listen & print Cisco CDP through tcpdump or snoop
#!/usr/bin/perl -w
# Listen for Cisco Discovery Protocol (CDP) packets
# and print out key values such as switch, port and vlan.
# This script depends on either "snoop" (Solaris) or
# "tcpdump" (Linux, AIX, and others). Both of those programs generally
# must be run as root.
# It has been tested on Solaris 10 and Linux (CentOS, Ubuntu)

vim-enhanced configuration
View vimrc
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.
" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
