Some useful random libraries and scripts used in my Raspberry Pi servers.

Config file

  • This library use ConfigParser compatible format.

  • The config file is hard coded to be at '$HOME/.llpi.cfg', which is the only file needed to be customized to make this work.

  • The config file is read by 'pylib/llnet' and 'scripts/tweet_ip'.

  • An example of config file

[general]
LLPI_ROOT_PATH = /home/pi/llpi


[twitter_app1]
APP_KEY = xxx
APP_SECRET = xxx
OAUTH_TOKEN = xxx
OAUTH_TOKEN_SECRET = xxx

[tweet_ip]
TWITTER_APP = twitter_app1
NETWORK_INTERFACE = wlan0
  • This library depends on user environmental variables. When using the script with crontab, source the BASH profile first to set up the environmental variables correctly:
0 5 * * * source $HOME/.profile; /path/to/command/to/run

Use Cases

  • Case 1: push IP address to Twitter
import sys
import socket
import llnet as net

tw = net.Twitter('twitter_app1')
time_ntp = net.get_time_ntp()
hostname = socket.gethostname()

msg = "[%s] %s: active at %s" % (time_ntp, hostname, net.get_ip_address("wlan0"))

tw.update_status(msg)
