Yes

That is probably the mystery third file that NM has mangled.  I can't get at 
the box immediately to check.  For when I do (and googling does indeed 
suggest that NM is probably interfering or has interfered), what should it 
look like?  I have never needed to edit it before.

Googling further suggests that /etc/init.d/networking and /etc/init.d may have 
been altered and may need putting back to where they were.  So I would be 
very grateful if one of you felt able to post specimens of known-working 
versions of these files.

And I have decided that, whatever the cost, I am going to purge that wretched 
NM.  Then, once I have corrected the files, they will stay corrected.

Thanks for the help.
