# Plugin made by Dju
|
||||
# useful to know your freebox uptime, and to see when it has rebooted ;)
|
||||
#
|
||||
# Uses nmap to get the uptime (by tcp connection, RFC1323)
|
||||
# ports usually opened on the freebox: 80 554 9100
|
||||
#
|
||||
# ----------------------------------------------------------------------------------------------------
|
||||
# nmap example with the -O option
|
||||
# on a freebox v5
|
||||
#
|
||||
# Starting Nmap 4.62 ( http://nmap.org ) at 2010-12-17 02:25 CET
|
||||
# Interesting ports on mafreebox.freebox.fr (212.27.38.253):
|
||||
# Not shown: 1712 filtered ports
|
||||
# PORT STATE SERVICE
|
||||
# 80/tcp open http
|
||||
# 554/tcp open rtsp
|
||||
# 9100/tcp open jetdirect
|
||||
# Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port
|
||||
# Device type: remote management
|
||||
# Running: HP embedded
|
||||
# OS details: HP Onboard Administrator management console
|
||||
# Uptime: 7.226 days (since Thu Dec 9 21:01:44 2010)
|
||||
#
|
||||
# OS detection performed. Please report any incorrect results at http://nmap.org/submit/ .
|
||||
# Nmap done: 1 IP address (1 host up) scanned in 29.279 seconds
|
||||
# ----------------------------------------------------------------------------------------------------
|
||||
#
|
||||
# by using nmap on a specific tcp port, the detection is pretty fast (2-5 seconds)
|
||||
# with this command: nmap -O --osscan-guess -p80 remote_host
|
||||
#
|
||||
# if you dont want nmap to query your freebox each time, set CACHE_HOURS=n
|
||||
# to keep the uptime in cache for n hours
|
||||
# if not, set CACHE_HOURS=0
|
||||
#
|
||||
# to allow this plugin to use nmap, edit /etc/munin/plugin-conf.d/munin-node and add

config (required)
|

autoconf (optional - used by munin-node-configure)
