SSH into VirtualBox on Mac

hadooplinuxsshvirtualbox

I just installed VirtualBox on my mac, created a new Ubuntu Virtual Machine with "Use an existing virtual hard disk file" of the Cloudera Hadoop disk image. I'm able to start and run the virtual machine, however, I'd prefer to ssh into from my terminal. The following produces the message "connect to host 127.0.0.1 port 2222: Connection refused":

ssh root@127.0.0.1 -p 2222

I've also tried -p 22

I've also tried using "cloudera" as the user. Is there a VirtualBox setting I need to change to allow SSH?

I've also just tried to create a new linux virtual machine without using Cloudera disk image, and I can SSH into that either.

I have a Mac on which I had installed VirtualBox.

So this is what worked for me ...

Click on the cloudera image and click settings Click on Network -> Adapter 1(by default have attached to as NAT) -> Advanced -> Port Forwarding Add a new entry (click on + to add) with the following settings:

Host Port: 1111, Guest Port: 22, leave the host IP and guest IP blank

Connect from your Mac cmd shell using the following

ssh -p 1111 cloudera@localhost

At Ubuntu 18.04 additionally install ssh and reboot

sudo apt-get install openssh-server

Partition Virtual Machine – Convert Partition Image to Disk Image with Partition Table

You can do this on the host machine. Most tools like fdisk will operate on files, and kpartx gives you access to partitions in a file.

Create a new empty 100GiB sparse image (make this slightly bigger than the size of the partition image)
```
dd if=/dev/zero of=myvm.img bs=1G count=0 seek=100
```
Partition the image file with fdisk
```
fdisk myvm.img
```
Make the partitions in the image file available is individual devices
```
sudo kpartx -a myvm.img
```
Copy the partition image into the partition
```
sudo cp image.bin /dev/mapper/loop0p1
```
Extend the filesystem to fill the entire partition
```
sudo resize2fs /dev/mapper/loop0p1
```
Close the partitions
```
sudo kpartx -d myvm.img
```
Dismantle the loopback device
```
sudo losetup -D
```

Ssh from linux into mac – permission denied

Your username in the VM is different than your username on the Mac. By default, ssh assumes the usernames are the same if you don't specify it explicitly. It's trying to log in to a user that doesn't exist (or that you haven't set up), which is why it always fails.

To avoid that, you can either specify the username each time, or set up your .ssh/config file in the VM like this:

Host mac
    Hostname macdomain
    User yourmacusername

That will override the default username for that host only. You would also be able to just ssh mac if you prefer, rather than using the hostname.
