See also **[[internet:mail:zimbra:zimbra_zextras_auth|Zimbra with Zextras Auth]]**

**Documentation**: https://docs.zextras.com/suite/html/index.html

===== Zextras Licensing =====

**License File Management**: https://docs.zextras.com/zextras-suite-documentation/latest/license-file-management.html

**License Download**: https://store.zextras.com

Sometimes the permissions get messed up on the downloaded Zextras license file:

<file>
chown zimbra.zimbra ./license_*
chmod 777 ./license_*
mv ./license_* /opt/zimbra/
su - zimbra
zxsuite core doUploadLicense ./license_*.zx
zmprov fc zimlet && zmprov fc all
</file>

===== Upgrade =====

http://wiki.zextras.com/wiki/ZeXtras_Suite_Installation_Guide#ZeXtras_Suite_full_Upgrade

:!: Installing a newer version will automatically perform an **upgrade**.

===== Installation =====

<note warning>ZeXtras Suite needs to bind on TCP port 8735 in order to operate for inter-instance communication.  The ZeXtras Chat module needs to bind on TCP ports 5222 and/or 5223 in order for any XMPP feature to be functional.  Please verify no other service listens on these ports and that port 8735 is properly filtered from public access by your firewall.</note>

<file>
apt install binutils
</file>

<file>
rm -rf ~/zextrasinstall.old && mv ~/zextrasinstall ~/zextrasinstall.old
mkdir ~/zextrasinstall && cd ~/zextrasinstall
wget --limit-rate=300k http://download.zextras.com/zextras_suite-latest.tgz

tar -xzvf zextras_suite-latest.tgz
cd zextras_suite/
./install.sh all
</file>

===== Zimbra DoS Filter =====

<note important>Zimbra 8+ users might experience slowness and AJAX errors when accessing the Zimbra ZWC or Administration Console because of the Zimbra DoSFilter. In this case, raising the number of Maximum Requests per Second is suggested (see http://wiki.zextras.com/DosFilter for further information)</note>

Whitelist your IP or subnet:

<file>
zmprov gcf zimbraHttpThrottleSafeIPs

zmprov mcf +zimbraHttpThrottleSafeIPs 192.168.0.0/24
zmmailboxdctl restart
</file>

View results:

<file>
grep DoSFilter /opt/zimbra/log/mailbox.log
zgrep DoSFilter /opt/zimbra/log/mailbox.log.*

grep DoSFilter /opt/zimbra/log/zmmailboxd.out
zgrep DoSFilter /opt/zimbra/log/zmmailboxd.out.*
</file>

===== Backup =====

**[[http://wiki.zextras.com/wiki/ZxBackup_Admin_Guide|ZxBackup Admin Guide]]**

**[[https://docs.zextras.com/zextras-suite-documentation/latest/backup.html#_backup_on_a_third_party_store_beta|HowTo Use S3 as Backup Storage]]**

**[[https://wiki.zextras.com/wiki/Zx_Backup:_External_Backup|HowTo - Zextras Export/Backup to External Storage]]**

Create the mount point as ''zimbra'' user:

<file>
su - zimbra
mkdir /opt/zimbra/backup/zextras
</file>

Mount NFS backup storage:

<file>
vim /etc/fstab

# Add Zextras Backup store
ip.of.nfs.server:/backup/va-zimbra               /opt/zimbra/backup/zextras  nfs _netdev         0 0
</file>

:!: Make sure the permissions are correct:

<file>
chown zimbra.zimbra /opt/zimbra/backup
</file>

Finally, initialize the Zextras Backup:

**Zimbra Administration Console -> ZeXtras -> Backup -> Initialize NOW**

:!: To hide the ''Briefcase'' tab, uncheck it in the CoS.

==== Migrate All Briefcase Data to Drive for All Users ====

<file>
for user in `zmprov -l gaa | grep -v -e galsync -e spam -e ham -e virus | sort`; do zxsuite drive doImport $user; done
</file>

==== Migrate All Briefcase Data Deleting Source Files ====

The command ''zxsuite drive doImport'' has the attribute ''deleteSources true'' which **deletes source files from the briefcase**. You may do the import again with that parameter to clean the briefcases.

:!: Files already imported in Drive will not be modified if you don't use the ''overwrite true'' attribute.

</file>
