[SOLVED] MDM Plugin Webapp - Ubuntu 18.04

[eli]

On the same machine, you can set the PLUGIN_MDM_SERVER_SSL to false. This avoids all certificate issues.
I recommend to use the server name from the webserver configuration (vhost) instead of the localhost address.

Why are you using a self-signed certificate? LetsEncrypt is activated in a few minutes and accepted on the most devices out-of-the-box.

Hi AnotherAndy and eli,

I have in the Apache Config: ServerName https://kopanotest.topleveldomain.ch
This Servername without https:// i have writen into the MDM config. I have also tested it with https://
I also set PLUGIN_MDM_SERVER_SSL to fals but it doesn’t help.

Where do I see if apache is listening on 127.0.0.1 ? I didn’t find in the apache2.conf .

Yes I will try with LetsEncrypt today evening or tomorrow to install it and get it working.

[thctlo]

what do you see if you run : apache2ctl -S

[hispeed]

I see this:

root@svgwma-kopa-02:/# apache2ctl -S

kopanotest.XXXXX.XX <- this I wrote in the mdm config!

[AnotherAndy]

means your apache is listening on every interface available.
But with the config
.
<?php
define(‘PLUGIN_MDM_USER_DEFAULT_ENABLE_MDM’, false);
define(‘PLUGIN_MDM_SERVER’, kopanotest.topleveldomain.ch’);
define(‘PLUGIN_MDM_SERVER_SSL’, true);
?>
it should work…if not check the z-push logs if you can find anything or the kopano logs

[hispeed]

No luck at the moment. Updated Webapp restartet everything. configured like you said but still the same error.

Log Level - Debug
root@svgwma-kopa-02:/var/log/z-push# nano z-push-error.lorg <- No entries
root@svgwma-kopa-02:/var/log/z-push# nano z-push.log - No entries

Also no Kopano log entries…

I found something in the webapp and look at the version. I can’t see the Z-Push Version! maybe there I have something wrong?

Z-Push: Version nicht verfügbar / Z-Push Version not available

[AnotherAndy]

ok…no more ideas.
maybe you can check:

[thctlo]

ok, so you did not configure your apache.
You “should” see something like this.

A sample what creates this, can be found here.
https://raw.githubusercontent.com/thctlo/debian-scripts/master/setup-apache2-vhost-defaults.sh

This catches every IP and hostname and makes sure NONE of you vhost can get abused.
all my IP hosts have

a sample of the IP cert.

  #   A self-signed certificate, use the IP adres for CN (Common Name)
    # mkdir -p /etc/ssl/local/{certs,private}
    # openssl req -new -x509 -days 365 -nodes -out /etc/ssl/local/certs/ip-wan.cert.pem -keyout /etc/ssl/local/private/ip-wan.key.pem
    # chown root:www-data /etc/ssl/local/certs/ip-wan.cert.pem
    # chown root:www-data /etc/ssl/local/private/ip-wan.key.pem
    # chmod 644 /etc/ssl/local/certs/ip-wan.cert.pem
    # chmod 640 /etc/ssl/local/private/ip-wan.key.pem

and optional add one of these or create an index that people should use a hostname and not an ipadres.
Bots/script kiddies use ipadress. point your fail2ban to these logs and bye bye script kiddie.

    # We dont allow anyone on the external ip, normal persons types a name and not ip.
    <Location />
      Require all denied
    </Location>

    #or choose to redirect the request to your webserver.
    #Redirect permanent / https://www.example.com/

[thctlo]

@eli have a look here.
https://forum.kopano.io/topic/1453/kopano-and-outlook-integration/6
That might help also in setting up correctly.
Combine that one with this post and you have all the correct info.

@thctlo I have tried to do your steps for the certificates and apache vhost.
unfortunately at the moment the webapp is not available anymore.

When I go to: https://192.168.0.80/webapp i will be redirected to: https://www./webapp

Can you help me with fixing that?

[AnotherAndy]

hi @hispeed
ist you server running on a LAN or with a public IP?
https://forum.kopano.io/topic/1042/mdm-plugin-not-working/17
this guy had a smiliar problem -his problem was the apache config.

[hispeed]

Hi,

It’s just a testserver behind my pfsense at home. I recieve and send (sending -> it doesn’t work yet) mails via SMARTHOSTS. The server doesn’t have a public IP. My pfsense is forwarding everything.
So SSL is secondary but nice to have because the server is reachable from outside for webapp and z-push.

EDIT:

Maybe I should use this VHOST config on this post?

https://forum.kopano.io/topic/1042/mdm-plugin-not-working/14

[AnotherAndy]

hi,
now I understand. So what happens, if your do a
curl https://externalURL/Microsoft-Server-ActiveSync on the bash of the Server?
you should get
<html>
<header>
<title>Z-Push ActiveSync</title>
</header>
<body>
<font face=“verdana”>
<h2>Z-Push - Open Source ActiveSync</h2>
<b>Version 2.4.2+0-0</b><br>

• you also can try http://localhost/Microsoft-Server-ActiveSync - it should get the same

[hispeed]

Yes this works but without SSL. so just curl http://
I also have my Iphone connected which is working fine, so Z-Push is probably fine.

[AnotherAndy]

wow…running out of ideas…can you check the apache access logs, if the kopano webapp MDM tries to access the z-push url?

[thctlo]

This is pretty simple guys, make sure you resolving is correct thats it.
Then test with names and not ipadresses.
That is key if you use SSL, if you want to use ip adressen, then setup without ssl.

What i posted is correct and is in production over 2 years, but i made sure the resolving is correct.
You have the solutions, now fix you dns/resolving to make it work.

[thctlo]

This :

/etc/hosts
127.0.0.1       kopanotest.mydomain.ch      localhost
::1             localhost6.localdomain6 localhost6

is wrong, now your “localhost” resolves to kopanotest.mydomain.ch
yes, this is possbile, but correct would be localhost.mydomain.ch
Not that i advice that.

/etc/hosts
127.0.0.1       localhost localhost.localdomain
::1             localhost localhost6.localdomain6 localhost6
192.168.1.1 kopanotest.mydomain.ch       kopanotest

That should be a correct hosts file. (correct the ip of kopanotest)

[hispeed]

Hi @thctlo

After spending hours of trying and fixing the virtual host file of apache I can now connect again to Kopano.

EDIT 2:
Unfortunately right now I can’t access via LAN because I only allow domain names. I have a pfsense what do I need to do, or do I have to reconfigure virtual host file from apache2?
–> This is fixed via Pfsense and DNS Resolver!

Yes I have succesfully installed certbot and I got a certificate which I also set up like you explained.

Here is my virtualHost config:

# Non SSL

I will test later if MDM is working and If I can send mails now or not.

EDIT:
MDM is not working yet. Can I remove it and install it again?

[hispeed]

If you have this problem you have to reconfigure correctly your apache vhost configuration and also get a proper certificate.

Then you have to adjust the config from mdm to:

<?php
define(‘PLUGIN_MDM_USER_DEFAULT_ENABLE_MDM’, true);
define(‘PLUGIN_MDM_SERVER’, subdomain.topleveldomain.ch’);
define(‘PLUGIN_MDM_SERVER_SSL’, true);
?>

This is what I need to do after I have reconfigured my apache vhost config. The problem is solved.

[thctlo]

Hi, good to hear this is fixed.
A correct resolving is so important.

And sorry for the late reply, there was a lot going on the last 3 months.
