[SOLVED] SSH'ing to multiple virtualbox guests

alsaf · 01-26-2014, 05:06 AM

I am fairly knowledgeable on the Cli but I'm a total noob with networking.

I got a networking tutorial that requires 3 virtualbox guests to be setup in an internal network (A is setup as NAT and Internal network with B and C setup as Internal network). I've just started it and still getting my head round the concepts of networking but I thought it would make it a bit easier if I could ssh into all 3 guests from the cli of my Ubuntu host using GNU Screen or Byoubu rather than having to Alt+Tab to each guest.

I have openssh-server installed on guests A, B and C and when all guests are set to NAT only I have access them through host by following command:

ssh -p 3022 hosta@127.0.0.1

However when I change the guests to network settings described above, I am unable to ssh into them from my host. Is this possible?

For info: Here is the settings for each guest:

Found solution.

For instance if you want to ssh from hostA to hostC, you would go into hostc and get IP address via

Quote:

ip addr

In hostA you simply ssh into it via the following:

Quote:

ssh -p 22 hostc@192.168.1.18
