# tcplisten(1)

general TCP/IP server

## NAME

tcplisten - general TCP/IP server

## SYNOPSIS

**tcplisten** \[**-irv**\] \[*localaddr*\] *port*

## DESCRIPTION

**tcplisten** waits for a TCP/IP connection on *port*. If a *localaddr* parameter is given, **tcplisten** will bind to that IP address.  Otherwise **tcplisten** will accept connections to any of the local machines IP addresses. Data received from the client is printed on standard output, and data read from standard input is sent to the client. When end-of-file is reached on both standard input and the TCP/IP connection, **tcplisten** terminates.

## OPTIONS

- **-i**

  Terminate at end-of-file on standard input; don't wait for the client to close the connection.

- **-r**

  Terminate when the remote client closes the connection; don't wait for end-of-file on standard input.

- **-v**

  Verbose mode. Prints a message to standard error about the origins (host and port) of the client.
