well, I understand that your admin upgraded nethservice to SME (which are "cousins"), IOW, he did not make a fresh install from the bare metal..
if so, you have a mess
is mech the hostname of your SME server?
I want to know if i can ignore this error
we don't know if you can/should ignore it, because we don't know what is running on your server (we don't know either if it is SME or Nethesis and no info on version ecc..)
please report here the output of:
cat /etc/e-smith-release
rpm -qa | grep p3scan
NOTE: no one here can take a look at your screen nor access to your server, so you're our eyes.. if you need help, you must help us to help you, so, please, be "verbose" and give us as much details as you can.. please be specific, because "we upgraded an old Nethsis" is too vague and prone to misunderstanding
