How to generate SSH key for Windows machine

If you are using Windows operating system on your local machine, then you can use SSH terminal application such as putty which is available at http://www.chiark.greenend.org.uk/%7Esgtatham/putty/download.html

If you are using Windows 10 or later version, you may directly generate SSH key from your terminal. However, putty may also work on Windows 10, thus helping as universal ssh terminal for Windows machine.

Once you have downloaded Putty, Open PuTTYgen.

Under Parameters specify the following:

  • Type of key to generate: RSA
  • Number of bits in a generated key: 2048 or more

Click Generate and follow the on-screen instructions.

The tool displays the public key value.

In the Key comment section, replace the pre-populated text with your username. For example, johnssh, or johnssh_xxxx_com.

Hit enter for Key passphrase to remain as none.

Click Save private key to choose a location to save the private key to.

PuTTYgen writes the private key to a file with a .ppk extension.

Click Save public key to choose a location to save your public key to. Keep the PuTTYgen window open.

Copy the text from the Public key for pasting into OpenSSH authorized_keys file field.

Open the public key file. The public key has a format similar to the following:

---- BEGIN SSH2 PUBLIC KEY ----
Comment: "johnssh"
KEY_VALUE
---- END SSH2 PUBLIC KEY ----

Replace the entire contents of the public key file with the value you copied from the Public key for pasting into OpenSSH authorized_keys file field, so that your public key file matches the following format:

KEY_VALUE johnssh

A public key for the user johnssh looks similar to the following:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDAu5kKQCPF... johnssh

You will now need to add above key to your remote SSH authorized_keys file which is usually located under /root/.ssh

How to generate SSH key for Linux?

Assuming you are using Linux operating system on your local machine, you can generate SSH to gain access to your remote server using SSH with key based authentication enabled.

You can generate SSH key using below command :

ssh-keygen -t rsa

Above command will prompt you to enter :

Enter file in which to save the key (/root/.ssh/id_rsa): 

Enter to select the default file location.

Enter passphrase (empty for no passphrase):

Enter to keep the password as nil / blank one, i.e without any password. Repeat the same for “Enter same passphrase again:”

You will then receive message, “Your public key has been saved in /root/.ssh/id_rsa.pub”

Now you have to include above id_rsa.pub key in your server’s authorized_keys file which is located at /root/.ssh/

This will help you to gain key based access to your server.

MySQL Databases interface to show MySQL as offline, Updating MariaDB to v10.2.35 or v10.3.26

WebhostUk

Upgrading MariaDB to v10.2.35 or v10.3.26 causes the cPanel UI to not read the grants properly, which leads to cause select sites to be inaccessible and the MySQL Database page within the cPanel interface returns the following error.

More important to note that MariaDB should still be running, the cPanel error log should populate the string the UI is having issues reading:

[2020-11-05 07:37:27 +0000] warn [cpmysql] Error (Invalid grant string: SET DEFAULT ROLE 0 FOR '$user'@'$host'
) while parsing grant: SET DEFAULT ROLE 0 FOR '$user'@'$host' at /usr/local/cpanel/Cpanel/Mysql.pm line 956, <STDIN> line 1.
        Cpanel::Mysql::__ANON__(__CPANEL_HIDDEN__...) called at /usr/local/cpanel/3rdparty/perl/530/lib/perl5/cpanel_lib/Try/Tiny.pm line 118

cPanel has opened an internal case for their development team to investigate this further.

For reference, the case number is CPANEL-34745.

Follow this article to receive an email notification when a solution is published in the product. 

Before proceeding with these changes, we encourage you to backup your database in the event a restore is required.

To backup the MySQL database directory, the following command can be executed as root:

mysqldump mysql > /backup/mysql.sql

Once backup is complete, you can proceed with altering that database column order.

The following command performs the appropriate alterations for the database:

mysql -e "ALTER TABLE mysql.user MODIFY IF EXISTS password_last_changed timestamp DEFAULT CURRENT_TIMESTAMP NULL AFTER max_statement_time, MODIFY IF EXISTS password_lifetime smallint unsigned DEFAULT NULL AFTER password_last_changed, MODIFY IF EXISTS account_locked enum('N', 'Y') COLLATE utf8_general_ci DEFAULT 'N' NOT NULL after password_lifetime;"

Apply the change by restarting the MariaDB service:

/scripts/restartsrv_mysql

They should go into effect immediately. 

yum versionlock clear

Then run upcp to have the MariaDB packages updated:

/scripts/upcp

Inode

What is an inode.

An inode is a data structure used to represent a filesystem object, which can be one of various things including a file or a directory. Each file has a single inode, even though they can have different names.

In other words, the number of inodes equals the total number of files and directories on your hosting plan. To ensure optimal performances, we limit the number of inodes upto 250 000 on most of the hosting plan.

Where can I see how many inodes I use.

To check how many inodes are used, log in to your cPanel. In the left sidebar, click on the Statistics icon. Under Disk Space, you will find Files Usage. This equals to your inode usage.

Steps to reduce inode usage.

There are several ways to reduce inode usage.

Delete useless files, old backups and websites

In your cPanel with the File Manager or through a FTP client, you can easily sort and delete files and directories that are not necessary. These can be scripts not in use, old development websites, unused image files…

Remove cache files

Some applications (such as Joomla, Drupal or WordPress for instance) generate a number of cache files used to improve performances. Verifying how big these cache files are and deleting them once in a while is a good practice. You should be able to remove cache files easily directly in the app.

Archive old emails

Every email on your hosting plan adds up to the total number of inodes. It is a good practice to archive older emails or to transfer them to your computer to limit their size on the server.

Also, it is necessary to check the catchall email address that can accumulates thousands of emails and therefore inodes.

Verify where error messages from scripts and CRON tasks go

If your CRON tasks generate error messages, they can be stored (and take a lot of room) on your server. It is important to check where the error messages go in order to reduce inode usage

How to enable Cloudflare with Railgun

A tutorial that will guide you about how to enable CloudFlare with Railgun for your website.

Cloudflare is a CDN that allows to enhance your website performance, speed and latency with the help of their distributed network across the globe!

Cloudflare offers a premium feature called as Railgun which helps improving the website load times, especially for dynamic websites such as WordPress devloped websites, Drupal, Joomla etc.

Railgun ensures that the connection between your origin server and the Cloudflare network is as fast as possible. It is a premium plugin from Cloudflare which is available as a paid feature. However, we at WebHostUK, being an exclusive Cloudflare partner, offer Railgun for free for websites hosted on our server.

Below tutorial will explain you how to enable Cloudflare with Railgun on our servers.


  • Once your order is processed and your account is enabled, you will gain cpanel access to your account, where Cloudflare tool is available under “Software” section as visible in below screenshot:

  • Click on Cloudflare and it will then redirect you to Cloudflare setup wizard

  • You can use any of your existing Cloudflare account or create a new one. If you already have an account with Cloudflare, then please make sure that the domain (for which you are intending to add Railgun) is not existing in your Cloudflare account. If it is so, kindly delete it from your Cloudflare.com portal login.

  • To integrate Cloudflare, you have two options:

i. Partial setup also known as CNAME setup of website with Cloudflare : In this setup, your domain will use our nameservers and the CNAME of “www” prefix of your domain will be resolving to Cloudflare alias domain name.

Pro’s of CNAME Cloudflare setup : DNS zones are configured on our server which means, you do not need to do any manual DNS changes for your domain or its MX records or subdomains. These DNS records are automatically configured in DNS zones on our servers.

Con’s of CNAME Cloudflare setup : Since only “www” prefix is configured with Cloudflare alias hostname, Cloudflare with Railgun for the respective website will only work if domain is accessed with www prefix. If the website is not accessed with www prefix, Railgun will not work. So you will have to force redirect your website to its www prefix using rules in .htaccess


ii. CloudFlare DNS Managed setup or full setup : In Cloudflare DNS managed setup, your domain will use Cloudflare nameservers which means all host records including “A”, “MX”, “NS”, “SPF”, “DKIM” etc are all hosted on Cloudflare servers. Cloudflare will control DNS for your domain and we no longer have any DNS control for your websites or its subdomains.

Pro’s of Cloudflare DNS managed setup: Cloudflare with Railgun will work for domain with or without “www” prefix. This eliminates the need of any such redirect of website from non-www url to www url

Con’s of Cloudflare DNS managed setup: Since Cloudflare will manage your DNS, you will need to manually add MX, SPF or DKIM records in Cloudflare DNS portal. Whenever you create any subdomain, its entry will also need to be manually added in Cloudflare DNS portal.


  • Once you have enabled Cloudflare for your domain using any of “cname or cloudflare dns managed setup” as explained above, you will now need to request for enabling Railgun for your domain. In order to request enabling “Railgun” for your domain, you will need to submit a request at : https://www.webhostuk.co.uk/railgun-request.php

Your submitted request will raise a support ticket under your account, and our 24/7 support team will then enable Railgun for your requested domain and update you via your support ticket.

How to check if Cloudflare with Railgun is working for your website?

To check if cloudflare with Railgun is working properly for your website, you need to take help of an extension plugin which is available for Google Chrome Browsesr : https://chrome.google.com/webstore/detail/claire/fgbpcgddpmjmamlibbaobboigaijnmkl

Cloudflare if sucessfully enabled for your website and when accessed in Chrome, will show “red” dot as seen in below image

How to Check if Railgun is Running on Website

When a request is handled by Railgun, Cloudflare inserts a header with diagnostic information to track how the protocol is doing. If you want to see these headers, you’ll need to use a browser that supports examining header information.

View Railgun header in browser

Google Chrome: View > Developer > Developer Tools menu. You can also install Cloudflare’s Claire extension.

Safari: Develop > Show Web Inspector menu

Firefox: Install Firebug

Microsoft Internet Explorer: You can use a tool like Fiddler

When you are looking for the header information, you should be seeing Cloudflare headers like the following in the response:

cf-railgun:   e95b1c46e0 0.02 0.037872 0030 9878

cf-ray:   478149ad1570291

The CF-Railgun header has up to five codes separated by a space. In order, these codes and their corresponding values from the example of cf-railgun: e95b1c46e0 0.02 0.037872 0030 9878 listed above are:

  • Railgun Request ID: e95b1c46e0 (internal process number that allows us to track what connection handled a request )
  • Compression Ratio: 0.02 (the size of the response after Railgun’s delta compression expressed as a percentage)
  • Origin Processing Time: 0.037872 (that Railgun waits for the origin web server to generate the page)
  • Railgun Flags: 0030 (how a request was processed)
  • Version Number: 9878 (indicates the version of the Railgun Listener software on the origin server’s network)
