Permission error when WebLogic Server starts up

Question

Dear WebLogic gurus
When I try to startup WebLogic server with 80 listening port in Solaris 2.6,
it did not startup due to permission problem.
The error log said that
Sat Dec 11 06:11:02 GMT 1999:<E> <ListenThread> **** Unable to create server
socket. Perhaps another process is using port 80.
Sat Dec 11 06:11:02 GMT 1999:<E> <ListenThread> java.net.BindException:
Permission denied
To solve this problem, I just tried to startup WebLogic with root user
because I was sure that another process did not run with port 80.
It works now but with only super user. This kind of problems did not happen
with 7001 port.
What's the reason of this ?
Thanks in advance

Hi there.. Looking at your error, it appears that you there is a web server
already running and bound to port 80. Check with your system admins to see if
you have a web server installed on port 80. Another easy way to figure out
would be a simple telnet to your server name at port 80. Try this:
$ telnet localhost (or servername) 80
GET / HTTP/1.0
If that works any returns any data, you've got a webserver running at port 80.
Work with your system admin's to turn off that running webserver and picking
another port for WebLogic.
Under UNIX, anything under port 1024 is considered a privileged port and root
would have to start the server to be able to bind to port 80. You'll also want
to enable the setUID program in weblogic.properties. Look for the following
lines in your weblogic.properties and see if they apply.
# UNIX only: If running on port 80 on UNIX, enable the setUID program
#weblogic.system.enableSetUID=false
# UNIX only: Unprivileged user to setUID to after starting up
# WebLogic Server on port 80
#weblogic.system.nonPrivUser=nobody
Hope this helps.
