Basic Backtrack For Newbie Dummies
Basic Backtrack For Newbie Dummies
Once the installation of BackTrack is done, the default username and password required to log in are root / toor.NOTE: You will not be able to see the password as you type it.After you are logged in you can start the GUI Environment by issuing the startx command.In rare occasions (such as after a VMware tools install, or when using unsupported Video cards), X will refuse to start. If that happens you have several options you can try in order to fix the issue:Reconfiguring the X server package, you can reset (and often fix) Xorg configurations with the following command: root@bt:~# dpkg-reconfigure xserver-xorgIf you are using Backtrack 5 on x64 with KDE you should try the following: root@bt:~# rm /root/.kde/cache-*NOTE: Sometimes you may need to also remove the cache folders in /var/tmp by issuing the following command: root@bt:~# rm -rf /var/tmp/kdecache-*If you haven’t noticed yet BackTrack does not boot with networking by default in order to increase its stealth.We will first set up the networking manually. In the following example we will assume the following addresses and their purpose: IP Address - 192.168.1.112/24 Default Gateway - 192.168.1.1 DNS server - 192.168.1.1In order to set these up we will run the following commands:root@bt:~# ifconfig eth0 192.168.1.112/24root@bt:~# route add default gw 192.168.1.1root@bt:~# echo nameserver 192.168.1.1 > /etc/resolv.confThese settings however will only last until you reboot, so if we want to save them between reboots we need to edit the /etc/network/interfaces file like this:# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5). # The loopback network interface auto loiface lo inet loopback# The primary network interfaceauto eth0iface eth0 inet static address 192.168.1.112 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1Edit the file as appropriate, then have the network come up automatically at boot time:root@bt:~# update-rc.d networking defaultsroot@bt:~# /etc/init.d/networking restartIn order to get an IP from a DHCP server we can issue the dhclient
In order to get rid of this error you have to reboot Backtrack, than BEFORE starting WICD open up a terminal and type in the following:root@bt:~# dpkg-reconfigure wicdroot@bt:~# update-rc.d wicd defaultsNow after a reboot the error should not occur anymore.As you know Backtrack comes with a default username and password (root/toor) it is IMPORTANT that we change that root password especially when running services such as SSH. We can change the password by issuing the passwd command:root@bt:~# passwd Enter new UNIX password: {enter your new password here } Retype new UNIX password: {enter your new password again} passwd: password updated successfully root@bt:~#BackTrack has various services such as Apache, SSH, MySQL, VNC, etc. They are all disabled by default. To start a service such as SSH, you can use the service init scripts. For example, to start the SSH service:root@bt:~# sshd-generate # Specific to the SSH service - needed to generate SSH keysroot@bt:~# /etc/init.d/ssh startStarting OpenBSD Secure Shell server: sshd.root@bt:~# /etc/init.d/ssh stop Stopping OpenBSD Secure Shell server: sshd.root@bt:~# When using a ssh server for the first time on Backtrack you will need to generate keys:root@bt:~# sshd-generateTo enable a service at boot time, you can use the update-rc.d command, for example, having SSH start at boot time:root@bt:~# update-rc.d -f ssh defaults Adding system startup for /etc/init.d/ssh ... /etc/rc0.d/K20ssh -> ../init.d/ssh /etc/rc1.d/K20ssh -> ../init.d/ssh /etc/rc6.d/K20ssh -> ../init.d/ssh /etc/rc2.d/S20ssh -> ../init.d/ssh /etc/rc3.d/S20ssh -> ../init.d/ssh /etc/rc4.d/S20ssh -> ../init.d/ssh /etc/rc5.d/S20ssh -> ../init.d/sshroot@bt:~#apt-get install
