What is a 301 redirect?
==================
A 301 redirect is the preferred method to preserve your current search engine rankings when redirecting web pages or a web site. The code "301" means that the page has "moved permanently".
How to set up the 301 Redirect?
To create a .htaccess file: open notepad, name and save the file as .htaccess. (be careful not to save the file as txt)
If you already have a .htaccess file on your server, download it to your desktop for editing.
Copy this code into your .htaccess file:
redirect 301 old.htm http://www.domain.tld/new.htm
If the .htaccess file already has lines of code in it, skip a line first
Save the .htaccess file
Upload this file to the root folder of your server.
To test it, simply try to load the old site or page in your browser. You should be redirected immediately

How to change the primary IP addres of a WHM/cPanel server
==================
Refer this http://www.codero.com/knowledge-base/questions/248/How+to+change+the+primary+IP+addres+of++a+WHM%7B47%7DcPanel+server
Steps in WHM:
Log into WHM and go to Basic cPanel & WHM Setup
Change the Primary IP here with the option that says "The IP address (only one address) that will be used for setting up shared IP virtual hosts"
Note: This might not actually be necessary.
Log in to SSH, and do the following:
Edit /etc/sysconfig/network-scripts/ifcfg-eth0
Change the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip
Edit /etc/sysconfig/network
Change the GATEWAY line here if it does not exist in the ifcfg-* file.
Edit /etc/ips
Remove the new primary IP from this file if it is present
Add the old primary IP to this file with the format <IP address>:<Net Mask>:<Gateway>
Edit /var/cpanel/mainip
Replace the old primary IP with the new primary IP
Edit /etc/hosts
Replace the old primary IP with the new one if needed. The hostname's dns will need to be updated too
Restart the network service to make the new IP the primary
service network restart
Note: You're probably going to be disconnected at this point, and have to log in to ssh using the new primary ip.
Restart the ipaliases script to bring up the additional IPs
service ipaliases restart
Run ifconfig and make sure all IPs show up correctly
Update the cpanel license to the new primary IP
Verify you can still log in to WHM and there is no license warning

Error: Domain has exceeded the max defers and failures per hour allowed
Refer http://www.lilio.com/helpdesk/knowledgebase.php?action=displayarticle&id=29)
https://forums.cpanel.net/threads/domain-example-com-has-exceeded-the-max-defers-and-failures-per-hour-5-5.296962/
/var/cpanel/email_send_limits/max_deferfail_example.com
Deleting this file fixed the problem immediately.
==============
If your email is returned with error messages similar to the following, you may have sent too many bounced or deferred messages within one hour.
Domain has exceeded the max defers and failures per hour (5/5 (100%)) allowed. Message discarded.
To avoid misuse by spammers and subsequent blacklisting of the server in spam databases, all email errors are tracked. If more than 50% of email sent from a particular domain within one hour is bounced or deferred by the recipient server, a temporary block on sending additional email will be activated for that domain. After the hour has passed, this block will be automatically lifted.
Important terms
Bounced: Any email messages that are returned with an error status.
Deferred: This usually indicates that the message could not be delivered to the recipient's server, but that additional attempts will be made. In most cases, email servers will attempt to deliver deferred messages several times over a 24 hour period. If the receiving email server becomes available again within this time period, the message will be delivered.

1- This error is typically seen due to a setting in the CSF firewall or another firewall. It might be caused by having the following set:
SMTP_BLOCK = 1
SMTP_ALLOWLOCAL = 0
You would need to change SMTP_ALLOWLOCAL to 1 to enable webmail to function.
2- Check for root@hp160 [~]# cat /var/log/maillog | grep children
Dec 13 03:40:53 hp160 spamd[13640]: prefork: adjust: 0 idle children less than 1 minimum idle children. Increasing spamd children: 631146 started.

Perhaps the DBD::mysql perl module hasn't been fully installed
==========================
Error:
install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at (eval 5) line 3.
Perhaps the DBD::mysql perl module hasn't been fully installed,
or perhaps the capitalisation of 'mysql' isn't right.
Available drivers: DBM, ExampleP, File, Gofer, Proxy, SQLite, Sponge.
Solution:

fix for Eaccelerator filling up /tmp folder – WHM & CPanel
http://kb.eurovps.com:8090/pages/viewpage.action?pageId=5472289
==============
If you simply want to clean out the /tmp/eaccerlator folder, the following command does the trick on CentOS and RedHat systems.
tmpwatch --mtime --all 336 /tmp/eaccelerator
Other thing is to move the eaccerlator cache directory from /tmp to other large pattion space.
vi /usr/lib/php.ini
Find :
eaccelerator.cache_dir=”/tmp/eaccelerator
and change it from /tmp/eaccelerator to /var/cache/eaccelerator and save the file.
# mkdir /var/cache/eaccelerator
#service httpd stop
#rm -rf /tmp/eaccelerator
#service httpd start

Reset The Root Password For A Linux VM Hosted On XenServer
https://www.unixmen.com/reset-root-password-linux-vm-hosted-xenserver/
=========================
1- Shut down your server using the Xencenter controls
2- Right click on machine and select Properties
3- Go under Boot options
You already have something in the OS Boot Parameters you will need to take note of this as You will need to save it and put it back once the password reset is complete.
Change the OS Boot Parameters to rw init=/bin/bash
Some times for some OS especial CentOS you will need to write in the field the word single instead of rw init=/bin/bash so try both if first trick didn’t work.
4- Save and Start your virtual machine
Your system will boot up in single user mode. So to change your password, you need to type this command:
bash# passwd root
5- Type in your new password you will then be asked to confirm it
Your password has now been reset.
6- Shutdown your virtual machine.
bash# shutdown -h now

How to change boot device on vm installed on Citrix Xen Server to DVD
Ref - http://www.xenlens.com/boot-a-guest-vm-from-cd-or-dvd-in-xenserver/
---------------------
In order to boot from cd or dvd you need to change the guest virtualization type from HVM (fully virtualized) to PV (paravirtualized).
# xe vm-param-set HVM-boot-policy="BIOS order" uuid=[uuid of your vm]
After you have booted from dvd, change back to fully virtualized mode:
# xe vm-param-set HVM-boot-policy="" uuid=[uuid of your vm]
---------------------
Ref URL: https://blogs.msdn.microsoft.com/virtual_pc_guy/2015/02/11/copying-the-vhd-of-a-generation-2-linux-vmand-not-booting-afterwards/

/boot/efi/EFI/ubuntu
-------------------------------------------------
Log in to the virtual machine.
Change directory to the boot EFI directory : cd /boot/efi/EFI
Copy the ubuntu directory in to a new directory named boot : sudo cp –r ubuntu/ boot
Change directory to the newly created boot directory : cd boot
Rename the shimx64.efi file : sudo mv shimx64.efi bootx64.efi
-------------------------------------------------
What this does is move the boot information out of the UEFI firmware and onto the disk. With this done you can copy and boot the virtual hard drive with ease.
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --no-nvram --removable
-------------------------
What command above that does is it properly re-installs grub to /boot/efi/EFI in removal mode. (i.e. using the well known /EFI/BOOT/BOOTX64.EFI bootfile).

How to setup Mailjet on exim for cPanel dnsonly on Google Cloud .
----------------
https://desantolo.com/2016/12/how-to-setup-mailjet-on-exim-for-cpanel-dnsonly-on-google-cloud/2/
What EXIM needs to have in it’s configuration explained:
First we need to add the authentication credentials for the login. In /etc/exim.conf search for “begin authenticators” immediately below copy and paste my code and make sure to add your API key and password.
mailjet_login:
driver = plaintext
public_name = LOGIN
client_send = : {YOUR_API_KEY_GOES_HERE} : {YOUR_PASSWORD}
Now we need to tell exim how to route mail and the rules to bound emails to (basically anything that is not local mail to use the new transport we will be creating on step 3). Search for “begin routers” paste my code and make sure to edit “in-v3.mailjet.com” with the server where your mailjet account got provisioned. You can obtain this from mailjet’s “configure my SMTP”
send_via_mailjet:
driver = manualroute
domains = ! +local_domains
transport = mailjet_smtp
route_list = "* in-v3.mailjet.com::2525 byname"
host_find_failed = defer
no_more
Now we need to create a new email “transport” to rely on mailjet for sending (aka be our middle man), search for “begin transports” and add the following…paste my code and make sure to edit “in-v3.mailjet.com” with the server where your mailjet account got provisioned
mailjet_smtp:
driver = smtp
hosts = in-v3.mailjet.com
hosts_require_auth = <; $host_address
hosts_require_tls = <; $host_address
Now its time to restart exim to load the changes. Restart the service, on CentOS 7.3 the command would be
# systemctl restart exim.service
If you correctly followed the directions, adding the 3 needed sections to exim.conf and restarted the service now you should be able to try sending yourself a test email. You can do so from the command line like so:
# echo "Subject: desantolo rocks!" | sendmail -v [email protected]
The “-v” will make this transaction be verbose so you can troubleshoot it. You should see a successful email send to the mail relay mailjet server. Important: the email will not be in your inbox yet! You have to approve the sender (the email most likely was sent from [email protected]). I won’t get into the details of how to whitelist because on your mailjet.com dashboard you will see an error message that will say the same thing and point you to their documentation that is simple enough to follow to get your sender whitelisted (in this case [email protected])

Turn Off Windows firewall in rescue mode using VNC viewer
-----------------------
Ref Link: https://mysuperweb.co.uk/server/windows-firewall/
The first step is to load up CMD-Line, from here we will load up the server registry.
reg load HKLM\Win_SYSTEM C:\windows\system32\config\system
Afterwards we can edit the registry by running the command of regedit.
The firewall setting is located at:
\HKEY_LOCAL_MACHINE\Win_SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\PublicProfile
In our example our path is set on ControlSet001. Its possible that you may have multiple ControlSet and it might be different values. This is dependent on your environment.
Here we can see a file called EnableFirewall The current value is 1, we will be looking to change the value into 0.
reg unload HKLM\Win_SYSTEM
