Cisco VPN Client on Windows 10 without SonicWALL VPN client

There’s plenty of info on the net about how to install and make work the old, unsupported Cisco VPN Client on Windwos 10, so I’ll avoid making cut/paste here.

The only advice I would like to add is that contrary to what I read around, it was perfectly feasible to me to use directly the

Windows 7 setup on Zotac BI323 hangs at “Completing Installation”

If you try to install Windows 7 on a Zotac BI323, you will find that you have to slipstream the xHCI drivers in the installation media before being able to access the hard drive and install the system. This is covered in an article by Zotac, and worked well for me. The utility provided

Arduino for heating system thermostat and garden irrigation timer

This is my Arduino project for home heating system thermostat and garden irrigation timer.
The project was developed just for fun: I had no previous knowledge of electronics; and the code is awful, being hacked from time to time with no particular design in mind. But it’s fun, most of the time it works

Arduino: how I use it

I’m using Arduino for some time now to automate the heating system and the garden irrigation system.

Having a Linux box installed near my Arduino in my “workroom/lost time office”, I find much more convenient to interface to the Arduino from the Linux computer itself, than connecting a PC and using the usual IDE.

Recover saved wifi passwords after changing wireless adapter

I changed the WiFi NIC in my notebook. After that I discovered that the new NIC did not have access to the saved WiFi secrets that where saved prior to chaning it.

I ran a well known utility from NirSoft, wirelesskeyview. Thank you again, Nir.
The utility confirmed what was easy to argue, that

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.
I found it difficult to find

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

Alcatel Lucent AP-103 connected clients do not get Internet access via Telecom Italia ADSL

Be aware: I did not go too deep into this problem. Any further observation is welcome.

A colleague had an ADSL internet access from Telecom Italia attached to a Cisco 857 router, which did work fine. He connected to an Alcatel Lucent AP-103 access point (manufactured by Aruba Networks) to the router. WiFi clients were
