# fstrm\_replay(1)

Replay saved Frame Streams data to a socket connection.

## NAME

fstrm\_replay - Replay saved Frame Streams data to a socket connection.

## SYNOPSIS

**fstrm\_replay -t *content-type* -r *file* \[ -r *file* ... \]**\
 	**\[ -u *socket-path* \] \[ -a *IP* -p *port* \]**

**fstrm\_replay --type *content-type***\
 	**--read *file* \[ --read *file* ... \]**\
 	**\[ --unix *socket-path* \] \[ --tcp *IP* --port *port* \]**

## DESCRIPTION

**fstrm\_replay** connects to a Frame Streams receiver on either the given UNIX domain *socket-path* or TCP *address* and *port*, then reads and sends data of the supplied *content-type* from the given *file(s)*.

## OPTIONS

- **-t *content-type* \| --type *content-type***

  Specify the *content-type* to read from files and send to the Frame Streams socket. Files whose content-type differ are skipped. If the socket server does not accept the *content-type*, **fstrm\_replay** will fail.

- **-r *file* \| --read *file***

  Read data from *file*. Multiple files can be given with multiple **-r** options. Files which cannot be opened, or do not contain valid Frame Streams data will be skipped.

- **-u *socket-path* \| --unix *socket-path***

  Connect to Unix domain *socket-path* to write Frame Streams data. Only one of **-u** or **-a** may be given.

- **-a *IP* \| --tcp *IP***

  Connect to TCP address *IP* to write Frame Streams data. Only one of **-u** or **-a** may be given. Use of **-a** requires a port given with **-p**.

- **-p *port* \| --port *port***

  If **-a** is given, use TCP port *port* to write Frame Streams data.

## EXAMPLES

Replay dnstap data over UNIX domain socket:

```
	fstrm_replay -t protobuf:dnstap.Dnstap \
		-u /var/run/named/dnstap.sock -r dnstap-log.fstrm
```
