netmemo

Provides useful tips for Network & System administrators, to learners and also to curious folks :) NetMemo uses a library called "jnetparse" (see: https://github.com/cybconv/jnetparse) and to package NetMemo with all its dependencies within a single JAR I used an open source product called "OneJar" (see: http://one-jar.sourceforge.net/).

To rebuild NetMemo (on Windows):

• Install and launch Git Bash

• Clone NetMemo by issuing : git clone https://www.github.com/cybconv/netmemo

• Then issue the following commands in sequence: cd netmemo ./make.bat ./deploy.bat

• Then, to run NetMemo: java -jar netmemo.jar

  or you can double-click on netmemo.jar from your windows explorer.

Current NetMemo featues are:

• Cisco troubleshooting tips on:

  • IPv4/IPv6 Routing: BGP, OSPF, IS-IS and EIGRP
    • QoS & performances issues
    • MPLS
    • Multicasting
    • IP services
    • Switching
    • ...

• QoS:

  • mapping between DSCP & ToS values
  • mapping between DSCP & CoS values
  • mapping between DSCP & IP Precedence values

• IPv4/IPv6 addresses calculator

  • IPv6:
    • build different addresses

      link-local

      multicast

      EUI-64

      tunnels:

        | ISATAP
        | automatic 6to4
        | IPv4-mapped IPv6 addresses
        | automatic ipv4-compatible
      

• IP/MAC Multicast (MC) addresses mapping:

  • compute MultiCast MAC addresse from a MC IP address
  • given a MC IP address => show MC IP addresses that might cause MAC addresses collision

• Security:

  • generate pseudo-random passwords

• Helpers features to view networking configuration of your host

Enjoy :-)
