Beta Information

2021-06-18 (6.10-10)

Added the same improved error handling to drop-offs with multiple recipients. Corrected problem in Inbox and global list of all drop-offs where requests (in yellow) would be sorted by their start date, not their creation date.

Greatly improved error handling of requests with multiple recipients, where some recipients may fail and others succeed. Also now handles email addresses with < and > around them, and should skip any other words that aren't email addresses.

Fixed problem where upgrading from a very old RPM could cause it to miss the DB schema upgrade.

Requests now start yesterday (exactly 24 hours before server's local time) to avoid timezone issues.

There is now a new tool /opt/zendto/sbin/check_templates which will check your *.tpl files against the MD5 checksums of what is expected for this version. For any that don't match, it will ask you if it should use the default correct version and overwrite your old/outdated/modified one. It is run as part of the /opt/zendto/bin/upgrade process, and hopefully will fix some of the problems caused by outdated template files.

AD Authenticator now supports reading paged results from the AD server. If your AD settings are set to deliver few results at a time, this should make things work better.

The latest betas I believe to be stable are:

However, I strongly advise you to use the beta installer on a fresh system.

The file at will tell you the latest beta version number.

About the Installer

Instead of the old VM images, I have written an installer which will automate (almost!) the entire process of installing ZendTo on to a minimal server installation.

It talks to you along the way, asks if you want to do each of the 8 steps, and asks you to confirm the odd question or two. It pauses quite a bit so you can see what it's doing, giving you the chance to stop it temporarily (Ctrl-S) to read what it's done before you continue (Ctrl-Q).

It is also modular, so you can run each of the 8 parts alone; you may want to do this when, for example, there is an update to PHP5 and you want to just rebuild PHP with "big uploads" support.

The parts are:

  1. Install web server and development tools.
  2. Install the most recent PHP it can find.
  3. Install and configure virus scanner, including SELinux support for it.
  4. Configure firewall holes for ssh, http and https.
  5. Configure web server and PHP.
  6. Install ZendTo itself and configure email sending & usage stats graphing.
  7. Configure SELinux on CentOS and RedHat 6, 7 & 8.

I have tested the installer on:

  • CentOS 6, 7, 8
  • RedHat Enterprise Linux 6, 7, 8
  • Ubuntu Server 14, 16, 18, 19, 20
  • Debian 8, 9, 10
  • SUSE Enterprise Linux Server 16
  • openSUSE Leap 15
  • FreeBSD 11, 12

There are 2 things the installer does not currently do:

  • Generate a production-ready SSL certificate for the website. It does create the SSL website, but only with a self-signed certificate. You might want to look at as a very good (fully automatic) way of getting free SSL certificates.
  • Configure MySQL, as new installations will not need it anyway.

How To Get It

You can download the new installer now. Then just unpack it and run it as root with

tar xzf install-beta.ZendTo.tgz
cd install.ZendTo

If you look inside its Ubuntu-Debian or CentOS-RedHat directories, you will see the 8 stages. The main will ask you whether you want to run each stage and will walk you through what it is doing. Feel free to pause (Ctrl-S) or stop it (Ctrl-C) at any time; if you stop it you can just re-run it. Each of the 8 stages can be run independently at any time by just running that particular stage number's script.

There is 1 command-line option that can be used on either or any its stages: "--defaults" tells the installer to just use the default values it suggests, and not to pause long at any point. It will run entirely unattended.

After you have installed the package (or just updated to the new rpm/deb/tgz package), you will find the new upgrader for preferences.php and zendto.conf in /opt/zendto/bin/upgrade. Just run it. It will automatically copy all your old preferences.php and zendto.conf settings into the new files, while keeping your comments, extra "define"s you may have added, and such like. It keeps copies of all your previous ones in an "old" sub-directory.

Tell Me What You Think

Please do tell me what you think of this upgrade, and in particular the new installer. Please report all bugs, issues, suggestions and so on.

The mailing list would be the best place, so we can all discuss them, but otherwise you can of course email me too.
