Why does Tomcat work with port 8080 but not 80?

Question

I have started and tested Tomcat under Port 8080 (default). Now I altered the connector port to 80 and restarted Tomcat, nothing will show on my minimal Debian 6.0 installa

Answer 1

go to /etc/default/tomcat6 and change #AUTHBIND=no to AUTHBIND=yes

 # If you run Tomcat on port numbers that are all higher than 1023, then you
 # do not need authbind.  It is used for binding Tomcat to lower port numbers.
 # NOTE: authbind works only with IPv4.  Do not enable it when using IPv6.
 # (yes/no, default: no)
 #AUTHBIND=no
