Open Source Router Firmware - Page 2

The project is implemented as part of the CS-110 operating system course at IIIT Bangalore 2013. Aodv protocol is implemented on GPU using CUDA 4.0. A significant gain in execution time is observed when compared to CPU. Thus a simulator which uses GPU can be built on similar lines of NS2 if all the protocols can be parallelized and implemented on GPU.

A Java implementation of a NAT-PMP client. At the project's inception, there was not a well-known NAT-PMP client library for Java. This project intends to fill the gap.

Tiet reads pcap(3) or argus(8) routing protocol traces (ISIS for now) and analyzes the protocol state/behavior. The obtained metrics & graphics can by used for many auditing tasks, e.g. detection of misconfiguration, bugs or performance problems.

Python script for pushing the same configuration (stored in a predefined file) on multiple devices at the same time via SSHv2. The script reads the IPs of the devices from the NETWORK_IP file, then gets the SSHv2/Telnet credentials from the SSH_USERPASS file and sends the commands you enter in the CMD_FILE file to all the devices. The script also checks if all the needed files exist, if all the IP addresses are valid and if all the devices are reachable. Tools used: Python 2.7.3, GNS3, Linux.

Python script for pushing the same configuration (stored in a predefined file) on multiple devices at the same time via Telnet. The script reads the IPs of the devices from the NETWORK_IP file and sends the commands you enter in the CMD_FILE file to all the devices. Telnet username/password parameters are configured within the script. This feature can be further customized to prompt the user for them or read them from a file. The script also checks if all the needed files exist, if all the IP addresses are valid and if all the devices are reachable. Tools used: Python 2.7.3, GNS3, Linux.

NetMon_Cisco_to_SQL.py is a basic network performance monitoring and logging script for Cisco devices. It gathers parameters (CPU Utilization, Used Processor Memory, Used IO Memory, UP Ethernet Interfaces density, in percent velues) from Cisco routers by parsing command outputs and exports them to a MySQL database. NetMon_Query.py is a query script for the MySQL database in the form of an interactive menu for generating statistics. Tools used for coding and testing: Python 2.7.3, MySQL Server 5.5.37, GNS3, Linux. Tested on Cisco 1710, 2621, 2691, 3660, 3725, 7206

OSPF_SNMP_v1.0.py is an OSPF network discovery script. It allows the discovery of all OSPF network devices in the network, without connecting to each of them or knowing all their IP addresses. The user must provide the IP and SNMP community string of a single OSPF device in the network (for example, a device in the core) and the script searches for all other OSPF routers. Prior to running the script, the user should configure SNMPv2 community string on the device and also include the subnet between his PC and the router into the OSPF process, so he has IP connectivity to all other OSPF nodes. After providing necessary info and the OSPF info is gathered, the user has three choices: display the OSPF routers info on the screen, export the data to a file for Excel importing and generate the OSPF topology showing neighborships, router IDs and neighbor IPs. Tools used for coding and testing: Python 2.7.3, PySNMP, GNS3, Linux. Tested on Cisco 2621, 2691, 3660.
