Disabling Services

[Mike Waibel]

What is the easiest way to disable services?
SNMP, Tooltalk, RPC nlockmgr, RPC llockmgr.



Is there a way to tell if these services are running?

Hi Mike,

You need to look into /sbin/init.d/ for these services. To stop, # /sbin/init.d/ stop

Thanks...

How do I keep them from running when I reboot the machine?

In /etc/rc.config.d/*
you will find config files, and toggle variables defined in this files (0,1) to make them start at boot.
In /etc/rc.config.d/netdaemons you'll find net services and also look at /etc/inetd.conf where basics net services are configured.

Regards.

To disable a net service defined in /etc/inetd.conf simple comment its line with a "#".

Hi Mike,

You need to edit /etc/rc2.d/ or /etc/rc.config.d/ and make it disable from reboot.

Thanks again!!!

I have more questions--

What, if anything, does the /etc/services file have to do with services running?

And will disabling the services at startup prevent applications or users from invoking them later. I want to totally disable this stuff.

perhaps, you can delete lines in /etc/rpc file that show that services.

/etc/services simply map a port to a name, better to understand.
i.e. the system will refer to the name instead to the port number if it is present in /etc/services:

netstat -a | grep LIST | tail -1
tcp 0 0 *.smtp *.* LISTEN

Now with -n options you see the actual port number:
tcp 0 0 *.25 *.* LISTEN

As long the user is a normal user, he cannot start any of the system processes / services.
