A very SASL hello world.
Just running make should take care of all building needs, provided all
dependencies needed are installed. It will create two executables: client
and server.
SASL is fundamentally geared toward networks, so this isn't a "hello world" in the traditional sense. Think of it more as an echo server.
First, configure the desired SASL mechanisms in /etc/sasl2/sasllo.conf. One possible configuration is:
mech_list: ANONYMOUS PLAIN
To run the system, first pick a port (like 9001). Then launch the server:
$ ./server 9001
and in another shell, launch the client:
$ ./client 127.0.0.1 9001
If you are not running the client and server on the same machine, replace 127.0.0.1 with the address of the machine running the server.
client reads messages from stdin, delimited by the end-of-file character (C-d in most shells). If your message does not end in a newline, your shell may require you to press C-d twice.
server logs all messages it receives to stdout, and sends them back to client, which also logs all messages it receives to stdout.
Yes. This application should not be considered secure.
