Thats it.

Purpose

If you have ever installed the snmpd package for Debian or Ubuntu and wondered why it did not bind to all active interfaces no matter what configuration you have, here is the solution.

Procedures

1. You need to modify the “/etc/defaults/snmpd” file and remove the reference to 127.0.0.1 in the startup command to allow it to fall back to defaults. This was put in as a security measure, but there are very valid reasons to remove it.
2. Change the following in the “/etc/defaults/snmpd” file.

SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1′

SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid’

Purpose

If an 802.11 wireless network ever employs a MAC access list, this is a simple solution for easily defeating this terrible security measure. This already assumes you have BackTrack loaded and a wireless card capable of monitor mode.

Procedures

1.  In a terminal brought up the wireless interface, and turn on airmon as show in Figure 1

Figure 1: Starting card up in monitor mode.

2. Started airodump-ng to collect a valid MAC address of a collected client as seen in Figure 2.

Figure 2: Locating an assocated station to mimic.

3.  Copy out a valid MAC address and apply it to the the current wireless interface as seen in Figure 3.

Figure 3: Mimic the stolen station MAC address.

4. Use this wireless interface to associate to the MAC filtering network with success. If you experience intermittent connection issues, this is because you are sharing a MAC address with another associated client and this can cause unexpected results.

Grey block quote is a command typed directly into the console.

Procedures

1. Log in as root or an administrative user.

#apt-get install tftpd
#mkdir /tftpboot
#chmod 777 /tftpboot

2. Edit /etc/inetd.conf, change /srv/tftp to /tftpboot under the tftp section. This is a matter of personal choice, however many programs use the /tftpboot directory as their base of operations for TFTP transactions.
