# getpeername(1)

get name of connected TCP/IP peer

## NAME

getpeername - get name of connected TCP/IP peer

## SYNOPSIS

**getpeername** \[**-n**\] \[**-p** *protocol*\]

## DESCRIPTION

**getpeername** prints the IP address and service name (port number) of the remote peer connected to standard input. The IP address and the service name are printed on the same line, separated by one space.

## OPTIONS

- **-n**

  Don't translate IP addresses and port numbers to names.

- **-p *protocol***

  Force getpeername to use *protocol* as the protocol when translating port numbers to service names. *Protocol* can be **tcp** and **udp**. Normally, getpeername automatically determines what type of socket it is connected to.

## SEE ALSO

**getpeername**(3).

## BUGS

Only works on IP sockets.
