Hi Guys,

I am using ubuntu and having nginx with thin (using sockets) and rails  
successfully — only on port 3000 and 3080.

When I try to change the nginx config and  
listen 80;

it fails and the follows found in nginx/error.log

2010/01/04 21:08:25 [emerg] 21146#0: bind() to 0.0.0.0:80 failed (13:  
Permission denied)

And I’ve checked what binding on port 80 but failed:

arthur@ubuntuserver:~$ sudo netstat -plant | grep ‘:80’  
[sudo] password for arthur:  
tcp 0 0 0.0.0.0:8000 0.0.0.0:\*  
LISTEN 21395/with\_thin.con  
tcp 0 0 0.0.0.0:8025 0.0.0.0:\*  
LISTEN 2999/master  
tcp6 0 0 :::8025 :::\*  
LISTEN 2999/master  
arthur@ubuntuserver:~$ lsof -i tcp:80  
arthur@ubuntuserver:~$ lsof -i tcp:8080

Can you help me?

Thanks a bunch!  
Arthur

you have to start it as root, users don’t have privs to open ports below  
1024
