Proper init script

[severeski]

Ok guys,

First off vysheng I really love this this project so I decided to pitch in.

I wrote a proper init script for deamon mode telegram-cli (i hope;) )

There still are some quirks but I can tweak etc all I want but I decided to put it out here so I can get some propper feedback. Seemed more usefull to me.

The script is based for use on raspbian (raspberry pi debian wheezy).

First the files:

/etc/init.d/telegram-cli

#! /bin/sh
### BEGIN INIT INFO
# Provides:          telegram-cli
# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Commandline interface for Telegram chat program
# Description:       Telegram-cli is a (unofficial) cli version of Telegram to chat from your console.
#                    This is an init script do make it a daemon.
#                    When used as daemon in conjuction  with LUA (scripting) you can use it to send your system
#                    commands to execute via other Telegram apps (PC - Phone - Web or other) while not
#                    logged in to the system.
#
#                    Note #1: This version of the init script is developed for raspbian (rapberry PI port of Debian Wheezy).
#
#                    Note #2: Change the ¨DAEMON=¨ var to match your installation path of telegram-cli
#
#                    See: https://github.com/vysheng/tg for more information.
### END INIT INFO

case "$1" in

    start)
        echo -n "Starting $DESC ... "
        start-stop-daemon --start --background --make-pidfile $PIDFILE --pidfile $PIDFILE \
            --exec $DAEMON -- $OPTS || true
        echo "Done."
    ;;

    stop)
        echo -n "Stopping $DESC ... "
        start-stop-daemon --stop --retry 2 --pidfile $PIDFILE \
            --exec $DAEMON || true

        start-stop-daemon --stop --retry 2 --pidfile $PIDFILE \
            --exec $DAEMON || true
        start-stop-daemon --start --background --make-pidfile $PIDFILE --pidfile $PIDFILE \
            --exec $DAEMON -- $OPTS || true
        echo "Done."
    ;;

    status)
        status_of_proc -p $PIDFILE $DAEMON $NAME && exit 0 || exit $?
    ;;

    *)
        N=/etc/init.d/$NAME
        echo "Usage $NAME: /etc/init.d/telegramd {start|stop|restart|status}"
        exit 1
    ;;

esac

# Note: use the -R -C option if you want to write to log file. Otherwise it will just print garbage.

OPTS="-W -U pi -G pi -s <path_to_lua_script>/test.lua -P 1234 -d -L /var/log/telegram-cli.log -vvvRC"

:Some notes to get it working correctly (I wrote comments on it in the files themself as best as I could but to be sure):

The idea is the following:

/etc/telegram-cli/server.pub holds your server.pub key for which the program searches on startup. Available in source dir after gt checkout.

/etc/default/telegram-cli holds all the config options. The included sample code is kinda example enough by it's self ;)

/etc/init.d/telegram.cli (the actual init script) Important is to change the "DAEMON=" to the directory you have you're install of the telegram-cli program.

Work in progress is /var/log/telegram-cli.log file. For now I created it by hand an gave it world read write permission till i work out how to properly create one.

1. Most important is to change the "DAEMON=" parameter in /etc/init.d/telegram-cli file to your installation of telegram-cli program.

2. It is forced run with username 'pi' for now. This can be any other user kinda depends on under which user you registered telegram-cli under..

3. To make it run on boot when you are registered do:

update-rc.d -f telegram-cli defaults

4. it create's a TCP port 1234 to give it commands via netcat or telnet via localhost or other. See: https://github.com/vysheng/tg/wiki/Running-as-daemon scroll to end of the post for an example.

5. You need to register a different phone number then you own to make LUA scripting work!!! That drove nuts while fucking arround with it. I just registered my parents mobile number cause they do jack shit with their mobile. Let alone telegram ;P

6. If you want to run it as daemon you need a real homedir/login and run it once interactively to register your number and write the proper ~/.telegram-cli files. You can also copy those files from another user it seems. Up to you :)
   Do not ry to backspace or anything it will mostly give you crap. just (country code) + (number) example for NL users: +310612345678 (you can ommit the 0 btw 0 ;) )

/<your install dir>/telegram-cli -W -k /<your dir>/tg-server.pub

This can take some time the first time, so be patient. Register you phone and type the code you get via sms/or phone call.

Then type

safe_quit

And ya are good to go ...
For me this works like a charm.

I would really like to have some feedback on how to make certain things more generic and/or trouble you run into or anything other.

Cheers!

When installing on centos 6 i noticed i don't have the script start-stop-daemon. Also /lib/init/vars.sh was missing. So, i modified the init.d-script a bit Here it is:
First, the defaults-script in /etc/default:

OPTS="-W -dL /var/log/telegram-cli.log -vvvvRC -k /etc/telegram-cli/server.pub -P 1234"

And here is the init.d script:

#! /bin/sh ### BEGIN INIT INFO
# Provides: telegram-daemon # Required-Start:
# Required-Stop: # Default-Start: S 2 3 4 5
# Default-Stop: 0 6 # Short-Description: telegram daemon
# Description: telegram daemon ### END INIT INFO
# Author: fizzzel # actions
case "$1" in
start)
echo "Telegram daemon is starting..."
su telegramd -c '/usr/bin/telegram-cli -vvvvRC -k /etc/telegram-cli/server.pub -W -dL /var/log/telegram-cli.log -P 1234 &'
echo "...done"
;;
stop)
echo "stopping telegram daemon..."
sudo pkill -9 telegram-cli
echo "..done"
;;
restart)
echo "stopping telegram daemon..."
sudo pkill -9 telegram-cli
echo "..done -- restarting..."
su telegramd -c '/usr/bin/telegram-cli -vvvvRC -k /etc/telegram-cli/server.pub -W -dL /var/log/telegram-cli.log -P 1234 &'
echo "...done"
;;
esac

exit 0

`

This works, i have now 2 servers running this 24/7.
To make this work, first make sure that everything is in place: telegram-cli in /usr/bin, server.pub in /etc/telegram-cli and OPTS-line mentioned earlier in /etc/default/lelegram-cli. Then create a user telegramd. then do a su - telegramd and run telegram-cli manually. Fill in phone number and receive SMS-code. Fill it in. As said, you can also copy the /.telegram-cli folder from somewhere else, provided you know the number it is connected to. Send a msg to yourself to test. Then type quit. Then you can start it as a daemon using service telegram-cli start.

Good luck.
