This packet trace was collected on a server while a client was connecting to the telnet service. Telnet supports remote logins and basically a telnet session is a TCP connection where:
- the keys typed by the client are sent as ASCII characters
- the server output is sent as ASCII characters
Looking at the trace below or using wireshark, can you extract some information ? Note that the 20 bytes packets that you see below are pure TCP acknowledgements that do not carry any data.
