will this be o.k. to do
 

If I am not using send mail or ssh I would like to stop those services. Can I just comment out these two shell scripts in my /etc/rc.d directory. the two scripts are called rc.sendmail and rc.sshd ? is this a sensible way of doing it?

That's what I did. :) (Chmod'ed them, I mean. You'd have to 'comment them out' in the scripts in rc.d, but you can disable them with chmod, of course.) You can chmod others and comment stuff out in inetd.conf, too.

I decided to chmod them it worked nice. Now my only listeming port is 6000. I could boot into runlevel three and startx-- -nolisten tcp. But I boot into X directly, so I am haveing a little more trouble getting that to work. Tried some differnt things but they messed some stuff up.

Yeah - I guess start out at the x/g/k-dm man pages and follow it out from there. If you were using xdm, since startx is just a wrapper to X, I think you could just append the option to the 'X' line in /etc/X11/xdm/Xservers, and it's probably something similar for gdm/kdm. I don't use runlevel 4, though, so I'm not real familiar with the ?dm's.
