I often review various vulnerability scanners.  When I review them, I look at several different things:

  • were they able to find a vulnerability I previously missed?
  • are they accurate in their findings?
  • how quickly do they complete an audit compared to “insert some other vulnerability scanner here”?
  • sometimes I will also grab the tcpdumps of the audits for even further analysis
  • how accessible and easy are they to use by “skiddies”?
  • based on the tcpdumps + noise generated on the server logs, are the audit signatures of wapiti easy to detect?

My desktop computer is a couple of years old.  It serves me well for what I do.  I just got a new laptop.  In terms of hardware, the laptop is much different.  The desktop is a quad-core AMD 900 series with an ATI 4500 series gpu running backtrack 5r3.  It has 8GB of memory and standard SATA drives.  The laptop is an Intel i7 cpu, with SSD drive, NVIDIA 660M gpu, and 8GB memory running backbox 3.  The internal SATA drive is slow as fuck (just putting that out there).  I have the OS on the SSD drive and my home folder on the SATA drive.

Here are the specs as seen by pyrit list_cores from each along with the benchmark tests:

One thing I can’t stand is waiting on software to download.  I mean, I have a blazingly fast internet connection and I expect everything I do to be blazingly fast also.  So, one thing I noticed was my backbox linux installation was taking forever to download updates.  Looking into why, I noticed there were static addresses used in the /etc/apt/sources.list for ubuntu software repositories.

So here is how to fix it so that you always get the mirror closest to you:

So I wrote this script because I often need to run tcpdump on a remote host and then view it in wireshark.  The old method was to run tcpdump on remote host, scp/rsync the file back to my local machine, open it in wireshark, view it.  This script saves a lot of time.  It assumes you are logging in as root and will need modified if you are running as a normal user (change root to your username and make sure you have sudo privileges for tcpdump)

# By Ed Wiget
# This runs tcpdump on a remote hosts and pipes it back locally to wireshark to view in realtime
# 20130205 - original script
if [ $1 == "" ]; then
	echo "What is the remote host by fqdn, i.e."
	read RHOST
wireshark -k -i <( ssh -l root ${RHOST} /usr/sbin/tcpdump -i eth0 -w - )
# after you kill wireshark, the tcpdump still runs on remove host...we need to kill it
PIDOF=`ssh root@${RHOST} "ps aux | grep [t]cpdump" | awk -F" " '{print$2}'`
echo "killing pid ${PIDOF} on ${RHOST}...please wait...."
ssh root@${RHOST} "pkill tcpdump"
# now we make sure it is killed
PIDOF2=`ssh root@${RHOST} "ps aux | grep [t]cpdump" | awk -F" " '{print$2}'`
if [ ${PIDOF2} == "" ]; then
	echo "pid check returns ${PIDOF2}"
	echo "pid check returns ${PIDOF2}"
