## NAME

tcppm - TCP port mapper

## SYNOPSIS

tcppm [-d] [-l[[@]logfile]] [-iinternal_ip] [-eexternal_ip] local_port remote_host remote_port

## DESCRIPTION

tcppm forwards connections from local to remote TCP port

## OPTIONS

| -I |  | Inetd mode. Standalone service only.
| -d |  | Daemonize. Detach service from console and run in the background.
| -t |  | Be silenT. Do not log start/stop/accept error records.
| -e |  | External address. IP address of the interface the proxy should initiate connections from. By default, the system will decide which address to use in accordance with the routing table.
| -i |  | Internal address. IP address the proxy accepts connections to. By default, connections to any interface are accepted. It´s usually unsafe. Unix domain sockets can be specified with -iunix:/path/to/socket syntax (e.g., -iunix:/var/run/tcppm.sock). On Linux, abstract sockets use -iunix:@socketname syntax.
| -l |  | Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ precedes logfile, syslog is used for logging.
| -S |  | Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy crashes.

## ARGUMENTS

local_port

- port tcppm accepts connections on

remote_host

- IP address of the host the connection is forwarded to. Unix domain sockets can be specified with the syntax unix:/path/to/socket (e.g., unix:/var/run/app.sock). On Linux, abstract (fileless) Unix sockets use the syntax unix:@socketname (e.g., unix:@app.socket).

remote_port

- remote port the connection is forwarded to. Ignored when using Unix socket destination, but must be specified (use any positive value) for syntax compatibility.

## CLIENTS

Any TCP-based application can be used as a client. Use internal_ip and local_port as the destination in the client application. The connection is forwarded to remote_host:remote_port
