Tole sem pustil zaenkrat not, da lahko hitro najdem stvari, ki jih moram se dopolnit oziroma jih moramo se predebatirat. V koncni verziji se bom teh kratic znebil in tudi tega komentarja v slovenscini :)

TODO Zakaj syslog

Eneraptor is designed in a way that it could communicate with any device regardless of its operating system. Syslog, system for logging program messages offers a quick and easy solutions for such communications, because it allows separation of the software that generates messages from the system that stores them and the software that reports and analyzes them. It could refer to syslog protocol (TODO described below),

p. We will be using syslog-ng (I will be referring to it as syslog from now on), which has a few advantages over conventional syslog. Syslog daemon will run on proxy server. TBD it will be listening on a certain port for incoming messages from client(s). Our main syslog client will run on FRI-SMS system.

p. In client mode, syslog-ng collects the local logs generated by the host and forwards them through a network connection to the central syslog-ng server. Clients can also log the messages locally into files.
