simplFT

This project was made for the purpose of me to learn and understand Go better and also for the Computer Networking class that I took in Fall 2017 at UPT.

The scope of this project is to implement a simple server that handles multiple clients and allows the clients to execute commands on it.

Commands

The server accepts the following commands:

//todo

Sending commands via netcat

To grab a file the following command can be send:

echo "get file.txt" | nc ip port > lfile.txt

If someone wishes to send multiple commands, the following syntax can be used:

(echo "get file1.txt" & echo "get file2.txt") | nc ip port > concatenated.txt

Configuration

The server can be configured via command line flags with the -ConfigPath option, specifying a path to the configuration file. If no configuration file is provided the server will run with the default settings.

Sample Configuration File:

{
    "address": "localhost",
    "port": "8080",
    "maxDirDepth": 30,
    "absoluteServePath": "/Users/denis/Dropbox/Pictures/CuteAvatars",
    "pic": {
        "color": false,
        "x": 0,
        "y": 0
    }
}

The config.json file contains the following settings:

1. address - The address on which to serve

2. port - The port

3. maxDirDepth - The maximum depth the user can go into directories. A value of 30 means the user can cd into max 30 dirs.

4. absoluteServePath - The path from where to serve the files.

5. pic - The X and Y max size for the pic command. A value of 0 means original size

If one of the settings are changed, the server will reload the configuration. Except for the absoluteServePath.
