I remember being so happy about 0trace when I started to write some Backtrack related articles because even though 0trace is fairly simple it is really useful to locate the full path to devices you are investigating. In the article below I will explain the necessary 0trace input from the command line, what needs to be done to complete a successful trace to a target using 0trace, and provide some example of devices in front of and behind a firewall blocking ICMP or traceroute requests.
OK this article is sort of silly and will be fairly short and to the point but earlier I was trying to find the process name of the OSX Lion firewall. During the process of looking for the OSX Lion firewall process name I learned a bunch of little firewall tidbits such as there are a ton of settings you can set from the command line, there are third party OSX Lion Firewall GUI configuration tools, and there are complete third party firewalls available for install on OSX Lion.
If you are not hip to pfSense I suggest you check it out. It is an open source firewall that is making waves in InfoSec. The pfSense guys have a great howto for configuring IPSec VPN on the pfSense firewall as well as making connections via a freeware Windows IPSec VPN client called Shrew Soft which can be read by clicking here. The only item lacking in the article is a recommendation for a Mac OSX client as well as configuration tips for a Mac OSX client which is the sole point of this article. Below is information about where to download a freeware Mac OSX IPSec VPN client and then the necessary configuration to make a connection to the suggested settings noted in the howto of the pfSense web site.
Not sure if Fortinet makes it impossible to find the FortiClient SSL VPN application for Mac OSX on purpose or not but it appears to be free for the simple client version so I wanted to provide a location to download the client easily. On Windows you can bring up Internet Explorer and make a SSL VPN connection easily but since IE is not available on OSX it is necessary to have the stand alone FortiClient SSL VPN application. Be careful if you are going to download the Fortinet FortiClient elsewhere as if it is anything other than the simple SSL VPN client it is really bloated.
I travel a lot and I have noticed that the timezone on my mac book wasn’t updating properly. I was getting lots of wrong meeting times in Outlook and various other apps that depend on time. I was getting pretty annoyed at this and decided to figure out what was up. I was pretty sure this was supposed to happen automatically so I decided to have a look and figure out what was going on.
