During development of our rails application, I went through the initial try/error phase. But it seems that there is always space for new problems.

I have been testing the HTTPS, so I run the WEBrick servers on standard ports 80 and 443 and the WEBrick server went down immediatelly with a strange error:

I am pretty sure I didn’t runn any web server on my machine. Fortunately I have Unix tools on my Windows machine and netstat -a -b gave me a good hint.

Skype occupies these standard ports! So, if you need to test your rails application on a standard port, just shut down Skype. Do not forget to turn Skype on afterwards. It is a great tool.
