The bot just parses the logfile continuously and responds to certain chat texts and events via rcon chat or commands.
You should get answers to all the ! commands, at least when you type !help. Apart from that, the bot is not visible ingame.
Since you posted a loopback adress, I assume sg and b3 are running on the same machine? If so, there should be no connection problems.
Last thing I could imagine is some disfunciotnal antivirus. Permissions should not matter either.
OffTopic: I see some fancy typos/grammar mistakes in b3's output
