# tracereplay(1)

Replay a trace in trace time from one uri to another

## NAME

tracereplay - Replay a trace in trace time from one uri to another

## SYNOPSIS

**tracereplay** \[-b \| --broadcast\] \[-s --snaplength \[ snaplength\] \]  \[-f \| --filter \[ filter string \] \] inputuri outputuri

## DESCRPTION

tracereplay replays inputuri to outputuri in trace time. Checksums are  recomputed on the fly.

- **-b**

  - **--broadcast**

  Change the 802.3 (ethernet) destination address to the broadcast address.  This will send the transmitted packets to any hosts on the local network.

- **-s***\[snaplength\]*

  - **--snaplength***\[snaplength\]*

  Truncate the packets to the length specified. This only makes a difference if the inputuri is a capture device. The value should be \> 0. Inappropriate  values will be ignored, but a warning will be printed.

- **-f***\[***filter***string***\]**

  - **--filter***\[***filter***\]*

  Apply a filter to the inputuri.
