Shalom RK,

Normally you would not need to restart the daemon.

As far as what daemon, you would need to know what service/daemon you are trying to enable.

It can't hurt to stop/start the daemon.

RK,

The /etc/services file is used to keep the entries of the ports used on the system so as to directly co-relate a particular port number to a service for an application. This is more like a look-up or reference file rather than a configuration file, hence you can do away without restarting the service.

Hope this clarifies,
Ninad

Hi,

Direct answer to the question is "NO". But it all depend on this port is used for which application or what daemon. /etc/services file will keep all the port numbers and applications or processes will pick this information when they are initiated. So in brief, If you want any process to pick up this new port number, then you may need to restart that.

Hi,

if you use NIS for name resolution
(check via
grep services /etc/nsswitch.conf
) , you must rebuild the corresponding maps (services.byservicename, services.byname).

A restart of any service is not required - the name-to-port resolution is done when getservbyname() (or similar) ist called by your application program.
