But, would changing the SSL port in /etc/httpd/conf.d/ssl.conf also change the port in /etc/services? Also, will the netstat command take the ports nos from the actual port in the respective configuration file or from /etc/services?

Confirmations on these queries will reaffirm the understandings.

You must edit the /etc/services conf manually to update the new port.

In Unix /etc/services file maps port numbers to named services which uses by netstat.

Maybe I'm missing something here, but I don't recall seeing "why" you are wanting to change the default SSL port. Do you have an app that is trying to use this port for some other reason?

My suggestion is to change w/e other software is wanting this port so as not to conflict with a standard port setting.

Regards,

No, it would not... /etc/services is a list of traditional port numbers. It's used to label label outgoing connections, too, so altering it will mislabel anything you connect to on standard ports.

If you moved your https port onto a number not specified in /etc/services, it would just show as a port number in netstat. If you moved it to the same port as some other service, it would show as the wrong service in netstat, because you intentionally made the choice to move it onto a nonstandard port. You shouldn't edit /etc/services to fix that, simply remember what you did.
