Hi all,

I'm curious if there's a list of supported protocols that can be replayed with TCPReplay. I've tried recording myself sending an email and replaying it with no luck. Would that mean SMTP protocols are unable to be replayed? Are their other protocols that cannot be replayed using that?

Off topic for this site as tcpreplay is not part of the Wireshark project. The tcpreplay project site may have more info or offer support.

Hi chuck actually this is a different question regarding what protocols are supported by tcpreplay.

First of all, tcpreplay is not part of Wireshark. For documentation see

As you can read there tcpreplay simply puts the frames from a capture on the wire, regardless of what protocols these frames contain. So strictly speaking tcpreply does not support any protocol, only frames.

That is fine to test network equipment but not if you want a server the accept and respond to that traffic. Take a look at tcpliveplay for that.

SNMP is a simple text based protocol, It is a lot simpler to write you own program, in any language, than try using tcpliveplay.
