This project consists on recreating the NetCat in a Server-Client Architecture that can run in a server mode on a specified port listening for incoming connections, and it can be used in client mode, trying to connect to a specified port and transmitting information to the server.
TCP connection between server and multiple clients (relation of 1 to many).
A name requirement to the client.
Control connections quantity.
Clients must be able to send messages to the chat.
Do not broadcast EMPTY messages from a client.
Messages sent, must be identified by the time that was sent and the user name of who sent the message, example : [2020-01-20 15:48:41][client.name]:[client.message]
If a Client joins the chat, all the previous messages sent to the chat must be uploaded to the new Client.
If a Client connects to the server, the rest of the Clients must be informed by the server that the Client joined the group.
If a Client exits the chat, the rest of the Clients must be informed by the server that the Client left.
All Clients must receive the messages sent by other Clients.
If a Client leaves the chat, the rest of the Clients must not disconnect.
go run cmd/main.go [port]
By default port 8989 will be used
It also possible to run the net-cat with the use of the makefile (but only with default port):
make run
For global connection (other computers in the same network) please follow next steps:
1. In terminal:
- ifconfig
2. Take the information regarding the host of the eno1 for the inet (host for global)
3. Run the program on localhost with port 27960 (will allow global communication):
- go run cmd/main.go 27960
4. To connect from the same computer to the chat:
- nc localhost 27960
5. To connect from another computer to the chat:
- nc [host fot global] 27960
