Introducing rgaas
RGaaS - Random Generator as a Service
rgaas-server is a service that generates random bytes (using rand() which is not a cryptographically secure generator). The length of the random byte sequence can be specified by the client. The server can handle multiple random number requests per connection, can handle multiple connections, serves the clients via TCP/IP and can be run as a daemon.
rgaas-client is a client to test rgaas-server (connect, request and display multiple random byte sequences of a user-specified length).
Installation from source
Prerequisites
The following tools are necessary for building:
cmake(3.23)clang(14.0.5)
How to build
Invoke the following commands:
$ cmake .
$ cmake --build .
which will build rgaas-server and rgaas-client executables. You can find them in the build folder.
Quickstart
Invoke the following commands (daemon mode):
$ ./build/rgaas-server -p 8000 -v -d
$ ./build/rgaas-client -n <hostname> -p 8000 -v
Note: you will need to send SIGINT to the process of rgaas-server to kill it:
$ kill -INT $(pidof ./build/rgaas-server)
Invoke the following commands (foreground mode):
$ ./build/rgaas-server -p 8000 -v
Open an other terminal:
$ ./build/rgaas-client -n <hostname> -p 8000 -v
Example
$ ./build/rgaas-server -p 8000 -v
15 rgaas - program started
15 rgaas - tcp setup successful
$ ./build/rgaas-client -n fedora -p 8000 -v
15 rgaas - program started
