### Linking services with a Telegram bot

 

#### Creating a Telegram Bot

1. In Telegram, look for '@BotFather'
2. Initialise with `/start`
3. Create bot with `/newbot`

Record the Token from the message from *BotFather*.

 

#### Getting the Bot's Chat ID

In a terminal, run:

```ad-command
title: Telegram Chat ID
~~~bash
curl https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | jq .message.chat.id
~~~
```


 

#### Linking Logwatch

Please see full documentation [[GitHub - fxkjdlogwatch-telegram-bot Send logwatch results to your telegram account|here]].

 

#### Linking monit

Please see full documentation [[GitHub - matriphemonit2telegram A simple script to send Monit alerts using Telegram bot.|here]].

 

#### Linking fail2ban

Please see full documentation [[GitHub - deividgdtfail2ban_telegram_notifications Sending fail2ban notifications using a Telegram bot|here]] for SSH monitoring.

##### Postfix Monitoring

In order to monitor SMTP connections through Fail2Ban, a few steps need to be taken.

1. Open the conf file

```ad-path
~~~bash
/etc/fail2ban/jail.conf
~~~
Or
~~~bash
/etc/fail2ban/jail.local
~~~
```

 

2. Edit Postfix & create Postfix-auth

```ad-code
~~~bash
[postfix]

enabled = true
maxretry = 3
bantime = 1h
filter = postfix[mode=aggressive]
	telegram
mode    = more
port    = smtp,465,submission
logpath = %(postfix_log)s
backend = %(postfix_backend)s

[postfix-auth]
enabled  = true
bantime  = 1h
filter   = postfix.auth
action   = iptables-multiport[name=postfix, port="http,https,smtp,submission,pop3,pop3s,imap,imaps,sieve”, protocol=tcp]
        telegram
logpath  = /var/log/mail.log
ignoreip = 127.0.0.1/8
maxretry = 3
~~~
```

 

3. Create postfix.auth filter

```ad-path
/etc/fail2ban/filter.d/postfix.auth.conf
```

 

```ad-code
~~~bash
[Definition]
failregex = lost connection after AUTH from (.*)\[<HOST>\]
ignoreregex =
~~~
```

&emsp;

4. Restart fail2ban

```ad-command
~~~bash
sudo systemctl restart fail2ban
~~~
```
