[clamav-users] using older clients to download from internal clam proxy

[Joel Esler (jesler)]

James,

Thanks for your email.  ClamAV definitions won’t even work on those older versions anymore.  The Flevel for the main.cvd and daily.cvd are now set higher than that, so those systems shouldn’t be able to load the newer definitions.

I also know from CLAM documentation that clients older than 100.x are no longer supported.  But I would still like to have some a/v on this box until its retirement so I was trying to have it download from the proxy server as well.

So I turned off "scripted updates" on both the proxy and the target SLES11 box which is now forcing everything to use cvd files only.  But now when I run freshclam on the SLES11 box, I'm getting different errors.  It downloads the daily.cvd successfully.  Then it tries to load signatures from daily.cvd.  And then I get a sequence of errors:
