Fatal error: Call to undefined function mb_strtolower() on cPanel server
I was facing following error on my site :
=======================================================
Fatal error: Call to undefined function mb_strtolower() in

Error connecting to MySQL: Access denied for user: ‘da_admin@localhost’ (Using password: YES):
Today When connecting to the MySQL in DirectAdmin , I got this error
and that would indicated that the “da_admin” user has not been setup
correctly. To resolve this I did following:
1) You need to Make sure the root mysql password works. If you know it, Go to mysql, If you don’t.. then mysql root password can be found in the /usr/local/directadmin/scripts/setup.txt , if it has not been deleted.
It’s under the header “mysql=”.
If it cannot be found, then mysqld will have to be restarted with the –skip-grant-tables option as follows :
==========================================
# [root@test ~]# service mysqld stop
# [root@test ~]# mysqld_safe –skip-grant-tables &
===========================================
This will start up mysql without the need for a root password. Then run

Securing PHP
Now a days PHP is an essential part of Web Develop environment, so try to secure from a System Admin’s perspective.
Hardening with php.ini
1) open_basedir = /dir
When the open_basedir parameter is enabled, PHP will be able to access only those files, which are placed in the specified directories
2) expose_php = Off
Turning off the “expose_php” parameter causes that PHP will not disclose information about itself in HTTP headers that are being sent to clients in responses to web requests.
3) register_globals = Off

HOW-TO: finding “Nobody” spammer
In this script we will change the sendmail binary with a custom script, because php is using the sendmail to send the mails through script. So the spammer is calling this script instead, which is then logging the user info into a log file before calling the now renamed sendmail.
After installation check /var/log/formmail.log to find spammer activity.
Installation:
Note:- Place take a backup before moving the file to prevent any sort of data loss issue.
mv /usr/sbin/sendmail /usr/sbin/sendmail.act
vim /usr/sbin/sendmail (paste the below code into it)
chmod +x /usr/sbin/sendmail
echo > /var/log/formmail.log
chmod 777 /var/log/formmail.log
After installation check /var/log/formmail.log to find spammer activity.

Using “imapcopy” to transfer the mails
MAPcopy is a small utility that will help you migrate from one IMAP e-mail message store to a another one.
1) wget http://home.arcor.de/armin.diehl/imapcopy/imapcopy.tar.gz
2) tar -xzvf imapcopy.tar.gz
3) cd imapcopy
4) Edit the file “ImapCopy.cfg”
Adjust the source and destination server. Add the source and destination users and passwords. The following sample copys the users “foo” and “bar” from server source.imap.com port 143 to server dest.imap.com port 145. Passwords for foo are “foosrcpw” and “foodestpw”, for bar “barsrcpw” and “bardstpw”. The folders “Trash”, “Sent” and “Sent Objects” will not be copied.
SourceServer source.imap.com
SourcePort 143
DestServer dest.imap.com
DestPort 145
#CreateEmptyFolders
skipfolder INBOX.Trash
skipfolder INBOX.Sent
skipfolder "INBOX.Sent Objects"
# SourceUser SourcePassword DestinationUser DestinationPassword
Copy "foo" "foosrcpw" "foo" "foodestpw"
Copy "bar" "barsrcpw" "bar" "bardestpw"
Now verify that all users and passwords are correct:
imapcopy -t
You can also show some information about the used servers:
imapcopy -i
You can copy the mails as:

1) wget http://home.arcor.de/armin.diehl/imapcopy/imapcopy.tar.gz
2) tar -xzvf imapcopy.tar.gz
3) cd imapcopy
4) Edit the file “ImapCopy.cfg”
Adjust the source and destination server. Add the source and destination users and passwords. The following sample copys the users “foo” and “bar” from server source.imap.com port 143 to server dest.imap.com port 145. Passwords for foo are “foosrcpw” and “foodestpw”, for bar “barsrcpw” and “bardstpw”. The folders “Trash”, “Sent” and “Sent Objects” will not be copied.

Phpmyadmin error : “The Configuration File Now Needs A Secret Passphrase (blowfish_secret)”
After installing phpmyadmin on one of my client server (Centos), I
had to face above error after login into phpmyadmin at the bottom of the
phpmyadmin page.
Error :
====================================================
”The Configuration File Now Needs A Secret Passphrase (blowfish_secret)”
====================================================
I tried this Soution which resolved the issue :
Solution :
Copy sample Configuration File To Real Configuration File:
# cp -p config.sample.inc.php config.inc.php
If you have already copied the file just locate it and go to the file :
#vi config.inc.php
Find the below line :
===========================================================
$cfg['blowfish_secret'] ’ ‘; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
===========================================================
Probably on the line number 16 or 18.
You can see its not set, so you need to update the Blowfish Secret here.
After doing this, Try to visit your phpmyadmin url again and you will see the error is disappeared.
Njoy!!!

Differences between TCP and UDP Protocol
If you want to know the exact difference between TCP and UDP protocol, lets have a look below :
Firstly, What is TCP and UDP protocol :
Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are the major protocols operating at Transport Layer. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) operate very differently and you can choose Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) depending on your requirement.
1. TCP Protocol : TCP stands for Transmission Control Protocol and it guarantees delivery of data packets. This protocol provides extensive error checking mechanisms such as flow control and acknowledgment of data. Transmission Control Protocol (TCP) is a connection oriented protocol. Before transmitting data, a connection must be established between the devices participating in data transmission. If your Application require guaranteed delivery of data, then you must choose TCP as the Transport layer protocol.
2. UDP Protocol : UDP stands for User Datagram protocol and it operates in Datagram mode. The main difference you should notice here is User Datagram Protocol (UDP) is a connection-less protocol. User Datagram protocol (UDP) has only the basic error checking mechanism using checksums.
Now I assume that you under stand what is TCP and UDP protocol more than there long forms Now see Difference between Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) below :

Correcting ownership of all cPanel Users
If you have messed up with the ownership of all the users on a cPanel
server, following script will help you to correct the ownership:
====================================
# Login to server as a root
# create a shell script and enter the code below :
# vi permissions.sh
Code to be entered :
====================
for i in `cat /etc/trueuserdomains | awk ‘{print $2}’`
do
/bin/chown $i.$i /home/$i -R;
/bin/chown $i.mail /home/$i/etc -R;
/bin/chown $i.nobody /home/$i/public_html;
done;
====================
Save the file and change the permission for the file permissions.
# chmod 755 permissions.sh
Then run the script.
# ./permissions.sh
It will take some time according to the amount of users and The ownership of the home directory of a user, etc and public_tml will be corrected in a one go.
