Tuesday Class Protocol Specifications

User changes alias to <alias>, server broadcasts name change to everyone.

User types: /name <alias>
Server receives: NAME <alias>

Server sends alias (if set), and IP address of person of interest only to user who requested.

User types: /whois alias|IP
Server receives: WHOIS <alias|IP>

Server broadcasts message with the format “<alias|IP>: <message>” to everyone.

User types: <message>
Server receives: MSG <message>

Server closes user connection, server broadcasts “user left chat” message to everyone.

User types: /quit
Server receives: QUIT

Server sends local time to user who requested.

User types: /time
Server receives: TIME

Server sends alias and IP address to user who requested.

User types: /whoami
Server receives: WHOAMI

Server broadcasts new connections with “user joins chat” message to everyone, and when user opts to change alias, user keeps alias until the end of his/her session (i.e., when user 10.158.22.99 changes own alias to “AriesBestGrill” and disconnects, when user reconnects, user is back to 10.158.22.99).

Additional Notes

PS: the name 'Hana' which can be seen multiple times in the code is a reference to 'Hana Song' from 'Overwatch'
