Prepare a Linux environment and build the server, client, and user-management utility.

Platform support

Easy RSH relies on POSIX APIs including fork, execvp, pipe, chdir, waitpid, signals, and BSD sockets. Linux is the primary supported environment. On Windows, use WSL or a Linux virtual machine rather than compiling the project as a native Win32 application.

Install dependencies

Ubuntu and Debian

sudo apt update
sudo apt install build-essential libssl-dev make

Fedora

sudo dnf install gcc-c++ make openssl-devel

Arch Linux

sudo pacman -S base-devel openssl

Build targets

The root Makefile compiles with C++17 and links against pthread, SSL, and crypto.

Command	Result
`make`	Builds `server`, `client`, and `adduser`
`make server`	Builds only the server
`make client`	Builds only the client
`make adduser`	Builds only the user utility
`make DEBUG=0`	Enables optimized release flags
`make clean`	Removes compiled objects and primary binaries

The default development build uses -g -O0 -DDEBUG. Release builds use -O3 -DNDEBUG.

Verify the output

After a successful build, the repository root contains:

./server
./client
./adduser

Display the server's options before configuring a live instance:

./server --help

Rebuild after changes

For a clean development rebuild:

make clean all

Object files are placed under build/. The source tree remains split into src/server, src/client, and src/socket with public interfaces under include/.
