I am trying to mount a host directory in Docker, but then I cannot access it from within the container, even if the access permissions look good.

I am doing

    sudo docker run -i -v /data1/Downloads:/Downloads ubuntu bash

and then

    ls -al

It gives me:

    total 8892
    drwxr-xr-x.  23 root root    4096 Jun 18 14:34 .
    drwxr-xr-x.  23 root root    4096 Jun 18 14:34 ..
    -rwxr-xr-x.   1 root root       0 Jun 18 14:34 .dockerenv

    drwxr-xr-x.   2 root root    4096 Apr 19  2012 home

and a lot more lines like that (I think this is the relevant portion).

If I do

    cd /Downloads
    ls

the result is

    ls: cannot open directory .: Permission denied

The host is Fedora 20, with Docker 1.0.0 and go1.2.2.

What is going wrong?

I know how to use rpm to list the contents of a package (`rpm -qpil package.rpm`). However, this requires knowing the location of the .rpm file on the filesystem. A more elegant solution would be to use the package manager, which in my case is YUM. How can YUM be used to achieve this?

All of the sudden I&#39;ve been having problems with my application that I&#39;ve never had before.  I decided to check the Apache&#39;s error log, and I found an error message saying &quot;zend_mm_heap corrupted&quot;.  What does this mean.

OS: Fedora Core 8
Apache: 2.2.9
PHP: 5.2.6

What does &quot;zend_mm_heap corrupted&quot; mean

    sudo find /etc | xargs grep -i fedora &gt; searchFedora

gives:

    /etc/netplug.d/netplug: # At least on Fedora Core 1
    ...

But see the Fedora version in the `/etc/netplug.d/netplug` file. Is it serious?

How can I find the version of the Fedora I use?

I have just installed Apache 2.2.17, and I am using it first time. 

Now when I try to start the server using the command `service httpd start` it gives me the message:

&gt; httpd: Could not reliably determine the server&#39;s fully qualified domain name, using ::1 for ServerName

Now I think I have to set ServerName and the IP address as I search through Google. But I don&#39;t know in which file I have to set.

How can I fix this problem?

I installed mysql through yum just now and the OS fedora installed mariadb for me.
I know mariadb is a new branch of mysql, but I can&#39;t understand why it does not ask me for setting the password.
I have tried for 123456 and so on, but I failed. 
My fedora is new, and this is the first time to install mysql/mariadb.
What should I do for it?

What&#39;s the default password of mariadb on fedora?

That&#39;s much the question. I have PHP 5.2.9 on Apache and I cannot upgrade PHP. Is there a way for me to enable SOAP in PHP 5.2.9? The PHP manual did not help at all when it said, &quot;To enable SOAP support, configure PHP with --enable-soap .&quot;  How do I configure? 

How do I enable --enable-soap in php on linux?

when I try to load a web page to terminal it gives `curl: (6) Could not resolve host` error. 

I have internet in my PC and trying from my home internet connection. So as I there is no any proxy involve here. 

    [root@localhost kevin]# curl http://google.com
    curl: (6) Could not resolve host: google.com; Name or service not known


`clean all` and tried again but no lucky. 

But if I use IP instead of the domain name, it works fine. 

`[root@localhost kevin]# curl http://173.194.46.0`

any clue please?

I have upgraded Fedora from 28 to the latest 29 and Slack doesn&#39;t work anymore. It returns a `Segmentation fault (core dumped)`.

Edit: The issue has been fixed on Slack 3.3.4

I want to list all packages I have installed on a system from a given repo using yum. Usually to do this I use `yum list installed | grep &quot;something&quot;`. But now I am faced with a problem. The repo I am interested in does not have that &quot;something&quot; for me to grep. The packages from that repo do not have any distinctive characteristics. How do I list them? 

I looked through yum man pages but did not find anything. I wonder if there are other commands I could use.

I want to view the unallocated free space on my hard disk through terminal.
I&#39;ve burned my brains searching the internet for a possible solution, but all in vain.

I used all sorts of commands like `df`, `du`, `fdisk`, `parted`, etc.
It tells me about the disks that are mounted and unmounted, but what about the unallocated space that I&#39;ve left free?

Of course I can view it using the &#39;Disk Utility&#39; app provided by Fedora, but since I LOVE being in the terminal I&#39;d like to view in it.

Can anyone please help me with a solution?
