linux port 427 svrloc?

Good day experts

I'm currently running a Linux SLES 10 SP3 on my server, and closing some unused ports because this one is going to production environment soon.

I nmap'd my server to discover some ports, and there's a

427 tcp svrloc

Looking at /etc/services, it says it's a "Server Location" service. Right now this line is commented from the /etc/services, but this port is currently listening.

I have the following questions:
1 Is this port needed to be open? If not, which services would be affected if closed.
2 How do I close this? /etc/services has commented this line, so I guess that there's a daemon elsewhere opening it, but, how do I disable it?

Thnks in advance

/etc/services is not a method to use to stop services binding to ports.  I suggest reverting any changes you made to that file, you should never need to touch it.

If you are asking if you need to run SLPD, then you most likely do not.  Read the following links to help understand what SLP does.

Check to see if the slpd service is running.  If it is, stop it and disable it from running at boot with chkconfig.

Do you not have a network firewall in your environment?  Generally there is little need, if any, to firewall on your internal hosts.
