If upgrading from anything below 0.90.x, please refer to: *Updating CLAMAV from version lower than 0.90.0
If upgrading from anything below 0.90.x, please refer to: *[[Updating CLAMAV from version lower than 0.90.0]]
To update, follow the following: First go grab the latest ClamAV source from http://www.clamav.net/download  
 
Extract it to where ever you please. All this can either be done as root or as the zimbra user. If you do it all as root make sure you change ownership for the resulting clamav folder in /opt/zimbra to zimbra:zimbra.
To update, follow the following:
Assuming that the new clamav version is in the directory: /home/snelson ( substitute your username for 'snelson' )
First go grab the latest ClamAV source from http://www.clamav.net/download (Current Stable Version is 0.90.2 )
tar -xvf clamav-0.90.2.tar.gz
Extract it to where ever you please. All this can either be done as root or as the zimbra user.  
cd clamav-0.90.2
If you do it all as root make sure you change ownership for the resulting clamav folder in /opt/zimbra to zimbra:zimbra.
 
Assuming that the new clamav version is in the directory: /home/snelson ( substitute your username for 'snelson' )
 
'''tar -xvf clamav-0.90.2.tar.gz'''
 
'''cd clamav-0.90.2'''
 
Next run configure inside of the clamav extract as following:
Next run configure inside of the clamav extract as following:
./configure --prefix=/opt/zimbra/clamav-0.90.2 --with-user=zimbra --with-group=zimbra
This assumes 'zimbra' is user and group id 'zimbra', change it accordingly to your system to match your zimbra user.
Note: I had to install gmp-devel and bzip2-devel so the configure could find all its header files. Your mileage may very. If you get an error about GNU MP missing install gmp-devel. "yum install gmp-devel", and "yum install bzip2-devel" in Fedora and Red Hat.


'''./configure --prefix=/opt/zimbra/clamav-0.90.2 --with-user=zimbra --with-group=zimbra'''
If your 'configure' goes well, and make sure it does as you don't really want ClamAV installed without some of its available testing ability being compiled.
 
Run: make

Run zmcontrol status to make sure antivirus is running. If it is, you're good to go.
You should check /opt/zimbra/log/clamd.log for errors, as well as freshclam in the same directory. Also /var/log/zimbra.log. To test out ClamAV I would suggest http://www.webmail.us/testvirus to send different variations of the EICAR test virus to one of your email addresses. Depending on if you have "Send notice ot recipient" check in Global Settings of the Admin Web UI, the user should receive around 20 email notifications of the emails being quarantined. Don't worry about the two that got through. Apparently ClamAV doesn't check for the techniques. There are although no virii included in those two emails, so it doesn't worry me. You can delete the previous install of clamav once you make sure everything is working. Delete the /opt/zimbra/clamav-0.90.1 directory and everythnig it contains. Again may want to wait a weelk or two to make sure you have the other version working well first.

Revision as of 13:40, 10 June 2008

Thanks to "Unilogic" AKA: Ben for most of this writeup. Parts have been updated to reflect lastest revision. If you have no idea how to upgrade or are a little shakey in doing the upgrade yourself, I recommend that you wait for the Zimbra official release. Note: This was done on Fedora Core 4 minimal install. Also, all the following can be done either as root or as the zimbra user. If you do it all as 'root', make sure you change ownership for the resulting clamav-0.90.2 folder in /opt/zimbra to zimbra:zimbra. This HOWTO also assumes that you are upgrading from 0.90.1 to 0.90.2 Please substitute the versions above for what you are upgrading from and to.

When ClamAV releases a new version and gets out of date, it will complain in its log files as such. clamd.log shows the following warning: LibClamAV Warning: ******************************************************** LibClamAV Warning: *** This version of the ClamAV engine is outdated. *** LibClamAV Warning: *** DON'T PANIC!

If upgrading from anything below 0.90.x, please refer to: *Updating CLAMAV from version lower than 0.90.0 To update, follow the following: First go grab the latest ClamAV source from http://www.clamav.net/download Extract it to where ever you please.

If your 'configure' goes well, and make sure it does as you don't really want ClamAV installed without some of its available testing ability being compiled. Run: make Assuming there are no errors, Run: make check and then make install. Again assuming no errors, you now have the new version installed into /opt/zimbra/clamav-0.90.2 Now we compare then copy your old clamd.conf and freshclam.conf from the previous version to the new version directory: cd /opt/zimbra/clamav-0.90.1/etc/ diff clamd.conf ../../clamav-0.90.2/etc/clamd.conf diff freshclam.conf ../../clamav-0.90.2/etc/freshclam.conf Above is just incase you are curious of what we are changing/over writing from the clamav defaults. cd /opt/zimbra/clamav-0.90.2/etc/ mv clamd.conf clamd.conf.org mv freshclam.conf freshclam.conf.org cd /opt/zimbra/conf cp clamd.conf /opt/zimbra/clamav-0.90.2/etc/ cp freshclam.conf /opt/zimbra/clamav-0.90.2/etc/


Run: zmcontrol stop to stop Zimbra. Now need to delete the symbolic link and re-link it to the new install:

cd /opt/zimbra ls -la 'grep' clamav ( should see 'clamav - /opt/zimbra/clamav-0.90.1' ) if so: rm -rf clamav ln -s /opt/zimbra/clamav-0.90.2 /opt/zimbra/clamav Create directory /opt/zimbra/clamav/db mkdir /opt/zimbra/clamav/db Now you should make sure zimbra owns all of clamav. chown -R zimbra:zimbra /opt/zimbra/clamav-0.90.2

Next we need to update the virus database. su zimbra Run: /opt/zimbra/clamav/bin/freshclam

Need to start Zimbra. Run zmcontrol start Run zmcontrol status to make sure antivirus is running. If it is, you're good to go.

  8. never been tested, and there absolutely no error checking.
