# You need to setup ssh-keys to avoid password prompt, see url how-to setup
# ssh-keys:
# cyberciti.biz/nixcraft/vivek/blogger/2004/05/ssh-public-key-based-authentication.html
#
# [1] You need to setup correct VARIABLES script:
#
# (a) Change Q_HOST to query your host to get information
# Q_HOST="192.168.1.2 127.0.0.1 192.168.1.2"
#
# (b) Setup USR, who is used to connect via ssh and already setup to connect
# via ssh-keys
# USR="nixcraft"
#
# (c)Show warning if server load average is below the limit for last 5 minute.
# setup LOAD_WARN as per your need, default is 5.0
#
# LOAD_WARN=5.0
#
# (d) Setup your network title using MYNETINFO
# MYNETINFO="My Network Info"
#
# (e) Save the file
#
# Please refer to forum topic on this script:
# Also download the .gif files and put them in your output dir
#
# ----------------------------------------------------------------------------
# Execute script as follows (and copy .gif file in this dir) :
# this.script.name > /var/www/html/info.html

# SSH SERVER HOST IPS, setup me
# Change this to query your host
Q_HOST="172.31.1.21"
# SSH USER, change me
USR="root"
# Show warning if server load average is below the limit for last 5 minute
LOAD_WARN=5.0
# Your network info
MYNETINFO="My Network Info"
#
# if it is run as cgi we can do reload stuff too :D
