Update of /etc/services

[Yogeeraj]

Dear HP Experts,

Please advise.
We have setup a suite of Oracle Products recently.
We had been advise to enter the details of all port numbers used in the operating system file: /etc/services.

Could you please advise on how to enter the details.
For example,
Oracle Management server accepting requests on port numbers 7771, 7772, 7773
Oracle Enterprise Java Engine TNS Listener accepting TCP/IP requests on port 1521 and IIOP: 2481
Oracle HTTP Server (apache, which is also listening on port80) - 7777


thank you for a reply

Kind regards
Yogeeraj

The /etc/services file is a mapping of port numbers to service name and as such, if the application does not use the port name, i.e. do a getserv*() system calls, then there is no need to update the /etc/services file.

That said, typical services entries are of the form:

SERVNAME PORT/PROTO

where SERVNAME is the service name, could be anything you want. For example the service name for 80 is http, and for 23 is telnet.
PORT is the port number and PROTO is the protocol being used, i.e. tcp or udp.

Btw, port 80 should already be defined in the services file.

Hope this helps.

I would simply add them in as thus;

OMS 7771/tcp # Oracle Management Server
OMS 7772/tcp # Oracle Management Server
OMS 7773/tcp # Oracle Management Server
OEJE 1521/tcp # Oracle Enterprise Java Engine
IIOP 2481/tcp # Oracle Enterprise Java Engine
Oracle_http 7777/tcp # Oracle HTTP Server
Apache 80/tcp # Apache http server

Hi cmt,
I agree with Stefan, U can add a new port through using vi /etc/services.
