[SOLVED]Bad file descriptor in Veracrypt.

claudiogc · 2017-09-25 21:02:22

Hi!

I'm trying to create a 2GB NTFS encrypted volume but when he ask me to enter the user or admin pass, after I click in Format(and get 100% format done), I get the following error message:

Bad file descriptor
VeraCrypt::CoreService::StartElevated:517

And then i get back to the previous screen, the Volume Format screen.

I'm running Veracrypt as user. I tried both user and admin pass and didn't work. I added this line in my visudo I don't know if this information is helpful for you: "claudio ALL=(ALL) ALL".

How can i fix that?

Please see this thread:

https://sourceforge.net/p/veracrypt/dis … /f8dbb975/

Does that resolve the issue?

...also, please consider removing that line from your "sudoers" file! Especially if you don't need it, or if you don't know what it does...

EDIT: I copied the relevant information here, for reference:

The error was due to Linux not being able to find the localhost machine name. It was fixed by modifying "/etc/hosts".

So, i've read that before create this thread. The problem is I don't know what to change in there.
Here the content of /etc/hosts.

#
# /etc/hosts: static lookup table for host names
#
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost
::1 localhost.localdomain localhost
# End of file

please consider removing that line from your "sudoers" file! Especially if you don't need it, or if you don't know what it does

I want to give all su permitions to my user. Only I use this notebook.

What is the name of your computer, in "/etc/hostname"? If my computer was named "scoobydoo" then I would make this change:

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>	<hostname.domain.org>	<hostname>
127.0.0.1	localhost.localdomain	localhost	scoobydoo
::1		localhost.localdomain	localhost	scoobydoo

# End of file

Does that allow you to use VeraCrypt?

Unfortunately did'nt work.
I've read an interesting thing here:

http://veracrypt2.rssing.com/chan-19067 … _p202.html

This happens only when I call veracrypt as a normal user and Veracrypt asks through graphical sudo for a password. When this happens, there appear two sudo processes. When it displays mentioned error, one process is shown as defunct. AFter I click OK, both processes disappear. When I run veracrypt with sudo before the actual command, there is no problem. Another thing I discovered is, that this happens whenever you start a new terminal session, so it is not true that it happens only first time after starting up the computer.

So, started it with sudo and it worked fine! Then i installed gksu and tried to run it through gksu and worked fine too.

I would like to know if is there any security problem running Veracrypt through gksu because I read I shouldn't start GUI programs as super user.
