This post is just to point to the page where the great
Rene mantains the .deb packages for Forticlient SSLVPN Linux client (instead of .tar.gz provided by Fortinet).
You can find the .deb files built by Rene in
his blog Bits and Bites.
Kudos to him!

HA Cluster with DRBD file sync which adds file sync configuration between cluster nodes]
: tested the configuration also with UPDATED on March 7, 2017 Ubuntu 16.04 LTS]
This post show how to configure a basic High Availability cluster in Ubuntu using
Corosync (cluster manager) and Pacemaker (cluster resources manager) software available in Ubuntu repositories (tested on Ubuntu 14.04 and 16.04 LTS). More information regarding Linux HA can be found here.
The goal of this post is to setup a freeradius service in HA. To do this we use two
Ubuntu 14.04 or 16.04 LTS Server nodes, announcing a single virtual IP from the active cluster node. Notice that in this scenario each freeradius cluster istance is a standalone istance; I don’t cover application replication/synchronization between the nodes (rsync or shared disk via DRBD). Maybe I can do a new post in the future 🙂 [ ] I did the post Continue reading “Configure basic Linux High Availability Cluster in Ubuntu with Corosync”

OTRS Help Desk is an
open source application (with Enterprise support) that has a lot of useful features: ITSM, Surveys, Time Accounting and System monitoring.
I use it on my company as a Service Desk for
Security purposes (and more).
As you can read from our Success Story one of the feature we currently appreciate is the ability to track all the email exchanges into tickets simply putting ticket number in email Subject end CCing the proper configured email address. This allow us to interact with external parties without the need for other people to access our OTRS istance. Continue reading “Configure OTRS to process multiple Tickets in email Subject”

Security Onion is an Ubuntu based distribution created to handle a lot of Security task.
One of the security tool installed is
SNORT, the best open source Intrusion Detection System (IDS). Security Onion use Pulledpork to get IDS rules and process them.

Metasploit is my favorite tool while I do Pen Test and Secuirty Checks. I use also Nessus for Vulnerability Assessment and integrate Nessus and Metasploit is a must.
Follow a short guide on how to launch Nessus from Metasploit (for reference, I used NESSUS 6.5 and Metasploit PRO but also Community Edition should be ok).

One of the problems I encountered in my job is to get syslog (udp/514) logs from a server that support only one syslog destination and resend these logs to two or more servers (log archiving, security appliance etc).
To do this I used
rsyslog and Ubuntu Server (14.04 LTS) acting like a syslog relay.
In this scenario the remote appliance sends the log to the Ubuntu Server (listening on port udp/514) and the server store&forward the logs to one or more server/device. Continue reading “Rsyslog – Store and Forward messages to other hosts”
