Zimbra multi server – servers and services show as down in admin interface.

Solution for servers and services shown as down in zimbra admin console:

 

But they are actually up and running.

In a m ultiserver setup servers and services show as down in admin interface.

FACTS:
Rsyslog is not modified by zimbra installer.
In order for servers and services to look fine (when they are fine) in the admin console the logger module (syslog) is used.
By default rsyslog does not listen on tcp/udp and the Zimbra installer does not provide any changes to its configuration in order to make it happen.

So you need to open /etc/rsyslog.conf and uncomment following lines:

-------------------------------
# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# Provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 514
-------------------------------

Then restart rsyslog.

Also remember that you should check on the servers around (except the one supposed to receive the logs) that the correct log server is set. For this you can run as user zimbra:

zmprov gacf |grep zimbraLogHostname

This should return the hostname of the log recipient.

In case that is not correct, you can set it with:

zmprov mcf zimbraLogHostname example.com

Also, as root, you should run:

/opt/zimbra/libexec/zmsyslogsetup

This should make sure that the logserver you just set within zimbra is also used to reconfigure the rsysolg running on the system.

postgresql FATAL: database system identifier differs between the primary and standby

This is due to two possible reasons:

  1. you did not do the initial filesystem sync (usually rsync)
  2. the recovery.conf contains errors

Docker cheat-sheet

Docker is great for development, but also, it gives you the superpower of extremely small images to easily move around docker containers.

I need this for personal stuff, but I think it can be useful to others, so let’s share it.

Asus X202E touchpad sensitivity with Ubuntu

The ones out there who decided to drop Windows 8 in favor of Ubuntu after buying an Asus X202E will probably face the issue of a too sensitive touchpad which makes the laptop barely usable, with a lot of random unwanted clicks especially during the “two finger scrolling”. The two finger scrolling is a feature I really don’t want to give up as well as the touch to click one, as i find them really convenient as long as I have to use the laptop as laptop, which means without an external pointing device such as a mouse.
