# Identd Setup

From ArchWiki

The Ident service as specified by RFC 1413 is mostly used by various IRC networks and the occasional old FTP server to ask a remote server which user is making a connection. This method is quite untrustworthy, as the remote host can simply choose to lie.

So you have two choices:

1. Tell the truth (see pidentd below)
2. Tell a little white lie (see nullident below)

## pIdentd

Like most people, I prefer to run identd from from inetd instead of as a stand-alone service. For this to work you will need to install two packages: xinetd and pidentd. I tried this with oidentd but it does not seem to work with the latest xinetd.

1. Install xinetd and pidentd.

2. Next, you will need to paste the following into a new file and save it as `/etc/xinetd.d/auth`

    service auth
    {
          flags = REUSE
          socket_type = stream
          wait = no
          user = nobody
          server = /usr/bin/identd
          server_args = -m -N
          logonfailure += USERID
          disable = no
    }

3. After you have saved the new file, start xinetd systemd service.

If all went well, you should have the auth service running on port 113. A good way of checking this is by installing nmap (if you do not have it already) and typing

    $ nmap localhost
