Usando profanity.

1️⃣ Install a CLI XMPP client

Popular CLI clients:

We’ll use profanity here — easiest for first-time setup.

2️⃣ Start profanity

profanity

You’ll enter the interactive CLI:

profanity v0.xx
Type /help for commands
>

3️⃣ Create an account (in-band registration)

Inside profanity:

/account add

It will prompt:

Username: yourusername
Domain: creep.im
Password: <choose a strong password>
Resource [optional]: CLI

• Resource: optional; identifies this session (like CLI or laptop).
• The client will attempt in-band registration on creep.im.
• If successful, your account is created instantly.

⚠️ If it fails, check that port 5222 is reachable (nc -vz creep.im 5222) and retry.

4️⃣ Select and enable your account

After creation:

/account list
/account use yourusername@creep.im

Then connect:

/connect

You should see:

Connecting to creep.im:5222...
Connected!

5️⃣ Sending a message

/msg friend@creep.im Hello from CLI!

• Replace friend@creep.im with the recipient’s JID.
• You can also start a chat session:

/chat friend@creep.im

Type messages normally; they are sent on Enter.

6️⃣ Receiving messages

• Incoming messages automatically appear in the terminal.
• To check online users:

/roster

7️⃣ Disconnect

/disconnect
/quit

8️⃣ Optional: Enable OMEMO encryption

/omemo start

• Profanity supports OMEMO (end-to-end encryption) if both clients support it.
• You can verify device IDs and trust your contacts via /omemo list.

9️⃣ Debugging connection issues

From your shell:

# Check SRV records (XMPP standard)
dig +short _xmpp-client._tcp.creep.im SRV

# Test TCP port
nc -vz creep.im 5222

# Test TLS handshake
openssl s_client -connect creep.im:5222 -starttls xmpp

If these fail, the client won’t be able to connect.

✅ Summary of basic workflow

profanity
/account add           # create account
/account use user@creep.im
/connect
/msg friend@creep.im Hello from CLI!
/disconnect
/quit

Perfect! We can set up profanity fully from the command line so you can register, connect, and even send a first message automatically. Here’s how to do it on Arch Linux.

1️⃣ Install profanity

sudo pacman -S profanity

2️⃣ Prepare a simple configuration file

Profanity can read commands from a file. Let’s create one:

nano ~/.profrc

Add:

# Profanity auto config
account add yourusername@creep.im yourpassword CLI
account use yourusername@creep.im
connect

• Replace yourusername with your desired username.
• Replace yourpassword with a strong password.
• CLI is the resource name; can be anything (e.g., laptop, phone).

Save and exit (Ctrl+O, Enter, Ctrl+X).

3️⃣ Run profanity in batch mode to auto-connect

profanity -c ~/.profrc

• Profanity will:

  1. Add your account (in-band registration on creep.im)
  2. Use the account
  3. Connect to the server

4️⃣ Send a message automatically

You can add a message command to the config file:

# ~/.profrc
account add yourusername@creep.im yourpassword CLI
account use yourusername@creep.im
connect
msg friend@creep.im Hello from CLI!

• Replace friend@creep.im with the recipient JID.
• When you run profanity -c ~/.profrc, it will connect and send that message automatically.

5️⃣ Optional: Run in non-interactive mode

If you want fully automated scripts, you can do:

echo "/account add user@creep.im password CLI
/account use user@creep.im
/connect
/msg friend@creep.im Hello from CLI!" > /tmp/profanity_commands.txt

profanity -c /tmp/profanity_commands.txt

6️⃣ Notes & tips

• In-band registration must be allowed on the server (creep.im supports it).
• If registration fails, check TCP port:

nc -vz creep.im 5222

• You can enable OMEMO encryption in CLI later:

/omemo start
/omemo list
