Revision as of 21:50, 15 April 2010
For those using ZCS 5.0.16 and prior, come 15 April 2010 anti-virus definitions will no longer update AND your ClamAV instance will stop working entirely.
Zimbra includes ClamAV 0.95 as of ZCS 5.0.18+. The clamav-0.95.1 directory from an installed ZCS 5.0.18 or later installation can be copied directly to an earlier ZCS 5.0 server. To upgrade ClamAV, perform the following steps:
Update: For linux we've made this available at http://files2.zimbra.com/downloads/clamav/clamav-0.95.1.tar
1. Install a new server with a later release of ZCS. The Free Open-Source release of ZCS is available at http://www.zimbra.com/downloads/os-downloads.html. This document was tested with 5.0.21, but any release starting with 5.0.18 or later will work. 2. After the installation is complete, tar up clamav-0.95.1 on the new server:
cd /opt/zimbra tar cf /tmp/clamav-0.95.1.tar clamav-0.95.1
3. Copy this tar file to your existing ZCS server.
cd /opt/zimbra scp user@server:/tmp/clamav-0.95.1.tar .
4. Untar the file.
tar xf clamav-0.95.1.tar
5. Stop ZCS services.
6. Change the symbolic link
ln -s clamav-0.95.1 clamav ls -l clamav
The output line will look similar to:
lrwxrwxrwx 1 root root 25 Apr 9 15:39 clamav -> /opt/zimbra/clamav-0.95.1
7. Start services.
You can confirm that the new version of ClamAV is running by checking /opt/zimbra/log/clamd.log. The most recent startup in the log should look similar to:
Fri Apr 9 15:57:16 2010 -> +++ Started at Fri Apr 9 15:57:16 2010 Fri Apr 9 15:57:16 2010 -> clamd daemon 0.95.1-broken-compiler (OS: linux-gnu, ARCH: i386, CPU: i686)
With ClamAV 0.95 in place, updates should continue uninterrupted after April 15, 2010, and your system will remain protected.
This procedure was tested using ZCS 5.0.21 and ZCS 5.0.7.
