[Zope] Newbie's Installation: Port number

Hello, I already downloaded Zope-2.0.1-src and sucessfully compiled wo_pcgi.py (Zserver on Red Hat 6.0). When I was trying to run ./start, I got an error 'Address already in use'. According to INSTALL.txt, I should change the port number using 'z2.py -w new_port_number'. My question is what new port number I should fill in. Can it be any port number? How can I know available port number? Thank you S. Prinyanupap prinyanu@hotmail.com ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
