Eth0:no IPv6 Routers Present

I can't seem to mount a CD-R or DVD-R, doesn't matter if it is blank or not.
However, when I use a program such as Brasero, I am able to write to them. I cannot use dd to write to them.

This is the output of trying to mount/unmount.
Code:

root@delarocha-> mount /dev/sr0 /media/cd
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so.

root@delarocha-> umount /dev/sr0
umount: /dev/sr0: not mounted
root@delarocha-> umount /media/cd
umount: /media/cd: not mounted
root@delarocha-> umount /media/cdrom
umount: /media/cdrom: not mounted

dmesg | tail
Code:

root@delarocha-> dmesg | tail

[ 1536.299846] end_request: I/O error, dev sr0, sector 0
[ 1536.299915] EXT4-fs (sr0): unable to read superblock

I don't think it can be anything wrong with the disk, since it is a untouched disk.
Note: The results of everything(apart from dmesg I would assume), are the same for a CD-R and DVD-R

This is what I get while trying to dd a .iso and .mp4, respectively.

Code:

web@delarocha-> dd if=/dev/sr0 of=~/Downloads/xubuntu-14.04.1-desktop-amd64.iso
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000377316 s, 0.0 kB/s

Code:

0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000377179 s, 0.0 kB/s

uname -a
Code:

Linux delarocha 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt2-1 (2014-12-08) x86_64 GNU/Linux

When I used lsblk when I close the disk tray, it shows it mounted.
Code:

sr0                     11:0    1     2K  0 rom

But after I use the dd command to write the .iso, it disappears.

Here is my /etc/fstab
Code:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#

/dev/sdb1       /media/usb0     auto    rw,user,noauto  0       0

I have also tried replacing /dev/sr0 in the above commands with /media/cdrom0.

Dear All,

I am using OLE 6.2, 32 bit. Today I was trying to open the other drives (windows C drive and external drive both are ntfs), when I tried to open it, I go the following error

Error mounting: mount: unknown filesystem type 'ntfs'

Please advise how can I fix it, I did a google search but since I am new I am unable to understand what I should really do. Sept by Sept advise would be of great help.

Thanks in advance.

Did you find any way to get out with this error ? I've got the same with an extended partition...
Code:

I have a dual boot laptop with debian stable & Windows 7.

The HD partitions a
sda1: NTFS for W7
sda2: FAT32 (currently unused)
sda3: linux /boot
sda4: linux ext4, which is LVM with encryption

I've re-installed W7 and now need to recover the MBR & grub menu.

I've booted with the netinst usb in rescue mode, but it fails to mount the root partition /sda4:
"An error occured while mounting the device you entered for your root file system (/dev/sda4) on /target"

and /var/syslog shows:
Code:

rescue-mode: selected root device '/dev/sda4'
umount: cant umount /target: Invalid argument
isofs_fill_super: bread failed, dev=sda4, iso_blknum=16, block=32
EXT2-fs (sda4): error: unable to readsuperblock
EXT3-fs (sda4): error: unable to readsuperblock
rescue: mount: mounting /dev/sda4 on /target failed: Invalid argument

So it seems like something is wrong with the mount command?

Would appreciate suggestions how to solve this.

Thanks

Hello,
I just want to know if it is possible to mount a share to /tmp on RHEL 6.6?

For example to mount <device hosting share>:/vol/share_name as /tmp
which is already mounted as follows:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/SDVol-LVtmp
1998672 512380 1381436 28% /tmp

Thank you.

mount -t cifs //192.168.86.135/home/ /smbdata/ -o ussername=localhost.localdomain/smbuser,password=x
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)


192.168.86.135 is my primary server IP and i tried to mount from another server which is accessible

Please help

Greetings All,

I'm NEW to Linux 13.10. I'm getting a error message on start up.
In the past, I would just press S to skip mounting. That is NOT
working any more.

Error Message : An error occurred while mounting/mnt/3F3C-1AF6.
Press S to skip mounting or M for manual recovery

Is there a command, that I can use to continue to boot or at
least find out what is wrong with my Ubuntu 13.10?
When I press S or M .... nothing happens.

Thanks in advance!

PEACE to ALL .... MJ

Hi all. I can't connect to my Win 8.1 box from Linux Mint. I can ping the Win box successfully. I can access my Linux share from my Win box. It seems like the problem is with windows. I've been working on this problem for about three days now with no luck. I've uninstalled Norton Security in my Win box. I've deactivated Microsoft's firewall. Not helping. My smb.conf is:

[homes]
read only = no
security = domain
workgroup = WORKGROUP

[share]
comment = Shared Data
path = /home/gary/share
gues ok = yes
writeable = no
browseable = yes

To make things simple i created only one shared folder on my Win box, asm. On Linux i type: sudo mount.cifs //GARYZ97/asm /home/gary/share -o user=Gary ; Gary is apparently my correct Windows username. BTW, i've also tried gary.
Linux responds with: [sudo] password for gary: jj ; this is my correct sudo password
Next response is: Password for Gary@//GARYZ97/asm: ; here i have tried my Microsoft Account password; i've tried just hitting enter; i've tried jj my Linux password. I'm at my wits end. What am i doing wrong? I've googled so many different sites but no one seems to have the problem i have. Please help. I don't want to pull out all my hair. I can access my Linux share from Windows, edit it, save it, and i see the changes on my Linux box. I know i'm being repetitive here but i just can't access my Windows share from Linux. I have run testparm on smb.conf and no problems there. Almost forgot. After entering what i believe is my correct Windows password i get: mount error(115): Operation now in progress, and then on the next line, Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Hello everyone,

I just tried upgrading to Linux Mint 17 from version 16, and I obviously did something wrong since when I'm prompted for my password, I get an error message saying "failed to load session cinnamon."

Then there are some error logs which say failed to connect to virtual box kernel service for several lines, then below that "unable to find cinnamon-fullback-mount-helper."

I tried doing ctrl alt f2, but I get a whole bunch of gobbledy gook which I'm unable to copy and paste.

I also tried burning a new DVD-R with Mint 17, but my computer doesn't even read it when I power it on. Otherwise, I would have tried reinstalling the OS.

So any suggestions you have will be greatly appreciated.

Thanks.

Hi,

I have problems mounting my second drive at boot automatically.
(sorry i am a noob)

When i use the mount command, it works fine.
Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

But when i try to add one if the following lines to /etc/fstab
It will not mount the drive at boot or with Code:

mount -a

, also fstab is empty afer reboot (normal??)

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults,errors=remount-ro 0 1

Code:

UUID=553afede-fa45-4cdc-9972-c0a9aa899509 /mnt/HD/HD_b2 ext3 errors=remount-ro 0 1

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults 0 1

output blkid:

sysfs /mnt/HD/HD_a2/squeeze/sys sysfs rw,relatime 0 0
proc /mnt/HD/HD_a2/squeeze/proc proc rw,relatime 0 0

When mount command is used Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

The following line is added to mstab -->
Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

I diont know what i am doing wrong, mount for HD_a2 works fine (other disk, worked at default), i hav e NAS DNS-325 where i installed Debian on. I used this tutorial to install debian.

The strange thing is, i had to reinstall my NAS, and befor it worked fine after i had installed debian 2 years ago, i just dont remeber how i fixed this.
