Enabling firewall in FreeBSD – ipf

logo-full

This writeup will be short, to summarize how to enable ipf firewall in FreeBSD. In my experience with FreeBSD 5.4, it just work very well.

First, we need to enable it in the kernel configuration file. The default filename is GENERIC and located in /usr/src/sys/i386/conf/. First I make a copy of the configuration file, to BUDIHOST simply by using this command.

my.budihost.com# cp GENERIC BUDIHOST

Edit BUDIHOST, add these few lines:

options IPFILTER # IPFilter support
options IPFILTER_LOG # IPFilter logging support
options IPFILTER_DEFAULT_BLOCK # Block all packets by default
options RANDOM_IP_ID # RANDOM_IP_ID causes the ID field in IP packets to be randomized

These few lines also need to be added into /etc/rc.conf

ipfilter_enable=”YES” #Stateful firewall
ipfilter_program=”/sbin/ipf” # where the ipfilter program lives
ipfilter_rules=”/etc/ipf.rules” # loads rules definition text file
ipfilter_flags=”-F a -f /etc/ipf.rules” #IPFilter is enabled in the kernel and not module

After modification in your kernel configuration file, you need to rebuild and reinstall the new kernel with the new configuration.

my.budihost.com# cd /usr/src/
my.budihost.com# make buildkernel KERNCONF=BUDIHOST
my.budihost.com# make installkernel KERNCONF=BUDIHOST

Please check the error or any messages prompted after the buildkernel. If there is any problem, you might need to edit your configuration file, then rebuild. After you have sucessfully rebuild the kernel, then you can install it.

The firewall rules were stored in /etc/ipf.rules. You need to modify the file, to suite your production needs.

This is a sample configuration file. /etc/ipf.rules . You can open any additional port yourself, the configuration is simple straight forward.

Reboot your machine..

my.budihost.com# shutdown -r now

🙂

I have experience once, when I cannot ping to my own box. I also cannot check my email using webmail, the error message come out, no route to host. Its actually because of the firewall rule, u need to allow loopback interface to transfer. Solved! 😉

Google hacks

Google hacks..
Now I would like to share something I have to gain more 🙂 hhee..

Since Google have come into the internet, it seems have change the whole internet. Its really wonderful actually, from the comprehensive search engine, Google AdSense, Google Earth, Google Talk, and more to come I hope.

Now I will concentrate on Google Search hacks. I will show how you can search for a particular file on the internet, and search your own website, even you dont have a search engine. Really cool for a fully static HTML website right? 😉

At first, try to go to this link:
http://www.google.com.my/search?hl=en&q=mysql+ext%3Apdf&btnG=Search&meta=
You can see the search string in link provided. You can see, it can search for a particular topic and with what extension. You can also for a specific file using inurl. Try to search inurl:passwd.txt, you can see many search hits that found filename passwd.txt
This actually a vulnerablity to the owner of the system, where Google will reveal your confidential file. But, there is a solutions for system owner, using GHH – The “Google Hack” Honeypot. It will simulate the unsecure page, as if it is the vulnerable page, avoiding attackers from the actual possible vulnerable file.

Another tricks with Google is to search a particular file in your own site or domain. The example if in the link below:
http://www.google.com.my/search?hl=en&q=farhan+site%3Asbudi.net&btnG=Search&meta=
The search string used to search a keyword farhan in site sbudi.net.

I hope this article will be a guideline on how to find valuable information in the internet. Believe me, you’ll thank Google alot 🙂
