==Networking==
https://git.xpub.nl/kamo/bot-magic-words


🟣 = a device (server/laptop/phone/...)
🟡 = a network


We will go through the following commands from 🟣 sergio.
==the zulip bot==


So the first step is to log into 🟣 sergio:
First install the requirements listed on this page:  


ssh sergio
https://zulip.com/help/writing-bots


To which networks is 🟣 sergio connected right now?
You can run the bot with:


  ip a
  zulip-run-bot --config-file bootlegbot.zuliprc bootlegbot.py


To which networks is 🟣 the bootleg library connected right now?
(or <code>uv run zulip-run-bot --config-file bootlegbot.zuliprc bootlegbot.py</code> if you are using uv)

Is 🟣 sergio part of the same network as 🟣 the bootleg library is?
<syntaxhighlight lang="python">
class BootlegBot(object):
    '''
    This is a small zulip bot to interact with the 👢🦵 library
    '''


...
    def usage(self):
        return '''Ask the bot about a book and they will search for it in the 👢🦵 library'''


How can we check if we can communicate with 🟣 the bootleg library through this network?
    def handle_message(self, message, bot_handler):
        # This happens when someone write to the bot


ping ip-address
        sender = message['sender_full_name']
        content = message['content']
        print(f'{sender} wrote to the bot: "{content}"')


Let's first check 🟡 the XPUB HUB (see all HUB servers listed [[HUB|here]])
handler_class = BootlegBot
</syntaxhighlight>


ping 10.0.0.103
===bootlegbot.zuliprc===


Who else is on 🟡 the HUB network right now?
<pre>
 
[api]
nmap 10.0.0.*
email=bootleg-bot@zulip.xpub.nl
 
key=XXXXXXXX
And who else is on 🟡 eduroam right now? (in the same subnet)
site=https://zulip.xpub.nl
 
</pre>
nmap 145.24.152.*
 
Can we reach 🟣 the bootleg library through 🟡 eduroam?
 
ping 145.24.153.55
 
We can make such a mapping because we are part of the same LAN network.
 
LAN = local area network
 
Let's take a short side step.
 
We want to make a zulip bot. Which network do we use everyday to connect to 🟣 the XPUB zulip server?
 
ping zulip.xpub.nl
<check your ip address from your device>
 
How does such a zulip connection travel?
 
traceroute zulip.xpub.nl
 
We can trace this route because all the "hops" are done on 🟡 the public internet (the WAN).
 
WAN = wider area network, aka the internet
 
So to summarize, these devices are part of the following networks:
 
🟣 bootleg library: 🟡 10.0.0.103 + 🟡 145.24.153.55
🟣 sergio:
🟣 your laptop:
🟣 XPUB zulip server:
 
With an important footnote: we're not sure if it was intentional to have 🟣 the bootleg library on 🟡 eduroam. So let's keep in mind that we will most likely loose this connection.
 
Which 🟣 device can we use to run a bot that connects the 🟣 XPUB zulip server to 🟣 the bootleg library (on 🟡 the HUB), keeping in mind that the whole goal of this is to connect to 🟣 the bootleg library from 🟡 the WAN?
 
...
 
How can we connect 🟣 our device (on 🟡 WAN) to 🟣 sergio (on 🟡 eduroam + 🟡 HUB) to connect to 🟣 the bootleg library (on 🟡 eduroam + 🟡 HUB)?
 
in many ways...
 
But which option will we focus on today?
 
SSH tunnelling!
 
==SSH tunnelling==
 
https://ittavern.com/visual-guide-to-ssh-tunneling-and-port-forwarding/
 
(After having written this... I think we need to simplify this step and only use the xpub user on sergio...)


From your device, ssh into the bootleg library using a SSH tunnel:
We need to share the key with each other somehow.


ssh -J sergio pi@10.0.0.103
===Zulip bot API===


From $ man ssh:
https://zulip.com/help/interactive-bots-api


-J destination
==hello Python!==
 
Connect to the target host by first making a ssh connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive.


===Install your SSH key on the bootleg library===
see: [[Hello Python]]


If you get a "publickey denied" error, you need to install a SSH key of your user on sergio to the bootleg library.
==SSH to bootleg library==


First generate a SSH key.  
There are two ways in which we can do this.


ssh-keygen -t ed25519
===laptop > sergio > bootleg library (from outside the school)===
 
Find the public key:
 
cd .ssh
cat id_ed25519.pub
 
Copy the output.
 
Log in to the bootleg library with the xpub user on sergio:


  ssh sergio
  ssh sergio
  sudo su - xpub
  sudo su - xpub
  sudo pi@10.0.0.103
  ssh pi@10.0.0.103


This works, and without password, because the SSH keys of xpub@sergio are already installed at pi@bootleglibrary.
===laptop > bootleg library (on eduroam)===
ssh pi@145.24.153.55


Move to the .ssh folder:
==read database==


cd .ssh
* Simon and Luke made this Python script in 2021, to make the temporary index cards: https://git.vvvvvvaria.org/simoon/temporary-indexing

Open the authorized keys file:
==write to database==


nano authorized_keys
* a standalone webform for file uploads

* hosted on sergio (but can be hosted on another sandbox too in the future)

This page is prepared for the prototyping class on 3 March 2026 as part of SI29 and follows a Special Issue day with Doriane and Simon fully on topic of The bootleg library.

https://git.xpub.nl/kamo/bot-magic-words


the zulip bot

First install the requirements listed on this page:

https://zulip.com/help/writing-bots

You can run the bot with: 

zulip-run-bot --config-file bootlegbot.zuliprc bootlegbot.py

(or uv run zulip-run-bot --config-file bootlegbot.zuliprc bootlegbot.py if you are using uv)

bootlegbot.py

class BootlegBot(object):
    '''
    This is a small zulip bot to interact with the 👢🦵 library
    '''

    def usage(self):
        return '''Ask the bot about a book and they will search for it in the 👢🦵 library'''

    def handle_message(self, message, bot_handler):
        # This happens when someone write to the bot

        sender = message['sender_full_name']
        content = message['content']
        print(f'{sender} wrote to the bot: "{content}"')

handler_class = BootlegBot

bootlegbot.zuliprc

[api]
email=bootleg-bot@zulip.xpub.nl
key=XXXXXXXX
site=https://zulip.xpub.nl

We need to share the key with each other somehow.

Zulip bot API

https://zulip.com/help/interactive-bots-api

hello Python!

see: Hello Python

SSH to bootleg library

There are two ways in which we can do this.

laptop > sergio > bootleg library (from outside the school)

ssh sergio
sudo su - xpub
ssh pi@10.0.0.103

laptop > bootleg library (on eduroam)

ssh pi@145.24.153.55

read database

write to database

  • a standalone webform for file uploads
  • using the bootleg library upload URLs
  • hosted on sergio (but can be hosted on another sandbox too in the future)
