For Christmas, I got a new hard drive for my laptop. As all accessories for laptops, it is rather expensive. But still less expensive and extravagant than buying a new computer when you don’t really need a big CPU power. My goal was not having a huge capacity, but rather speed and reliability.
Here is the update of my previous test of SinFP.
I compared then the output of SinFP and Nmap on different machines, and found out that SinFP made a slightly better job than Nmap in OS detection, though it is not the primary goal of Nmap whereas it is the one of SinFP.
However, I made a mistake that the author of SinFP made me aware of.
I conducted the tests of Nmap using the package of my distribution, thinking it was the latest one.
Actually, it was only the version 4.10. Moreover, the current version, 4.20, brought up a new OS detection engine.
Therefore, a new test with version 4.20 was absolutely needed.
Last week, I found out a very interesting program, SinFP (those who are french and read the Misc magazine must already know 
).
Its goal is to help you detecting what operating system a remote machine is running.
Well, you will tell me that we already have many programs that does this job, starting from the so famous nmap… but the approach is quite different this time.
I got a weired issue with Linux clients while it worked fine with Windows machines. For some reason, the /etc/resolv.conf did not get updated.
I found out a workaround thanks to this page.
Of course, your server configuration file must contain (if 192.168.1.1 is your DNS server):
push "dhcp-option DNS 192.168.1.1"
You want to apt-get update / upgrade your system but you don’t want the package xxx to be updated ?
WMWare does not really work out of the box on Ubuntu.
There is an issue concerning the ACPI, which makes the guest machine so slow that it is barely usable.
I took several pieces of bash configuration from the net and use them as follow to be more productive with my terminal. A must have setting !
I had several bad experiences losing my data in my life. Sometimes because of the hardware, sometimes because of my stupidness or inexperience. At least, it learned to be careful. I backup my data regularly, and on several support concerning the important ones.
