Net-SNMP



DEVELOPMENT


Extending Net-SNMP with

The NetSNMP::agent Perl module provides an agent object which is used to handle requests for a part of the agent's OID tree. The agent object's constructor has options for running the agent as a sub-agent of snmpd or a standalone agent. No arguments are necessary to create an embedded agent:
1:  use NetSNMP::agent (':all');  
2:  my $agent = new NetSNMP::agent();

The agent object has a register method which is used to register a callback function with a particular OID . The registerfunction takes a name, OID , and pointer to the callback function. The following example will register a callback function named hello_handler with the SNMP Agent which will handle requests under the OID . 1. 3. 6 . 1. 4 . 1. 8072. 9999 . 9999:
1:  $agent->register("hello_tester", ".1.3.6.1.4.1.8072.9999.9999",  
2:  \& hello_handler);

NOTE

The OID . 1. 3. 6 . 1. 4 . 1. 8072. 9999.9999 (NET -SNMP -MIB: : netSnmpPlaypen) is typically used for demonstration purposes only. If your organization does not already have a root OID , you can obtain one by contacting an ISO Name Registration Authority (ANSI in the United States).

DVWA - Brute Force (High Level) - Anti-CSRF Tokens

This is the final "how to" guide which brute focuses Damn Vulnerable Web Application (DVWA), this time on the high security level. It is an expansion from the "low" level (which is a straightforward HTTP GET form attack). The main login screen shares similar issues (brute force-able and with anti-CSRF tokens). The only other posting is the "medium" security level post (which deals with timing issues). For the final time, let's pretend we do not know any credentials for DVWA.... Let's play dumb and brute force DVWA... once and for all! TL;DR: Quick copy/paste 1: CSRF=$(curl -s -c dvwa.cookie "192.168.1.44/DVWA/login.php" | awk -F 'value=' '/user_token/ {print $2}' | cut -d "'" -f2) 2: SESSIONID=$(grep PHPSESSID dvwa.cookie | cut -d $'\t' -f7) 3: curl -s -b dvwa.cookie -d "username=admin&password=password&user_token=${CSRF}&Login=Login" "192.168.1

List of TCP and UDP port numbers

This is a list of Internet socket port numbers used by protocols of the transport layer of the Internet Protocol Suite for the establishment of host-to-host connectivity. Originally, port numbers were used by the Network Control Program (NCP) in the ARPANET for which two ports were required for half-duplex transmission. Later, the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. The even-numbered ports were not used, and this resulted in some even numbers in the well-known port number range being unassigned. The Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses. However, many unoff
