Are you sure you're booting into runlevel 3? The default on most distros is
runlevel 5 (graphical logon mode). Type /sbin/runlevel and check. If you
see something like:

N 5

This means your in runlevel 5 (It's the last number that tells the current
runlevel).

You can also check the runlevel by looking at /etc/inittab and looking for
the line that says:

# The default runlevel is defined here
id:5:initdefault:

If you are runlevel 5 you need to do your above changes to /etc/init.d/rc5.d
not /etc/init.d/rc3.d.

Hi again,
Thanks a lot :), ur solution worked like a charm. I had erroneously thought
that all of the rcX.d scripts run , not only the ones in the same runlevel
ur logging in to. One other question, since the runlevel may be changed
later, to make sure that the services I want are running, should I add the
symbolic link to all the run levels 2 thru 5? No harm in doing that?

Muhammed
PS Thanks again :)

Actually, this is really not a bad assumption. Other versions of Unix *do*
work this way. On Solaris, runlevel 5 means execute the scripts for
runlevels 1,2,3,4 and then 5. So all your network stuff is added to
runlevel3. Runlevel 5 would just start the X stuff and wouldn't have to
bother with the network stuff because it had already been started. On
Linux the runlevels are "orthogonal", and run independently of each other.

Yes, definitely, although practically speaking runlevels 3 and 5 are all
you have to be concerned with (at least that's my experience as I'm just
running a workstation for browsing the web etc).
