Extract ISO (Not mount)

yoachan · 08-29-2010, 11:20 PM

Dear All,

I need to extract some iso files on my Solaris system. The problem is I don't have root permission, and even no permission to mount. So is there anything I can do to extract these iso files without mounting them?

thanks in advanced,

yoachan

I don't think so ... usually a loopback mount is the method (lofiadm), how about extracting the files on your pc then copying across ?

File Roller can open ISO images.

Ouch.... The file has been uploaded hundreds kilometer away....
with my internet speed that will take some time.
It'll be like start all process from the begining.
But if that's the only solution, I guess I have no other option....

AFAIK File Roller is the archive manager of the GNOME desktop environment.
Will it work using command line too? For I can only use ssh console - no GUI.

It works through the CLI:

Code:

file-roller --extract image.iso

However, it still requires a GUI. Can't you "ssh -X" ?

no, really no GUI at all....

A workaround would be to use vnc:

Code:

$ vncserver

You will require a password to access your desktops.

Password:
Password must be at least 6 characters - try again
Password:
Verify:
xauth:  creating new authority file /home/guest/.Xauthority

New 'm3:1 ()' desktop is m3:1

Creating default startup script /tmp/guest/.vnc/xstartup
Starting applications specified in /tmp/guest/.vnc/xstartup
Log file is /tmp/guest/.vnc/m3:1.log


$ DISPLAY=:1 file-roller --extract-here /tmp/image.iso

You can simply use the old dd command to extract an iso from some device:

Code:

dd if=/dev/cdrom of=cdrom.iso

This takes the media at /dev/cdrom and puts it in the file cdrom.iso.

Is this what you were asking for? You can also pipe dd to ssh and directly rip to a network location if you need to.

Isn't VNC needs to be installed first?
As I noted, I really have no root or any power user privilege.
It's only a rented space at web hosting.
If it's possible I want to do it via console for either way I don't have enough bandwidth to do remote GUI.

um..... this machine don't have a /dev/cdrom or anything like optical devices... can't I use any other device?
If /dev/cdrom is exist, don't I have to mount it to somewhere to be able to get what inside the iso file?
In this case I have mount -- which I have no privilege.

The only thing that I need is getting files inside an iso file. no more nor less.

Sure, but it might already be installed. Did you check it wasn't ?

You mean "ssh -X" isn't disabled ?

again, thanks for the reply...

So I need to install an VNC client at my place?
But how can I know that the machine has an VNC server?
GUI really is my second last option for I have a slow internet access.
My last option is copy the iso to my other machine which I have full access, extract them and return extracted files ...

I get this error
(file-roller:24948): Gtk-WARNING **: cannot open display:
even though I've use -x in my ssh command...

Not necessarily as the command I suggested is non interactive.

Trying to run "vncserver" would be a good start. If not in the path, you can search that way:

Code:

pkginfo | grep -i vnc
find / -name Xvnc

How slow ?

I guess this job would already be done should you have started it along with you first posting here, 28 hours ago.

Is there an X server running on your client side ?

kbp · 08-31-2010, 09:12 PM

Please note the case of the 'X' as it means the opposite, you mentioned -

as opposed to what jlliagre typed -

No VNC server.
vncserver: command not found
pkginfo give no vnc result.
find command couldn't find it too.

and 7MB file will take approx an hour....

I've already started it (and still on progress), but with 10GB data, if I'm lucky it will take about a week to complete....
So if there is any other solution, it will finish sooner.

Just read what kbp said, and try it at my GUI machine (I used to use console only) using -X (I've get it wrong with -x).
I get message box saying Archive not supported and at my ssh console

Code:

(file-roller:16258): Gtk-CRITICAL **: file gtkwidget.c: line 5916: assertion `GTK_IS_WIDGET (widget)' failed

(file-roller:16258): GLib-GObject-CRITICAL **: file gobject.c: line 1222: assertion `G_IS_OBJECT (object)' failed

(file-roller:16258): Gtk-CRITICAL **: file gtkwidget.c: line 5916: assertion `GTK_IS_WIDGET (widget)' failed

(file-roller:16258): Gtk-CRITICAL **: file gtkmain.c: line 1231: assertion `main_loops != NULL' failed

As a note, computer that I'm using is a SuSE, not Solaris.

Yes, I got it wrong.
Thanks

Are you sure the image is in ISO format and uncorrupted ?
What says "file image.iso" ?
How did you transfer it ?
