"port concept" isn't specific to hp-ux. 10 seconds with google found this general info regarding ports and some of the widely used port numbers

Hi Gurus,
Thanks for your valuable reply.

The links provided by you are very much helpful.

I got my port number for a particular service

more /etc/services | grep -i ftp

the port was 20 for ftp.



Thanks a lot again.

Hello Sree,

Take a look on the below URL:

Ports are ports, and are not limited to hpunix but are there whenever you talk about Networking.

Hit for "Socket Programming" in google and top threads will have some more info for you which may interest you.


Cheers!!
