Wireshark-users: Re: [Wireshark-users] Understand wireshark data

Not being an expert on TELNET (are they any?), I imagine that http://www.ietf.org/rfc/rfc854.txt might be a useful cross-reference. If you open the Wireshark details pane, you should be able to see how the Telnet commands map to actual values contained in the packet. You should be able to confirm your assumptions there.

Hi. Okay I have captured data with wireshark. I am trying to understand telnet commands to send to my telnet server. (You know things like IAC, DO, WILL WONT, etc).

For one packet, in the packet details window under the node "Telnet" node I saw something written like:

Command: Will Terminal Type
Command: Will Negotiate About Window Size

Does this translate to

IAC WILL [Terminal Type] IAC WILL SB [Window size]

Is it one sequence of instruction or two instructions?
