The Netsukuku Console *should* work now! However! I have not set up anything inside of netsukuku to actually read and respond to these commands, So, It is useless currently. Please feel free to edit this or provide suggestions about things I may be doing wrong! I've never done IPC before! Thank you for reading! ^_^
