AIO Ident

Simple ident protocol (RFC 1413) parser for Python AsyncIO.

Install

It's just as simple as

pip install aioident

Doesn't require anything external as it only relies on standard modules.

Usage

It can connect to a host running an ident daemon.

import asyncio
import aioident

async def main():
    res = await aioident.connect("someone.sometld.com", 5912, 6667) # Assumes you are running at port 6667, and the remote host originates from port 5912 ( don't ask me, it's just some TCP sorcery ;) )
    # res = await aioident.connect("someone.sometld.com", 5912, 6667, 1113) # You can also use a different ident port if needed
    if res.ok and res.type == "UNIX":
        print(f"It works! Username: {res.username}")
    else:
        print(f"It doesn't work. Response: {res.type}")

asyncio.run(main())
# It works! Username: swee

It can also parse an ident response that has been already made.

import aioident

def test(text):
    try:
        res = aioident.parse(text)
        if res.ok:
            print(f"Is an ident response. Username is {res.username}")
        else:
            print(f"Is an ident response, but it failed. Error is {res.type}")
    except:
        print("That isn't an ident response.")

test("5912, 6667 : USERID : UNIX : swee") # Spaces are optional (not used in some identd software)
# Is an ident response. Username is swee

test("5912, 6667 : ERROR : NO-USER")
# Is an ident response, but it failed. Error is NO-USER

test("foo bar baz")
# That isn't an ident response.

Ident class

A simple class for parsing specific parts of the ident response (like checking statuses in requests)

This class is always returned with both aioident.connect and aioident.parse however it can also be built manually.

myident = aioident.Ident(5912, 6667, "USERID", "UNIX : swee") # straightforward building

myident.serverport # 5912

myident.clientport # 6667

# ^ It's easy to be confused with those two, but the "server" in this case is the identd listener.

myident.status # "USERID"

myident.data # "UNIX : swee"

# ^ Those four are the values already put in when building

myident.data_split # ["UNIX", "swee"], just splits the colons and automatically strips the spaces for each

myident.ok # True, Returns False if the status is ERROR and not USERID

myident.type # "UNIX", The type of username (usually UNIX) or the reason for error

myident.username # "swee", The username if successful and the type is UNIX. if both aren't true, then it will return None

myident.stringify # "5912, 6667 : USERID : UNIX : swee", Turns that class back into a string for a regular ident response

Example 2, with an error

myident = aioident.Ident(5912, 6667, "ERROR", "NO-USER") # still straightforward

myident.serverport # 5912

myident.clientport # 6667

myident.status # "ERROR"

myident.data # "NO-USER"

myident.data_split # ["NO-USER"]

myident.ok # False

myident.type # "NO-USER"

myident.username # None

myident.stringify # "5912, 6667 : ERROR : NO-USER"
