First, find out which is the encrypted LVM partition

cat /etc/crypttab

To add a new password, use luksAddKey:

sudo cryptsetup luksAddKey /dev/sda3

To remove an existing password, use luksRemoveKey:

iAnatoly

#!/usr/bin/env python3
import socket
import time
 
userid = "trivial_sip_pinger"
domain = "<sip server to test>"
port = 5060
timeout_ms = 1000
 
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

1. Create a file with json request, for example:

$ cat > TTS.json <<END
{
  "audioConfig": {
    "audioEncoding": "LINEAR16",
    "pitch": 0,
    "speakingRate": 1
 },

1. create bot by messaging @botfather (/newbot)
2. save a token in env var: export token="yourtokenfrombotfather". If you need to re-issue a token, use /revoke command to botfather.
3. add your bot to a channel you intend for alerts
4. Send some message into that channel using telegram client. A simple "test" will do.
5. get chat id: curl https://api.telegram.org/bot${token}/getUpdates | grep test
6. send a test message: curl https://api.telegram.org/bot${token}/sendMessage --data '{"chat_id":${chat_id},"text": "message"}' -H "Content-type: application/json"
7. codify the above experience.
