Now all is well in the world of DNS.

Last night I enabled PHP on the apache server built into Mac OSX on my new laptop and installed MySQL on it. I also set up some bash aliases to rsync commands so that I could synchronise the websites from the server to the laptop and back again.

Now that I had local copies of the sites that are synchronised it was time to turn my attention to synchronising the databases between the server and my local machine. I could of configured the server’s MySQL installation to allow remote connections, however, I did not want to do this for security reasons. I decided that I would connect to the MySQL server over SSH by forwarding a port on my local machine to a remote port on the server.

First I needed to create an SSH tunnel using the following command

ssh -fNg -L 3307:127.0.0.1:3306 server.host.name

The options for SSH are

• f
  • Requests SSH to background so that you do not have to keep a terminal connected to the server open
• N
  • Does not execute a remote command (useful for just forwarding ports)
• g
  • Allows remote hosts to connect to local forwarded ports
• L
  • Specifies that a local port (3307) is forwarded to the given host (server.host.name) and port (3306)

I created an alias to that command for easy use in future but I’ll need to make sure the tunnel is active before trying to connect to the remote server.

Next its time to turn our attention to actually connecting to the remote MySQL server.

mysql -h 127.0.0.1 -P 3307 -u username -p

The Options:

• h specifies the host to connect to (must be 127.0.0.1)
• P specifies the port to connect to (your locally forwarded port)
• u specifies the username to connect with
• p will prompt you for your password (–password=passtext can be used to give the password)

Thats if I wanted to connect to the remote MySQL server on the command line. The latest phpmyadmin has an option for syncronizing databases in which case you can put the above details and it will compare the databases and allow you to choose what to synchronise.

To setup root password for first time, use mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWORD

However, if you want to change (or update) a root password, then you need to use following command

$ mysqladmin -u root -p’oldpassword’ password newpass

The appropriate setting can be found under:

System Preferences : Personal > Security > Firewall

I have mine configured to “Set access for specific services and applications” which normally asks me if I want to allow an application to accept incoming connections the first time I run it and that’s normally the end of it. The trouble comes when you try and update certain applications using Software Update. I’m not exactly sure what causes the problem but for some reason with specific applications the firewall then proceeds to ask you, each time, if you would like it to accept incoming network connections. This you can imagine is superlatively tedious.

The answer though is to just delete the application from you applications folder and reinstall it. The first time you open the freshly installed application it will ask the question and then bug you no more. Then all you have to worry about is not updating it via software update again.

that as you are so once was I.

And as I am you too shall be,

prepare ye then to follow me.

Only a breach of criminal law may lead to prosecution. Breach of civil law, however, could well lead to the defendant being sued.

As trespass is a civil offence and not a criminal one then trespassers will most certainly not be prosecuted.

This post is attributed to my brother whom provided the information in the same conversation he tricked me into mis-answering a QI like question. More on that story later.

The way I did it was to have various directories in the /Users/username/Sites directory as is the normal set up but to have a symbolic link for each project that I wanted to have a better looking URL for so for example if my PHP My Admin was contained in the directory /Users/username/Sites/phpma then I would create a symbolic link to the directory /Library/WebServer/Documents/ using the command…

• ln -s /Users/username/Sites/phpma /Library/WebServer/Documents/phpma

Et Voila… I can now use and bookmark a shorter and less visually offensive URL to the sites I’m working on.

Today I’ve been having a conversation with my mother and we were talking about relationships and personality. We’re both of the opinion that its futile to attempt to change yourself in order to please someone else. If only I knew then, what I know now cropped up.

A paradox. The epiphany can never be true. I find in conversation that this phrase usually refers to attitudes and not knowledge. I have now the attitude I do only because of the experiences between then and now so it becomes impossible to ever have the vogue attitude without the requisite experience.

I want to feel your heart beat.
I want to smell your scent, sweet.

Your touch is all I need.
Your attention my only greed.

When all I wanted was for you to stay.
It wasn’t right, now, you’ve gone astray.
