### TCP client & server (C++20 & Boost.Asio)

This is one of the cool tasks from my university

### Task description

Implement a multi-threaded client-server application under Linux.

- Client is a program launched from the console

- The server is a daemon that gracefully terminates on `SIGTERM` and `SIGHUP` signals

- The client must transfer the contents of the text file via TCP

- The server must accept connection and save TCP stream to a file

### Requirements

- cmake

- conan

### Building

```bash

./build.sh

```

### Integration with CLion

By default, this may result in an error, to fix this:

1. execute `cd cmake-build-debug && conan install ..`

2. refresh CMake build

### Server

```bash

# run server at port 1234

./build/bin/server 1234

# check that daemon started

lsof -i :1234

# connect to server using netcat

echo "some data" | nc -N 0.0.0.0 1234

# read logs of the daemon

grep tcp_server_daemon /var/log/syslog

# clear syslog

sudo truncate -s 0 /var/log/syslog

```

### Client

```bash

# generate random file

head -c 1G  large

sha256sum large

# send file to the server

./build/bin/client 127.0.0.1 1234 large

```
