Customise WordPress Dashboard for Clients

To keep your clients from risky places or to restrict access to specific pages from the clients, you can customise your WordPress dashboard by adding the below code in your theme’s functions.php. This code allows you to hide parts of the WordPress dashboard menu.

You need to uncomment the line ( remove // ) for the page that you want to hide/remove from the WordPress menu.

Be aware that this only hides the menu items from the dashboard and clients can still theoretically access these menus with a direct link (if they know).

How to fix Error 404 when Password Protect a WordPress Subdirectory with .htaccess

When you try to password protect a WordPress subdirectory by adding .htaccess and .htpasswd under subdirectory, you sometimes (in fact most of the times) get Error 404 – Page not found when you visit that subdirectory location in the browser.

To fix this error, add the following line at the top of .htaccess located in the root of your WordPress installation (yes, root .htaccess and not .htaccess of your password protected subdirectory), and you’re good to go now.

ErrorDocument 401 default

Do you have any different solution? I would love to hear your comments.

Amavisd-new, ClamAV and SpamAssassin with Postfix on CentOS 6.7 Server

What is amavisd-new, ClamAV and SpamAssassin?

amavisd-new is a high-performance interface between mailer (MTA) and content checkers: virus scanners, and/or SpamAssassin.

Clam AntiVirus (ClamAV) is a free and open-source, cross-platform antivirus software toolkit able to detect many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner.

SpamAssassin is a mail filter to identify spam. It is an intelligent email filter which uses a diverse range of tests to identify unsolicited bulk email, more commonly known as Spam.

Installation:

yum install amavisd-new

☑ This will install amavisd-new and a bunch of dependencies. It will also install SpamAssassin by default.

yum install clamav clamav-update

☑ This will install ClamAV.

freshclam

☑ This will update the ClamAV database.

Configuration:

☑ Edit amavisd.conf.

vim /etc/amavisd/amavisd.conf

Change the following lines like this…

$mydomain = ‘domain.com’;   # a convenient default for other settings
$myhostname = 'mail.domain.com’;  # must be a fully-qualified domain name and same as reverse DNS lookup

☑ Make sure everything is set in postfix’s configuration file master.cf

vim /etc/postfix/master.cf

On top of master.cf, you should have something like…

smtp      inet  n       -       n       -       -       smtpd
 -o smtpd_sasl_auth_enable=yes
 -o receive_override_options=no_address_mappings
 -o content_filter=smtp-amavis:127.0.0.1:10024

…and on bottom, you should have something like…

#
# spam/virus section
#
smtp-amavis  unix  -    -       y       -       2       smtp
 -o smtp_data_done_timeout=1200
 -o disable_dns_lookups=yes
 -o smtp_send_xforward_command=yes
127.0.0.1:10025 inet n  -       y       -       -       smtpd
 -o content_filter=
 -o smtpd_helo_restrictions=
 -o smtpd_sender_restrictions=
 -o smtpd_recipient_restrictions=permit_mynetworks,reject
 -o mynetworks=127.0.0.0/8
 -o smtpd_error_sleep_time=0
 -o smtpd_soft_error_limit=1001
 -o smtpd_hard_error_limit=1000
 -o receive_override_options=no_header_body_checks
 -o smtpd_helo_required=no
 -o smtpd_client_restrictions=
 -o smtpd_restriction_classes=
 -o disable_vrfy_command=no
 -o strict_rfc821_envelopes=yes

☑ Stop the postfix daemon.

service postfix stop

☑ Start Spamassassin, Amavisd-new and ClamAV daemons.

service spamassassin start
service amavisd start # This will also start ClamAV

☑ Start the postfix daemon.

service postfix start

That’s it! Now you have a basic spam and virus protection up and running on your CentOS server. ?
