Re: EMC - now getting desperate!

Hi all,

Thanks for the replies, especially Matt - I didn't realise there was a
linux users group so near at hand, I'm certainly going to try to follow
that up tonight. For your info Sheffield is pretty much in the exact
centre of Britain - draw a horizontal line along the top edge of Wales
and continue it across England and we are about half way across the
country, right on the border between Derbyshire and Yorkshire. Having
said that we are in the centre of the country, however, we are always
considered to be a 'Northern city' but I guess this is just because the
poor peasants of London never dared venture far and risk tangling with
those ruffians 'up north'.

Jon,
this is the syntax I have been using and now, whatever script I try to
run from the emc directory, I am getting the 'no such file or directory'
message. When I first loaded emc and tried to run scripts I always got a
'you do not have permission to access this file' message and so I did a
'chmod 777' to the script file and tried again. This then gave the 'no
such file....' message and I can't understand why. I thought that 'chmod
777' basically just changed the permissions on a file to make it
accessible to everyone - instead it seems to have hidden them from the
execute command in some way.

No the script is calling for steppermod from this location and I haven't
even done any modification to the permissions on this file or anything
else.

This is a good idea which hadn't occurred to me and I will try it later
this evening. I am running as 'root'. I don't understand the last bit
about giving kernel modules root priveledges and pre-installing them.

Thanks everyone

Best wishes
