# The `s6-ident-client` program

`s6-ident-client` is a command-line client application that performs IDENT (RFC 1413) queries.

## Interface

         s6-ident-client [ -t millisecs ] remoteaddr remoteport localaddr localport

- s6-ident-client contacts the IDENT server on address remoteaddr port 113 and asks it about the connection from address remoteaddr port remoteport to address localaddr port localport.
- It prints the answer to stdout.
- It exits 0 if the answer is positive or 1 if the answer is negative, in which case it also prints an informative message to stderr.
- remoteaddr and localaddr can be either IPv4 or IPv6 addresses; however, they must both be of the same type.

## Options

- `-t millisecs` : if no answer has been obtained within millisecs milliseconds, s6-ident-client will exit 99 with an error message. By default, millisecs is 0, which means no time limit.
