Thursday and friday i will be at Reboot 9 – it’s the third time I attend – last time was two years ago, and the first time was actually at the first Reboot conference – pre-bubble, y2k and all. This years theme is “Human”. The focus is rarely technology, but future ways of thinking and working. This year one of the headliners are Dave Winer – a talk on friday I will forward to. I also expect this to be another great networking opportunity.
I was annoyed – but not anymore. I have been developing for Apache/MySQL on my laptop for a while, and in the beginning I would start the Apache and MySQL services automatically as I booted Windows. Recently I embarked to minimize the boot time of my Windows installation – and that included minimizing the services starting automatically – including Apache and MySQL. To start these two services, I enabled the System Tray icons for the two services and when I wanted to start the services I would right click the MySQL monitor and choose “Start instance”, and then left-click the Apache icon and click “Start” in the submenu.
This seems fairly simple, but if you try to navigate icons in the System Tray before everything is done loading, you will know that right-clicking something may give long delays, sometimes sub-menues disapear and you don’t know if it was because of your click, which it did not respond to or if your click was actually registered. So the tip is simple and low tech – perform the same thing in a .bat file:
net start mysql
net start apache2
net stop apache2
net stop mysql
Put these on your desktop or quickstart menu..
Dive into the possibilities of Microformats from this article at Smashing Magazine. The article points out a few simple additions for your website, that will easily add context to the contents of your site to humans and machines.
An example: If you are selling something, specific crawlers of trade sites will know it as they find the appropriate microformat code on your site. Another example: Make your resume available in hResume format embedded in your regular HTML code and it can be indexed by recruiting companies.

Up until today, I have had to make important files from the shares of my home Linux server available as Windows Offline files to have them readily available on the road. I could sftp to my home server and fetch the files, but with the overhead of having to remember to actively upload the files again if they have been updated. I had a hunch that SSH tunnels could help me out, but today I finally made everything work, enabling me to map drives to the Samba shares of my home server through a secure SSH tunnel. Here’s how..
I am creating this setup using my home Linux server connected to my ADSL connection at home. I want to connect my laptop to my Linux server in order to map the Samba shares as drives on my laptop, when I am connected to the internet at the office or at a client. The Linux server is running OpenSSH which enables me to make regular SSH terminal connections using a client such as Putty, SFTP file transfers using WinSCP AND tunnels – also using Putty.
A tunnel through SSH works like this: A service is listening for connection requests on some port on the server -A Samba server listens on port 139 (like any Windows machine that has “File and printer sharing” installed does). When you create a tunnel like this one, you are “rewiring” the network of your workstation telling it to forward all connection attempts to the local port 139 to port 139 of the remote server through a the secure connection supplied by SSH. As only one service can listen on one port at a time, you need to uninstall “File and printer sharing” for your network connections. Please note that when you do this, any folder or printer shared by your computer will no longer be available to other users on your network.
If you have Samba shares and OpenSSH running on your server and you can connect to it using an SSH client, you only need to change the setup of your client pc.
- Install Putty – which should be fairly straight forward.
Uninstall “File and Printer sharing”. Note: If you merely disable the element, this will not work as the service will still listen on port 139 and block Putty from listening on the same port. A complete Uninstall is necessary.
- If you already have a terminal connection set up for your server in Putty, it can be reused and you can merely add a tunnel to the connection. To make your initial connection in Putty, simply supply your internet IP address (or domain name if you have one) for your home server, and make sure the standard port 22 is NAT’ed in your router to your server. You may choose to increase security by having OpenSSH run on a port other than 22 – but that is a outside the scope of this post.
- Open the Tunnels configuration and enter:
- 139 in the Source port field
- The internal IP adress of your server followed by :139 to indicate that you wish to connect to port 139 on the server. In the example below, the internal IP adress of the server is 10.0.0.150
Apply your changes and open the connection. Once you have succesfully logged on in the terminal window the tunnel will be established and you should be able to start mapping drives to \\127.0.0.1\remotesharenames.
