# vudu v0.2 - Unix X.25 NUA Scanner
# Copyright (c) 2001 Raptor <raptor@0xdeadbeef.eu.org>
#
# Vudu is a simple X.25 NUA scanner for Unix systems: his
# main goal is portability, so it's written in bourne shell
# scripting language, without fancy stuff. Remember to change 
# the vars to suit your operating system's needs. 
# FOR EDUCATIONAL PURPOSES ONLY.
#
# Tested mainly on Solaris. Thanks to Sentinel for his _old_ code.
#
# Usage example: ./vudu 0208057040 535 542 [who can forget QSD? :)]
#


# Some vars (change them if needed)
tmp=vudu.tmp
valid=vudu.nua
pad=./pad

# Response codes (optimized for Sun pad)
com=Connected
dte=DTE
der="Out Of Order"
rpe="Remote Procedure Error"
na="Access Barred"
occ="Number Busy"
