Frank 8: SaMBa rpm packages with AD DC support

I had to upgrade some old CentOS 6 servers with even older SaMBa NT4 DC on it. I went to CentOS 8.
Since AD DC functionality is not included in the C8 rpms, I recompiled the SaMBa rpm packages from Rawhide. All went smooth. I did the upgrade and after some trial/error/google cases (it

Atahualpa lives!

The blog you are reading is (was, until yesterday) based on the popular Wordpress CMS. The theme is Atahualpa. Given my inexpertise in the field, I don’t even know why I chose it about ten years ago. But over time I realized that for me it is a gem.

RP-PPPoE on CentOS 8

As part of the new implementation of Casa, I needed RP-PPPoE for CentOS 8. As it is no longer, or still, available in Epel, I recompiled the RPM. You can find it in my Lux repo, along with my version of PPP with the network-scripts-ppp package re-enabled. Nice for people like me who

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.

The only non-trivial part was to erase the Lifecycle Controller logs which in theory are meant to be

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.

Postfix monitoring with Cacti, my way – part 2

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.

I am interested in data about Postfix queues sizes possibly on multi-instance configurations, and about Postfix events.
I decided to use SNMP instead of launching scripts directly by Cacti for a number
