Raw message 

Ok, it seems the only way we are going to work out the problem, is to 
see what the script is seeing that it thinks is a change in network 
settings.

The script responsible is 
/usr/share/grase/scripts/update_grase_networksettings.sh

Make sure you have your computer setup to email you the results of cron 
jobs (requires a smtp server). Alternatively, install ssmtp and set it 
up to use mail.purewhite.id.au as the smarthost and my tim AT 
grasehotspot.org address as the destination (I think that'll work, email 
me off list before you try that).

Then in the script 
/usr/share/grase/scripts/update_grase_networksettings.sh, find the 
following section and add the one diff line.

Change this part
--
update_new_file() {
     files_equal $1 $2 || {
         cp -f $1 $2
         return 0;
     }
     return 1;
}
--
To look like this
--
update_new_file() {
     files_equal $1 $2 || {
     diff -s $1 $2
         cp -f $1 $2
         return 0;
     }
     return 1;
}
--

Its not well tested, but you should get an email every 5 minutes when 
it's trying to restart the network settings, and it should tell us if 
the 2 files are different or the same, and if they are different, it'll 
show us how. Until I see why it thinks they are different, I'm stumped! 
I attempt to detect server errors and don't restart the services on 
server errors, but maybe I've missed one.
