Check out the madwifi driver as follows:

sudo ifconfig ath0 down
sudo ifconfig wifi0 down
svn -r 3876 checkout http://svn.madwifi.org/madwifi/trunk/ madwifi-ng
cd madwifi-ng
patch -Np1 -i ../madwifing-r3876.patch
sudo ./scripts/madwifi-unload
make
sudo make install
sudo depmod -ae
sudo modprobe ath_pci

I was playing with PaiMei and trying to get some initial stuff working on Pai Mei Reverse Engineering framework by Pedram Amini.
It was a smooth ride until the following steps:
1. Install MySQL
2. Install wxPython
3. Install GDE and uDraw

There was a slight problem in the __install_requirements.py file that it would always look at C:\Program Files for the files whereas my files were in S:\Program Files.
Either way a small change from C to S in the __install_requirements.py did the trick. Thereafter, when I ran __setup_mysql.py script I got the following error:

Seems like MySQL should not be running in “strict” mode while you run this script. I got this information from the following link:

I’ve been struggling to find the best working version of John so that it can crack MS Cache outputs from Cachedump (of course, this functionality is now included in fgdump). Running fgdump gives two files host.pwdump and hostname.cachedump. I’ve found 127.0.0.1.pwdump and 127.0.0.1.cachedump files upon using fgdump without any parameters.
So now you have the Cached credentials but then comes the big problem of cracking those. So there’s the jumbo patch for john-1.7.2.
Following commands need to be executed to get this patch going:

$ tar zxvf john-1.7.2.tar.gz
$ cd john-1.7.2/
$ wget http://www.openwall.com/john/contrib/john-1.7.2-all-9.diff.gz
$ gzip -d john-1.7.2-all-9.diff.gz
$ patch -p1 <john-1.7.2-all-9.diff
$ cd src/
$ make linux-x86-sse2

You get some warnings upon compilations but the executable works very well.

Go ahead and get cracking:
$ cd run/
$ ./john –format=mscash

Last night I was trying to get a VeriSign issued SSL certificate installed on my ASA using Cisco ASDM 6.2. I installed the Intermediate CA and the CA certificates all installed. I then imported the SSL certificate into the “Configuration -> Device Management -> Manage Certificates -> Identity Certificates” but it did not seem to work. I kept getting an error “Failed to parse or verify imported certificate”. The certificate was in the .p7b form. Changing the format of the certificate to X.509 Base64 Encoded format resulted in acceptance of the certificate.
I sincerely hope that Cisco alters its error messages to accurately reflect that .p7b is not a format supported by them.

Update: This link has the information on how to install SSL certificates on ASA:

I wrote a very small script to set static IPs on a kubuntu box.

#!/bin/bash
if [ $# -lt 4 ]
then
    echo "Usage: $0 <interface> <ip> <netmask> <gateway> <dns1>"
exit
fi
ifconfig $1 $2 netmask $3
echo "Static IP set"
route add default gw $4
echo "Routes added"
if [ "$5" != "" ]
then
    echo "nameserver $5" >>/etc/resolv.conf
fi
echo "DNS set"

The problem: Using Digital Certificates issued by a Certification Authority (CA) with curl.

The situation: I have a .cer (Digital Certificate) file, .pfx (Personal Information Exchange file i.e., the private key for the certificate). I cannot use either of these to authenticate to the web service as curl would not accept these formats.

The solution:
1) Convert it into PEM format (X.509 certificate) using openssl.
openssl pkcs12 -in abcd.pfx -out abcd.pem
Enter a passphrase and a password.
2) Still you cannot use this with curl because you’d get a few errors.
3) Convert this PEM certificate into three different certificates for the client, the private key and the certification authority certificate.
openssl pkcs12 -in abcd.pfx -out ca.pem -cacerts -nokeys
openssl pkcs12 -in abcd.pfx -out client.pem -clcerts -nokeys
openssl pkcs12 -in abcd.pfx -out key.pem -nocerts
4) Use the following command:
curl -k https://www.thesitetoauthenticate.com/test -v –key key.pem –cacert ca.pem –cert client.pem:

This stuff is also mentioned on curl forum at http://curl.haxx.se/mail/archive-2005-09/0138.html

Cisco ASDM is quirky in the sense that if the right Java version is not found it will just puke with errors that make no sense. This is what my java log looks like:

It happens because the ASDM launcher is not capable of running on newer JVMs. Since I had older JVMs, I went into Control Panel -> Java. Click on the Java tab, followed by clicking the “view” button. This will show you the current JVM being used. If you have older JVMs click on Find (you will have to select the folder where you suspect older JVMs to be…which in my case was c:\Program Files). If you don’t find an older JVM then just install an older version and it will work.
