1. Download boot.img.gz
2. Insert your usb drive, be careful with the following command (I have my usb drive as /dev/sdb).
   zcat boot.img.gz >/dev/sdb
3. Now mount /dev/sdb
   mount /dev/sdb /mnt
4. Download Copy Debian netinst iso in /mnt. (Depending on your machine arch)
5. Now boot from USB. Plug-in the network cable or configure your wifi and perform the installation.

In case you already having a LVM from earlier distribution you may get error of partition already in use while configuring your LVM. In this case get to the console by pressing alt+ctrl+F2 key (F2 or F3) and hit enter. Now give vgchange -aln then get back to your partitioning section and proceed.

A good tutorial is available on the debian site.

To configure wireless network on Back Track 4 (PwnSauce)

1. Identify your wireless extensions, for example you found wlan0
2. Create a wpa_supplicant.conf file with the following entries:
3. network={
   ssid=”NetworkName”
   scan_ssid=1
   key_mgmt=WPA-PSK
   psk=”Password”
   }
4. Then issue command:
   wpa_supplicant -i wlan0  -c wpa_supplicant.conf
5. on another terminal give:
   ifup wlan0

In case of issue, check the logs

Download  & install xchm from:

If your kshell scripts which you migrated from RHEL4 or earlier are behaving strange, for example a small script:

[root@localhost ~]# cat /tmp/test.ksh
#!/bin/ksh
#demonstration
echo “\n”

it’s going to give a new line, right? But no, with the default kshell installed it’s not the same, as redhat 5+ is not using pdksh(public domain korn shell). When we execute the above small piece of kshell code:

[root@localhost ~]# ksh /tmp/test.ksh
\n
[root@localhost ~]#

Which is not a new line output (as expected).

To make it working, do yum install pdksh ( in case your server is registered with the redhat) else you can download pdksh rpm from centos site and do rpm -ivh pdksh-*.rpm

Now next step would be, either remove ksh rpm or better use alternatives command (you need to be root to use it) . Second one option is more useful, so here we go:

[root@localhost ~]# alternatives –config ksh

There are 2 programs which provide ‘ksh’.

Selection    Command
———————————————–
*+ 1           /bin/ksh93
2           /bin/pdksh

Enter to keep the current selection[+], or type selection number:2

Select option 2 (showing path to pdksh)

Now test your ksh script.

[root@localhost ~]# ksh /tmp/test.ksh

[root@localhost ~]#

It worked, echo “\n” is working as expected !!

That’s it…
