This packet was taken from a packet sniffer that monitors a Web server. 

This packet was originally 1514 bytes long, but only the first 512 bytes are shown here. This is the standard hexdump representation of a network packet, before being decoded. A hexdump has three columns: the offset of each line, the hexadecimal data, and the ASCII equivalent. This packet contains a 14-byte Ethernet header, a 20-byte IP header, a 20-byte TCP header, an HTTP header ending in two line-feeds (0D 0A 0D 0A) and then the data. By examining the packet identify the name and version of the Web server? 

A. Apache 1.2 

B. IIS 4.0 

C. IIS 5.0 

D. Linux WServer 2.3

Q6. Study the following exploit code taken from a Linux machine and answer the questions below: 

echo “ingreslock stream tcp nowait root /bin/sh sh –I" > /tmp/x; 

/usr/sbin/inetd –s /tmp/x; 

sleep 10; 

/bin/ rm –f /tmp/x AAAA…AAA 

In the above exploit code, the command “/bin/sh sh –I" is given. 

What is the purpose, and why is ‘sh’ shown twice? 

A. The command /bin/sh sh –i appearing in the exploit code is actually part of an inetd configuration file. 

B. The length of such a buffer overflow exploit makes it prohibitive for user to enter manually. The second ‘sh’ automates this function. 

C. It checks for the presence of a codeword (setting the environment variable) among the environment variables. 

D. It is a giveaway by the attacker that he is a script kiddy.
