Summary

High-performance /sbin/init program for Linux

This is designed to do literally nothing but accept binaries over the network and run them as a child of init.

If you pipe a file to <server ip>:1234 it will run it and pipe the stderr and stdout back to you

If you connect to <server ip>:1235 init will send SIGKILL to all processes on the system but itself. This is a measure to allow resetting the system if a binary was uploaded that had issues. This port neither sends or recieves anything, it simply kills upon getting a TCP connection.

For a simple headless Linux machine running a basic kernel, you'll want flags like this:

console=ttyS1,115200 rw root=/dev/sda ip=dhcp

This enables a console on ttyS1 (in my case that's COM2, the Serial-over-LAN port for IPMI), rw specifies that the root mount should be read-writable (required since we drop a file), root specifies the root filesystem device (in our case we used an unpartioned flash drive with vfat), and ip=dhcp is the coolest part, this allows the kernel to get a DHCP lease on any active NICs. This is mandatory because we use networking in init without any configuration of the network.

TL;DR: Build a kernel that can read from your drive and do networking, put this on it at /sbin/init, boot the kernel and it will run this program.

    Documentation Incorrect

    Documentation claims "If you connect to :1235 init will send SIGKILL to all processes on the system but itself. This is a measure to allow resetting the system if a binary was uploaded that had issues. This port neither sends or recieves anything, it simply kills upon getting a TCP connection."

    Connection to port 1235 actually responds with "Kill command received, sent SIGKILL to all processes\n" if it can.
