# ident(3tcl)

Ident protocol client

```

```

## NAME

ident - Ident protocol client

## SYNOPSIS

package require **Tcl 8.5 9**

package require **ident ?0.44?**

**::ident::query** *socket* ?*callback*?

```

```

## DESCRIPTION

The **ident** package provides a client implementation of the ident protocol as defined in RFC 1413 (*http://www.rfc-editor.org/rfc/rfc1413.txt*).

- **::ident::query** *socket* ?*callback*?

  This command queries the ident daemon on the remote side of the given socket, and returns the result of the query as a dictionary. Interpreting the dictionary as list the first key will always be **resp-type**, and can have one of the values **USERID**, **ERROR**, and **FATAL**.  These *response types* have the following meanings:

  - USERID

    This indicates a successful response. Two more keys and associated values are returned, **opsys**, and **user-id**.

  - ERROR

    This means the ident server has returned an error.  A second key named **error** is present whose value contains the **error-type** field from the server response.

  - FATAL

    Fatal errors happen when no ident server is listening on the remote side, or when the ident server gives a response that does not conform to the RFC. A detailed error message is returned under the **error** key.
