This command shows the total count of directories and files within a specified directory:

ls -1R directory/ | wc -l

When accessing /wp-admin a blank screen appears. The fix that worked for me was the following:

1. Backup current web files and database

2. Download a copy of WordPress from wordpress.com

3. Upload and overwrite website files with blank copy downloaded above

*NOTE – this will not overwrite your theme and settings

4. Refresh site and update database if required (prompted on screen)

5. Done!

I believe this issue was caused by an auto update of WordPress although not confirmed.

Received this error when trying to dump a database:

mysqldump: Got error: 1449: The user specified as a definer ('root'@'localhost') does not exist when using LOCK TABLES

To dump out the database run the following:

mysqldump --single-transaction -u username -p db > db.sql

That’s it!

*This tutorial assumes that you already have Smoothwall Express 3.1 installed on your hardware of choice.

With BT Infinity becoming evermore available we decided to setup and test smoothwall as our Firewall of choice. After quite a bit of head scratching we were able to get things up and running.

Once you have Smoothwall up and running access the web interface (https and port 441 – http://x.x.x.x:441) and navigate to Network > Interfaces:

Here, simply select the PPPoE as the ‘Connection method:” and save. Now navigate to Network > ppp:

Here we enter a Profile name, BT username and password and the authentication method. Above is an example of the settings we used for our BT Infinity test line.

Now navigate to Control > Home and click connect. If everything has been entered correctly you should have a Firewall protected BT Infinity line. Enjoy.

Few things to note:

• Cat 5 from white modem to smoothwall red interface
• Cat 5 from green interface into your switch or machine
• Firewall > Outgoing > Make sure 80, 443 etc. are open so you can access the outside world from behind the Firewall.

Pre-reqs

Update and Upgrade Debian. Install bzip2.

apt-get update
apt-get upgrade
apt-get install bzip2

Install iRedmail

wget http://bitbucket.org/zhb/iredmail/downloads/iRedMail-0.8.7.tar.bz2 --no-check-certificate

tar xjf iRedMail-0.8.7.tar.bz2

cd iRedMail-0.8.7

bash iRedMail.sh

**NOTE – bash script will install everything including MySQL, postfix, roundcube etc.

A series of prompts will be presented. Answer as follows:

1. Welcome and thanks for use-  Click Yes
2. Specify location to store all mailboxes. Default is /var/vmail/
3. Choose backend used to store mail accounts. Please choose the one which you’re familiar with – MySQL is my preference
4. Set password of MySQL root user. MySQL is used to store data of other applications, e.g. Roundcube webmail, Policyd, Amavisd-new.
5. Add your first mail domain name : example.com – only supply domain not the FQDN at this stage
6. Set password of admin account of your first mail domain.
7. Choose optional components : [Select All and press Next…]
8. Setup will ask for iptables config and restart the firewall
9. Reboot

Login to iRedmail:

* URLs of installed web applications:
*
* – Webmail: httpS://servername.com/mail/ or httpS://x.x.x.x/mail (IP)
* – Admin Panel (iRedAdmin): httpS://servername.com/iredadmin/ or httpS://x.x.x.x/iredadmin (IP)
* + Username: postmaster@example.com (mail domain name specified), Password: **********

All of the above information is emailed to the postmaster account and shown on screen. Take note.

That should be iRedmail up and running.
