# telnet-proxy(1)

create a TELNET debugging proxy

## NAME

telnet-proxy - create a TELNET debugging proxy

## SYNOPSIS

**telnet-proxy** \<**remote address**\> \<**remote port**\> \<**local port**\>

## DESCRIPTION

**telnet-proxy** creates a single-connection proxy listening on *local port* which forwards connections to *remote address* on port *remote port*.  All TELNET commands will be logged to **stdout** for debugging purposes.

Only a single active connection is allowed at any given time.  However, after a client has disconnected, another client may connect through the proxy.

**telnet-proxy** is capable of transparently decoding and reencoding streams compressed with MCCP2.  It also includes specialized decoders and debug output for NEW-ENVIRON, TTYPE, ZMP, and MSSP subnegotiation commands.
