Restart of services if port no is changed in /etc/services in RHEL

I had a doubt if any services need to be restarted if port no in /etc/services in an RHEL setup is changed. For eg, the port no of 443 for SSL may need to be changed.

I hope my query is clear whether any services need to be restarted if port no in /etc/services is changed.

Please revert with the reply to my query

Regards

/etc/services is not a configuration file. Changing port numbers in it isn't likely to do anything except mislabel your netstat listings.

Thanks Corona688 for your answer. But, my question is how to change port of SSL which is 443 by default.

Also, can you please clarify with the help of an example how changing /etc/services is going to mislabel the netstat listings?

You need to replace the port 443 with an unused port in your Apache configurations (If using Apache as web-server) and do a httpd restart.

Changes in /etc/services may not require any other services restart.

Thanks for your answer but how to change the port for SSL, is it from the SSL configuration file ssl.conf found in /etc/httpd/conf.d/ssl.conf?

Yes, look for the port 443 entries and alter to the desired port. Always keep a conf backup before any changes.

netstat will label connections 'http', 'ssh' and so forth matching common port numbers given in /etc/services, which is just a list of traditionally used port numbers. Give it wrong numbers, and netstat will label the wrong things.
