minutes and the cpu stays around 93% the whole time: The output of "time sudo mount /dev/mapper/8000 /media/8000" is: real 1m31.952s user 0m0.008s sys 1m25.229s At the same time only one line is added to /var/log/syslog: kernel: [ 2240.921381] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null) My Ubuntu-version is "12.04.1 LTS" and no updates are pending. I checked the partition with fsck, but it says that all is ok. The "cryptsetup luksOpen" command only takes a few seconds. I also tried changing the raid-bitmap (as it was suggested in some forum) but it did not change the behaviour. sudo mdadm --grow /dev/md0 -b internal and sudo mdadm --grow /dev/md0 -b none I had the idea that it might be the hardware being slow, but a read test with "sudo hdparm -t /dev/md0" spit out values between 62 and 159 MB/sec: Timing buffered disk reads: 382 MB in 3.00 seconds = 127.14 MB/sec Timing buffered disk reads: 482 MB in 3.02 seconds = 159.62 MB/sec Timing buffered disk reads: 190 MB in 3.03 seconds = 62.65 MB/sec Timing buffered disk reads: 474 MB in 3.02 seconds = 157.12 MB/sec Although I think it is strange that the read rate jumps by more than 100% - could that mean something? The speed test when reading from the mapped (decrypted) device shows similar behavior, although it is of course much slower. "sudo hdparm -t /dev/mapper/8000": Timing buffered disk reads: 56 MB in 3.02 seconds = 18.54 MB/sec Timing buffered disk reads: 122 MB in 3.09 seconds = 39.43 MB/sec Timing buffered disk reads: 134 MB in 3.02 seconds = 44.35 MB/sec The output of a verbose mount "mount -vvv /dev/mapper/8000 /media/8000" does not help much: mount: fstab path: "/etc/fstab" mount: mtab path: "/etc/mtab" mount: lock path: "/etc/mtab~" mount: temp path: "/etc/mtab.tmp" mount: UID: 0 mount: eUID: 0 mount: spec: "/dev/mapper/8000" mount: node: "/media/8000" mount: types: "(null)" mount: opts: "(null)" mount: you didn't specify a filesystem type for /dev/mapper/8000 I will try type ext4 mount: mount(2) syscall: source: "/dev/mapper/8000", target: "/media/8000", filesystemtype: "ext4", mountflags: -1058209792, data: (null) Any idea where I could find additional information on why mounting takes so long, or what additional tests I could run?

• Virtualbox shared folder mount from fstab fails; works once bootup is complete

  - by Ben

  I've got Ubuntu 13.10 installed in Virtualbox 4.3. The host machine is Windows. I have a couple of Virtualbox shared folders being mounted by /etc/fstab. Until recently this setup worked just fine, but after upgrading from Ubuntu 13.04 and Virtualbox 4.2 (at essentially the same time) the fstab mounting stopped working. I get the following error during boot: An error occurred while mounting /home/benme/Documents. keys:Press S to skip mounting or M for manual recovery Pressing M for manual recovery and then trying to mount manually also fails: root@benme-vb:~# cd /home/benme root@benme-vb:/home/benme# mount Documents /sbin/mount.vboxsf: mounting failed with the error: No such device But if I instead skip mounting during boot, wait for Unity to start and then mount manually in a shell, everything works fine: benme-vb ~ % ls Documents benme-vb ~ % sudo mount Documents [sudo] password for benme: benme-vb ~ % ls Documents # actual file list omitted Note that when I mount manually I'm letting mount take all the options from /etc/fstab, and it works. This suggests to me that it's some sort of timing issue, where Virtualbox isn't "ready" to provide the shared file mounts at the point /etc/fstab mounts are run during bootup. Here's the fstab line, just for completeness: Documents /home/benme/Documents vboxsf uid=benme,gid=benme,dmode=774,fmode=664 0 0 Is there something I can do about this from the Ubuntu side? Or does anyone happen to know more about this from the Virtualbox angle? I've found an old report on the Virtualbox bug-tracker with identical symptoms, but in that case the user had updated Virtualbox without updating their guest additions and resolving that fixed the problem; this isn't happening here, I've definitely got the 4.3 guest additions installed.

• In Linux how do I mount a OS-X partition * by name * that is on the same host?

  - by philcolbourn

  I once used gnome-mount like this gnome-mount -o ro -d /dev/sda2 or gnome-mount -o ro -p "Macintosh HD" But, alas, gnome-mount seems to be no more. RIP. I can do this gvfs-mount -d /dev/sda2 (which generates a whole lot of errors but does mount the partition in the /media directory.) This is a related question: http://superuser.com/questions/131918/gnome-mount-alternative-in-ubuntu-10-04-or-how-to-mount-partition-with-normal-use But how do you do it by name?

• permanent NAS-mount in Ubuntu - wrong fs type, bad option, bad superblock

  - by Emil

  My network drive shows up in the file browser, just like my external usb-harddrive. Moving, running and editing files works. Hovering over it shows smb://lacie-2big/nasdisk . BUT, when I want to save a file, the drive doesn't come up as an option. All I can see is my other places, including my usb-harddrive. I am a complete newbie but I am GUESSING that it has something to do with the mount not being a "real" mount but just a shortcut to the smb location. So I ran the tutorial at https://wiki.ubuntu.com/MountWindowsSharesPermanently about how to "mount a network drive permanently". edited my fstab to //LaCie-2big/nasdisk /media/nasmount cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0 and running sudo mount -a gave me the following error: mount: wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program) In some cases useful info is found in syslog - try dmesg | tail or so Now thats a very helpful error message, BUT, before I go any further, I'd be really thankful if one of you could tell me if I'm even in the right ballpark, or if my actual need: to be able to download files (ie torrents) directly to the drive, can be possible as it is already. Question: How to fix "wrong fs type, bad option, bad superblock on //LaCie-2big/nasdisk, missing codepage or helper program" when running mount -a
