April 21st 2006 at 11:14 am in So, the mail-server is scanning incoming and outgoing email for virusses using the McAfee command line virus scanner for Linux.
Today I found out I was getting loads of reports in my email, though:
Scanning could not be performed due to the following error:
Missing or invalid DAT
WTF? The file’s there and looks OK. Re-downloading it didn’t seem to have any effect either.
Of course, I searched a bit and although I found a few guys with the same problem, I didn’t really find a solution.
So I looked around a bit and — d’oh! — found out that, when I last modified the system, I made a little error there.
See, usually I install additional software on another partition, but the first installation of the virusscanner had thrown some libraries in /usr/lib/. Lacking an entry in my /etc/ld.so.conf file pointing to the newer library files installed by the latest scanning-engine, the uvscan-binary was starting up loading the old-library.
Yeh, sure it’ll find the DAT is invalid if major engine changes have taken place. Nothing weird about that at all.
