"Mandrake is famous for the hidden (non-standard) config files.  What you 
may want to look into is where webmin or linuxconf store their files. 
Mandrake may have just written a fancy frontend to either of those 
utilities.  Red Hat and Mandrake both have had problems in the past with 
Gui-based tools not actually altering the standard .conf or config file. 
  You would have a choice of editing by hand (as you did) or by Gui, but 
not both.  MNF is based on Mandrake 7.3 if I recall correctly.  I 
checked it out, but I went for IPCop instead."

So how would I go about finding where webmin and linuxconf store their
files? It seems like if I can find where the GUI is getting its settings I
can just manually configure them and get the GUI and the text files in sync
with each other.
