that's odd. Did you run as root? if so, did it give you any errors or does it just go back to the command line with no output? Please post any output from 'fdisk -l' if there is any.

note: this is a lowercase 'L' not a 1, my font makes it look like a 1 ...could be the problem.

Try

Code:

sudo fdisk -l

and then supply the root password.

Debian disallows login with root and "fdisk -l" is a system-related command requiring root privileges. The above should overcome it.

The above comment applies to Ubuntu, NOT debian.

yeah thought as much. this guy has still not tried to clarify "shows nothing" yet though... path issue or something? maybe he's just not reading it right... i do recall some versions of fdisk require the single /dev entry and only show on a per disk basis. think that was redhat 7.3 i had that on.

Ubuntu is a variant of Debian and inherits much of its security arrangement.

xcore_on · 05-16-2006, 09:57 PM

On debian:
I am use fdisk -l (run as root)!!!
Nothing happen, any erro, any message!!!

so I try this command with othes distribution (Fedora Core 5)
it show information about all disks.

strange not work on debian 3.1r1, kernel 2.4.27-2-386!!!

others ideas?

I don't know a lot about debian releases but 3.1 seems like a pretty small number for a release, is this an older release or something? It's possible the fdisk you have is an out of date version as kewpie suggested. Try listing the device directly:

Code:

#fdisk -l /dev/hda
#fdisk -l /dev/hdb

still nothing? then try

Code:

#fdisk -h

and see what happens (note: '-h' is actually an invalid option, but will list the usage anyways). It seems strange that a command would run without any output whatsoever as this is not very typical for Linux. It makes me wonder if there are deeper issues at work here. If you get any output at all form the above commands, please post.

yes, correct, doesn't mean that whatever you know on ubuntu instantly applies to debian though.

You are right. Debian reacts differently to the sudo command than Ubuntu.

I tried "sudo fdisk -l" on my Ubuntu 5.10 Breezy before putting up my last reply. Tried again and it certainly works OK for me. For Debian I have to do a "su" first.

ok 2 things to try, both can be ran as user:

Code:

df -h

this should give you a list of the partitions and where they are mounted along with the size of each and amount free.

Code:

cat /etc/fstab

will give you a print out of your fstab file that tells Debian were and what everything is. my system looks like this:

Code:

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             5.8G  3.8G  1.7G  70% /
tmpfs                 506M     0  506M   0% /dev/shm

ray@p4ssmahome:~$ cat /etc/fstab 
# /etc/fstab: static file system information.

/dev/sda2       /boot           ext3    defaults        0       2
/dev/sda3       /home           ext3    defaults        0       2
/dev/sdb2       /sharedisk      ext3    defaults        0       2
/dev/sdb1       swap            swap    defaults        0       0
/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0
/dev/hdd        /media/cdrom1   iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
/dev/hdb1       /stuffdisk      ext3    defaults        0       2
/dev/sdc1       /mnt/camera     auto    defaults,user,noauto    0       0
/dev/sdc1       /mnt/USBdrive   auto    user,rw,auto    0       0
/dev/sr0        /dev/dvd        auto    rw,user,auto    0       0

so as you can see it shows all of my IDE and sATA (sd devices) what partition they are on and what they are mounted too.

hope that helps.

do you have sudo setup for your debian box? if not then sudo will not work for you.

Debian Sarge (3.1) is the latest "stable" release of Debian (June 6th, 2005). But Debian is one of the oldest distros around and many distros are based off it.
