tcp services

ssudhir — Fri, 17 Jan 2003 12:37:16 GMT

Hi all

I am having a L 1000 running hp-unix 11.00 on it. i am trying to start oracle in it. And i am using port 80 for my listener process.which is supposed to be used by http.

i hv disable the port for http by putting '#' in /etc/services.

i am getting problem while starting the listener process.when i check the log its giving port binding error.

Now is there any way to know whether the http services is really stoped or not/and any way to know what are the services started in which port ?

thanks in advance.

regards
S.Sudhir

Hi,

run 'rpcinfo' to check which services the listener is looking for.

To know what are the services started in which port you must to do:
lsof -i :
By example:
lsof -i tcp:80

Hi sudhir

#ps -aef|grep -i http
shows the http processes if running.

to find which port it is using, advise you to use lsof.

The general approach to look for the state of sockets is netstat -a[n].

What kind of error do your get? EACCESS/Permission denied? Port 80 is normally a protected socket, only for root access.

Hi Sudhir,

Commenting out a service port in /etc/services
will not disable the port.

Only way to free a used port is to stop the service using that port. In your case , it is the webserver.

#netstat -an | more

you will see port 80 in LISTENING state with your servers IP address. That means your webservice is listening in that 80 port.

#ps -ef | grep http

Kill gracefully all the running httpd instances.

Start oracle now. your problem is solved.

netstat -an to see if there's 80 listening.
But it's not recommended to run oracle listener on port 80(you'd better run it on a port more than 1024)
