SSL connect error in wsman

Today I had to reset a Dell R520 which I dedicated to a new web service. The server was previously allocated to a different customer, so I wanted to wipe previous data, configurations and logs from it.

IPSec VPN between Linux and Windows 2012

I had to connect a Windows 2012 machine machine behind NAT to a CentOS 7 ipsec gateway with libreswan. No l2tp, just plain IPSec.
The windows machine itself was not a gateway, it was connected “alone”. So in my case there was no need for using RRAS.

In this second post, we’ll see how to collect event statistics from Postfix (deliveries, rejection, and similar) and publish them in snmp to our monitoring tools, specifically but not limited to Cacti.

There’s no magic here: Postfix logs details about it’s activity to syslog, and there is there we are going to search our events.

Postfix monitoring with Cacti, my way – part 1

In the next few posts I’ll show how I collect data from Postfix, publish them into net-snmp, and graph them with Cacti.

Postfix: mail loops back to myself

A quite common problem in postfix is when you find lines like this in your logs:
status=bounced (mail for domain.com loops back to myself)
Most of the time the problem is self-explanatory: domain.com’ MX record says mail should be delivered to the box itself, but postfix is not configured to be the destination

Yum error connecting IPv6 address

A simple yum update command fails. The scary thing is the error message which tells it’s impossible to connect to an IPv6 address:

New Horde packages

Horde-4, Imp-5 and the other usual components are available for CentOS6.
The packages were originally derived from OpenSuSE some time ago, using some scripts to convert them to my preferred environment. After that conversion, they are updated independently and do not depend from OpenSuSE anymore.
