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

[novpenguincne]

To facilitate bandwidth issues, I've set up an internal clam proxy server on SLES15 running the 103.x client. I have successfully connected to it using a different SLES15 box also running the 103.x client and downloaded updates to it.

However, I still have an older SLES11 box running the 98.x client. Due to extenuating circumstances, this box is not a candidate for an o/s upgrade. 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.

When I first attempted, it failed because it was trying to download main.cld which didn't exist on the proxy. 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:

ERROR: During database Load
WARNING: [LibClamAV] cli_ac_addsig: Signature for Win.Backdoor.SystemBC-9885562-0 is too short
ERROR: Failed to load new database: Malformed database
WARNING: Database load exited with status 55
ERROR: Failed to load new database

Do I need to make a change in the freshclam.conf to get this to work? Or is it a matter of the 98.x client unable to read datafiles designed for 103.x clients?
