What the script do
The script will do the following
-
listen for any command send by the admin and run it as a shell command
-
Only admin can send command. Verification is done by checking sender username, user id and a simple password.
-
Any message received by unknown sender will be ignored.
-
syntax: " "
- e.g: "mypassword ifconfig -a"
-
-
Periodically send "i am alive" message to admin.
- Telegram Bot has no online/offline status, so i simply ask the bot to tell me if it is still alive every few minutes.
Pre-requisites
-
Register your Telegram Bot and obtain the token
-
set the bot to accept inline command using "/setinline"
-
start the bot
-
Install the following modules
# pip install -r requirements.txt
Optional Steps
To make sure the script is started during power-on and auto-restarted if it crash for any reason. One of the option is using systemd
Using systemd
-
copy the same unit file
$ cp serverbot.service /etc/systemd/system/serverbot.service -
adjust the unit file
-
enable and start the bot
# systemctl enable serverbot # systemctl start serverbot
Limitation
- The script currently only support direct chat.
- It can be improved to have a callback mechanism so multiple user can interact with the bot at the same time, and we can include the bot into a telegram group.
- The security is very minimum right now, it only check if the sender ID and username match to a specific value and the passcode (which is the first word of the received message) is matched.
- Potential improvement:
- hash the password value
- support multiple admin
- ...
