So, I have been reading about this for a long time and there's never a conclusive answer to be found anywhere.

I have a Centos 6 LAMP web server which mostly hosts websites created by yours truly and the occasional website created by someone else.

Which is the most secure way to configure Wordpress folders ownership AND keep all the automatic features (updating, uploading and so on) without the need to insert ftp or sftp credentials each time?

Aside from permissions (which I always set to 755 for folder, 644 for files and 600 for special files, as suggested everywhere), there's a lot of different ideas about ownership.

Somebody says apache should be the owner of the whole folder. Somebody says that the owner should be your server user (root for instance, or a dedicated user) and never apache.

But if the owner is not apache, you have to use your ftp credentials to upload, update and so on.

So is there a way to actually have it all? What's the safest and smartest way to configure ownership for Wordpress?

Thanks guys.

We have a kiosk running Android with a keyboard and mouse. Trying to reinstall the OS but there is no SDcard slot just USB but it wont boot off any usb drives (tried linux and android installers). Don't know they shortcut key to get it to boot off usb. Its not a phone so there is no 'power and volume down' combos. (See pics).
 It boots and displays the kitkat 4.4.2 logo and version then goes black...then screen freezes on black. There are no model numbers listed anywhere on the board.

Ubuntu freezes and shuts down laptop when writing to c drive.

this same command runs fine on one laptop but crashes on another....

Hi there, I need some help with creating a folder structure in Artifactory which is installed on an ECS cluster within an redhat server ec2 instance.this is my first time doing this and I have been a bash script file which creates the necessary folders...my question is,how do I make sure I run this bash script file correctly and how do I check afterwards that it has been successful created using the web UI or command line... thanks in advance for your help.

While setting up a PXE boot server on a CentOS 7 machine, I encountered a strange problem with TFTP. I cannot retrieve any files from the TFTP server without encountering a timeout problem. The boot process comes so far that I correctly get an IP address and a file name from the DHCP server. However, when the boot files are to be retrieved from the TFTP server, a "TFTP open timeout" message comes. If I manually make a TFTP connection to the PXE server from a local computer, I immediately get access to the server. But if I try with a "get pxelinux.0" command, I get another timeout message.
My firewall is set up correctly and it also makes no difference if I completely turn off the firewall. SeLinux is also disabled.
If I make a tcpdump on port 69 I get the following message:

I have a C# program that runs perfectly under Windows 10.  It uses Connected Services so that I can add in additional Class and Method functions to connect to Ultimate Software's HR system and pull our employee information from.  What I would like to do is run this application under Linux CentOS.  I installed Mono for Linux on both CentOS 6 and CentOS 7; and verified 100% that it can and does run compiled Visual Studio C# programs under Linux.  No problem.

However, when I run the EXE program under Linux Mono, it does not connect to the external website defined in Connected Services.

Here is the line it is failing on.

loginClient = new LoginServiceClient("WSHttpBinding_ILoginService");

Select all Open in new window

And the error I get back, is (of course), a NullReferenceException as the defined object of 'loginClient' never gets instantiated.

System.NullReferenceException: Object reference not set to an instance of an object.

Select all Open in new window

Has anyone ever successfully taken an EXE file for Windows using Connected Services and run it under Linux Mono?

Thank you,
Jeff

I  am unable to P2V  Linux Machine, details given below:

VCENTER : 6.5
Source Machine: SUSE Linux Enterprise Server 11 SP2
Destination: ESXi 6.5
Convertor: 6.2.0 (correct build)

I am getting various issues and when I resolve one issue, it generates another issue.  

Issue1: FAILED: A general system error occurred:
Network error. Host x.x.x.x key can't be retrieved. (return code 2)

Issue2: FAILED: Unable to obtain the IP address of the helper virtual machine.

Issue3: At Times it is stuck at 1% for a long time.


I did a Google Search and when I resolve one issue, it generates another issue.

I seek guidance from Experts.  VMware has refused to support saying that  the Converter is working fine and something at the OS end.
This is a production server and I really need to do a P2V.

Hi all,

 How to compare string within an array? That string contains backslashes, colon and paranthesis.

sample program:

use strict;
use warnings;

sub perl_func {
    my ($z, $x) = @_;

    print "\n";
    print "z: $z\n\n";
   
    my @lx=@$x;
    foreach my $tx (@lx)
    {
       
        if ($z !~ m|$tx|)
        {
            print "$z !~ $tx\n";
        }
        else
        {
            print "$z == $tx\n";
            return 1;
        }
    }
   
    print "\n";
    return 0;
   

}

#my @x = ("One", "Two", "Three", "Four", "Five");
#my $z = "Four";
#works fine for above x & z

my @x = ("One\\OnesPosition:Num (NumPerl)", "Two\\TensPosition:Num (NumPerl)", "Three\\HundresPosition:Num (NumPerl)", "Four\\ThosandsPosition:Num (NumPerl)", "Five\\TenThousPosition:Num (NumPerl)");
my $z = "Four\\ThosandsPosition:Num (NumPerl)";


if(perl_func($z, \@x))
{
    print "\nfound element\n";
}
else
{
    print "\nnot found element\n";
}

Hi,

I have a security related question on Linux Ubuntu.
Can we remove sudo access to root console for power users.
But still allow admin to ssh to the servers with root password.
As a security measure is it a good idea to disable root access to everyone if  connecting to servers remotely.

Thanks
