Hi Parv:
And also thanks to the other people who responded earlier. I did not
knowingly set up automounter - is this something I would have had to do?
or part of a default install?
I am still hoping that somebody can tell me what /net and /host are -
inted? samba??
Thanks again.

btw: My previous send seems to have bounced...
It read:
Hmmm. My system is 4.11 so that would explain /proc. Could /net and
/host be related to running apache or samba? I did not knowingly create
these "devices" I haven't been as vigilant as I could have been for
security (one of my reasons for an upcoming reinstall), so there is a
possibility of the server being hijacked...? But I don't want to assume
the worst on false concersns..
