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.

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

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

Fixed: Cisco VPN Client, a Huawei 3G usb key and network sniffing

I ran into a problem widely documented on the Internet. Using a USB 3G Huawei Internet key (in particular for me it is an E1692), for some reason the vpn created with Cisco VPN Client does not work. Indeed, the vpn is regularly established, but no packet is effectively routed through the vpn itself. Googling
