Cloudflare err_ssl_protocol_error - Fix it Now ?

This article covers methods to resolve Cloudflare ERR_SSL_PROTOCOL_ERROR. Basically, this error happens as a result of a number of reasons that include wrong DNS settings, SSL mode, TLS version or issues with SSL certificate. 


To fix this error,

1. If you are not the site owner, contact the site owner and let them know you are having issues accessing their site.

2. The domain name has not fully been set to use Cloudflare yet. Check to see if there are non-Cloudflare nameservers that are conflicting with the assigned Cloudflare name servers.

3. You are signed up for Cloudflare, but you have set a DNS record to :grey:. If you have a subdomain or hostname and that serves HTTP/HTTPS traffic, we would advise that you :orange: this DNS record to take advantage of Cloudflare’s security and performance features. See What subdomains are appropriate for :orange:/:grey: clouds? 69

4. The Free Universal SSL certificate hasn’t yet been deployed, :grey: (deactivate) Cloudflare so that your website can continue to use your origin’s SSL certificate. Wait 24 hours and :orange: (activate) Cloudflare again to see if your SSL certificate has been successfully deployed.

5. You have some conflict with TLS 1.3, disable it and see if you still encounter the error.

6. You have selected Full SSL (strict) under your SSL/TLS app, but your origin does not have a valid certificate (i.e., it is expired, self-signed, or not issued by a trusted CA). Temporarily select another SSL option until you have a valid origin certificate in place.

7. Try to look at developer web console (firefox Ctrl+Shift+K) - anything interesting under Security tab.

8. Also, Try to run the command curl -vk on the affected domain.

PrestaShop back office error 500 or blank page - Fix it Now ?

This article covers methods to resolve PrestaShop back office error 500.

The error happens when the Back-office is accessed only from Debug mode activated or in production mode activated. The characteristic of this error is that it only occurs in one of the modes and not in both.

Also, this is an error that is occurring ONLY IN PRESTASHOP STORES VERSION 1.7, and that makes it impossible for us to enter the Back-office, showing an error 500 or the page goes blank. 

That's why we call it a critical mistake, for leaving the store inoperative.


To fix a HTTP 500 error on PrestaShop online store website:

You can activate your web host's FTP or CPanel error reports in your PrestaShop shop.

1.  From PrestaShop v1.4 to v1.5.2

i. Open config/config.inc.php

ii. On line 29, you will find this line: @ini_set('display_errors','off');

iii. Replace it with: @ini_set('display_errors','on');


2. PrestaShop v1.5.3 and later versions (including 1.6 and 1.7)

i. Open config/defines.inc.php

ii. On line 28, you will find this line: define('_PS_MODE_DEV_', false);

iii. Replace it with: define('_PS_MODE_DEV_', true);

Once error reports from the FTP or CPanel are activated, you can browse your store's front or back office to find out what the problem is.


More about Server error 500:

Error 500 means Internal server Error. Whenever a 500 error occurs, the task to return information by the server to the web browser will stop. 

Therefore, as we mentioned above, this is a critical error that would leave the website inoperative.

The 500 errors, as we noted above, are internal server errors and their origin may be in a programming code error on any item that is included and related to the request for information returned by the server to the web browser. 

Therefore, not all 500 errors come from the same source.

# Set the “ea-php72” package as the default “PHP” programming language.
<IfModule mime_module>
  AddHandler application/x-httpd-ea-php72 .php .php7 .phtml
</IfModule>
# php -- END cPanel-generated handler, do not edit

A notice may also be displayed if you're trying to use questionable casting that PHP thinks will not return the result that you want (for example, if you try to forcefully cast an array into a string).

To fix this Joomla warning:

Change PHP's error reporting in the .htaccess file to hide all errors.
You can do that by adding the following code to your .htaccess file:

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on

The above code will ensure that no error whatsoever will be displayed on your website.

Note that if you have an Error Reporting setting in your configuration settings other than "Default", then this setting will override the error reporting defined in your .htaccess.
For example, if your Error Reporting is set to "Maximum", then the above code in your .htaccess file has no effect.

Googlebot cannot access CSS and JS files – Resolve crawl errors ?

This guide covers website crawl errors, Googlebot cannot access CSS and JS files. Google bot and other search spiders will visit the robots.txt file of your website immediately after they hit the htaccess file.

Htaccess has rules to block ip addresses, redirect URLs, enable gzip compression, etc. The robots.txt will have a set of rules for the search engines too. 

They are the reason you received "Googlebot Cannot Access CSS and JS files". 

Robots.txt has few lines that will either block or allow crawling of files and directories. Google has started penalizing websites that block the crawling of js and css files.

The JavaScript and cascading style sheets are responsible for rendering your website and they handle forms, fire events, and so on.

If the JS is blocked, Google bot will not be able to crawl the code and it will consider the code as a spam or violation of link schemes. 

The same logic applies for the CSS files.


To resolve "Googlebot Cannot Access CSS And JS Files" Warning:

1. You need to remove following line: Disallow: /wp-includes/

Depending upon how you have configured your robots.txt file, it will fix most of the warnings. 

You will most likely see that your site has disallowed access to some WordPress directories like this:

User-agent: *

Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/themes/

2. You can override this in robots.txt by allowing access to blocked folders:

User-agent: *
Allow: /wp-includes/js/

SQL Server Error 9002 - Fix it now

This article covers methods to resolve SQL Server Error 9002 for our customers. SQL Server Error 9002 happens when the SQL Transaction Log file becomes full or indicated the database is running out of space. A transaction log file increases until the log file utilizes all the available space in disk. A quick fix is to create more space for log file.


To Fix SQL Server Error 9002:


1. Backup Transaction Log File

Incase, SQL database that you are using is full or out of space, you should free the space. For this purpose, it is needed to create a backup of transaction log file immediately. Once the backup is created, the transaction log is truncated. If you do not take back up of log files, you can also use full or Bulk-Logged Recovery model to simple recovery model.


2. Free Disk Space

Generally, the transaction Log file is saved on the disk drive. So, you can free the disk space which contains Log file by deleting or moving other files on order to create some new space in the drive. The free space on disk will allow users to perform other task and resolve SQL Error Log 9002 The Transaction Log for Database is Full.


3. Move Log File to a Different Disk

If you are not able to free the space on a disk drive, then another option is to transfer the log file into a different disk. Make sure another disk in which you are going to transfer your log file, has enough space.

i. Execute sp_detach_db command to detach the database.

ii. Transfer the transaction log files to another disk.

iii. Now, attach the SQL database by running sp_attach_db command.


4. Enlarge Log File

If the sufficient space is available on the disk then you should increase the size of your log file. Because, the maximum size for a log file is considered as 2 TB per .ldf file.


To enlarge log file, there is an Autogrow option but if it is disabled, then you need to manually increase the log file size.

i. To increase log file size, you need to use the MODIFY FILE clause in ALTER DATABASE statement. Then define the particular SIZE and MAXSIZE.

ii. You can also add the log file to the specific SQL database. For this, use ADD FILE clause in ALTER DATABASE statement.

Then, add an additional .ldf file which allows to increase the log file.

Microsoft SQL Server Error 916 - Fix it now

This article covers method to resolve Microsoft SQL Server Error 916 for our customers.

The main problem is due to bugs present in SQL Server Management Studio that prevents the user to connect to the database and refuses to display the database list.

How to solve Microsoft SQL server error 916:
If you receive the following error while using Microsoft SQL Server Management Studio 2008:
The server principal "username" is not able to access the database "dbname" under the current security context. (Microsoft SQL Server, Error: 916).

Causes of SQL Server Error 916:
1. The user is not permitted to view the data of selected column within the database.
2. The database is currently not available.
3. There are multiple columns such as Size, Space available, Data Space Used, Default file group, Index Space Used, Mail host, Primary file path and user has added at least one of them to the list of Object Explorer Details.
4. If the Auto Close option for the database is enabled, then Collation column cannot be retrieved by SQL Server Management Studio (SSMS).
5. For a database, Collation column contains NULL.

In order to view the granted permissions for the guest-user, the following command is helpful if run by a member of a Sysadmin fixed server.
The query is as follows:

USE msdb;
 SELECT prins.name AS grantee_name, perms.*
 FROM sys.database_permissions AS perms
 JOIN sys.database_principals AS prins
 ON perms.grantee_principal_id = prins.principal_id
 WHERE prins.name = ‘guest’ AND perms.permission_name = ‘CONNECT’;
 GO

On running the above command, a table is presented to the user containing all the attributes of guest user.
However, an empty result shows that guest user is disabled in the database and again the SQL Server error 916 will be displayed.
To overcome the error you may perform the following available solutions.

To fix this SQL server error 916:
1. In Object Explorer, click databases.
2. Display "Object Explorer Details" (F7) or "View –> Object Explorer Details".
3. Right-click the column headers and deselect "collation".
4. Refresh the databases.

Zabbix error Invalid entry when restarting zabbix-agent - Fix it now

This article covers how to fix Zabbix error, an invalid entry when restarting the zabbix-agent which may appear when the configuration file is placed in the wrong path.

The problem is with the configurations:

You are putting the .my.cnf file at the wrong place.

Zabix agent configuration file has prescribed format and parameters defined. 

If you may use Include option to load additional config files, be sure it follows the same format.

So, in your case the .my.cnf file fails to load when you put it under /etc/zabbix/zabbix_agentd.d.

You are missing the part to configure userparameter_mysql.conf file properly.


To resolve this Zabbix error:

1. Move the .my.cnf file from /etc/zabbix/zabbix_agentd.d directory to /etc/zabbix. 

And also remove any Include entry to refere to the .my.cnf file (if there is any). 

The content of the file may look like this:

[mysqld]

user=username

password=userpass


[mysqladmin]

user=username

password=userpass

2. Please make sure that the user listed here exists and have the necessary permissions in mysql.

3. Edit /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf file: You need to replace HOME=/var/lib/zabbix with HOME=/etc/zabbix to point to the right file (should appear three times) as mentioned in the first line of the file.

4. Finally restart the agent: $ service zabbix-agent restart

Libvirt error Unable to resolve address name or service not known

This article covers tips to fix 'Libvirt error: Unable to resolve address: name or service not known'. 

QEMU guest migration fails and this error message appears:

# virsh migrate qemu qemu+tcp://192.168.122.12/system error: Unable to resolve address name_of_host service '49155': Name or service not known

Note that the address used for migration data cannot be automatically determined from the address used for connecting to destination libvirtd (for example, from qemu+tcp://192.168.122.12/system). 

This is because to communicate with the destination libvirtd, the source libvirtd may need to use network infrastructure different from that which virsh (possibly running on a separate machine) requires.


To fix Libvirt error: Unable to resolve address: name or service not known:

The best solution is to configure DNS correctly so that all hosts involved in migration are able to resolve all host names.

If DNS cannot be configured to do this, a list of every host used for migration can be added manually to the /etc/hosts file on each of the hosts. 

However, it is difficult to keep such lists consistent in a dynamic environment.

i. If the host names cannot be made resolvable by any means, virsh migrate supports specifying the migration host:

# virsh migrate qemu qemu+tcp://192.168.122.12/system tcp://192.168.122.12

Destination libvirtd will take the tcp://192.168.122.12 URI and append an automatically generated port number. 

ii. If this is not desirable (because of firewall configuration, for example), the port number can be specified in this command:

# virsh migrate qemu qemu+tcp://192.168.122.12/system tcp://192.168.122.12:12345

iii. Another option is to use tunnelled migration. Tunnelled migration does not create a separate connection for migration data, but instead tunnels the data through the connection used for communication with destination libvirtd (for example, qemu+tcp://192.168.122.12/system):

# virsh migrate qemu qemu+tcp://192.168.122.12/system --p2p --tunnelled

Apply Configuration never completes in Nagios - Fix this issue now

This article covers methods to resolve the issue, Apply Configuration never completes in Nagios. The backend components in Nagios XI require high level privileges, these are accommodated for in sudoers entries.

This allows for high level commands to be executed by scripts without requiring user input. If these entries are missing then they can cause unexpected results.


Sometimes when creating a large amount of objects the apply configuration process is taking longer than expected and PHP may time out or exceed limits.

These are defined in the php.ini file, The location of the php.inifile differs depending on your operating system / version. The following command will determine the location:

find /etc -name php.ini

If there are multiple results then the one in the apache directory is the one that needs changing.

Edit /etc/php.ini and increase these values:

max_execution_time = 60

max_input_time = 60

memory_limit = 256M

 

After making these changes you'll need to restart the Apache service using one of the commands below:

RHEL 7 | CentOS 7 | Oracle Linux 7

$ systemctl restart httpd.service

Debian | Ubuntu 16/18

$ systemctl restart apache2.service

Port 113 IDENT Requests - How to Disable it on Nagios

This article covers how to disable Port 113 IDENT Requests on Nagios. 

You are seeing port 113 return requests either from your Nagios XI server (when submitting NSCA passive results) to the originating host OR you are seeing port 113 return requests when checking NRPE services).

You will see this behavior on your firewall logs as you will most likely not have a firewall rule for port 113.

This is usually because you are running an NRPE check through XINETD with USERID included on the log_on_success or log_on_failure options in your remote hosts /etc/xinetd.d/nrpe file.

OR this could be because you are submitting passive results to the XI server through NSCA (which is running under XINETD) /etc/xinetd.d/nsca with the same options as above.


To disable Port 113 IDENT Requests:

1. Then remove the USERID option from the log_on_failure AND log_on_success to stop the IDENT from occurring. The file you need to change depends on:

i. NRPE on remote host

/etc/xinetd.d/nrpe

ii. NSCA on Nagios XI server

/etc/xinetd.d/nsca

2. After making the changes you need to restart the xinetd service using one of the commands below:

RHEL 7+ | CentOS 7+ | Oracle Linux 7+ | Debian | Ubuntu 16/18/20

$ systemctl restart xinetd.service


What is filter ident port 113?

Filter IDENT(port 113) (Enabled) IDENT allows hosts to query the device, and thus discover information about the host.

On the VPN Passthrough screen, you can configure the router to transparently pass IPSec, PPPoE, and PPTP traffic from internal hosts to external resources.

Segmentation fault in Nagios - Fix it Now

This article covers how to fix the Segmentation fault in Nagios.

A segmentation fault (aka segfault) is a common condition that causes programs to crash; they are often associated with a file named core .

Segfaults are caused by a program trying to read or write an illegal memory location.


What does segmentation fault mean in Linux?

A segmentation fault is when your program attempts to access memory it has either not been assigned by the operating system, or is otherwise not allowed to access. "segmentation" is the concept of each process on your computer having its own distinct virtual address space.


Typical causes of a segmentation fault:

1. Attempting to access a nonexistent memory address (outside process's address space)

2. Attempting to access memory the program does not have rights to (such as kernel 3. structures in process context)

4. Attempting to write read-only memory (such as code segment)


To fix Segmentation Fault (“Core dumped”) in Ubuntu:

1. Remove the lock files present at different locations.

2. Remove repository cache.

3. Update and upgrade your repository cache.

4. Now upgrade your distribution, it will update your packages.

5. Find the broken packages and delete them forcefully.

ERROR: PleskDBException: Unable to connect to database - Fix it now

This article covers methods to resolve error: pleskdbexception: unable to connect to database which triggers as a result of various reasons that include InnoDB engine corruption, disk space full, data directory not completely restored or recovered, and so on. 

The reason of this error is due to disk full and you need to delete extra file from my linux Server.

fslint is a Linux utility to remove unwanted and problematic cruft in files and file names and thus keeps the computer clean. A large volume of unnecessary and unwanted files are called lint. fslint remove such unwanted lint from files and file names.


To Clear RAM Memory Cache, Buffer and Swap Space on Linux:

1. Clear PageCache only. # sync; echo 1 > /proc/sys/vm/drop_caches.

2. Clear dentries and inodes. # sync; echo 2 > /proc/sys/vm/drop_caches.

3. Clear PageCache, dentries and inodes. # sync; echo 3 > /proc/sys/vm/drop_caches.

4. Sync will flush the file system buffer. Command Separated by “;” run sequentially.


To find largest files including directories in Linux is as follows:

1. Open the terminal application.

2. Login as root user using the sudo -i command.

3. Type du -a /dir/ | sort -n -r | head -n 20.

4. du will estimate file space usage.

5. sort will sort out the output of du command.


To uninstall an RPM package:

1. Execute the following command to discover the name of the installed package: rpm -qa | grep Micro_Focus. This returns PackageName , the RPM name of your Micro Focus product which is used to identify the install package.

2. Execute the following command to uninstall the product: rpm -e [ PackageName ]

isc-dhcp-server Job failed to start - Resolve it now

This article covers method to resolve DHCP 'isc-dhcp-server: Job failed to start' error. Basically, 'isc-dhcp-server: Job failed to start' error can happen if there is any issues with the commands that we run.


You can try to restart the service; if it really is an issue with the service starting before the network is up restarting it once the network is up should work:

$ sudo systemctl start restart isc-dhcp-server.service


If that doesn't work then try and investigate further why it's not starting by first getting the current status of the service:

$ sudo systemctl status isc-dhcp-server.service


That should also give you a PID for which you can further investigate with journaltctl where XXXX is the PID of the service:

$ journalctl _PID=XXXXX


Also, what caused/led you to do the following? Perhaps try undoing those changes as I'm not sure if that's helping or hurting. Was the /etc/init/isc-dhcp-server.conf file already there or did you manually create it?

So add a "Sleep 30" to the /etc/init/isc-dhcp-server.conf file. Also add " up service dhcp3-server restart " to my  /etc/network/interfaces file.

Icons images and javascript files missing from frontend in Magento - Fix it now

This article covers methods to resolve Magento error related to with icons, images, and javascript files missing from frontend. Basically, icons, images, and javascript files might not appear if we use the wrong Magento update command to upgrade the version.


If you are in production mode, and are running setup:upgrade and you don't want regenerate static content because there is no need to, then you can use the following:

php bin/magento setup:upgrade --keep-generated

--keep-generated is an optional argument that does not update static view files. 

It should be used only in production mode. 

It should not be used in developer mode.


Solutions for the issue where stylesheets and images do not load after installing Magento ?

The following are possible solutions depending on the software you use and the cause of the problem:

If you are using the Apache web server, verify your server rewrites setting and your Magento server's base URL and try again. If you set up the Apache AllowOverride directive incorrectly, the static files are not served from the correct location.

If you are using the nginx web server, be sure to configure a virtual host file. The nginx virtual host file must meet the following criteria:

The include directive must point to the sample nginx configuration file in your Magento installation directory. For example:

include /var/www/html/magento2/nginx.conf.sample;

The server_name directive must match the base URL you specified when installing Magento. For example:

server_name ip_address;

If the Magento application is in production mode, try deploying static view files using the command magento setup:static-content:deploy.

WordPress 405 Method Not Allowed Error - Fix it now

This article covers different methods to troubleshoot 405 Method Not Allowed Error on WordPress.

The 405 Method Not Allowed WordPress error occurs when the web server is configured in a way that does not allow you to perform a specific action for a particular URL.

Disable database UTF8 connectivity on Nagios - How to do it

This article covers how to configure disable UTF8 connectivity to the MySQL/MariaDB databases. By default Nagios XI uses UTF8 however sometimes this needs to be disabled to allow MySQL / MariaDB to define the connectivity method.

This configuration ensures that characters from different languages can be correctly stored and retrieved in the databases.


The Nagios XI Configuration Directive

The following configuration directive was added in Nagios XI 5.4.13:

$cfg['db_conn_utf8'] = 0;

 To determine if you currently have that directive enabled, establish a terminal session to your Nagios XI server as the root user and execute the following command:

$ grep db_conn_utf8 /usr/local/nagiosxi/html/config.inc.php

 If the grep command produces NO output then the directive does not exist in your configuration and it needs to be added. This can be added with the following command:

$ printf "\n\$cfg['db_conn_utf8'] = 0;\n" >> /usr/local/nagiosxi/html/config.inc.php

 

If the grep command produced output then it can be changed with the following command (sets it to 0):

$sed -i "s/db_conn_utf8'\] =.*/db_conn_utf8'\] = 0;/g" /usr/local/nagiosxi/html/config.inc.php

Defining the directive to 0 will resolve the issue you for garbled or ??? characters.


If you wanted to change it to 1 then use the following command:

$sed -i "s/db_conn_utf8'\] =.*/db_conn_utf8'\] = 1;/g" /usr/local/nagiosxi/html/config.inc.php

 

The change takes effect immediately.

Troubleshoot DNS issues - Step by Step tips to resolve it

This article covers how to troubleshoot DNS issues. One of the handiest tools for troubleshooting DNS failures is the NSLOOKUP command, which you can access from a Windows Command Prompt window. Simply type NSLOOKUP followed by the name of the host for which you want to test the name resolution.

Basically, DNS errors are caused by problems on the user end, whether that's with a network or internet connection, misconfigured DNS settings, or an outdated browser. They can also be attributed to a temporary server outage that renders the DNS unavailable.


DNS: online name resolution:

The domain name system (DNS) is a directory service used for transforming alphanumeric domain names into numeric IP addresses. 

A decentralized process, name resolution generally takes place on DNS servers’ networks distributed throughout the world. 

Every internet address you enter into your web browser’s search bar is then forwarded by your router to a DNS server. This server then dissolves the domain name into a numeric sequence and returns a corresponding IP address. 

Should the DNS server fail to produce an answer, then it won’t be possible to access the desired website; the result is the error message ‘DNS server not responding’.


To  clear your DNS cache:

1. On your keyboard, press Win+X to open the WinX Menu.

2. Right-click Command Prompt and select Run as Administrator.

3. Run the following command: ipconfig /flushdns.


To Troubleshoot DNS issues:

The root of such irritating messages can often be traced back to the server outage. In such cases, the DNS server is temporarily unavailable. Most of the time, these problems can be corrected by changing browsers, switching a few of your firewall settings, or restarting your router.

1. In order to rule out that the connection problem isn’t being caused by your web browser, carry out a test by attempting to logon on to the desired web page with alternative applications.

2. In case you aren’t able to achieve your desired results simply by changing browsers, then the next step is to rule out Windows Firewall as the possible culprit.

3. Connection problems can often be solved by restarting the server. Most devices include a power button specifically for this purpose. Should this fail to yield any results, then it looks like a hard reboot may be in store; this is done simply by pulling out the power plug. 

4. If you have ruled out common causes of error such as the router software crashes or conflicts with Windows Firewall, then changing your DNS server could be the solution.



How to Check DNS server?

You can find out whether changing DNS server has solved the problem by carrying out a simple test. 

Enter the URL of a well-known site in your browser (e.g. www.google.com). 

If the site can be accessed it means the DNS server is functioning properly.

If the site can't be accessed, you can enter the following IP address into your browser: 172.217.16.195. 

This is one of Google’s IP addresses. If Google doesn't appear after entering the address, it probably means there's a general internet problem rather than a problem with the DNS server.

Unable to allow access for disk path in libvirtd - Fix it Now

This article covers tips to fix the error Unable to allow access for disk path in libvirtd. By default, migration only transfers the in-memory state of a running guest (such as memory or CPU state). Although disk images are not transferred during migration, they need to remain accessible at the same path by both hosts.


To fix Unable to allow access for disk path in libvirtd error:

Set up and mount shared storage at the same location on both hosts. The simplest way to do this is to use NFS:

1. Set up an NFS server on a host serving as shared storage. The NFS server can be one of the hosts involved in the migration, as long as all hosts involved are accessing the shared storage through NFS.

# mkdir -p /exports/images
# cat >>/etc/exports <<EOF
/exports/images    192.168.122.0/24(rw,no_root_squash)
EOF


2. Mount the exported directory at a common location on all hosts running libvirt. For example, if the IP address of the NFS server is 192.168.122.1, mount the directory with the following commands:

# cat >>/etc/fstab <<EOF
192.168.122.1:/exports/images  /var/lib/libvirt/images  nfs  auto  0 0
EOF
# mount /var/lib/libvirt/images

The URI Failed to Connect to the Hypervisor - Fix it now

This article covers methods to resolve hypervisor error. The error message is misleading about the actual cause. This error can be caused by a variety of factors, such as an incorrectly specified URI, or a connection that is not configured.


To fix THE URI FAILED TO CONNECT TO THE HYPERVISOR:

1. Incorrectly specified URI

When specifying qemu://system or qemu://session as a connection URI, virsh attempts to connect to host names system or session respectively. This is because virsh recognizes the text after the second forward slash as the host.

Use three forward slashes to connect to the local host. For example, specifying qemu:///system instructs virsh connect to the system instance of libvirtd on the local host.

When a host name is specified, the QEMU transport defaults to TLS. This results in certificates.


2. Connection is not configured

The URI is correct (for example, qemu[+tls]://server/system) but the certificates are not set up properly on your machine. For information on configuring TLS, see Setting up libvirt for TLS available from the libvirt website.

Manually Migrate Accounts to cPanel

This article covers how to manually #migrate accounts to cPanel/WHM, as well as the steps to fix common errors faced while migrating.


After you migrate your files to your new cPanel & WHM server, perform the following steps:

1. Confirm that all of the content and credentials migrated properly and that they function in the new environment.

2. Update your domain's nameservers to match the new nameservers on your cPanel & WHM server.

3. Create cPanel and reseller accounts. To do this, use WHM's Create a New Account interface (WHM >> Home >> Account Functions >> Create a New Account).


After you create the new #cPanel & #WHM account, migrate the old server’s files and directories to the appropriate locations on your new server.


Generally, you will migrate the following files and directories during this process:

1. The public_html directory contains all of your files, directories, subdirectories, and content. This directory may appear as the /home/user/www directory or the /home/user/vhost directory on some systems.

2. The /home/user/mail directory contains all of the email files for all of the cPanel account’s email accounts.

Ignore permission denied message from find command in Linux

This article covers how to resolve the error 'ignore permission denied message from find' which occurs while running a 'find' command in Linux.
The find command is used to locate files on a Linux or Unix like operating system.
The find command will search directory to match the supplied search criteria.
You can search for files by type, name, owner, group, date, permissions and more. By default the find will search all subdirectories for you.

Linux divides the file permissions into read, write and execute denoted by r,w, and x.
The permissions on a file can be changed by 'chmod' command which can be further divided into Absolute and Symbolic mode.
The 'chown' command can change the ownership of a file/directory.

If you prefer using the command line, you can easily find a file's permission settings with the ls command, used to list information about files/directories.
You can also add the –l option to the command to see the information in the long list format.

To change directory permissions in Linux, use the following:
1. chmod +rwx filename to add permissions.
2. chmod -rwx directoryname to remove permissions.
3. chmod +x filename to allow executable permissions.
4. chmod -wx filename to take out write and executable permissions.

Troubleshoot KVM Virtualization Problem

This article covers how to troubleshoot KVM virtualization problem.


Log file locations and tools used to track down #KVM #problems are:

2. $HOME/.virt-manager/virt-manager.log – virt-manager tool log file.
3. /var/log/libvirt/qemu/ – Log files for each running virtual machine. If centos is virtual machine name, than log file is /var/log/libvirt/qemu/centos.log.

You can use the grep and other Linux tools to view this files:
# tail -f /var/log/libvirt/qemu/freebsd.log
# grep something $HOME/.virtinst/virt-install.log
$ sudo tail -f /var/log/libvirt/qemu/openbsd.log

Hyper-V backups can fail for any number of reasons, but there are some things to look for when backups don’t work the way that they are supposed to.

Specifically, you need to determine if the problem is confined to a particular host, a particular virtual machine, or perhaps related to the backup target itself.

Failed to restart network service CentOS error

This article covers methods to fix 'Failed to restart network.service' on both RHEL 7 and RHEL 8. You can use "NetworkManager.service" as the default networking service in RHEL 8.
Red Hat Enterprise Linux 8 uses the default networking service, NetworkManager, which is a dynamic network control and configuration daemon to keep network devices and connections up and active when they are available.

If any of these scripts are required, the installation of the deprecated network scripts in the system is still possible with the following command:

# yum install network-scripts

In RHEL 7 /etc/rc.d/init.d/network was owned by initscripts but with RHEL 8 this tool is part of network-scripts rpm.

Also, you can restart you network by issuing following command:

sudo systemctl restart NetworkManager.service


You can also stop and start it by issuing:

sudo systemctl stop NetworkManager.service
sudo systemctl start NetworkManager.service

This article will guide you on ways to resolve #Server sent passive reply with unroutable address which occurs due to bad server settings or when an FTP client is behind #NAT. 

#FileZilla has updated their FTP #client, and FTP over TLS is now used by default. This results in clients being unable to connect to their server from the outside network.

WordPress Not Sending Email error

If you're experiencing issues with WordPress failing to send emails – for example, sending forms or other communications – it's usually due to problems with your server configuration. 

If your WordPress email is not being sent, switch over to SMTP (Simple Mail Transfer Protocol) instead.

WordPress has several SMTP plugins you can use to force any FROM address you like.

This is important for two major reasons: 

i. It allows you to send email directly through your mail server as opposed to the web server. 

ii. It allows you to send email FROM another email host.

One major reason why this happens is that webhost disable the PHP Mail function because it is very easy to exploit by spammers and hackers.

When WordPress wants to send emails, it calls on the email server in your webhost using the PHP Mail function, but if this function is disabled by your webhost, your requests to send emails will not even get to your mail server.

WordPress fails to send email as a result of the SMTP server on the underlying operating system not being configured properly. 

Proper configuration includes using authentication, configuring the basic SMTP server settings, and following best practices when setting up SPF records, and so on.

This article will guide you on the method to fix WordPress not sending email issue.

This is a rich command that can work with many different parameters so you'd better insert "clamscan –-help" on the terminal first and see the various things that what you can do with it:

$ clamscan –-help


To Update ClamAV Signature Database:

1. Stop the ClamAV process:

$ systemctl stop clamav-freshclam

2. Manually update the ClamAV signature database:

$ freshclam

3. Restart the service to update the database in the background:
