Subject [Httpd Wiki] Update of "CouldNotBindToAddress" by preaction
Date Sat, 11 Jun 2011 19:39:44 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The "CouldNotBindToAddress" page has been changed by preaction:
http://wiki.apache.org/httpd/CouldNotBindToAddress?action=diff&rev1=11&rev2=12

Comment:
clarify the reason for conflicting listen directives

  Listen *:80
  Listen 1.2.3.4:80
  }}}
- will incur the same error message. This can be remedied by disambiguating the ip/port numbers.
+ will incur the same error message. Apache binds to *:80, and then tries to also bind on
1.2.3.4:80, which fails because it is already bound by the first line. If you're binding on
*:PORT, you do not need to also bind on a specific IP. 
  
  === You're not root ===
  Unix based systems disallow non-root users to bind processes to port numbers below 1024.
Get root!
