how to stream rtmp to rtmp

[Koze]

Hello,

I have for example following stream:

"rtmp://stream.smcloud.net/live2/wawa/wawa_720p" -a "live2/eskatv" -f "WIN 11,9,900,170" -W "http://www.eska.tv/thrdparty/flowplayer/flowplayer.rtmp.swf" -p "http://www.eska.tv/player" --live -y "eskatv_360p"

and would like to re-stream to another rtmp using ffmpeg on Linux Debian. Do I need any other program than ffmpeg to do the task?

Could you kindly check my below command if is correct one?

ffmpeg -re -i "rtmp://stream.smcloud.net/live2/wawa/wawa_720p" -a "live2/eskatv" -f "WIN 11,9,900,170" -W "http://www.eska.tv/thrdparty/flowplayer/flowplayer.rtmp.swf" -p "http://www.eska.tv/player" --live -y "eskatv_360p" -codec copy  -f flv rtmp://xxxxxxx

If not what would be the way to re-stream above source?

Thank you in advance for any suggestion.
