Generate ssh key-pair for Bamboo (when Bamboo uses a stupid Java implementation of git)

The Problem

Bamboo (at least the instance I have to work with) is using a Java implementation of git (JGit) that has problems reading the new SSH key-file format.

In earlier versions, ssh-keygen generated private keys that looked like:

-----BEGIN RSA PRIVATE KEY-----
...

-----END RSA PRIVATE KEY-----

Hyper-V dynamic ports fix

Hyper-V uses dynamics port range to bind some ports. This range is so low that e.g. port 3306 can be used by it. To set the dynamic port range to begin at port 49152 use:

netsh interface ipv4 set dynamic tcp start=49152 num=16384

To show the current setting use:

netsh interface ipv4 show excludedportrange protocol=tcp

Rust Notes

Safe conversion from u32 to i32:

use std::convert::TryFrom;

fn main() {
    let good: u32 = 50;
    let ok: i32 = i32::try_from(good).unwrap();
    println!("{} -> {}", good, ok);
