The beauty of a simple mv /etc/rc2.d/S23ntp /etc/rc2.d/S53ntp beats all of webmin, for me. On a more serious note, if you know what your distros default run level is, just push the ntp start link to something slightly later than the ppp start link. That is the simplest solution. The way it works, roughly (and totally solution dependant, but most linux distros do it this way these days) is that the kernel boots, and at some point hands thing off to init. init runs all of the scripts that start with S in the rcS.d directory, and then switches to the 'default' run level - what that default is is completely distribution dependant, although I think Redhat-alikes all use 5. Then init runs all scripts in rc5.d directory that begin with an S with the start argument (and really, it should also run all scripts that begin with a K with the stop argument, but many don't). The only real things to know about the hacked SysV init that most linux distros use is that a) scripts whose names start with S should get run with the start argument b) scripts whose names start with K should get run with the stop argument c) All scripts in a directory are run in numerical order d) At boot, S is first, then default run level. That's the basics for managing it. -- -------------------------------------------------------------------------- | Stephen Gran | "Plaese porrf raed." -- Prof. Michael | | steve@lobefin.net | O'Longhlin, S.U.N.Y.
