Go ahead and manually delete links in the /etc/rcN.d directories. I don't think the update-rc.d command adds enough functionality to warrant learning about it, so why use it (aside from within a package's installation scripts). Keep inetd (InterNETDaemon), aside from browsing the web, some progs use a daemon-client model, this means you also want portmap; lpd is the LinePrinterDaemon, you probably want to keep it (needs inetd to work, IIRC); sysklog is the System and Kernel LOGging daemon, definately keep it running (but you may want to configure logging to be less redundant, see /etc/syslog.conf); NetworkFileSystem can go if you don't mount directories on a network. I suggest you play with one of the rcN.d dirs (not the default runlevel, rc2.d, unless you changed it in /etc/inittab) and see what happens. At worst you will need to reboot. "man telinit" should get you started. The files in init.d are scripts; you can look at them and see what they are doing, no need to blindly disable stuff unless you are adventurous. Run levels can be a powerful tool, especially if you want or need to get the best performance from your machine. I have set runlevels for: general use; optimized for compiling; optimized for X; one that is untouched; and another that is not much better than single user mode. It makes a big difference on this old and slow box (486-25), but I guess that depends on the system you are running and why you want to disable the daemons and setup scripts. If you are thinking of security issues, you should look at the /etc/services file. > any insights would be appreciated. Hope that helps. - Bruce
