Netzkarte als .dot-Datei ausgeben mit olsrd-plaintext-plugin

  • speichern als /www/cgi-bin-map
  • beim aufruf wird direkt die datei heruntergeladen, danach:
  • neato -Goverlap=scale -Gsplines=true -Gstart=3 -v -Tpng -o karte.png karte.dot
  • GraphViz / Neato - Anleitung: http://www.graphviz.org/pub/graphviz/CURRENT/doxygen/html/classes.html
  • Handarbeit / Nacharbeit ist manchmal notwendig. (Nodes stehen noch in /etc/hosts, aber im OLSR nicht mehr etc.)
  • ToDo:
    • kumulieren der ETX-Werte ueber einen groesseren Zeitraum -> Durchschnittsbildung
    • Bandbreite anstatt ETX-Wert visualisieren
    • GPS-Daten miteinbeziehen
  • Zum ausprobieren: http://entoro.homelinux.net/cgi-bin-map

# This script generates helpful infos about your fff-openwrt-router
# Its main purpose was to avoid loading hundreds of kilobytes from
# slow longrange wireless-links only to get some infos.
# Output is HTML,but human AND machine-readable & ~1500 bytes.
#
# ToDo:
# - determine exact hardware type from board values ("wrt54gs v1.1")
# - determine runtime and memoryusage for each task
# - reduce memoryusage / speedups
#
# Features: http://.../cgi-bin-info.html?OPTION ,where OPTION can be:
# n        -> normal mode,precalculated page
# m=600    -> (not yet!) changes looping of precalculated page to 600 seconds
# l        -> livedata
# L        -> list all nodes
# f        -> freemem
# o        -> opensource of this script
# O        -> override low_txpwr
# R        -> force 11mbit
# g        -> only gpsdata+location
# c        -> collect gpsdate from all nodes
# M=23     -> paint SVG-map from hole network (max 23 hops away)
# m        -> version of weimarnetz-macliste
# b        -> Baraucke-Mode: get MAC-list from Kraska/Funkstelle
# j        -> jens-modus, Alle aktiven Netzknoten + Nachbarn + ETX werte
# J        -> jens2-modus, alle verbindungen
# C        -> jens2-modus, aber nur verbindungen des Abfragenden
# H        -> Alle Interneteinspeiser, nur Netzknotennummer
# W        -> prints WEIMARNETZ-version
# G        -> (not yet!) collect from all nodes gps-info
# k        -> (not yet!) outputs SVG-map of actual mesh
# s        -> starts oder ends SSHd / dropbear
# A        -> ARPspy, prints /proc/net/arp
# PhIP     -> tracepath/traceroute to IP with h=max_hopcount
# pIP      -> ping IP six times
# d=345    -> download of 345kb trash
# D=567    -> downloads from you 567kb trash
# a        -> (not yet!) allow/disallow download
# i        -> lists installed software
# r        -> print syslog
# rChild   -> print syslog and grep "Child"
# r-v MARK -> print syslog,except lines with "MARK"
# wMESSAGE -> inject message into routers syslog
